How did Apollo 2 get off the moon? Doesn't rocket fuel require oxygen to work?
Question Date: 2015-03-05
Answer 1:

Apollo 2 never launched. Apollo 7 was the first Apollo mission to launch, and Apollo 11 was the first to actually land on the moon.

The Apollo spacecraft carried their oxygen with them, which is how they were able to fire their rockets while in space. Spacecraft today also must do this as well, even for relatively innocuous maneuvering such as the Russian personnel vehicles that dock with the international space station today.
