Decay Date: 1962-10-29 . USAF Sat Cat: 443 . COSPAR: 1962-B-Iota-1. Apogee: 260 km (160 mi). Perigee: 202 km (125 mi). Inclination: 65.1000 deg. Period: 89.10 min.

  Mars probe intended to photograph Mars on a flyby trajectory. The spacecraft broke into many pieces, some of which apparently remained in Earth orbit for a few days. This occurred during the Cuban missile crisis and was picked up by U.S. military radar installations, who originally feared it might by the start of a Soviet nuclear attack.

• Mars 1 - . Payload: 2MV-4 s/n 4 / Sputnik 23. Mass: 894 kg (1,970 lb). Nation: Russia. Agency: RVSN. Program: Mars. Class: Mars. Type: Mars probe. Spacecraft Bus: 2MV. Spacecraft: Mars 2MV-4. USAF Sat Cat: 450 . COSPAR: 1962-B-Nu-3.

  Mars probe intended to photograph Mars on a flyby trajectory. Launched from Sputnik 23 in a 157 x 238 km, 65 degree parking orbit. Sixty-one radio transmissions were held in which a large amount of data was collected. On March 21, 1963, when the spacecraft was at a distance of 106 million km communications ceased, possibly due to a malfunction in the spacecraft orientation system. Mars 1 closest approach to Mars occurred on June 19, 1963 at a distance of approximately 193,000 km, after which the spacecraft entered a heliocentric orbit. Announced mission: Prolonged exploration of outer space during flight to the planet Mars; establishment of inter-planetary radio communications; photgraphing of the planet Mars and subsquent radio-transmission to Earth of the photographs of the surface of Mars thus obtained.
