fictional dates of the old solar system

[ + links to:  Brackett, Bradbury and "past-future" dates  -  Synchronicities of 1967  -  The chronology of Captain Future  -  Looking ahead with excitement to 1981  -  Uranian Eras ]


The dates of imagined events lend interest to a story, and help to characterize it. 

If the dates are still in our future, they link the tale to us via the chain of year-numbers. If on the other hand the dates are in our past but in the author's future (like, for example, stories written in the 1930s but set in the 1980s), they piquantly contribute to the history of expectations - 

Harlei:  Or to put it another way, the history of what might have been. Particularly in our sub-genre!  The entire OSS is a rich field for nostalgic might-have-beens.  "If only the planets had been habitable / inhabited, if only cheap space travel had been invented, if only this, if only that."  To give a date to a fictional event is to rub in the "if-only" with extra bitter-sweetness.

Zendexor:  And yet you get some critics who complain that dating a story makes it 

Harlei:  They just don't get it.  Like those who say that Apollo 11 destroyed the readability of fictional first journeys to the Moon because it made them "out of date", as though from July 1969 onwards readers might as well throw  Operation Columbus into the trash bin.  I'm not trying to knock reality, I realize it has its points, but Operation Columbus actually has Apollo 11 beat hollow -

Zendexor:  Well, we can simply say to all that, "Fiction is reality.  A book is a thing that exists.  The ideas in it exist - "

Harlei:  - though it's a pity Hugh Walters doesn't give us a date for the events in Operation Columbus...

Zendexor:  Never mind, we do have the dates of other first-trips-to-the-moon (for example see below, under "1975", "1978" and "2026").

And there are some dates which refer to the far more distant past, since the OSS is really old - that is, it's backed in its own terms by a venerable timeline, as well as "old" in the other sense of being outdated.

Future researchers might model a two- or even three-dimensional "date-space" as outlined in the Diary, Complex Dates.  And if that ever happens, maybe the following list may be of some use as a starter.

One last point: at first the timeline was solely concerned with OSS science fiction, but now I put interstellar events in as well, whenever I come across them; and also some non-OSS solar system stuff (e.g. from Robinson's Mars trilogy).  Such inclusivity should allow interesting comparisons to be made.

Happy browsing, folks.

As best he could, he selected a line in the set corresponding to Anno Domini 1535.  Auri linked fingers with him and followed him trustingly through the curtain.

Again the long, still room, and the locker.  But the clothes stored here were something else from the Neolithic.  A variety of costumes was available, peasant, gentleman, priest, soldier, and more.  He didn't know which was best.  What the hell had gone on in Denmark of the sixteenth century?  Hell indeed, if the time war were involved...

On November 1, 1907, there had come to New Orleans police a frantic summons from the swamp and lagoon country to the south.  The squatters there, mostly primitive but good-natured descendants of Lafitte's men, were in the grip of stark terror from an unknown thing which had stolen upon them in the night.  It was voodoo, apparently, but voodoo of a more terrible sort than they had ever known; and some of their women and children had disappeared since the malevolent tom-tom had begun its incessant beating...

Inspector John Raymond Legrasse makes his report on the Cthulhu worshippers to the American Archaeological Society at its annual meeting in St. Louis.  [The Call of Cthulhu (1928)]

From The Lion of Comarre (1949):

The First Electronic Age, Peyton knew, had begun in 1908, more than eleven centuries before, with De Forest's invention of the triode...

[Note from Zendexor: the right date for this is 1906, not 1908, if Google Search informs me correctly.  Still, we're on a fictional time-line here...]


Euthanasia made available in the US:

...It was, I remember, the 13th day of April, 1920, that the first Government Lethal Chamber was established on the south side of Washington Square, between Wooster Street and South Fifth Avenue...                        [The Repairer of Reputations, in The King in Yellow (1895)]


Birth of Hugh Macklin, the Timeliner (1955).  See 1959 and 2035.


Gustaf Johansen's encounter with Cthulhu [The Call of Cthulhu (1928)].

...Poor Johansen's handwriting almost gave out when he wrote of this.  Of the six men who never reached the ship, he thinks two perished of pure fright in that accursed instant...  After vigintillions of years great Cthulhu was loose again, and ravening for delight.


A year replete with cosmic horror in Massachusetts (threatened by malign undersea powers) and Vermont (infiltrated from space).

It was I who fled frantically out of Innsmouth in the early morning hours of July 16, 1927, and whose frightened appeals for government inquiry and action brought on the whole reported episode.  [The Shadow Over Innsmouth (1931, 1936)]

The whole matter began, so far as I am concerned, with the historic and unprecedented Vermont floods of November 3, 1927.  I was then, as now, an instructor of literature at Miskatonic University...   [The Whisperer in Darkness (1931)] 

Note: the Vermont floods really did happen.


Albert N Wilmarth discovers the dire secret of the Plutonian visitors to the wilds of Vermont.  [The Whisperer in Darkness (1931)]

18 May:  date of the letter from mining engineer Robert B F Mackenzie of Pilbarra, Western Australia, to Professor Nathaniel Wingate Peaslee, c/o the American Psychological Society, New York City, concerning worked stone blocks found in the Australian desert: artefacts so aicient that they seem to confirm the time-visions which Peaslee had published.

"Ready, Bill?" asked Harl Swanson.  Bill Kressman nodded.

"Then kiss 1935 goodbye!" cried the giant Swede, and swung over the lever.

[The World of the Red Sun (1931)]

3rd June:
It was on Monday, June 3, that we saw the first of the half-buried blocks.  I cannot describe the emotions with which I actually touched - in objective reality - a fragment of Cyclopean masonry in every respect like the blocks in the walls of my dream-buildings.  There was a distinct trace of carving - and my hands trembled as I recognised part of a curvilinear decorative scheme made hellish to me through years of tormenting nightmare and baffling research.                                      [The Shadow Out of Time (1936)]

17-18 July: dreadful confirmation of Man's place in the universe:

After twenty-two years of nightmare and terror, saved only by a desperate conviction of the mythical source of certain impressions, I am unwilling to vouch for the truth of that which I think I found in Western Australia on the night of July 17-18, 1935.  There is reason to hope that my experience was wholly or partly an hallucination - for which, indeed, abundant causes existed.  And yet, its realism was so hideous that I sometimes find hope impossible.

If the thing did happen, then man must be prepared to accept notions of the cosmos, and of his own place in the seething vortex of time, whose merest mention is paralysing...

[The Shadow Out of Time (1936)]


Nexx Agent Ravel, battling against time-manipulators for the structure of reality, travels from and to this year in Dinosaur Beach (1971).

   ...Out of nothingness, a tiny glimmer of light.  It grew, strengthened, became a frosted glass globe atop a green-painted cast-iron pole which stood on a strip of less than verdant grass.  The light shone on dark bushes, a bench, a wire paper-basket...  I was back in Buffalo, New York, in August, 1936...    


Appearance (on 5th June) of The Machine-Man of Ardathia (1927) from A.D. 29,940.


Miss Betty Mordan is reluctantly inveigled into an adventure in time with Roy Saber from 1951 [Wanderers of Time (1933)]

Interplanetary invasion:

Sergeant Evan Paige's gray, brooding eyes stared reflectively at the paper in his hand, dated three days before, June 7, 1941.  Under the official seal of Washington it read:

"Emergency draft.  All men able to bear arms, ages 14 to 55, in defense of Earth against the invaders from Mars.  Your country and your world need you.  REPORT AT THE NEAREST RECRUITING OFFICE IMMEDIATELY."

                                                                                  [One Thousand Miles Below (1940)]

From Dormant (1948):

...At the very hub of the screaming waters lay Iilah, dead now almost for ever, forgotten by time and the universe.

Early in 1941, Japanese ships came and ran the gauntlet of dangerous waters into the quiet lagoon...

From Maker of Universes (1965) we learn that the wily hero "Kickaha" alias Paul Finnegan
in 1941 the age of twenty-three... had volunteered for the U.S. Cavalry because he loved horses.  A short time later, he found himself driving a tank...

Atomic space-drive invented in secret [The Great Engine (1943)].

French scientists bring Henri Lothiere forward in time from the year 1444 [The Man Who Saw the Future (1930)].


Limited liaison between a motion-picture projector in 1946 and one in 2011.  [Film Library (1946)]

From Dormant (1948):

...Something stirred in the depths of Iilah's awareness of himself, something that he had intended to do.  He couldn't remember what.

That was the first real thought he had in late 1946, when he felt the impact of outside energy.  And stirred with returning life...

The cripple Hugh Hunter conceives the aim of an organization to catch war criminals, which later saves the world from mind-control by "Master Brug" [The Doomsday Brain (1967); see also 1955].

   ...Because he was a businessman, he hated all unfinished business...  When he spent some months in a private hospital in 1946, watching his legs wither and become useless, he had ample time to pause and think.  He drew up, for himself, a trial balance of the actual profit and loss of World War Two - not in material but in human terms.  It was then that he realized how much unfinished business still existed... 


From Seedling of Mars (1931): 

It was in the fall of 1947, three days prior to the annual football game between Stanford and the University of California, that the strange visitor from outer space landed in the middle of the huge stadium at Berkeley where the game was to be held...


From The Great Engine (1943):

THE blue-gray engine lay half buried in a green hillside.  It lay there in that summer of 1948, a soulless thing of metal and of forces more potent than life itself...


...Now he was alive again, but in so dim a fashion that there was nothing to do but wait for the end.  He waited.

In 1950 he watched the destroyer float towards him...        [Dormant (1948)]


Roy Saber sets off on his adventure in time [Wanderers of Time (1933)].


Some of the members of the 1942 Brewster expedition to the Moon now return to Earth, long after they were given up for lost [The Moon Conquerors (1930)].


According to No Man Friday (1956), p14, the Americans secretly launched the first artificial satellite in this year.   (Four years in advance of reality, and the reality differed in being not secret, of course.) 

From Evans of the Earth-Guard (1930): 1954, the first crude rocket had thundered out from earth into the great void toward its shining satellite.  Neither that rocket nor the twenty-first had reached their goal, but the next one had.


According to No Man Friday (1956) this is the year the Russians sent up their satellite - secretly, just like the Americans.  (In reality, when it did happen two years later, the Russians, who were first in space, were happy for the world to know it.)

In the preamble to Into the 28th Century (1930) we are informed that

...In the year 1955 peace was restored to the stricken planet, reconstruction began, and the World-State elected a woman, known as the World President, as its Chief Executive...

For 1955 as the present (according to John Varley) see the OSS Diary, 7th December 2016.

Colonel Lawrence Kingsley is recruited by half-blind multi-millionaire Hugh Hunter to become executive director of an organization to catch war criminals [The Doomsday Brain (1967); see also 1946]:

"There is a chair in front of you," the voice continued.  "I trust you will find it comfortable."

He sat down gingerly and waited...  As he became more used to the darkness he thought he could make out a dim figure seated opposite him; he even believed that he could trace the outline of an invalid chair of unusual proportions...  


First manned atomic rocket launched [The Legion of Space (1937, 1947), p.12].

The year Jay Vickers walked the "enchanted valley": the one to which there's no going back:
   He had carried the dream for more than twenty years and now that the dream was coming true, he saw that it was tarnished with all the time between, that there was no going back to that day in 1956, that a man never can go back to a thing he once has left...
                                                                    [Ring Around the Sun (1952, 1953)]

...and later the records show "Vickers, Jay... l.t. June 20, 1956" - l.t. standing for "life transferred"...

From the alternate history recounted in the introduction to The Psychotechnic League (1981):
   Conflict was inevitable once Eisenhower's death from surgical complications elevated Nixon to the U.S. presidency in June, 1956.  Cold War paranoia distorted Nixon's reactions to unrest within the Communist bloc in the autumn of that year.  Covert U.S. aid to the Hungarian rebels so enraged the Soviet Union that it backed Egypt past the limits of prudence during the Suez Crisis.  The savage Mideast war that followed left Socialism dominant throughout the region and the U.S.S.R. in possession of northern Iran...   


...In the year 1958, Professor Jameson had sought a plan whereby he might preserve his body indefinitely after his death...     [The Jameson Satellite (1931)]


SF authors don't claim to be prophets, but in guessing the year of the first probe to reach the Moon, Arthur C Clarke scored a direct hit in his Prelude to Space (written in 1947).  1959 was the year he said it would happen, and lo and behold, when 1959 came round, Lunik 2 hit the Moon in reality.

1959 is also the year when the mind of the unfortunate Hugh Macklin begins its temporal odyssey in Timeliner (1955).


Invasion from below by intelligent tentacled/insectoid metal-armoured creatures:

Much has been written about the terrific cataclysm of 1960 - the eruption of the volcano, Coseguina, with its accompaniment of earthquakes, fires, floods and storms, which carried death and destruction into Salvador, Hunduras and Nicaragua...

But, immense and devastating as it was, it is not of this cataclysm that I would write, but of that infinitely more terrible menace to all mankind which closely followed it - which was, in fact, loosed on the inhabitants of the earth's crust as a direct result of the eruption...

[The Metal Monster (1931)]


14th June: the first pictures from the Russian Venus lander reveal humanoid life on Venus [The Sky People (2006)].


Elmis, the disguised Martian, begins his stint in Latimer, Massachusetts.  [A Mirror For Observers (1955)]


The Black Cloud is discovered on its approach to the Solar System, by Knud Jensen working at Mt Palomar [The Black Cloud (1957)].


The catastrophic visit of the Black Cloud, and the fantastic discovery of its sentience by Cambridge scientist Chris Kingsley [The Black Cloud (1957)].

From Destination Mars (1963):

...He recalled the discovery of this distant belt of radiation by the French scientist Jules-Robert Le Prince.  Its presence had first been suspected back in 1965, when deep space probes registered an unexpected increase in radiation at a distance of some five million miles from the Earth...


This year, in my view, is the Present; what comes after is the increasingly weird future.  See the OSS Diary for 7th December 2016.

Robert Carson (1932-66), space pioneer, dies some days after his spacecraft Wanderer II is damaged by a meteor.  (Due to the trust fund established in his name he posthumously becomes, thousands of years later, The Man Who Owned the World (1961).


April 1967: victory at last is achieved for the two Anglo-Saxon powers, the USA and Britain, after the long intermittent world war which began in 1914.  Then, on 10th June 1967, comes  "Mars Day" - the first intelligible public message from Barsoom to Earth, broadcasting greetings to the world from the city of Helium.  [Prologue to The Moon Maid (1923).]

There's a strong hint in A Fall of Moondust (1961) that 1967 saw the Russians make the first Moon trip - thus celebrating the 50th anniversary of the Bolshevik Revolution.

The Uncertain Midnight (1958) has 1967 as the year of the "Nine Days Tranquiliser", a nuclear holocaust that reduces the population by a factor of roughly a thousand. 

A note in Brigands of the Moon (1930) implies that the "Yellow War" occurred in 1967.


...The Republicans have been fresh out of ideas since '968, when the Democrat Clifford got in...     [A Mirror For Observers (1955)]

...Apparently London, Paris and Rome were in telephonic communication almost without a break, and the news of the great London landslide was telephoned to Madrid and thence radioed to Buenos Aires in 1968...           
                                                                 [The Shape of Things to Come (1933)]


"...Many men lost their lives in trying to reach the Moon, and most people said it was impossible for them to do it - there was even a movement to get their attempts banned.  But the men went on trying.  Duncan, K.K.Smith and Sudden actually got there, but they crashed on the surface and were killed.  Then came the great Drivers.  In 1969 he managed to take his rocket right round the Moon and bring it safely back to Earth..."  [Stowaway to Mars (1936), p.23]

...On November 29, 1969, Robbins and Swain attempted a take-off from an Adirondack plateau.  But the erratic Wellston cyclotrons lived up to the predictions of the pessimists, and let go with a blast of power that destroyed the whole tail of the rocket and sent the main mass of the ship flying out into space with terrific impetus.  Robbins and Swain were undoubtedly killed instantly.

The wrecked craft was hurled roughly toward the asteroid Eros, and took up a loose orbit around that little world as a tiny satellite...

[Eros (1942)]

12th July 1969 is the date of the letter from civil servant Edward Powell to the U.K.'s Minister of Defence, advising the closure of the Portfield research establishment, since its efforts to develop telepathy for purposes of national security have apparently proved a failure.

   ...Although research at Portfield has added to the already considerable statistical proof of the existence of Telepathy, it is - in Doctor Havenlake's opinion - highly unlikely that this erratic, and quite unpredictable force will ever be sufficiently developed to be of use in the practical manner for which we had hoped...            

In actual fact Portfield's discoveries have been all too successful from the telepaths' point of view, and its closure suits them well...          [The New Minds (1967)]


On 27 February 1971 Howard Lester, narrator of The Philosopher's Stone, under goes the operation on his pre-frontal cortex which increases his willpower...

In Captain Future's Challenge (1940) 1971 is cited as the date space exploration began:

Gravium was the very life-blood of interplanetary civilization.  For without it, gravitation-equalizers could not be made.  And without equalizers, men didn't dare visit other planets of greater or lesser gravitation than their own.

The first space explorers, back in 1971, had found that out.  Landing on worlds of lesser gravitation than Earth, their circulation, internal organs, their whole anatomy, were damaged.  All were sickened, many crippled and killed...

The Omega Radiation begins (over the next decade its effect on mental health results in the death of most of the population).  Possibly related is the action of Matthew Greville who crashes his car on 7th July at Chelsea Bridge, London [All Fools' Day (1966)]:

July 7th, 1971.  Two-thirty a.m.  The air warm, clear patches of sky loaded with stars, and the Thames rippling quietly through the subdued noises of London like a jet and silver snake.
   Two-thirty a.m.  A car whispering sweetly, as cars do in the moist hours of darkness.  A car, a man and a woman, routed for Chelsea...    


The last mighty air war of 1972, which had ended in the total abolition of all national boundaries and the establishment of the World Government with its headquarters in the new world-capital of New York, had brought peace to the world, but it had also brought some measure of monotony...   [The Universe Wreckers (1930)]

The great plague is released by an unbalanced member of the Organic Unity Party [A Mirror For Observers (1955)].


First trip to the Moon - but no return to Earth [Blindness (1935)].

Anti-science measures enacted in the first session of the 93rd Congress [Trends (1939)]:

...the famous Stonely-Carter Bill was passed.  It established the Federal Scientific Research Investigatory Bureau - the FSRIB - which was given full power to pass on the legality of all research in the country.  Every laboratory, industrial or scholastic, was required to file information, in advance, on all projected research before this new bureau, which could, and did, ban absolutely all such as it disapproved of...    

Catastrophic earthquake, the greatest in historic times [The Great Nebraska Sea (1963)]:

...It had been a particularly hot and dry August, and the Forestry Service was keeping an anxious eye out for the fires it knew it could expect.  Dense smoke was reported rising above a virtually uninhabited area along Black Squirrel Creek, and a plane was sent out for a report.

The report was - no fire at all.  The rising cloud was not smoke, but dust...

...By September 23rd the Fault was active well into Wyoming on the north, and rapidly approaching the border of New Mexico to the south...

...All through October, hollow-eyed motorists flocked into Tulsa, Topeka, Omaha, Sioux Falls and Fargo...

...Today, nearly one hundred years after the unprecedented - and happily unrepeated - disaster, it is hard to remember the terror and despair of those weeks in October and November, 1973.  It is inconceivable to think of the United States without its beautiful and economically essential curve of interior ocean...      


The anti-science act of the previous year (see under 1973) is challenged [Trends (1939)]:

The inevitable appeal to the supreme court came on November 9, 1974, in the case of Westly vs. Simmons in which Joseph Westly of Stanford upheld his right to continue his investigations on atomic power on the grounds that the Stonely-Carter act was unconstitutional...

It was rumoured at first that the court would declare the act unconstitutional, and monster parades were held in every large town against this eventuality.  The League of the Righteous brought its powerful influence to bear - and even the supreme court submitted.  It was five to four for constitutionality.  Science strangled by the vote of one man  


At 0150 G.M.T. on December 1st, 1975, every telephone in the world started to ring....         [Dial F for Frankenstein (1962)] - full telephone interconnection unexpectedly creates an emergent intelligence.

Selenite ruins on Farside are "discovered by the circumlunar expedition of 1976" - see The Archives of the Moon.

First Mars expedition discovers the Doorway:  an interstellar transportation system.

It was a cubicle of something that looked like slick brown glass.  Ten feet high, six wide and deep.  Inside, at waist level, on the far wall, a lever - curiously shaped, like the head of an old-fashioned walking stick, the slightly curved bar of the L parallel to the wall.  Nothing more than that...                                                                                               [Ticket to Anywhere (1952)]

...She seemed to be aware of all the pitfalls, and though Dayles' agents kept a complete check on every statement and speech that she made in public, the months went by and she did not slip, and she did not fall.

Dayles observed the performance from a distance, at first with disbelief and then with admiration, but finally with alarm.  "She's got to get tired," he said.  "One of these days she'll be so exhausted she can scarcely stand, and that's the moment for our people to trip her up."

Whatever could be said about the rationality of the candidate did not apply to her followers.  The millennium was about to arrive.  Women could end war, bring peace to the troubled world.  They would right the wrongs of society, control the rapaciousness of business, and once and for all they would end the infidelity of the American male...

[Moonbeast (1963)]

Neville Yeadon, unaware that his mind is soon to be translated to Uranus, is enjoying his lunch hour and the thought that he won't have to work at Kagan Cartons much longer:

The fact that I'll soon be employed elsewhere has, paradoxically, brought back to me some of the buzz I used to derive from working in central London.  Call it the Affectionate Departure Syndrome, with the affection dependent upon the departure.

Nevertheless - it's funny - a week and a half has gone since I gave in my notice at Kagan Cartons, and still I can hardly believe I'm free.  The benign, slow-motion bombshell of Fact is only gradually blasting its way into my intelligence; the full delight of its truth has yet to seep in through every mental pore.  All the same, there's no room for doubt; I've been reliably notified of my good fortune.  So, while Britain swelters, and cold drinks do a roaring trade, I swig the draught of secret happiness.  In future years, while the country remembers 1976 for its heatwave, I shall remember it for my release...

From The Immeasurable Horror (1931):

I was with the first Venusian expedition, under the leadership of Admiral Carfax, in 1977.  We were able to make no more than a mere landing, and were then compelled to return earthward because of our shortage of oxygen, due to a serious miscalculation regarding our needs.  It was unsafe, we found, to breathe the thick, vapor-laden air of Venus for more than short intervals...

From Blindness (1935):

...Garnall was drowned in Lake Erie, after returning from Luna, the first man to reach Earth again, alive.  He didn't go on living, of course, but he was alive when he reached Earth.  That we knew.

From Martian Blood (2013): one knew for sure whether the planet was inhabited until Ares I landed there in 1977...

11th August 1977:  Floyd Jones born, in Colorado [The World Jones Made (1956)].

The Refuge is constructed in that same year (p.6) - a building containing a simulation of the Venusian environment, to house a group of people biologically engineered in preparation for that environment.

From The Overman Culture (1971), p.173, the testament of the Mormon, Julius Overman, begins as follows:

"I was born in the year 1977 in London, England, to which corrupt and decadent country I shall not return until time and the will of God have wrought great and cleaning changes..."

From Theory of Rocketry (1958):

...Mr. Edel taught six English classes that year at Richard M. Nixon High School, and the classes averaged seventy-five pupils each...

1977 is the year in which the action of Ring Around the Sun (1952, 1953) takes place.

It had been the blade at first, the razor blade that would not wear out.  And after that the lighter than never failed to light, that required no flints and never needed filling.  Then the light bulb that burned forever if it met no accident.  Now it was the Forever car...     


The year of the first voyage to the Moon in both Prelude to Space (written in 1947) and The Man Who Sold the Moon (1949, 1951).  Also it is the year of the first flight round the Moon, albeit without a landing, in Trends (1939).

Regarding The Man Who Sold the Moon: the date of the flight is not given in the story itself, but it appears in Heinlein's own Future History time-chart:  "First rocket to the Moon, 1978".

From Frogheads (2015):

"You've been on Venus thirty years?"  Ronson seized the chance to change the subject.  "That means you would have belonged to one of the first expeditions."

"Da."  He nodded vigorously.  "Second expedition, 1978.  Chief petty officer, Soviet Space Force."

From Trends (1939):

The nadir of science came in the spring of 1978, a bare month before the completion of the New Prometheus, with the passing of the 'Easter Edict' - it was issued the day before Easter.  By it, all independent research or experimentation was absolutely forbidden.  The FSRIB [see 1973] thereafter reserved the right to allow only such research as it specifically requested.

 - However, that same year the first successful circumlunar flight, carried out in defiance of authority, brings about a popular change of heart.


From The Immeasurable Horror (1931), narrating the Second Venusian Expedition:

In 1979 we went back, more fully equipped for all contingencies this time, and landed on a high plateau near the equator.

It was also, in Master of the Asteroid (1932), the year of the disappearance of the Selenite,

...the first known rocket ship to dare the zone of the asteroids.

At the time of its disappearance, fifty years ago, in 1980, a dozen voyages had been made to Mars and a rocket base had been established in Syrtis Major...

In 1980 was passed the UN Extraterrestrial Protection Act [The Sky People (2006), p108].

On page 40 of The Simulacra (1964) we learn that the "fracas of 1980" saw the Oregon-North California region hit by Red Chinese guided nuclear missiles.

From The Universe Maker (1953):

"We Shadows," she began, "are trying to undo the effects of the psychological disaster that demoralized the human race, beginning in the Twentieth Century.  The pressure of civilization was apparently too much for millions of people.  Everywhere men sought to escape and they found the means late in 1980 in the newly invented floaters....

From an article in Captain Future Spring 1941:

...The Mercurians had attained a certain civilization before ever the first Earthmen had opened the spaceways and visited the planet, in 1980.  They did not have the mighty past of the Martians, but they had achieved progress commensurate with their numbers...

...a strangely shaped piece of metal, showing the coloration of intense heat.  It was, in its way, the most pathetic of all these symbols from the past, for it told of Man's greatest achievement and of the future he might have known.  The mahogany stand on which it was mounted bore a silver plate with the inscription:

"...The Treaty of Santa Fe, signed at the ancient New Mexican city in 1987, partitioned the Solar System.  Venus was granted to the Sino-Nipponese Empire, which America had re-established after World War III.  Mars was assigned to the Western Union of Europe, then dominated by Germany.  The satellites of Jupiter, believed to be unreachable and absolutely valueless, went as a contemptuous sop to Russia, which had been too far enfeebled by war and its own Soviet rule to resent such an insult.  Luna alone was reserved for America..."

In Indoctrinaire (1970, 1979), 1989 is the year of World War Three:

   In July 1989...  the first stage of the war took place when the post-revolutionary Cuban society invaded the south-eastern tip of the United States...  For eight incredible days, the tiny force of Cubans, representing virtually the whole of the country's armed forces, had fought their way three hundred miles up the Floriday peninsula.  Cape Canaveral had fallen to them, and the space-centre destroyed.  Finally, in a massive counter-attack, in which the Americans had used almost every kind of weapon available to them, the invasion force had been wiped out...


June 1990: Roger and Elaine Newton, hunted by bad guys who want to steal Newton's inventions, decide to seek refuge on the Moon.  Elaine is pregnant with the son who will become Captain Future.  See chapter 2 of Captain Future and the Space Emperor (1939, 1967).  (Interestingly, although there are planetary colonies, the Moon has been left alone so far, being considered useless.)

"Ten weeks later" they set off for the Moon.  And there, "a little later" (i.e. probably still in 1990), their baby boy Curtis is born.

Geological upheavals hugely damage the Earth, setting the scene for Mal Irish's adventure the following year in Catastrophe Planet (1966):

"...The fall of '90.  I was on satellite duty on Sheppard Platform when the first quake hit.  We saw it all from up there - the smoke on the day side and the thousand-mile fires at night.  They gave the order to evacuate the station - I never knew why."
   "Pressure from Moscow," I told him.  "They thought we were doing it."
   "Sure.  Everybody panicked.  I guess we did, too.  Our shuttle made a bad landing west of Havana.  I was one of three survivors.  Spent a few days at Key West; then they flew me in to Washington.  Hell of a sight.  Ruins, fires, the Potomac out of its banks, meandering across Pennsylvania, the Washington Monument sticking up out of twenty feet of water, the capitol dome down, a baby volcano building up where Mount Vernon used to be - "

From The Shadow of Heaven (1969):

...In 1992, almost a century ago, World War III had come and gone, and none of the theoreticians had been able to predict what form it would take.  It had always been assumed that the Big War would annihilate most of the population and turn the major countries into vast uninhabited areas similar to what they had been in pre-history.  That had been the first misconception.  Humanity had survived practically unscathed - the only real casualty had been the land itself.

The second mistake had been in the assumption that - if war came - America, Russia and China would fight it out among themselves in one or another of the few simple permutations possible.  In the real event, America, Russia, and China had found themselves on the same side; and they never did find out for certain who the opposition was.  The enemy had assembled his forces, struck, and retired to safety before any of the Big Three discovered the war had started.

The first indication had come when the soil began to die...

...The cloud of anti-neutrinos was first observed crossing the orbit of Jupiter on the third day of January, 1993 - and, because of the extreme difficulty of detecting its existence at all, the astronomers were quite content to use the term 'cloud' in their early reports.  It was not until a month had passed that they dropped the word and inserted in its place the more accurate, though highly emotive, phrase 'rogue planet'...                                   [A Wreath of Stars (1976)]


Later, as she sat in her robe at the kitchen table drinking coffee, her plate of toast and apple-sauce before her, she looked out on the sight of the ditch-rider arriving in his little flat-bottom boat which put-putted up the canal in its official way, never hurrying and yet always arriving on schedule.  This was 1994, the second week in August.  They had waited eleven days, and now they would receive their share of water from the great ditch which passed by their line of houses a mile to the Martian north.   [Martian Time-Slip (1964), p.16]

Australia, population 35 million, is on the threshold of discovering a means of interstellar travel.  Col. Peter Chart, R.A.A.F., takes off in a force-bubble at near-light speed, and is physically recovered but catatonic... 

...Nobody had bargained for the immense expansion that would follow the opening up of Australia to Asian immigrants and the impetus this would give to the development of the inland desert.  Up to 1970 settlement was in most cases confined to a narrow strip of coastline seldom more than one hundred miles wide.  Now, in 1994, there were market gardens in the far west where once a farmer had been lucky to graze two sheep to the acre, and they were well on their way to planting wheat where Lake Eyre had once turned a white mirror of dried salt to the sun.                                                [Takeover Bid (1965)]

Liar! - the episode of Herbie the mind-reading construct [I, Robot (1950)].

From The Ceres Solution (1981):

The single Aristotle space habitat, completed in 2021, had been built in the form of a cone - a shape which provided environments with different gravities.

Among those benefiting from the conical configuration had been medical researchers, who were grateful for the opportunity to study the effect of low-gravity conditions on patients with certain types of cardiac trouble.  They had been given their own facilities in the 0.3G and 0.5G bands on condition that all patients who were fit enough would accept jobs in the zero-gravity production areas...

From Trapped on Titan (1940):

"What's the name of this blob in the cosmos that we're hanging over?" Chadwick asked.

"Titan," Sands replied.  Then he picked up an interplanetary pilot guide, thumbing through it.  "To give it the way the book does," he announced.  "Titan zoned area, one of the satellites of Saturn.  Climatically uninhabitable, this world was deserted in 2021 when its radium deposits were exhausted."

The chubby pilot closed the book and looked at his companion.

"Hell," Chadwick replied sourly...

From the epilogue to The Black Cloud (1957):  On 17 January 2021 "J.B." is left wondering whether to disseminate the code which will allow resumption of communication with the Cloud.

The Second Sleep (2019) quotes a letter of warning - soon borne out by events - sent to a number of high-placed individuals on 22nd March 2022:

...Three months ago I formed, with a group of like-minded colleagues, a working party to consider what contingency measures should be taken to prepare for a systemic collapse of technical civilisation... 

...We regard our society as having reached a level of sophistication that renders it uniquely vulnerable to total collapse.  The gravity of the threat has increased vastly since 2000, with the transfer of so much economic and social activity to cyberspace...


...And Vince would have been in on Maury Frauenzimmer's scheme, put by Maury to Sepp von Lessinger in person at a conference of ersatz engineers in New York in 2023, to make use of von Lessinger's time travel experiments to send a psychiatrist back to 1925 to cure Führer Hitler of his paranoia...

The Simulacra (1964), p.44


The generally accepted reality of AD 2024 was one which contained and also was bounded by things like energy crises, the third world war which seemed both inevitable and imminent, attritive strikes, terrorism, failing resources, social decay, famine, and advertising campaigns for children's knife-proof undergarments...

The Ceres Solution (1981).p.33


From chapter 1 of The Moon Maid (1923), describing the launch of the first spaceship to attempt to reach Mars from Earth:

Our estates were taken under trusteeship by the government.  Our farewells were made at an elaborate ball at the White House on December 24, 2025, and on Christmas Day we rose from the landing stage at which The Barsoom had been moored, and amid the blare of bands and the shouting of thousands of our fellow-countrymen we arose majestically into the blue. 

The main part of the action of The Ceres Solution (1981) takes place in 2025.

...She breakfasted early and spent an hour conscientiously absorbing TV newscasts, with special emphasis on her part of the United States and how its inhabitants were responding to their physical, political and cultural environment in the year AD 2025.  The international news was no worse than usual - the smallpox outbreak in the Netherlands was being brought under control; Sarawak had tested a second fusion device in spite of protests from neighbouring countries; preliminary reports were coming in of some kind of major mishap on the Aristotle space colony; and Britain had introduced sugar rationing for a trial period of three months.  In the U.S.A. the steel, coal and dock strikes were close to being settled, but there had been setbacks in the negotiations on the power workers' and the hospital staffs' pay claims; California police had discovered a partially-completed high-megaton bomb in an underground cavern close to the centre of the Palmdale bulge; in Flint, Michigan, the owner of a sporting goods store had killed his wife by tying her to a chair and hurling a total of 381 darts at her.  And in the Annapolis area, because of a westerly wind, temperatures were comparatively high and the radiation count comparatively low.

Gretana took in the news with the practised indifference which preserved her sanity...

A secret society which aims to change past history, so as to prevent World War One, makes use of a predicted temporal anomaly, described in one of Sir Isaac Newton's secret papers, which allows a person at a specified location in Constantinople to be sent back from 2025 to 1914...

...In the early hours of the morning of 31 May 2025, Hugh Stanton left Trinity College Cambridge in a small motorcade which he was surprised to see was travelling with a police escort.  The Companions of Chronos might have been past their prime but they clearly still counted some pretty influential people among their members.

"Best to be safe," McCluskey said.  "Imagine, Isaac Newton arranges a time-precise rendezvous with history across a distance of three hundred years and we miss it because we're stuck in traffic..."

Theft of the Earth:

A great year:  The year of the first landings on the Runaway Planet that had come blundering into the solar system.  Maybe those landings were a mistake - although they were a very great triumph, too; but maybe if it hadn't been for the landings, the Runaway Planet might have run right through the ecliptic and away. 

However, the triumphal mistake was made, and that was the first time a human eye saw a Pyramid.

Shortly after - though not before a radio message was sent - that human winked out forever...  The next thing that happened... astronomers all over the Earth reported and confirmed the astonishing fact that our planet was on the move...   [Wolfbane (1959)]

   "But you are Eddie Rayner.  I've known you for many years."
   Macklin sighed.  "This may be Eddie Rayner's body," he explained patiently, "but I'm someone else.  You must believe me."

...And then in the year 2050 the blow fell.  Lieutenant-Commander Orthis, after twenty-four years upon the moon, returned to Earth with one hundred thousand Kalkars and a thousand Va-gas.  In a thousand great ships they came bearing arms and ammunition and strange, new engines of destruction fashioned by the brilliant mind of the arch villain of the universe.

...Now, in 2050 A.D., bio-conditioned Earthmen were to be found on ten different worlds of the Solar System - Mercury, Venus, Mars, Jupiter, Io, Europa, Ganymede, Callisto, Saturn and Titan.  Adaptene had burst the former bonds of the narrow range of conditions under which the human body could survive.


...Some twenty thousand colonists lived there.  They were miners, engineers, laborers, technicians in the food and maintenance centers.  There were three doctors, a scattering of teachers and librarians and similar personnel, a handful of police and administrators.  Exactly fifteen people were employed in brewing, distilling, tavern-running, movie operation, and the other non-essential occupations which men required as they did food and air.
   This was New America, chief city of Venus in 2051 A.D....

Though including some drug-induced time-travel, Now Wait For Last Year (1966) is basically set in the year 2055, in the midst of a losing war against Proxima Centauri.  The Terran leader Gino Molinari has made the disastrous mistake of allying with the humans of Alpha Centauri against the chitinous "reegs" of Proxima, though the latter would prefer to make peace on the basis of live-and-let-live - a move which Earth's ruthless and powerful allies are determined to prevent by force if necessary.

...Everything returned.  But totally different.  New. Changed.
   Across from him Don Festenburg leaned back, said, "You're lucky.  But I'd better explain this.  Here.  The calendar."  He pushed a brass object; across the desk Eric saw.  "You've moved slightly over one year ahead."  Eric stared.  Sightlessly.  Ornate inscriptions.  "This is June 17, 2056.  You're one of the happy few the drug affects this way.  Most of them wander off into the past and get bogged down in manufacturing alternate universes; you know, playing God until at last the nerve destruction is too great and they degenerate to random twitches."                                                       [Now Wait For Last Year (1966)]


The Declaration of Megève by the World Council concludes the conference at which the Council abolishes itself, its work successfully completed:
    "The World-State now follows all the subordinate states it swallowed up to extinction; the supreme sovereign government, which conquered and absorbed all minor sovereignties, vanishes from human affairs.  The long, and often blind and misdirected, effort of our race for peace and security has at length succeeded, thanks to this great Council that now retires.  It retires with the applause and gratitude of all mankind.  And now in serenity and security we can survey the property it has redeemed from waste, this planet and its possibilities, our own undeveloped possibilities too, and all the fullness of life that lies before us.  This is the day, this is the hour of sunrise for united manhood.  The Martyrdom of Man is at an end.  From pole to pole now there remains no single human being upon the planet without a fair prospect of self-fulfilment, of hearth, interest and freedom.  There are no slaves any longer; no poor; none doomed by birth to an inferior status; none sentenced to long unhelpful terms of imprisonment; none afflicted in mind or body who are not being helped with all the powers of science and the services of interested and able guardians.  The world is all before us to do with as we will, within the measure of our powers and imaginations.  The struggle for material existence is over.  It has been won.  The need for repressions and disciplines has passed.  The struggle for truth and that indescribable necessity which is beauty begins now, unhampered by any of the imperatives of the lower struggle.  No one now need live less nor be less than his utmost.
   "We must respect the race and each other, but that has been made easy for us by our upbringing...  We must contribute our modicum of work to the satisfaction of the world's needs.  And, for the rest, now we can live..."

   ...Night became day.  He was still in the room at the Caesar Hotel but it was later; he could not tell how much.  Months?  Years?  The room looked the same but probably it always would; it was eternal and static.  He left the room, descended to the lobby, asked for a homeopape at the newsstand next to the reservations desk.  The vendor, a plump old Mexican woman, handed him a Los Angeles daily; he examined it and saw that he had gone ahead ten years.  The date was June 15, 2065...           [Now Wait For Last Year (1966)]

5 October: birth of Leon Cartwright, future Quizmaster of the Nine Planets.

..."You can't operate this," Moore said quietly.  "This isn't your line.  What are you?  I examined the records.  You were born October 5, 2140, outside the Imperial Hill.  You've lived there all your life; this is the first time you've been on this side of the Earth, let alone on another planet.  You had ten years of nominal schooling in the charity department of the Imperial Hill.  You never excelled in anything..."

According to Flight on Titan:

The year 2142, as most people recall, was a disastrous one in the financial world.  It was the year of the collapse of the Planetary Trading Corporation and the year that ushered in the resultant depression.

[The Game Players of Titan (1963)]


Officially, Boss Kellon was merely executive secretary of the Union of Spacemen, Managers and Engineers.  But Boss, now in 2145, was equivalent to Caesar.  From the unitron converters on Mercury to the lonely mining outposts scattered across the Jovian moons, the Union dominated mankind...   [Breakdown (1942)]


The Solarion, in 2146, returning with her seventh cargo of sunstone, was accosted by a strange vessel in space - a slim red arrow of a ship, unlike the mirror spheres of SPC.  Heliographs flashed a message, signed "Redlance", demanding surrender of the ship and cargo, "in the name of liberty and human right."  [The Crucible of Power (1939)]


Report reaches Earth that the Sun Station has been lost [The Crucible of Power (1939)]:

The Solarion III, in 2148, safely reached the Sun and returned.  But her holds were empty and she brought appalling news...

For a treatment of some important events of this mid-22nd-century year see the 1966 film Daleks' Invasion Earth 2150 A.D., based on the 1964 Dr Who serial (in which the invasion occurred in the year 2164 - the figure being later rounded for the film). 

[Note from Zendexor: I never saw the film but I vaguely remember some of the images in the original TV version, though I had forgotten the plot.  According to Wikipedia the Daleks attempt to turn the entire Earth into a spaceship.]


Warning of the approach of an anti-matter world:

It was on January 15, 2156, that the astrophysicist, Dr. James Carter, had the first glimmer of light - literally.  He was working on the new five-hundred-inch reflector of the Mt. McKinley observatory at the time, and noticed a darkening of his photographic plate from the spectrometer focused on Polaris...

Disappearance of Kennicot Muir and founding of the Society of Thieves [The Paradox Men (1953)].


4 August:  Carew, from the Institute, visits Dr Homer Green, the Invariant.  (See 1943.) tread on rugs, to see chairs covered in cloth with a nap, to see instruments for smoking, to see and hear a primitive radio... above all to see an open fire; all this gave me a sense of unreality, prepared though I was.  Green saw by the fire in a chair, as we almost invariably find him, with a dog at his feet.  He is perhaps the most valuable man in the world...

The peacefully seated man expresses confidence that the invariant-treatment will work on him.

"It does work, Dr Green," I assured him.  "Indefinitely."

"We mustn't be premature," he said.  "After all, a short time - "

"Do you recall the date, Dr Green?" I asked.

"September 11th," he said.  "1943, if you want that, too."

"Dr Green, today is August 4, 2170," I told him earnestly.

...For three months now, this Earth-year of 2170, mysterious accidents had been happening to commercial space-ships.  Non-arrival at destination, and then later found by the Interplanetary Patrol, derelicts in space.  Gruesome damn' thing.  A ship unharmed, save that its air was gone...    [Phantom of the Seven Stars (1940)]


from POWER UNLIMITED by Martin Brand, Solar City, Earth, 2171, regarding contra-terrene matter:

...Undismayed by the untouchable stuff, the space engineers have named it familiarly seetee, and they are reaching daringly to grasp it now.  The mightiest force yet known, it can create a new kind of freedom - the freedom of power.  Or, misused, it can crush every human freedom.  That is the problem and the promise all our planets face today.

Seetee Shock (1949, 1950)


The time-retracing Toynbee Twenty-Two crash-lands in the Ohio River near Wheeling on 21st July, five years before its launch.

Spoken in 2177:

"...Four years ago the Lunar Station began sending me microfilm plates of both celestial hemispheres by the space second.  One of these plates is of particular interest, and I feel that what it shows may have a bearing on the future of civilization.  It should be analysed immediately."   [The Paradox Men (1953)]


28th April:  Will Carewe, believing that he has just taken an immortality drug, reflects...

...Could it be that there would come a day, perhaps only a hundred years in the future, on which he would have to check his diary to remember the colour of Athene's hair?  Without absolute continuance of the personality was there such a thing as immortality?  Or did it simply mean that his deathless body would be inhabited by a series of strangers, each fading imperceptibly into the next as the biological slates were wiped clean?

"An asteroid a couple of miles in diameter, mainly ice.  The Belt telescopes spotted it fairly early, in... 2183, I think.  It was still outside Jupiter's orbit.  Mahmed was the first man to land on it.  He was also the man who plotted its orbit and found out that it was going to hit Mars."

First visit to Erebus Valley, Mercury [Where the Nightlife Never Ends].

From Indoctrinaire (1970, 1979):
"...if you can imagine a place existing at two different times, then that is this.  Where we are now is the Planalto of AD 2189.  Where we were somewhere over there," he waved vaguely with his hand, "was in 1989."

Beginning of the Venusian invasion and disastrous "Venusoforming" described in The Metamorphosis of Earth (1951).

Marcius Kemble, Dictator of Mars, is exiled to Pluto.  [Escape from Pluto (1947)]


The events of Solar Lottery.  To quote the blurb:

"Positions of public power decided by a sophisticated lottery.  Everyone had a chance, could live in hope.  Opium for the people.  One day you too could be boss.  And with it: The Assassination Game, which you could watch on TV.  Would the new man be good enough to avoid his chosen killer?  Survival of the fittest formalised into a game.  Lots of excitement for everyone, keeps them all happily distracted while the Big Five industrial complexes run the world, the solar system, the people, unremarked, unopposed. 

Then in the year 2203 a hitch developed in the system."


...He took out a much-folded paper, opened it with shaking hands, handed it across to Vallant.  It was a map, creased and patched, grimy and oil-splattered.  The legend in the corner read:

   March 2212

The old man leaned, pointing.  "See this spot right here?  A river cuts through the mountains - a river of liquid nitrogen.  The gorge is a thousand feet deep - and the falls come thundering down out of the sky like the end of the world.  That's the place, Ame.  They'd kill to get it..."

"Sort of a shame.  Romantic, kind of.  I mean, leaving just one graveyard untouched during all these centuries.  The other graveyards were cleaned out, what year was it, Jim?"

"About 2260, I think.  Yeah, that was it, 2260, almost a hundred years ago.  But some Salem Committee they got on their high horse and they said, "Look here, let's have just ONE graveyard left, to remind us of the customs of the barbarians..."

[Pillar of Fire (1948)]


Mace Waldron, the famous pilot who saved that Martian liner in 2263...  [Jay Score (1941)]


Jay Score's piloting rescues the Upskadaska City.

You may remember the stunt that the audiopress of 2270 boosted as "McNulty's Miracle Move"?  It's practically a legend of the spaceways.  Afterward, when we'd got safely home, McNulty disclaimed the credit and put it where it rightfully belonged.  The audiopress had a good excuse, as usual.  They said he was the captain, wasn't he?  And his name made the headline alliterative, didn't it?  Seems that there must be a sect of audio-journalists who have to be alliterative to gain salvation.  [Jay Score (1941)]


Colonization of Erebus Valley, Mercury [Where the Nightlife Never Ends].


Disappearance of Orbitsville, the Dyson sphere which had absorbed Earth's attention for two centuries; beginning of a Renaissance on Earth.  [Orbitsville Departure (1983)]

15 February:  Ben Reich, megalomaniac boss of Monarch Utilities, having wakened screaming from his recurrent dream of The Man With No Face, comes to a decision: he will murder his arch-rival Craye D'Courtney of the D'Courtney Cartel.

It's D'Courtney who's giving me the screams.  Not because I'm afraid of him.  I'm afraid of myself.  Known all along.  Known it deep down inside.  Knowing that once I faced it I'd have to kill that D'Courtney bastard.  It's no face because it's the face of murder...   [The Demolished Man (1953), p9]


...It was a diamond-clear morning - one of a seemingly endless succession of fine mornings in that summer - yet he was a acutely conscious of the date as he moved about the familiar environment of the kitchen.  August 25, 2302.  Only nine years had passed since Orbitsville had departed for another universe, but it had been two whole centuries since an exploration ship had slipped away from the Earth-Moon system heading for unknown space.  Now the Columbus was fully stored and ready to spiral out of Polar Band One to test itself against sun-seeded infinities, and the date would be one for the history books...

16 September:  Gully Foyle, spaceman, marooned on the wreck of the merchant ship Nomad, sees the approach of what he trusts is a rescue ship.  But the ship, Vorga, passes him by, leaving him to his fate.  This act galvanizes the hitherto dull-witted, unambitious Foyle:

...the stereotype Common Man was no more.  The key turned in the lock of his soul and the door was opened.  What emerged expunged the Common Man for ever.

"You pass me by," he said with slowly mounting fury.  "You leave me rot like dog.  You leave me die, Vorga...  No.  I get out of here, me.  I follow you, VorgaI find you, Vorga.  I pay you back, me.  I rot you.  I kill you, Vorga.  I kill you deadly."

The acid of fury ran through him, eating away the brute patience and sluggishness that had made a cipher of Gully Foyle, precipitating a chain of reactions that would make an infernal machine of Gully Foyle...     [The Stars My Destination (1955), p21]


September: kidnap of Roy Truesdale by the protective Brennan-monster who lurks on the borders of the Solar System [Protector (1973)].


Elroy did not twitch when acrid smoke curled up from the message spool.  He had half expected that.  In any case he had recognized the voice.  His own.  He must have made this tape for... Vandervecken... during the time he couldn't remember.

He spoke to the blackened tape.  "You wouldn't lie to yourself, would you, Roy?"

Under what circumstances?

He got out of the car and walked to the Tourist Office and bought a morning newstape.  His set still worked, though the message spool was a charred lump.  He played the tape for the date.  January 9, 2341...

...The print in the old books had faded centuries ago though much of the lettering was still visible - if there had been any to read it.  But many generations had passed since anyone had had a use for a set of seven-figure logarithms, an atlas of the world, and the score of Sibelius' Seventh Symphony, printed, according to the flyleaf, by H.K.Chu and Sons, at the City of Pekin in the year 2371 A.D.                          [History Lesson (1949)]


...The largest recorded crowd ever was of an estimated two hundred and ten million people who assembled for the event of the Joyous Declaration of the World God Uhuru movement on the Central African plain in A.D. 2381, this number being compressed into a remarkably small area thanks to the ingenious open-plan multi-storey stadia erected for the occasion...

"...It is in our generation that perfection has been reached, and we want the distinction of having reached it.  Your animals are in the way."

Cranwitz shook his head stubbornly.  "They take up so little room; consume so little energy.  If all were wiped out, you might have room for what?  For twenty-five more human beings?  Twenty-five in fifteen trillion?"

Bunting said, "Twenty-five human beings represent another seventy-five pounds of human brain.  With what measure can you evaluate seventy-five pounds of human brain?"

"But you already have billions of tons of it."

"I know," said Alvarez, "but the different between perfection and not-quite-perfection is that between life and not-quite-life.  We are so close now.  All Earth is prepared to celebrate this year of 2430 A.D.  This is the year when the computer tells us that the planet is full at last..."

[2430 A.D. (1970)]


Yawning, Mr. Eric Stokes-Harding stood before the great open window, staring out.  Below him was a wide, park-like space, green with emerald lawns, and bright with flowering plants.  Two hundred yards across it rose an immense pyramidal building - an artistic structure, gleaming with white marble and bright metal, striped with the verdure of terraced roof-gardens, its slender peak rising to help support the gray, steel-ribbed glass roof above.  Beyond, the park stretched away in illimitable vistas, broken with the graceful columned buildings that held up the great glass roof.

Above the glass, over this New York of 2432 A.D., a freezing blizzard was sweeping.  But small concern was that to the lightly clad man at the window, who was inhaling deeply the fragrant air from the plants below - air kept, winter and summer, exactly at 20 degrees C...                   [The Cosmic Express (1930)]

Expedition of the spaceship Goddard to Pluto [Expedition to Pluto (1939)].


The narrator of L'An 2440 (1771) wakes up in Paris in this year and finds himself in a pacifist, egalitarian utopia under a constitutional monarchy.


...All old Dr Full knew was that she was peering at the neck of the forceps and then turned white.  Very carefully, she placed the half of the forceps back in its loop of cloth and then replaced the retractor and the speculum.  "Well?" he asked.  "What did you see?"

"'Made in U.S.A.,'" she quoted hoarsely.  "'Patent applied for July 2450'."

The first independence movements among the colonized planets started in 2470 [The Three Planeteers (1940)].


The first difficulty was with language.
   That is only to be expected when you jump five hundred years; but it is none the less perplexing to have your first casual query of: "What city is this?" answered by the sentence: "Stappers will get you.  Or be you Slanduch?"

End of the 2481-90 War...

...brought to an end by a militant organization of women who, first of all, refused to bear any more children, then deserted the munitions factories, causing both sides to withdraw great numbers of men to replace them, and, finally, took up arms and assassinated the individuals whom they considered to be the key men of the war.  The conflict was the direct cause of the world matriarchy that held sway for the next three thousand years...     [Seeker of Tomorrow (1937)]

"Chris Barton, war correspondent for Interplanetary Press, the Sexton Syndicate. Wherever he goes, it means trouble."

Chris Barton smiled—bird of ill-omen, vulture of pain. Beyond the dome of pearly glass, on the other side of Venus, lay the swamp where he had left his boyish illusions, covering the Leng campaigns. Out beyond the steamy canopy of clouds was Mars, where he had stood by a tele-transmitter until it was blown up under him, covering the Martian World War of 2504...

hatching out embryos: any cow could do that.
“We also predestine and condition. We decant our babies as socialized human

The little boy looked with awe at the scene, then turned his face upward, demanding, "What are we going to do when this hole gets so big that it takes up the whole world?"

We laughed...                                                    [The Dwindling Sphere (1940)]

The great and powerful League of Cold Worlds had been formed by Jupiter, Saturn, Uranus and Neptune, under a ruthless, ambitious dictator. Feeling themselves menaced, Mercury, Venus, Earth and Mars had formed the Inner Alliance. The Alliance had sent out many spies to gain information of the League's threatening plans, but nearly all of them had rapidly been detected and executed.
   Then John Thorn, captain in the Earth Navy, had conceived his patriotic plan. He and two friends, Sual Av, Venusian engineer, and Gunner Welk, Mercurian adventurer, would go forth into the underworld of the system as outlaws...             [The Three Planeteers (1940)]

Sudden raw materials shortage -

...Green’s fingers riffled the sheaf of teletyped flimsies.
“This is what I’ve got to tell you. Here are the latest reports from our
mines in the Andes and from the Moon. We’re faced with a drastic raw
materials shortage. Our supply of Uradonite is giving out.”
Uradonite. Nobody had to tell Chick Evans and me what that would mean.
The whole space-flying industry was dependent upon the volatile-active
element Z-470. Nullo-grav units had made vessels weightless. But that
could not provide propulsion. Then came the Mansfield cyclotronic
engine, a power unit by which the immensely heavy atoms of Z-470 were
broken down into electronic streams, the rocket-streams by which all
space-flyers are propelled...

An expedition is therefore quite rightly sent to Neptune...  [The Wings of Icarus (1943)]

The Martians suddenly threaten Earth with a "Photo-Atomic Ray", which makes it imperative to send an expedition to Saturn in search of a substance called "tridium" which may neutralise the Ray.

...The Earth, in this year of grace 3057, was a wonderful place to live in, and Copia was the political and cultural center of the Earth.  For nine hundred years now, the peoples of the Earth had lived at peace with one another as members of a single integrated community...  No longer did region war against region, or group against group, or class against class...

The oddity of an ageing G4 yellow moving about a common axis with a white supergiant no more than eleven million years old had already engaged the interest of the cosmologists attached to the Chinese / American fleet.  The spectroanalysis spurred them into active investigation.

The supposedly Earth-like planet of the distant binary system was filed under the appellation G4PBx/4582-4-3.  Symbols were despatched on their lengthy journey through the dust clouds to Earth.

Berthed inside the flagship of the fleet, then cruising the outer fringes of the Ophiuchus dust clouds, was an automated colonizing ship.  The ship was programmed and despatched to G4PBx/4582-4-3.  The year was 3415.                                                                              [Helliconia Winter (1985)]

The "Fostering of Ooranye" - when the inhabited Uranus of Uranian Gleams (2015) surfaces in this continuum.  The Fostering is defined as

the one successful example in history of "reality engineering"; the action taken, and the process which took place, on 10th July A.D.3564, by which the gas giant planet Uranus became, and now always has been, more fully itself as the ice-giant planet Ooranye.  By analogy the Fostering has been likened to the switching of points on a railway after a train has gone past: so that, if the train were to go into reverse, it would go back along a different track.  In other words, a "new" past was grafted onto Uranus...  Meanwhile the un-Fostered reality survives in one remaining clue: the "U" in the adjective "Uranian".

Note: the Fostering appears to have happened at two different dates; see 4160.  Such an event can hardly have two stages; so either there is an inconsistency, or we may take it that cause-and-effect from the 4160 event cascaded backwards and triggered the 3564 event.  I reckon the latter is right; it's what the Earth historian seems to be saying.


When Earth's colonizing starship entered the Freyr-Batalix system in 3600 A.D., it established a base on Aganip, the inner planet closest to Helliconia.  On Aganip, 512 colonists were landed.  They had been hatched aboard the starship during the final years of its voyage...

The historian says:

Everybody knows the bare outline of the events which ushered in our present era; how the Second Great Fleet did succeed in reaching Arclour and its ultimate sivvan, and how that discovery retro-triggered our retro-Fostering of Ooranye, that is to say, the grafting of Ooranye's true history onto the history of our solar system.

4901 was in 4901 that nuclear war broke out between the planets... after a statesman on Earth made the mistake of using the old derogatory term "immigrants" about the inhabitants of Mars...  Mars was silenced for ever...  Earth was hit by no more than twelve 10,000 megaton bombs.  It was enough...  [Helliconia Winter (1985)]

...The Year 5000.  He had become one of the Kotolies.  The Kotolies, a strange, shy little animal native to Mercury, had been brought back to Earth in the fortieth century and crossbred with dogs.  The new hybrid, a domesticated pet, could speak and think the language of Earth, while still retaining the lore of Mercury.

English had long formed the universal speech, but the white and coloured races had both disappeared...  A blend, a merging, an amalgamation of the old stocks, the world-wide type now stood nearly seven feet tall, deeply golden of skin, richly varied in the coloration of hair and eyes...     [Finality Unlimited (1936)]

From The Man Who Awoke (1933):

"...Do you pretend to come from that shameful scene?"

"That is precisely the sort of thing we used to do," replied Winters, "although we did not call it by the same set of names."  He could barely repress his elation.  There could no longer be the slightest doubt of it - he was alive in the year 5000!  His clock had been accurate!

"According to the revision of the year 7990," said the robot, "arrived at by convention, any male human under the age of one hundred, sound in mind and body, and unhampered by religious bonds or belief, which are subject to a court of inquiry, must fight a duel whenever challenged."  [p.28]

...War, the man had said.  A war in time...

It would load the personnel of the Justice Department of the year 7990 with spies and fifth columnists and saboteurs.  And it would do that thing so cleverly one could never find the spies.

But, as in an ordinary, honest war, there would be strategic points.  As in chess, there would be one key square.

Sutton was that square...    [p.126-7]

   ...In 8054 A.D. history repeated itself - as it always does.  The First Galactic Empire was greaking up.  Dictators, Emperors, Consolidators wrested the rulership of their own or kindred solar systems from Central Control.  Space pirates raised flags and recruited fleets to gorge on spoil plundered from this wreckage.  It was a time in which only the ruthless could flourish...                                                                                                                          [The Last Planet (1953)]

"Tell me," said Dean.  "Now that you're here, what do you plan to do?"

"Easy," said Sutton.  "You're going to talk to me.  You're going to tell me something I need to know."

"Gladly," Dean agreed.

"You said you came from the eighty-fourth.  What year?"

"Eighty-three eighty-six," said Dean.  "But if I were you, I'd go up a little ways.  You'd find more to interest you."

"But you figure I'll never get even so far as that," said Sutton...

Lord Clane Linn's archaeological researches on Venus...

...His own estimate of the time that had gone by since the great war was of the order of 8,000 years.  He had enough data from other pits concerning the calendar system of the ancients to guess that by their reckoning, present-day Linn was existing in 12,000 A.D.     [Empire of the Atom (1956)]

12,455 the year 12,455, a group of star-systems near Polaris complained that Earth was too remote to appreciate their problems, and they set up an independent kingdom [The Star Kings (1949)].


...That golden shape on the golden steps shook and fluttered like a bird gone mad - like a bird imbued with an intellect and a soul, and, nevertheless, driven mad by ecstasies and terrors beyond human understanding.  A thousand worlds watched. 

Had the ancient calendar continued, this would have been A.D. 13,582.  After defeat, after disappointment, after ruin and reconstruction, mankind had leaped among the stars.

Out of the shock of meeting inhuman art, of confronting non-human dances, mankind had made a superb esthetic effort and had leaped upon the stage of all the worlds.

The golden steps reeled.  Some eyes that watched had retinas.  Some had crystalline cones.  Yet all eyes were fixed upon the golden shape which interpreted "The Glory and Affirmation of Man" in the Inter-World Dance Festival of what might have been A.D. 13,582....

15,862 only made matters worse when someone in the computing section worked out the future history of our errant freighter.  You see, nothing is ever really lost in space.  Once you've calculated its orbit, you know where it is until the end of eternity.  As we watched our lounge, our library, our games, our mail receding to the far horizons of the solar system, we knew that it would all come back one day, in perfect condition.  If we have a ship standing by it will be easy to intercept it the second time it comes round the sun - quite early in the spring of the year A.D. 15,862.    [Special Delivery (1957)]

"June 5th, 1939," I replied, feebly.  The creature went through some contortions, sorted a few metal tubes with its hands, and then announced in its metallic voice:

"Computed in terms of your method of reckoning, I have travelled back through time exactly twenty-eight thousand years, nine months, three weeks, two days, seven hours, and a certain number of minutes and seconds which it is useless for me to enumerate exactly."


From Seeker of Tomorrow (1937), regarding the cataclysmic events of 33,885 A.D:

...The Invader, we were informed, was a planet about twice the size of Jupiter, which had come through interstellar space, cleaved a path through the solar system and vanished into the cosmos.  It passed between the orbits of Mars and the asteroid belt, its influence upsetting the normal balance of half the system, making the paths of the asteroids, Mars and Earth much more eccentric, capturing and taking with it two members of the Trojans group of asteroids... 


From Seeker of Tomorrow (1937):

'...I rubbed my eyes and looked again.  Standing beside the bed, his face expressive of kindly solicitude, was a bald-headed man garbed in rompers of brilliant hue....

'"You are within my house situated in the city of Leamore," he answered in a pleasantly modulated voice, "and the year is 772 by the new reckoning, or 34656 by the old.  You have leaped a chasm of time representing about thirty-two thousand years!"

The year the Time Traveller emerged into a far-future England divided between the Eloi and the Morlocks - as narrated in The Time Machine (1895).


...The solar system had altered profoundly.  The tidal drag had brought the moon and Earth together millions of years before, with a collision that made them fuse, flame, and create a new star.  The star circled around the old, dying sun which, as it cooled and solidified under the light of the new star, developed its first species of life-forms, simple forms radically different from the beginnings upon the former planet Earth.  Pluto had been torn away from the system by a wandering star.

He was a nitrogenised metallic spore, clinging to the peak of a jagged, titanic range of mountains fifty miles high, composed of volcanic magma, and overhanging an acid sea.  He was the life primeval, from which in billions of years of later time would arise the deathless, indestructible, purely intellectual and mathematical metallic beings who would shape the destiny of the cosmos for the inheritance of still more complex life-forms of still later trillions of years of ultra-time...   [Finality Unlimited (1936)]
