Mars 1 was a modified Venera-type spacecraft in the shape of a cylinder 3.3 m (11 ft) long and 1 m (3.3 ft) in diameter. Mars 1 closest approach to the planet Mars probably occurred on June 19, 1963 at a distance of approximately 193,000 km (120,000 mi), after which the spacecraft entered an orbit around the Sun.
The spacecraft is also referenced as Sputnik 23 and Mars 2MV-4. It was originally designated Sputnik 30 in the U.S. Naval Space Command Satellite Situation Summary.
Although it was called Mars 1, there was at least three other probes prior to this Mars 2MV-4 No.1, Mars 1M No.2, and Mars 1M No.1.
