Mars 1 was launched in 1962 but failed en route to Mars. Two other Soviet launches at around the same time, [[Mars 2MV-4 No.1]] and [[Mars 2MV-3 No.1]] were {{convert|900|kg|lb|adj=on}} spacecraft, however both failed to leave Earth orbit due to problems with the upper stages of their carrier rockets.
