Summary
DescriptionMarsCrustThickness.jpg
English: Newly detailed mapping of local variations in Mars' gravitational pull on orbiters (center), combined with topographical mapping of the planet's mountains and valleys (left) yields the best-yet mapping of Mars' crustal thickness (right). The data come from many years of using NASA's Deep Space Network to track positions and velocities of NASA's Mars Global Surveyor, Mars Odyssey and Mars Reconnaissance Orbiter.
These three views of global mapping are centered at 90 degrees west longitude, showing portions of the planet that include tall volcanoes on the left and the deep Valles Marineris canyon system just right of center. Additional views of these global maps are available at http://svs.gsfc.nasa.gov/goto?4436.
Русский: Карта толщины коры Марса (справа), составленная на основании последних точных данных об интенсивности гравитационного поля (в середине) и топографической карте высот (слева). Гравитационное поле измерялось в течение нескольких лет орбитальными аппаратами Mars Global Surveyor, Mars Odyssey и Mars Reconnaissance Orbiter, а их положения и скорости отслеживались Сетью дальней космической связи НАСА.
Показана часть поверхности Марса, включающая высокие вулканы слева и крупнейшую систему каньонов долины Маринер справа от центра - меридиана 90° западной долготы.
