Q. Who has spent the most time in space? — Leander McD.
A. Russian cosmonaut Sergei Krikalev, for more than two years.
On August 16, 2005, International Space Station commander Sergei Krikalev surpassed the record for most cumulative time spent in space by any person. On that date, his accumulated total during six flights passed 749 days in space. The previous record had been 747 days, 14 hours, 14 minutes and 11 seconds held by fellow Russian cosmonaut Sergei Avdeyev. When Krikalev returns to Earth from the ISS, he will have 815 or more days in space.

Krikalev was born in 1958 in the former Soviet Union at Leningrad – now St Petersburg, Russia. He was selected to be a cosmonaut in 1985 and completed his basic training in 1986. He has been a member of the Russian and Soviet national aerobatic flying teams and has been awarded various titles, including Hero of the Soviet Union and the Order of Lenin.

During his 20-year career, Krikalev lived aboard Russia's former Mir space station. He made his first long-duration mission to Mir in 1988. The cosmonaut flew aboard U.S. shuttle Discovery flight STS-60, the first joint US-Russian shuttle mission in 1994. He also was a member of the first crew to live aboard the International Space Station. Among his six trips to space, Krikalev has made three long duration flights. One was aboard Mir and two were on the ISS.

Russian record holders. Avdeyev's record of some 748 days in space was accumulated on three flights.

Cosmonaut and doctor Valery Polyakov set the world single-flight endurance record in 1994-1995, when he completed a 437.7-day mission aboard Soyuz TM-18.

A recent space traveler, Russian cosmonaut Alexander Kaleri, is among the most experienced space travelers, having logged more than 610 days in orbit on four flights, placing him fifth on the all-time space endurance list.

U.S, record holders. Foale has been a member of six space shuttle crews and two space station crews. He was aboard U.S. space shuttles in 1992, 1993, 1995, 1997 and 1999. He was a flight engineer aboard Russia's Mir space station in 1997 and was commander of the International Space Station in 2003-2004. Foale traveled to the ISS on board a Russian Soyuz spacecraft.

U.S. astronaut Carl Walz had held the record before Foale with 230 days, 13 hours, three minutes and 37 seconds in space.

Walz still is co-holder, with astronaut Daniel Bursch, of the record for the longest single U.S. spaceflight. Walz and Bursch spent nearly 196 days aboard the International Space Station as Expedition crew 4.

American astronaut Shannon Lucid holds the single flight and cumulative record for time in space by a woman. She had a 188-day flight aboard Russia's Mir space station contributing to a cumulative total of 223 days in space on five flights.
