Former astronaut Bruce McCandless II, a retired Navy captain and son of a Medal of Honor winner who joined NASA during the buildup to the Apollo program, served as capsule communicator when Neil Armstrong took his historic first step on the moon and later flew in space twice during the shuttle program, died Thursday. He was 80.

Two-and-a-half months after cosmonaut Alexey Leonov became the first human to walk in space, NASA astronaut Ed White floated out of his cramped Gemini 4 capsule 50 years ago Wednesday to become the first American spacewalker.
