In 1971 the Soviet Union sent probes Mars 2 and Mars 3, each carrying a lander, as part of the Mars probe program M-71. The Mars 2 lander failed to land and impacted Mars. The Mars 3 lander became the first probe to successfully soft-land on Mars, but its data-gathering had less success. The lander began transmitting to the Mars 3 orbiter 90 ...
By Eric Sandler On August 20, 1975 -- 39 years ago today -- NASA launched the first of two spacecraft as a part of their new Viking program and the images they captured back in the '70s and '80s ...
Lander Partial success [10] [11] First lander to make a soft landing on Mars. Landed on 2 December 1971. First partial image (70 lines) transmitted showing "gray background with no details". [8] Contact lost 20 seconds after transmission started, 110 seconds after landing. [12] [13] PrOP-M: Rover Carrier vehicle failed before rover was deployed
The assembly orbited Mars many times before the lander was released and separated from the orbiter for descent to the surface. Descent comprised four distinct phases, starting with a deorbit burn. The lander then experienced atmospheric entry with peak heating occurring a few seconds after the start of frictional heating with the Martian ...
