Scientists who read 16 years of radio tracking from three Mars orbiters say the mantle beneath the planet's southern highlands runs 200 to 400 degrees Celsius hotter, averaged over the whole depth of the mantle, than the mantle beneath the northern plains, an inference drawn from the way Mars flexes under the Sun across each Martian year
1+ week, 20+ hour ago (307+ words) The tracking shows Mars deforming in a way a uniform planet should not, and the least strained explanation is a hemisphere of mantle that something is still keeping warm. By Science Blog Editorial Team · Edited by Christy Suriadi Published September…...
Mars' South Pole is hiding a strange underground heat anomaly
1+ week, 5+ day ago (377+ words) Mars has always been a planet of contrasts. Its northern hemisphere is a vast, flat lowland, while the southern half is rugged with towering mountains and deep craters. Now scientists have discovered that this asymmetry extends deep beneath the surface:…...

A meteorite from Mars reveals traces of ancient water in the Martian crust
3+ week, 9+ hour ago (435+ words) An international team of scientists may have taken another step toward reconstructing the history of water on Mars—and, more specifically, toward determining the amount of water that may once have flowed across its surface, according to the website “Knowridge....
Dry Martian Meteorite Reveals Early Water in Mars's Crust
3+ week, 22+ hour ago (507+ words) Billions of years ago, Mars was hypothesized to have been a habitable world with flowing liquid water and the potential for life. But directly studying its ancient past is currently limited to orbiters and rovers, as scientists have yet to…...

Mars can snow carbon dioxide at its poles, while some of its warmest summer landscapes grow dry-ice frost overnight that vanishes back into gas after sunrise
1+ mon, 1+ day ago (583+ words) Mars can produce snow from carbon dioxide near its winter poles. Far from those seasonal caps, however, the same material can appear in a quieter and more...
