Superpowers Shake Hands in Orbit

The U.S. and Soviet Union signed an agreement paving the way for the 1975 Apollo-Soyuz Test Project, the first joint superpower spaceflight of the Cold War.

Signed during Richard Nixon's Moscow summit, the agreement committed NASA and the Soviet space program to design compatible docking systems, enabling American and Soviet spacecraft to link up in orbit. Three years later, an Apollo capsule and a Soyuz craft docked 140 miles above Earth, and astronauts and cosmonauts shook hands through the open hatch — a symbolic thaw amid ongoing Cold War rivalry.
