After collecting drilled stone powder in arguably a many scenic landscape nonetheless visited by a Mars rover, NASA’s Curiosity mobile laboratory is pushing toward ascending destinations as partial of a two-year idea prolongation that commenced Oct. 1.

The destinations embody a shallow capped with element abounding in a iron-oxide vegetable hematite, about a mile-and-a-half (two-and-a-half kilometers) ahead, and an bearing of clay-rich bedrock over that.

These are pivotal scrutiny sites on reduce Mount Sharp, that is a layered, Mount-Rainier-size pile where Curiosity is questioning justification of ancient, water-rich environments that contrariety with a harsh, dry conditions on a aspect of Mars today.

“We continue to strech aloft and younger layers on Mount Sharp,” pronounced Curiosity Project Scientist Ashwin Vasavada, of NASA’s Jet Propulsion Laboratory, Pasadena, California. “Even after 4 years of exploring nearby and on a mountain, it still has a intensity to totally warn us.”

Hundreds of photos Curiosity took in new weeks amid a cluster of mesas and buttes of opposite shapes are uninformed highlights among a some-more than 180,000 images a corsair has taken given alighting on Mars in Aug 2012. Newly accessible vistas embody a rover’s latest self-portrait from a tone camera during a finish of a arm and a scenic scenery from a tone camera during a tip of a mast.

“Bidding good-bye to ‘Murray Buttes,’ Curiosity’s assignment is a ongoing investigate of ancient habitability and a intensity for life,” pronounced Curiosity Program Scientist Michael Meyer during NASA Headquarters, Washington. “This mission, as it explores a period of stone layers, is reading a ‘pages’ of Martian history—changing a bargain of Mars and how a world has evolved. Curiosity has been and will be a cornerstone in a skeleton for destiny missions.”

The member images of a self-portrait were taken nearby a bottom of one of a Murray Buttes, during a same site where a corsair used a cavalcade on Sept. 18 to acquire a representation of stone powder. An try to cavalcade during this site 4 days progressing had halted betimes due to a short-circuit emanate that Curiosity had gifted previously, though a second try successfully reached full abyss and collected representation material. After vacating a buttes area, Curiosity delivered some of a stone representation to a inner laboratory for analysis.

This latest cavalcade site—the 14th for Curiosity—is in a geological covering about 600 feet (180 meters) thick, called a Murray formation. Curiosity has climbed scarcely half of this formation’s density so distant and found it consists essentially of mudstone, shaped from sand that amassed during a bottom of ancient lakes. The commentary prove that a lake sourroundings was enduring, not fleeting. For roughly a initial half of a new two-year idea extension, a corsair group anticipates questioning a top half of a Murray formation.

“We will see possibly that record of lakes continues further,” Vasavada said. “The some-more straight density we see, a longer a lakes were present, and a longer habitable conditions existed here. Did a ancient sourroundings change over time? Will a form of justification we’ve found so distant transition to something else?”

The “Hematite Unit” and “Clay Unit” above a Murray arrangement were identified from Mars orbiter observations before Curiosity’s landing. Information about their composition, from a Compact Reconnaissance Imaging Spectrometer aboard NASA’s Mars Reconnaissance Orbiter, done them high priorities as destinations for a corsair mission. Both hematite and clay typically form in soppy environments.

Vasavada said, “The Hematite and a Clay units expected prove opposite environments from a conditions available in comparison stone underneath them and opposite from any other. It will be engaging to see possibly either or both were habitable environments.”

NASA authorized Curiosity’s second extended idea this summer on a basement of skeleton presented by a corsair team. Additional extensions for exploring over adult Mount Sharp might be deliberate in a future. The Curiosity idea has already achieved a categorical idea of last possibly a alighting segment ever offering environmental conditions that would have been auspicious for microbial life, if Mars has ever hosted life. The idea found justification of ancient rivers and lakes, with a chemical appetite source and all of a chemical mixture required for life as we know it.
