Fifty years ago, on July 15, 1975, three NASA astronauts and two Russian cosmonauts lifted off to meet up in orbit for the first time.
Representing the joint Apollo-Soyuz Test Project (ASTP, or Soyuz-Apollo in the Soviet Union), both crews wore a cloth patch that featured the artwork of an accomplished space artist. The design that flew, however, was not the astronauts’ first pick. That patch idea was rejected because Paul Calle opted to highlight the détente nature of the international handshake in space.
“Our first choice for a patch… has been disapproved,” wrote Deke Slayton, the mission’s docking module pilot, in a letter to Calle. “It seems the powers that be are not that into peace doves and olive branches at the moment.”
