The Astounding Gemini 4 Mission

Gemini 4 pilot Ed White could see Hawaii, California, Texas, and Florida. Millions of Americans had seen these places before, but White had a unique view. He looked at them while walking in space. One hundred miles above Earth and moving freely outside the Gemini 4 spacecraft, White saw these states as tiny stepping stones. The first American spacewalk was a monumental achievement, and it helped push the space program toward its ultimate goal of landing men on the Moon. From the brave astronauts to the technology that made it possible, author Carl R. Green explores the astounding Gemini 4 mission.
