April Flowers for redOrbit.com - Your Universe Online The catastrophic melting and outflow of a buried ice lake formed the lumpy, bumpy floor of an ancient impact crater on Mars known as Aram Chaos. Satellite observations of the 173 mile wide and 2.5 mile deep crater were combined with models of the ice melting process and resulting catastrophic outflow for a new study presented at the European Planetary Science Congress (EPSC) at UCL in London by Michael Roda of the Utrecht University....

Lee Rannals for redOrbit.com The European Space Agency's Mars Express has found evidence that underground water used to exist during the first billion years of Mars' existence. ESA's Mars Express and NASA's Mars Reconnaissance Orbiter zoomed in on craters in part of the region of the ancient southern highlands called Tyrrhena Terra. Scientists were able to identify 175 sites bearing minerals formed in the presence of water by focusing in on the chemistry of rocks embedded in the...

The European Space Agency says its Mars Express spacecraft has discovered some depositional process in Mars' equatorial regions. Scientists said the geological evidence, revealed by erosion, comes from the mineralogical composition of the Aram Chaos region, a crater about 175 miles in diameter located nearly directly on the martian equator. The ESA said the spacecraft's instrumentation suggests a significant amount of sulfates and ferric oxides. On Earth, ferric oxide is more commonly known...

Mars Express has uncovered geological evidence suggesting that some depositional process, revealed by erosion, has been at work on large scales in the equatorial regions of the planet. If so, this would provide another jigsaw piece to be fitted into the emerging picture of Mars' past climate. The evidence comes from the mineralogical composition of the Aram Chaos region, a crater 280 km in diameter lying almost directly on the martian equator. Data from Mars Express' OMEGA instrument, the...

When Mars was still young, more than four billion years ago, a large asteroid sailed out of the sky and slammed into an area known today as western Arabia Terra. The object hit hard enough that it blasted a basin at least 280 kilometers (175 miles) wide. The basin is now named Aram Chaos. As many millions of years passed, into this yawning bowl drifted sediments of many kinds - wind-blown dust, sand, and volcanic ash. The Martian climate was wetter then, so the crater-filling debris became...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) aboard ESA's Mars Express spacecraft, show a large depression called Iani Chaos and the upper reaches of a large outflow channel called Ares Vallis. Image strips were taken in October 2004, during three orbits from a 350-kilometre altitude, with a resolution of 15 metres per pixel. The strips have then been matched to a mosaic that covers an area from 17.5º western longitude to 3º...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the 'chaotic' terrain of the Aureum Chaos region on Mars. The HRSC obtained these images during orbit 456 with a resolution of approximately 25 metres per pixel. The scenes show an area located at about 3º South and 335º East. Aureum Chaos is located in the eastern part of Valles Marineris, south-west of the 280 kilometre-wide impact crater...
