Earth and Moon Missions and Satellites

Gemini | Apollo | Hubble Space Telescope

Here you can learn about two of the most important space programs in U.S. history: Gemini and Apollo. Gemini was the first U.S. program where an American completed a space walk, and Apollo was the first program to put a human on the moon. Also, one of the most important satellites in world history is the Hubble Space Telescope. It has allowed astronomers to view areas of space at a greater resolution than ever before, and has shed new light on black holes, nebulae and star formation, and the history of the universe.
