"Today General Tom Stafford went to the eternal heavens which he so courageously explored as a Gemini and Apollo astronaut as well as a peacemaker in Apollo Soyuz," NASA Administrator Bill Nelson said via X, formerly known as Twitter. "Those of us privileged to know him are very sad but grateful we knew a giant."
After he put away his flight suit, Stafford was the go-to guy for NASA when it sought independent advice on everything from human Mars missions to safety issues to returning to flight after the 2003 space shuttle Columbia accident. He chaired an oversight group that looked into how to fix the then-flawed Hubble Space Telescope, earning a NASA public service award.
