We were robbed. By this point in time, we were supposed to have giant wheel-shaped space stations, huge lunar bases in crater Clavius, and expeditions to Saturn. Instead we have a few footprints on the moon, a few kilos of lunar rock, an aging smallish space station nearing the end of its operational life, and no space shuttles. And there has not been a man on the moon since 1972. If only things had turned out a little differently.
Which leads us to the ever-popular "Alternate History" branch of science fiction. Here SF authors make small but significant changes to the flow of history, and predict the results. Some are not quite as nice places to live, some are better, but all are very different from the history we are currently living in.
As far as spacecraft based alternate history goes, most alter some point a few decades back. Exceptions include James White's THE SILENT STARS GO BY, where Hero of Alexandria's aeolipile survives the sack of Rome, resulting in the first starship being launched in 1492.
WARNING! SPOILERS!In his Hugo Award nominated short story "The Return of William Proxmire", Larry Niven writes of Proxmire funding the development of a time machine. Proxmire's evil plan is a desperate attempt to destroy the literary genre of "science fiction" altogether. Proxmire notes that his efforts to abolish space travel are opposed by people who grew up reading science fiction in general, and the works of Robert Heinlein in particular. In our time line, Heinlein was in the US Navy but was discharged in 1934 due to pulmonary tuberculosis. Proxmire travels back in time and inject Heinlein with antibiotics, ensuring that Heinlein will stay in the Navy and not become an author. Proxmire returns to the present, snickering that he has destroyed science fiction and space travel.
Boy, is he disappointed! When he returns, Dr. Andrew Minsky tells Proxmire the bad news.
The man who goes by the name Grimjier of Hobby FuZion is working on a tabletop game played with little plastic spaceships called "Legend of Sol: Torch War". This is set in an alternate history where the North American Space Command and the Supreme Soviet Cosmo forces battle in space in the far flung future year 1960. The early American ships are based on the Boeing X-20 DynaSoar and Project Gemini. The battleships are nuclear pulse Orion drive.
The plastic miniatures can be purchased from his Shapeways on-line store. I recommend that you order them in the "Transparent Detail" material, the "White Strong & Flexible" has a grainy look. Once you paint the transparent detail it will be a nice crisp (opaque) model.
The actual game is still under development. You can follow recent developments by monitoring the "Hobby Fuzion Minatures" thread on the Starship Combat News forum.
Man Conquers Space is an awesome movie project set in an alternate history where the Collier's Magazine "Man Will Conquer Space Soon!" predictions actually came to pass. It has it all, the giant winged ferry rocket, the wheel shaped space ship, the lunar expedition of tank ships; they are all there. Just like a Chestley Bonestell painting.
Deep Cold has images from an alternate history where the Cold War between the US and the Soviet Union extended into space. All the rendered images are based on historical fact. All the spacecraft shown were planned but never flew operationally (some cancelled before they left the drawing board). They represent a fascinating look at what might have been.
Rob Davidoff has a degree in Mechanical Engineering with a concentration in Aerospace. In other words, he is a rocket scientist. Currently he is printing turbines for GE Power. Ian Mitchell is a physics Ph.D. student at the University of Houston studying experimental particle physics. Together they are currently working on a fascinating alternate history of the NASA space flight program called Eyes Turned Skyward. It diverges from our history at the point where the Apollo program comes to an end, and in our time line NASA decides to go with developing a space station, instead of the Space Shuttle. The consequences of not having a reusable launch vehicle in the 1970's are interesting, to say the least.
David Portree is the manager of the Regional Planetary Information Facility, Astrogeology Science Center, US Geological Survey. His blog DSFP's Spaceflight History Blog is full of great articles on the history of spaceflight. But recently he has been applying his encyclopedic knowledge to crafting an alternate history that he calls "Imagining Another Apollo". Last I checked it was up to part 5, it is interesting reading.
The Ministry of Space is a graphic novel written by the legendary Warren Ellis and illustrated by Chris Weston, published in 2001. It is an interesting alternate history where at the end of World War II the British instead of the Americans got their hands on Germany's rocket scientists. This results in a new British empire in Space. But it is all very scientifically accurate, abet very Collier's flavored.
Chris Weston's amazing British-Colliers-von Braun rockets are a real treat for the eye. Warren Ellis story is believable, plausible, but mordant and containing cutting social commentary. And there are some who wonder if Britain can create a real Ministry of Space.
Voyage by Stephen Baxter is an alternate history novel where president John F. Kennedy was wounded but not killed in the assasination attempt in 1963. It traces the history of a vastly expanded space program, though it does include a disasterous manned test flight of a NERVA spacecraft that puts a stop to nuclear power in space. "Boo, hiss" says the author of the Atomic Rocket website. But the rest of the novel is fascinating reading.
Titan by Stephen Baxter is an alternate history novel where a strong tide of anti-intellectualism in the United States (led by a fundamentalist president who mandates that school science classes should give equal teaching to the theory that the Sun orbits around the Earth) threatens the existence of NASA. NASA is forcibly merged with the US military, so its budget can be diverted into increasing defense spending. After the permanent shutdown of the space program, a small team of NASA scientists hatch a desperate plan to rekindle pubic interest in manned space exploration and combat the loss of the pioneering spirit in modern US politics and culture. They create a manned expedition to the moon Titan by recycling older spacecraft into new uses. Their mission is sabotaged at all levels, but it takes new urgency when a Chinese military stunt involving an Earth impacting asteroid goes terribly wrong.
