CAS500-1, (Korean: 국토위성 1호, transl. "Land Satellite No. 1"), is a prototype 500-kilogram (1,100 lb) class Earth observation satellite that was launched by South Korea at the Baikonur Cosmodrome on 22 March 2021.[4][5][6][7] It is in a 500-kilometre (310 mi) Sun-synchronous orbit, inclined by 97.7 degrees or 15 orbits/day.
CAS500-2 was expected to launch in 2022 also on a Russian rocket, but the launch was cancelled after the Russian invasion of Ukraine.[8][9][2][10] The satellite was later rescheduled to launch together with CAS500-4 on a SpaceX Falcon 9 rocket.[11][12][13]
CAS500-3 was launched on 26 November 2025 on the South Korean launch vehicle Nuri.[14][15]
