Mars: Prospecting from Orbit

The multiple of morphological and topographic information from stereo images from NASA’s Mars Reconnaissance Orbiter, as good as compositional information from near-infrared spectroscopy has been proven to be a absolute apparatus for bargain a geology of Mars.

Beginning with a OMEGA instrument on a European Space Agency’s Mars Express orbiter in 2003, a aspect of Mars has been examined during near-infrared wavelengths by imaging spectrometers that are able of detecting specific minerals and mapping their spatial extent. The CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) instrument on a orbiter is a visible/near-infrared imaging spectrometer, and a HiRISE camera works together with it to request a coming of vegetable deposits rescued by this orbital prospecting.

Mawrth Vallis is one of a regions on Mars that has captivated most courtesy since of a inlet and farrago of a minerals identified by these spectrometers. It is a large, ancient outflow channel on a domain of a Southern highlands and Northern lowlands. Both a OMEGA and CRISM instruments have rescued clay minerals here that contingency have been deposited in a water-rich environment, substantially some-more than 4 billion years ago. For this reason, Mawrth Vallis is one of a dual claimant alighting sites for a destiny Mars Express Rover Mission designed by a European Space Agency.

This picture was targeted on a plcae where a CRISM instrument rescued a specific vegetable called alunite, KAl3(SO4)2(OH)6. Alunite is a hydrated aluminum potassium sulfate, a vegetable that is important since it contingency have been deposited in a soppy acidic environment, abounding in sulfuric acid. Our picture shows that a deposition is splendid and colorful, and extensively fractured. The breadth of a cutout is 1.2 kilometers.

The University of Arizona, Tucson, operates HiRISE, that was built by Ball Aerospace Technologies Corp., Boulder, Colo. NASA’s Jet Propulsion Laboratory, a multiplication of Caltech in Pasadena, California, manages a Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.
