Walter Cunningham, the last surviving astronaut from the first successful crewed space mission in NASA's Apollo program, died Tuesday in Houston. He was 90.

NASA confirmed Cunningham’s death in a statement but did not include its cause. His family said through a spokesman, Jeff Carr, that Cunningham died in a hospital "from complications of a fall, after a full and complete life.”
