NASA’s 50th space shuttle mission, STS-47, landed safely at the Kennedy Space Center in Florida.

It was the second time the Endeavour space shuttle made it into space and back, this time carrying the first Japanese astronaut, Mamoru Mohri, into space. That wasn’t the only first for the mission, though, with Mae C Jemison becoming the first African American in space and Mark C. Lee and N. Jan Davis becoming the first married couple to fly on the same shuttle. Mark and Jan kept their marriage secret until the last minute, as NASA had an unofficial policy preventing married couples from flying together. It was too late to change anything by the time NASA found out.
