NASA Apollo astronaut Walt Cunningham has died at age 90

One of the early Apollo astronauts has died. Walt Cunningham died Tuesday after complications from a fall. He was 90.

Walt Cunningham flew in space just one time. His flight in 1968 was an important — and often forgotten one — for the lunar program.

Cunningham was the lunar module pilot of the first manned Apollo mission that went to space. Apollo 7's 11-day trip around the Earth was a key stepping stone to NASA's march to the moon.
