NASA’s Mars Curiosity rover to analysis select rocks at Mount Sharp

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has completed a reconnaissance “walkabout” of the first outcrop it reached at the base of the mission’s destination mountain and has begun a second pass examining selected rocks in the outcrop in more detail.

Exposed layers on the lower portion of Mount Sharp are expected to hold evidence about dramatic changes in the environmental evolution of Mars. That was a major reason NASA chose this area of Mars for this mission.

The lowermost of these slices of time ascending the mountain includes a pale outcrop called “Pahrump Hills.”

NASA - National Aeronautics and Space AdministrationPasadena, CA – Reddish rock powder from the first hole drilled into a Martian mountain by NASA’s Curiosity rover has yielded the mission’s first confirmation of a mineral mapped from orbit.

“This connects us with the mineral identifications from orbit, which can now help guide our investigations as we climb the slope and test hypotheses derived from the orbital mapping,” said Curiosity Project Scientist John Grotzinger, of the California Institute of Technology in Pasadena.

NASA’s Mars Curiosity rover takes first drill sample from Mount Sharp

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has collected its first taste of the layered mountain whose scientific allure drew the mission to choose this part of Mars as a landing site.

Late Wednesday, September 24th, the rover’s hammering drill chewed about 2.6 inches (6.7 centimeters) deep into a basal-layer outcrop on Mount Sharp and collected a powdered-rock sample. Data and images received early Thursday at NASA’s Jet Propulsion Laboratory, Pasadena, California, confirmed success of this operation. The powder collected by the drilling is temporarily held within the sample-handling mechanism on the rover’s arm.

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination.

“Curiosity now will begin a new chapter from an already outstanding introduction to the world,” said Jim Green, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “After a historic and innovative landing along with its successful science discoveries, the scientific sequel is upon us.”

NASA’s Curiosity Mars rover gets ready to drill it’s fourth rock on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team operating NASA’s Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission’s fourth drilling target, if it passes engineers’ evaluation.

They call it “Bonanza King.”

It is not at the “Pahrump Hills” site the team anticipated the rover might reach by mid-August. Unexpected challenges while driving in sand prompted the mission to reverse course last week after entering a valley where ripples of sand fill the floor and extend onto sloping margins.

In this image from NASA's Curiosity Mars rover looking up the ramp at the northeastern end of "Hidden Valley," a pale outcrop including drilling target "Bonanza King" is at the center of the scene. (NASA/JPL-Caltech)

NASA’s Curiosity Mars Rover finishes second year on the Red Planet

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s most advanced roving laboratory on Mars celebrates its second anniversary since landing inside the Red Planet’s Gale Crater on August 5th, 2012, PDT (August 6th, 2012, EDT).

During its first year of operations, the Curiosity rover fulfilled its major science goal of determining whether Mars ever offered environmental conditions favorable for microbial life.

Clay-bearing sedimentary rocks on the crater floor in an area called Yellowknife Bay yielded evidence of a lake bed environment billions of years ago that offered fresh water, all of the key elemental ingredients for life, and a chemical source of energy for microbes, if any existed there.

This image from the Navigation Camera on NASA's Curiosity Mars rover shows wheel tracks printed by the rover as it drove on the sandy floor of a lowland called "Hidden Valley" on the route toward Mount Sharp. The image was taken on Aug. 4, 2014.

NASA’s Mars Curiosity rover moves toward bedrock outcrop at Mount Sharp

NASA - National Aeronautics and Space AdministrationPasadena, CA – As it approaches the second anniversary of its landing on Mars, NASA’s Curiosity rover is also approaching its first close look at bedrock that is part of Mount Sharp, the layered mountain in the middle of Mars’ Gale Crater.

The mission made important discoveries during its first year by finding evidence of ancient lake and river environments. During its second year, it has been driving toward long-term science destinations on lower slopes of Mount Sharp.

This full-circle panorama of the landscape surrounding NASA's Curiosity Mars rover on July 31, 2014, offers a view into sandy lower terrain called "Hidden Valley," which is on the planned route ahead. It combines several images from Curiosity's Navigation Camera. South is at the center. (NASA/JPL-Caltech)

NASA’s Curiosity Rover completes first Martian Year on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover will complete a Martian year — 687 Earth days — on June 24th, having accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life.

One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms.

NASA's Curiosity Mars rover used the camera at the end of its arm in April and May 2014 to take dozens of component images combined into this self-portrait where the rover drilled into a sandstone target called "Windjana." (NASA/JPL-Caltech/MSSS)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Portions of rock powder collected by the hammering drill on NASA’s Curiosity Mars rover from a slab of Martian sandstone will be delivered to the rover’s internal instruments.

Rover team members at NASA’s Jet Propulsion Laboratory, Pasadena, CA, received confirmation early today (Tuesday) of Curiosity’s third successful acquisition of a drilled rock sample, following the drilling Monday evening (PDT).

This May 5, 2014, image from the Navigation Camera on NASA's Curiosity Mars rover shows two holes at top center drilled into a sandstone target called "Windjana." The farther hole was created by the rover's drill while it collected rock-powder sample material from the interior of the rock.

NASA’s Curiosity Mars rover searches for next spot to drill

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team operating NASA’s Curiosity Mars rover is telling the rover to use several tools this weekend to inspect a sandstone slab being evaluated as a possible drilling target.

If this target meets criteria set by engineers and scientists, it could become the mission’s third drilled rock, and the first that is not mudstone. The team calls it “Windjana,” after a gorge in Western Australia.

NASA's Curiosity Mars rover has driven within robotic-arm's reach of the sandstone slab at the center of this April 23 view from the rover's Mast Camera. The rover team plans to have Curiosity examine a target patch on the rock, called "Windjana," to aid a decision about whether to drill there. (NASA/JPL-Caltech/MSSS)
