Carpenter's performance in space was the subject of criticism and controversy. NASA's 1989 official history of Project Mercury says that until the third pass over Hawaii, Christopher C. Kraft Jr. (who directed the flight from Cape Canaveral) "considered this mission the most successful to date; everything had gone perfectly except for some overexpenditure of hydrogen peroxide fuel," However, then problems occurred and Kraft wrote in his 2001 memoir “He was completely ignoring our request to check his instruments... I swore an oath that Scott Carpenter would never again fly in space."
