Sich-1 was the first Ukrainian Earth observation satellite launched in August 1995 by Ukrainian Tsyklon-3 rocket from Plesetsk Cosmodrome in Russia. It operated until 2001. In this launch was also launched the first satellite of Chile, FASat-Alfa, that failed to detach from Sich-1. Both satellites, attached together, continue to orbit the Earth as of 2026.
