The Soviet Union launches Soyuz 9, a long-endurance mission which becomes the longest space flight in human history to date, lasting 18 days. Biomedical measurements are taken of cosmonauts Andrian Nikolayev and Vitaly Sevastyanov throughout their two-and-a-half-week stay in orbit, and Soyuz 9 is seen as a trailblazer for the Soviet space program’s new focus of long-term crewed space stations. Both cosmonauts suffer from muscle loss during their flight, as the Soyuz capsule isn’t big enough to allow for exercise.

The Soviet Union launches unmanned space probe Luna 16 toward the moon, the first success in the Soviet space program’s ongoing attempt to mount a robotic sample return mission. The lander’s drill-equipped sample collection arm gathers a 35 millimeter, 100-gram core sample of lunar soil, which is then packed into a shielded return capsule for direct return to Earth (seen here after landing). Now claiming that they advocate robotic sample return missions without putting human lives at risk, the Soviets can at last claim a lunar first – the first robotic return to Earth of a soil sample from another body in the solar system.
