First, I just wanna note:
Don's one of my favorite (and currently oldest) active astronauts, so that's nice. Anywayz...in a glibly related vein, today marks the 64th anniversary of Mercury-Atlas 7, with Scott Carpenter piloting Aurora 7 for a modest three orbits:
The original pilot selected for Mercury Atlas-7 was to have been Deke Slayton, with Wally Schirra as his backup. However Slayton was removed from flight status after the discovery of idiopathic paroxysmal atrial fibrillation during a training run in the g-loading centrifuge. Slayton had chosen the name Delta 7 for the spacecraft, as this would have been the fourth crewed flight and Delta (Ξ) is the fourth letter in the Greek alphabet.
Instead of using Schirra, who was backup, it was decided to give the mission to Carpenter, who was the backup crew for Mercury-Atlas 6, had trained with John Glenn, and was considered the best-prepared astronaut. When Carpenter was given the mission, he renamed it Aurora 7 for the open sky and the dawn, symbolizing the dawn of the new age. The number Seven was also chosen for the Mercury 7 astronauts.
In addition, Carpenter's home address in his childhood was the corner of Aurora Ave. and Seventh St. in Boulder, Colorado, although at a talk he gave at the Boulder Theater in 2003, Carpenter admitted that he never made the connection between the Aurora 7 spacecraft and the address of his youth until friends pointed it out to him after he made the flight...
The performance of the Mercury spacecraft and Atlas launch vehicle was excellent in nearly every respect. All primary mission objectives were achieved. The single mission-critical malfunction which occurred involved a failure in the spacecraft pitch horizon scanner, a component of the automatic control system. This anomaly was adequately compensated for by the pilot in subsequent in-flight operations so that the success of the mission was not compromised.
A modification of the spacecraft control-system thrust units was effective. Cabin and pressure-suit temperatures were high but not intolerable. Some uncertainties in the data telemetered from the bioinstrumentation prevailed at times during the flight; however, associated information was available which indicated continued well-being of the astronaut...
Other than slight exhaustion, Carpenter was in good health and spirits and post-flight medical exams did not find any significant physical changes or anomalies. Kraft, however, was unhappy with the astronaut's performance due to his needlessly high expenditure of attitude control fuel, which resulted in reentry and landing taking place well off-course. As a result, Carpenter was sidelined for future missions. He left the space program in 1964 to participate in the Navy's SEALAB program. Aurora 7 is displayed at the Museum of Science and Industry in Chicago, Illinois.
A little more about Chris Kraft's attitude:
Kraft did not hesitate to assign blame to Carpenter, and continued to speak out about the mission for decades afterwards. His autobiography, written in 2001, reopened the issue; the chapter that dealt with the flight of Mercury-Atlas 7 was titled "The Man Malfunctioned". In a letter to The New York Times, Carpenter called the book "vindictive and skewed", and offered a different assessment of the reasons for Kraft's frustration: "in space things happen so fast that only the pilot knows what to do, and even ground control can't help. Maybe that's why he is still fuming after all these years."
Kraft was critical to the birth of our space program, and I generally like him, but I think he was being a dick here. From This New Ocean: A History of Project Mercury:
In [the] postflight sessions the astronaut insisted that he knew what he wanted to do at all times, but that every task took a little longer than the time allotted by the flight plan. Some of the equipment, he said, was not easy to handle, particularly the special films that he had to load into a camera...
Moreover, the flight plan that had been available during training was only a tentative one, and the final plan had been completed only a short while before he suited up for the launch. Carpenter felt that the completed plan should be in the astronaut's hands at least two months before a scheduled flight and that the flight agenda should allow more time for the pilot to observe, evaluate, and record...
Talking with newsmen after the flight, Carpenter assumed full responsibility for his high fuel consumption. He pointed out, however, that what he had learned would be valuable for longer Mercury missions.
That issue about time is particularly important, as that was a theme throughout the early days of our space endeavors. Everything people on the ground thought would be easy ended up being much more complicated and time-consuming in orbit. A point that I think Kraft didn't seem to internalize.
But whatever. We've certainly learned a lot more since then thanks to workhorses like Don Pettit and his 590 days (approx 9,440 orbits) in space.
