Fare thee well, Alan Bean, and thank you. 

It has been, and continues to be, a heartbreak to lose people who have dared to do great things.

With Alan Bean’s passing, there are just four living people who have walked on the moon:

Dave Scott & Jim Irwin, Apollo 15: July 30 to August 2, 1971

Charlie Duke, Apollo 16: April 21-24, 1972

Harrison “Jack” Schmitt, Apollo 17: December 11-14, 1972
