Apollo ran from 1961 to 1972, and was supported by the two-man Gemini program which ran concurrently with it from 1962 to 1966. Gemini missions developed some of the space travel techniques that were necessary for the success of the Apollo missions. Apollo used Saturn family rockets as launch vehicles. Apollo/Saturn vehicles were also used for an Apollo Applications Program, which consisted of Skylab, a space station that supported three manned missions in 1973–74; and the Apollo–Soyuz Test Project, a joint Earth orbit mission with the Soviet Union in 1975.
The Apollo program succeeded in achieving its goal of manned lunar landing, despite the major setback of a 1967 Apollo 1 cabin fire that killed the entire crew during a pre-launch test. After the first landing, sufficient flight hardware remained for nine follow-on landings, with a plan for extended lunar geological and astrophysical exploration. Budget cuts forced the cancellation of three of these. Five of the remaining six missions achieved successful landings, but the Apollo 13 landing was prevented by an oxygen tank explosion in transit to the Moon, which disabled the command spacecraft's propulsion and life support. The crew returned to Earth safely by using the Lunar Module as a "lifeboat" for these functions.
On August 16, 2005 at 1:44 a.m. EDT he passed the record of 748 days held by Sergei Avdeyev. He now has spent a total of 803 days and 9 hours and 39 minutes in space.
Krikalev was born in Leningrad (now St. Petersburg), Russia. He enjoys swimming, skiing, cycling, aerobatic flying, and amateur radio operations, particularly from space (callsigns U5MIR and X75M1K).
On February 15, 2007, Krikalev was appointed Vice President of the S.P. Korolev Rocket and Space Corporation Energia (Russian: Ракетно-космическая корпорация "Энергия" им. С.П.Королева) in charge of manned space flights.
Krikalev was dubbed by many "the last Citizen of the USSR " as in 1991–1992 he spent 311 days, 20 hours and 1 minute aboard the Mir space station while, back on Earth, the Soviet Union collapsed. A fictional account of how Krikalev may have felt about this is described in the song "Casiopea", written by Cuban songwriter Silvio Rodríguez.
…that the backup crew of Apollo 11 consisted of Jim Lovell, Bill Anders and Fred Haise, although after Anders announced his intention to retire, Ken Mattingly was also assigned in case the mission was delayed until after Anders had left? The backup crew, with Mattingly replacing Anders, was later assigned to Apollo 13.
