Issued by the Soviet Union in 1977, this 10-kopeck commemorative stamp celebrates the Soyuz 24 mission and its successful docking with the Salyut 5 space station. It features portraits of cosmonauts Viktor V. Gorbatko and Yuri N. Glazkov, the crew of the second expedition to Salyut 5. The stamp’s vivid design depicts a rocket launch against the Earth, symbolizing Soviet achievements in orbital research. Soyuz 24 was notable for testing life-support and environmental systems, marking a key moment in the USSR’s long-duration spaceflight program.
