On June 6, 1995, NASA astronaut Norman Thagard broke NASA’s space endurance record after spending 84 days, 1 hour and 16 minutes aboard the Russian space station Mir.
Thagard, a veteran of four Space Shuttle flights, was considered the first American cosmonaut and the first American to ride to space aboard a Russian vehicle.
Thagard launched aboard a Soyuz TM-21 spacecraft for the Mir-18 mission on March 18, 1995, and landed on NASA’s space shuttle Atlantis on July 7.
He ultimately spent a total of 115 days in space on the flight.
