Mars
Pathfinder was intended to be an exhibit of the innovation important to convey
a lander and a free-going automated rover to the surface of Mars in a
financially savvy and productive way. Pathfinder fulfilled this objective as
well as gave back an extraordinary measure of information and outlasted its
essential configuration life. Mars Pathfinder utilized a creative technique for
straightforwardly entering the Martian air, helped by a parachute to moderate
its plummet through the slim Martian air and a goliath arrangement of airbags
to pad the effect. The arrival site, an antiquated surge plain in Mars'
northern side of the equator known as Ares Vallis, is among the rockiest parts
of Mars. It was picked in light of the fact that researchers trusted it to be a
moderately safe surface to arrive on and one which contained a wide assortment
of rocks saved amid a cataclysmic surge. The lander, formally named the Carl Sagan
Memorial Station taking after its fruitful touchdown, and the rover, named
Sojourner after American social liberties crusader Sojourner Truth, both
outlasted their configuration lives — the lander by almost three times, and the
rover by 12 times. From arriving until the last information transmission on
September 27, 1997, Mars Pathfinder returned 2.3 billion bits of data,
including more than 16,500 pictures from the lander and 550 pictures from the
rover, and also more than 15 compound investigations of rocks and soil and
broad information on winds and other climate variables. Discoveries from the
examinations completed by exploratory instruments on both the lander and the
rover recommend that Mars was at one time in its past warm and wet, with water existing
in its fluid state and a thicker air. /Nasa.Gov orginal post/
