Astronaut Michael Collins, the command module pilot for the Apollo 11 moon landing mission, passed away on Wednesday. Collins was 90.

“I am too old to fly to Mars, and I regret that. But I still think I have been very, very lucky. I was born in the days of biplanes and Buck Rogers, learned to fly in the early jets, and hit my peak when moon rockets came along. That’s hard to beat.” —Michael Collins
