AKA: 1M. Status: Operational 1960. First Launch: 1960-10-10. Last Launch: 1960-10-14. Number: 2 . Gross mass: 640 kg (1,410 lb).

The Mars probe had a mass of about 640 kg and carried a magnetometer, cosmic ray counter, plasma-ion trap, and micrometeorite detector.

• Further development of Soviet Lunar and Planetary probes approved. - . Nation: Russia. Spacecraft: Luna E-6, Mars 1M. Central Committee of the Communist Party and Council of Soviet Ministers Decree 1386-618 'On the Creation of AMS for Landing on the Moon. and Flights to Venus and Mars-- approving automated lunar and interplanetary spacecraft' was issued..

• Mars probe 1M s/n 1 failure. - . Payload: 1M s/n 1. Mass: 640 kg (1,410 lb). Nation: Russia. Agency: RVSN. Program: Mars. Class: Mars. Type: Mars probe. Spacecraft Bus: 1MV. Spacecraft: Mars 1M. Decay Date: 1960-10-10 .

  This was the Soviet Union's first attempt at a planetary probe. Mars probe intended to photograph Mars on a flyby trajectory. The possible cause lay in resonance vibrations of upper stages during Stage 2 burning, which led to break of contact in the command potentiometer of the gyrohorizon. As a result a pitch control malfunctioned and the launcher began to veer off the desired ascent profile. On exceeding 7 degrees of veering in pitch, the control system failed. The upper stage with the payload reached an altitude of 120 km before burning up on re-entry into the atmosphere above East Siberia.
