Apollo Quartet Series by Ian Sales

A nuclear war has killed everyone on Earth, leaving stranded on the Moon nine astronauts at Falcon Base. With them they have a "torsion field generator", a mysterious device which they hope will find them an alternate Earth which has not succumbed to nuclear armageddon. But once they've found such an Earth, how will they make the trip home? They have one Lunar Module, and that can only carry four astronauts to lunar orbit...

For fifteen years, Earth has had a scientific station on an exoplanet orbiting Gliese 876. It is humanity’s only presence outside the Solar System. But a new and powerful telescope at L5 can detect no evidence of Phaeton Base, even though it should be able to. So the US has sent Brigadier Colonel Bradley Elliott, USAF, to investigate. Twenty years before, Elliott was the first, and to date only, man to land on the Martian surface... moreFor fifteen years, Earth has had a scientific station on an exoplanet orbiting Gliese 876.

What he discovered there gave the US the stars, but it might also be responsible for the disappearance of Phaeton Base… less

It is April 1962. The Korean War has escalated and the US is struggling to keep the Russians and Chinese north of the 38th parallel. All the men are away fighting, but that doesn’t mean the Space Race is lost. NASA decides to look elsewhere for its astronauts: the thirteen women pilots who passed the same tests as the original male candidates... moreIt is April 1962. The Korean War has escalated and the US is struggling to keep the Russians and Chinese north of the 38th parallel. All the men are away fighting, but that doesn’t mean the Space Race is lost. NASA decides to look elsewhere for its astronauts: the thirteen women pilots who passed the same tests as the original male candidates. These are the Mercury 13: Jerrie Cobb, Janey Hart, Myrtle Cagle, Jerri Sloan, Jan Dietrich, Marion Dietrich, Bernice Steadman, Wally Funk, Sarah Gorelick, Gene Nora Stumbough, Jean Hixson, Rhea Hurrle and Irene Leverton. One of these women will be the first American in space. Another will be the first American to spacewalk. Perhaps one will even be the first human being to walk on the Moon.Beneath the surface of the Atlantic Ocean, deep in the Puerto Rico Trench north of San Juan, lies a film bucket from a KH-4 Corona spy satellite. It should have been caught in mid-air by a C-130 from the 6549th Test Group. That didn’t happen. So the US Navy bathyscaphe Trieste II must descend twenty thousand feet to retrieve the bucket, down where light has never reached and the pressure is four tons per square inch. But there is more in the depths than anyone had expected, much more.This is not our world. But it very nearly was. less

It is 1965 and Ginny Eckhardt is a science fiction writer. She’s been published in the big science fiction magazines and is friends with many of the popular science fiction authors of the day. Her husband, Walden, has just been selected by NASA as one of the New Nineteen Apollo astronauts… which means Ginny will be a member of the Astronaut Wives Club. Although the realities of spaceflight fascinate Ginny, her genders bars her from the United State space programme... moreIt is 1965 and Ginny Eckhardt is a science fiction writer. She’s been published in the big science fiction magazines and is friends with many of the popular science fiction authors of the day. Her husband, Walden, has just been selected by NASA as one of the New Nineteen Apollo astronauts… which means Ginny will be a member of the Astronaut Wives Club. Although the realities of spaceflight fascinate Ginny, her genders bars her from the United State space programme. Her science fiction offers little in the way of consolation—but perhaps there is something she can do about that… Covering the years 1965 to 1972, when Walden Eckhardt lifts-off aboard Apollo 15 as the mission’s lunar module pilot, this is Ginny’s life: wife, science fiction writer, astronaut wife… because that is ALL THAT OUTER SPACE ALLOWS. less
