March 21 in Universe History: Space Missions, Satellites and Exploration
March 21, 2026
1999
On 21 March 1999, an International Launch Services Proton rocket lifted off from Baikonur and carried the AsiaSat 3S commercial communications satellite into geosynchronous transfer orbit, demonstrating late-1990s heavy-lift commercial launch operations and enabling additional regional telecom capacity after on-orbit raising, testing, and handover to the satellite operator.
2018
On 21 March 2018, Soyuz MS-08 lifted off from Baikonur carrying Oleg Artemyev and NASA astronauts Drew Feustel and Ricky Arnold on a two-day flight to the International Space Station, sustaining uninterrupted human orbital residency. The launch began their Expedition 55/56 increment and set up docking and hatch operations planned for March 23.
2022
On 21 March 2022, OneWeb said it had contracted with SpaceX to launch its satellites after Russia forced an eleventh-hour cancellation of a planned Baikonur mission, shifting providers in the broadband-constellation market and showing how geopolitics can reshape access to launch services and deployment schedules for space networks.
2024
On 21 March 2024, the Soyuz 71S launch from Baikonur was scrubbed on the pad. NASA stated that astronaut Tracy Dyson, cosmonaut Oleg Novitskiy, and participant Marina Vasilevskaya were safe along with the spacecraft, showing how late scrubs can delay crew rotations and require fast replanning of station timelines and vehicle traffic.
