6、t of Program Mercury were designed simply to discover if humans could actually survive a round-trip voyage into space.

8、llo Project. The initial idea was to get a human close to the Moon, but not actually on it. There were too many unknowns about the surface of the Moon to plan a safe landing.

13、ead of sending a person to space and back again, which required only one lift-off from Earth followed by a landing, the Apollo Project now entailed an Earth lift-off, followed by a landing on the Moon, another lift-off, and then a final Earth landing. The Gemini Program, therefore, was created to co

It took eight years and numerous attemp
