Latest Aram Chaos Stories
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.
The European Space Agency's Mars Express has found evidence that underground water used to exist during the first billion years of Mars' existence.
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.
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.
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.
These images, taken by the High Resolution Stereo Camera (HRSC) aboard ESAâ€™s Mars Express spacecraft, show a large depression called Iani Chaos and the upper reaches of a large outflow channel called Ares Vallis.
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESAâ€™s Mars Express spacecraft, show the 'chaotic' terrain of the Aureum Chaos region on Mars.
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
