I'm talking about like the space shuttles and missions and things like that.. i have a test on all of it tomorrow and i dont understand the difference. were those all missions? and then like the Challenger, Columbia, Endeavor and those were just shuttles? what's the difference between those and the Mercury, Gemini, and Apollo things?
What is the difference between Mercury, Gemini, Apollo, and space shuttles?
