Buzz Aldrin propellants, with an expected five and a half month journey from the Earth to Mars, and a return trip to Earth of about the same duration on a twin-cycler. Aldrin continues to research this concept with engineers from Purdue University. In December 2003, Aldrin published an opinion piece in "The New York Times" criticizing NASA's objectives. In it, he voiced concern about NASA's development of a spacecraft "limited to transporting four astronauts at a time with little or no cargo carrying capability" and declared the goal of sending astronauts back to the Moon was "more like reaching for past glory
Buzz Aldrin eight minutes after the Agena had been launched, it had suffered a loss of chamber pressure. The Mission and Flight Directors therefore decided not to risk the main engine. This would be the only mission objective that was not achieved. Instead, the Agena's secondary propulsion system was used to allow the spacecraft to rendezvous with a total eclipse over South America on November 12, which Lovell and Aldrin photographed through the spacecraft windows. Aldrin performed three EVAs. The first was a standup EVA on November 12, in which the spacecraft door was opened and he stood up, but did not
