when did the first probe land on mars
Exploration of Mars The first to contact the surface were two Soviet probes: Mars 2 lander on November 27 and Mars 3 lander on December 2, 1971â€”Mars 2 failed during descent and Mars 3 about twenty seconds after the first Martian soft landing.[13] Mars 6 failed during descent but did return some corrupted atmospheric data in 1974. [14] The 1975 NASA launches of the Viking program consisted of two orbiters, each with a lander that successfully soft landed in 1976. Viking 1 remained operational for six years, Viking 2 for three. The Viking landers relayed the first color panoramas of Mars.[15]

Moon landing To date, the United States is the only country to have successfully conducted manned missions to the Moon, with the last departing the lunar surface in December 1972.
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
