1975’s other international space mission

The 1972 Space Cooperation Agreement, whose most obvious effect is the Apollo-Soyuz Test Project earlier in the year, bears more fruit in the form of the first unmanned international research mission. American experiments are launched aboard a Soviet Cosmos satellite for the first time, along with experiment packages prepared by French, Czech, Polish, Romanian, and Hungarian scientists. Cosmos 782, the third “Biocosmos” flight, ends after 19 days, with the experiments landed safely in Siberia at the conclusion of the flight.
