Apollo 11 command module pilot Michael Collins, who remained in the command module Columbia in orbit of the moon while his crewmates, Neil Armstrong and Buzz Aldrin, landed on the moon, dies at the age of 90 after battling cancer. Upon returning to Earth, Collins opted to retire from NASA and found work within the United States government, leading to his becoming the first director of the National Air & Space Museum, a facility which had yet to open at the time he took charge of it. Collins wrote a memoir, Carrying The Fire, in 1974, one of the earliest astronaut memoirs (and the first from a member of the crew charged with making the first lunar landing). Prior to Apollo 11, he had flown with John Young aboard Gemini 10, and prior to that had distinguished careers as both a fighter pilot and a test pilot. He applied for the second group of NASA astronauts, but didn’t make the cut until NASA was recruiting its third class.
