On July 15, 1975, the first joint space mission between the United States and the Soviet Union blasted off into orbit. They called it the Apollo-Soyuz Test Project.
This mission ceremoniously marked the end of the space race.
First, Russian cosmonauts Alexey Leonov and Valery Kubasov lifted off from Kazakhstan. A few hours later, NASA astronauts Thomas Stafford, Vance Brand and Donald “Deke” Slayton lifted off from Florida’s Kennedy Space Center in an Apollo command module.
Two days later, the spacecraft rendezvoused and docked in orbit, and the two crews greeted each other with what became the first international handshakes to happen in space.
