What is Voyage about?
Kennedy survives Dallas (wheelchair-bound, a voice rather than a president), and his 1969 phone call to the Apollo 11 astronauts commits America to Mars. Baxter then does something braver than triumphalism: he prices it. The Ares programme cannibalises the shuttle, the probes, the space stations — the entire robotic golden age — and costs lives in a hauntingly plausible pad disaster, before geologist Natalie York, the mission's conscience, finally reads Martian stone with human eyes. Written by an engineer who applied to be a cosmonaut, it is the definitive what-if of the space age: wish granted, invoice attached.
Why it matters
Sidewise Award winner for alternate history; NASA-procedural SF's high-water mark, dramatised by the BBC and visibly ancestral to For All Mankind.
