Objectives
  1. perform a flyby of Mars
  2. study Mars and return surface images
  3. investigate cosmic radiation near Mars
  4. return data on micrometeoroid impacts
  5. study Mars's magnetic field
  6. study the martian atmosphere
  7. identify possible organic compounds




Summary

Launch date: 1 november 1962

Mission status: failed

Mars 1 (also known as 1962 ß ν 1, Mars 2MV-4 and Sputnik 23) was a soviet Mars probe.

Launch was successful, but a leak in one of the gas valves in the orientation system occurred early in the spacecraft's journey to Mars. The craft had to be switched to gyroscopic orientation. About halfway between Earth and Mars, communications with the craft ceased, presumably due to antenna orientation problems.

Mars 1 used a modified Venera design. It was a 3.3-meter-long cylinder one meter in diameter; with the radiators and solar panels fully deployed, it was four meters from end to end.

The upper 2.7 meters contained propulsion and guidance systems, while the rest of the cylinder contained the scientific instruments. The craft also had a parabolic high-gain antenna 1.7 meters long, which it used for communication, and two more antennas.

The two solar panels, which had a total area of 2.6 square meters, provided power; this power was stored in a 42-ampere-hour cadmium-nickel battery.

A decimeter-band radio transmitter in the orbital module provided communication via the high-gain antenna. It was helped by a transmitter which used one of the other two antennas, which operated in the meter band. The images the probe was to transmit back to Earth were to be handled by an 8-centimeter transmitter. Finally, a 5-centimeter transmitter was mounted in the lower, instrument-carrying module of the cylinder.

Hemispherical radiators at the ends of the solar panels and a gas-liquid system controlled the spacecraft's temperature.

Mars 1's scientific payload consisted of a magnetometer, photographic equipment, a spectroreflexometer, two kinds of radiation sensors, a spectrograph, and a micrometeoroid-sensing instrument.

The spacecraft weighed about 893.5 kilograms.
