Passage: She was named to the Rogers Commission (the presidential commission investigating the accident) and headed its subcommittee on operations. She was the only person to serve on both of the panels investigating shuttle accidents (those for the Challenger accident and later the Columbia disaster). Following the Challenger investigation, Ride was assigned to NASA headquarters in Washington, D.C., where she led NASA's first strategic planning effort, authored a report titled "NASA Leadership and America's Future in Space" and founded NASA's Office of Exploration. After Sally Ride's death in 2012, General Donald Kutyna revealed that she had discreetly provided him with key information about O-rings (namely, that they become stiff at low temperatures) that eventually led to identification of the cause of the explosion.
