In July 1975, millions of people watched on television as a U.S. Apollo spacecraft docked with a Soviet Soyuz capsule in a crewed mission in orbit that symbolized collaboration between the two superpowers at the height of Cold War enmity.
That remarkable moment 50 years ago is being commemorated on a Soyuz rocket carrying a Russian cargo spacecraft that launched from the Baikonur Cosmodrome in Kazakhstan – early on Friday, Baikonur time – and is scheduled to reach the International Space Station after a two-day trip. The spacecraft is loaded with more than 2.5 tons of fuel, drinking water, food, medicine, science equipment, and other supplies for the crew on the station.
The Soyuz rocket currently heading to the ISS is painted white and blue and has an emblem marking the anniversary of the Soyuz-Apollo docking, which was the first international space mission. It had begun on July 15, 1975, when two Soviet cosmonauts launched from Baikonur and, hours later, three American astronauts blasted off from Cape Canaveral, Florida. The Russians and the Americans connected in space two days later, shaking hands, exchanging gifts, and sharing a meal.
The show of comity in space contrasted with the intense competition between the two global rivals that was known as the “space race,” which included the Soviet launch of the Sputnik satellite into orbit in 1957 and the Apollo 11 landing of American astronauts on the moon in 1969.
“I really believe that we were sort of an example … to the countries. We were a little of a spark or a foot in the door that started better communications,” Apollo astronaut Vance Brand had said, according to a NASA account of the Apollo-Soyuz mission.
Tensions between Russia and the United States escalated after Moscow launched a large-scale invasion of Ukraine in 2022, though relations improved after U.S. President Donald Trump took office for a second term in January. The U.S. and Russian space agencies have continued to collaborate over the course of the protracted war.
Roscosmos, the Russian space agency, refers to the cargo spacecraft currently in orbit as Progress MS-31, while the U.S. agency NASA uses the term Progress 92 because it’s the 92nd Russian resupply craft to launch in support of the International Space Station since its construction began in 1998. The Apollo-Soyuz mission has been described as a precursor of the ISS project.
