Soyuz TM-21 was Soyuz mission, a human spaceflight mission transporting personnel to the Russian space station "Mir". Part of the US/Russian Shuttle-Mir Program, the mission launched from Baikonur Cosmodrome, atop a Soyuz carrier rocket, at 06:11:34 UTC on March 14 1995. It is of note because its launch marked the presence, for the first time ever, of thirteen humans in space simultaneously - three aboard the Soyuz, three aboard "Mir" and seven aboard Space Shuttle "Endeavour", flying STS-67.

The spacecraft carried expedition EO-18 to the space station, including the first American astronaut to launch on a Soyuz spacecraft and board "Mir", Norman Thagard, for the American Thagard Increment aboard the station, the first Increment of the Shuttle-Mir program. The three crew members it launched were relieved by Space Shuttle "Atlantis" during STS-71, when they were replaced by expedition EO-19, who returned to earth aboard Soyuz TM-21 on September 11 1995.
