Mars 3 was a robotic space probe of the Soviet Mars program, launched May 28, 1971, nine days after its twin spacecraft Mars 2. The probes were identical robotic spacecraft launched by Proton-K rockets with a Blok D upper stage, each consisting of an orbiter and an attached lander .
The Mars 2 and Mars 3 missions consisted of identical spacecraft, each with a bus/orbiter module and an attached descent/lander module. The primary scientific objective of the Mars 3 descent module was to perform a soft landing on Mars, return images from the surface, and return data on meteorological conditions, atmospheric composition, and ...
The lander for Mars 2 crashed on the surface of Mars. The lander of Mars 3 reached the surface, but its transmissions soon disappeared. However, the orbiters of Mars 2 and Mars 3 continued circling the planet for 8 months sending images to Earth. In June 1973, Mars 4 and Mars 5 were launched.
The Soviet Mars 3 lander claimed a technical first with a survivable landing in 1971, but contact was lost seconds after it touched down. Both NASA Viking missions used a combination of orbiter and lander to explore Mars in unprecedented detail.
