- 03 Jun Soyuz 36 mission completion: The Soyuz 36 mission, launched on May 26, 1980, concluded on June 3, 1980, with the safe landing of cosmonauts Valery Kubasov and Bertalan Farkas. During their stay aboard the Salyut 6 space station, they conducted various scientific experiments, including measuring radiation doses received by the crew and studying the formation of interferon in human cells under weightless conditions. The mission was part of the Soviet Intercosmos program, which aimed to involve allied nations in space exploration. source: en.wikipedia.org
- 18 Jul India's first satellite launch: Rohini RS-1: On July 18, 1980, India successfully launched its first satellite, Rohini RS-1, using the indigenously developed Satellite Launch Vehicle (SLV-3). This achievement marked India's entry into the group of nations capable of launching satellites into orbit. The 35 kg spin-stabilized satellite was placed into a low Earth orbit with a perigee of 305 km and an apogee of 919 km, and it remained operational for approximately 20 months. source: isro.gov.in
- 23 Jul Phạm Tuân becomes first Vietnamese cosmonaut in space: On July 23, 1980, Vietnamese pilot Phạm Tuân embarked on the Soyuz 37 mission, becoming the first Vietnamese citizen and the first person of Asian origin to travel into space. Accompanied by Soviet cosmonaut Viktor Gorbatko, Tuân conducted scientific experiments aboard the Salyut 6 space station, including studies on mineral melting in microgravity and plant growth. The mission lasted nearly eight days, and they returned to Earth on July 31, 1980. source: britannica.com
- 31 Jul Soyuz 37 crew returns to Earth aboard Soyuz 36: On July 31, 1980, cosmonauts Viktor Gorbatko and Pham Tuân returned to Earth aboard the Soyuz 36 spacecraft after an eight-day mission to the Salyut 6 space station. Pham Tuân, the first Vietnamese cosmonaut, conducted experiments observing Vietnam from space and testing the growth of Vietnamese azolla water ferns, with applications to future closed-loop life support systems. source: en.wikipedia.org
- 01 Oct Soviet cosmonauts set new space endurance record: On October 1, 1980, Soviet cosmonauts Leonid Popov and Valery Ryumin surpassed the previous space endurance record of 175 days and 35 minutes, achieving a new record of 185 days in orbit aboard the Salyut 6 space station.

Their mission began on April 9, 1980, and during this period, they hosted four visiting crews, including the first Hungarian, Cuban, and Vietnamese cosmonauts. source: washingtonpost.com
- 31 Oct Julian Nott sets hot-air balloon altitude world record: On October 31, 1980, Julian Nott piloted a hot-air balloon to a world record altitude of 55,134 feet (16,805 meters) from Longmont, Colorado. This achievement was the culmination of his innovative work in designing the first pressurized cabin for a hot-air balloon, which significantly enhanced the safety and performance of high-altitude flights. The cabin from this record-setting flight is now on permanent display at the Smithsonian National Air and Space Museum. source: airandspace.si.edu
- 11 Nov Soviet Soyuz 35 crew returns to Earth aboard Soyuz 37: On November 11, 1980, cosmonauts Leonid Popov and Valery Ryumin concluded their 185-day mission aboard the Salyut 6 space station, returning to Earth in Soyuz 37. Their mission set a new space endurance record at the time. source: britannica.com
- 12 Nov Voyager 1 captures detailed images of Saturn's moon Janus: On November 12, 1980, NASA's Voyager 1 spacecraft captured detailed images of Saturn's moon Janus, revealing its size and co-orbital relationship with Epimetheus. These observations confirmed Janus's dimensions and its shared orbit with Epimetheus, both completing a revolution around Saturn every 16 hours and 40 minutes at a distance of approximately 151,000 kilometers. source: nssdc.gsfc.nasa.gov
- 27 Nov Soyuz T-3 mission to Salyut 6: On November 27, 1980, the Soviet Union launched Soyuz T-3, the first Soyuz spacecraft to carry three cosmonauts since 1971. The crew—Leonid Kizim, Oleg Makarov, and Gennady Strekalov—docked with the Salyut 6 space station on November 28, 1980, and conducted maintenance and repairs, including overhauling the thermal control system and replacing electronics in the telemetry system.
