Marooned

 The film based on the novel was released in 1969, four months after the Apollo 11 mission.
The first edition of the novel Marooned involved a single astronaut
stranded in orbit in a Mercury spacecraft, a rescue mission launched
using the then-experimental Gemini spacecraft, and a Soviet Vostok also
becoming involved in the mission.

The 1969 re-release
of the novel, which coincided with the film, was extensively rewritten
to reflect the advancements in the U.S. space program. The plot featured
three U.S. astronauts stranded in an Apollo spacecraft after separation
from an Apollo Applications Program space station very similar to the
later Skylab program missions flown in 1973-74.
The rescue mission
in the 1969 edition was flown with a Titan III-C rocket carrying an
experimental X-RV lifting body spacecraft, which was never actually
flown in space. In this edition, the Soviet involvement in the rescue
mission was portrayed as using a Soyuz spacecraft. Caidin chose "Soyuz
11" as the designation of the rescue flight. In 1971, Soyuz 11 mission
ended in tragedy when all three cosmonauts perished during re-entry
while returning from Salyut 1, the first manned space station.
In the original edition, the Mercury astronaut is Dick Pruett, and the pilot of the rescue mission is Jim Dougherty. In
the 1969 version, the names are changed to Jim Pruett and Ted
Dougherty, with Clayton "Stoney" Stone and "Buzz" Lloyd added to make up
the three-man Apollo crew.
