Only 9 still living that flew on Apollo, and only 4 left that walked on the moon.Man, losing those two pioneers so close together has been rough for a Space nerd like me. Mattingly played such a big role in getting XIII back and got a mission of his own as CMP before flying on the Shuttle. Borman spent a lot of time in space for his two missions. Two weeks with Jim Lovell on Gemini VII and 6 days on Apollo 8 with Lovell again and Bill Anders, and he was the lone astronaut for the investigation into the Apollo 1 disaster. May these heroes rest in peace.
Only 5 left that flew on Gemini.
