On July 17, 1975, US spacecraft Apollo 18 and Soviet Union's Soyuz 19 docked in space to create history. During the 44-hour Apollo-Soyuz rendezvous, astronauts and cosmonauts conducted experiments, shared meals, and held a joint news conference. A NASA astronaut later said, "If the Soviet Union and America could work together in space, they could work together on the Earth."
