Há 16 horas · Mars-1 was the first spacecraft launched to Mars in 1962, but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of Mars.
Há 3 dias · The spacecraft scientific payload consisted primarily of three television cameras designed to image the surface of Mars. The cameras had three color filters and two lenses, a 50-mm lens with a nominal field of view of 1500 x 1500 km and a 350-mm lens which had a field of 100 x 100 km. An image was 1024 x 1024 pixels for a maximum resolution of ...
