NASA Mars Curiosity Rover completes drilling it’s Second Rock on Mars

Pasadena, CA – NASA’s Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called “Cumberland.”

Plans call for delivering portions of the sample in coming days to laboratory instruments inside the rover. This is only the second time that a sample has been collected from inside a rock on Mars. The first was Curiosity’s drilling at a target called “John Klein” three months ago. Cumberland resembles John Klein and lies about nine feet (2.75 meters) farther west. Both are within a shallow depression called “Yellowknife Bay.”

NASA’s Mars rover Curiosity drilled into this rock target, “Cumberland,” during the 279th Martian day, or sol, of the rover’s work on Mars (May 19, 2013) and collected a powdered sample of material from the rock’s interior. Analysis of the Cumberland sample using laboratory instruments inside Curiosity will check results from “John Klein,” the first rock on Mars from which a sample was ever collected and analyzed.

NASA’s Mars Curiosity Rover sets course towards Second Rock Targeted for Drilling on Mars

Pasadena, CA – The team operating NASA’s Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.

This second drilling target, called “Cumberland,” lies about nine feet (2.75 meters) west of the rock where Curiosity’s drill first touched Martian stone in February. Curiosity took the first rock sample ever collected on Mars from that rock, called “John Klein.”

This map shows the location of “Cumberland,” the second rock-drilling target for NASA’s Mars rover Curiosity, in relation to the rover’s first drilling target, “John Klein,” within the southwestern lobe of a shallow depression called “Yellowknife Bay.” Cumberland, like John Klein, is a patch of flat-lying bedrock with pale veins and bumpy surface texture. The bumpiness is due to erosion-resistant nodules within the rock, which have been identified as concretions resulting from the action of mineral-laden water.

NASA’s Mars Curiosity rover back to full operation after computer glitch

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

Pasadena, CA – NASA’s Mars rover Curiosity has resumed science investigations after recovery from a computer glitch that prompted the engineers to switch the rover to a redundant main computer on February 28th.

The rover has been monitoring the weather since March 21st and delivered a new portion of powdered-rock sample for laboratory analysis on March 23rd, among other activities.

This view of Curiosity’s left-front and left-center wheels and of marks made by wheels on the ground in the “Yellowknife Bay” area comes from one of six cameras used on Mars for the first time more than six months after the rover landed. The left Navigation Camera (Navcam) linked to Curiosity’s B-side computer took this image during the 223rd Martian day, or sol, of Curiosity’s work on Mars (March 22, 2013). The wheels are 20 inches (50 centimeters) in diameter. (Image credit: NASA/JPL-Caltech)

NASA’s Mars rover Curiosity sees evidence that conditions favorable for Microbial Life extends beyond current location

The Woodlands, TX – NASA’s Mars rover Curiosity has seen evidence of water-bearing minerals in rocks near where it had already found clay minerals inside a drilled rock.

Last week, the rover’s science team announced that analysis of powder from a drilled mudstone rock on Mars indicates past environmental conditions that were favorable for microbial life. Additional findings presented March 18th at a news briefing at the Lunar and Planetary Science Conference in The Woodlands, Texas, suggest those conditions extended beyond the site of the drilling.

NASA’s Mars rover Curiosity takes Panorama of Mount Sharp

Pasadena, CA – Rising above the present location of NASA’s Mars rover Curiosity, higher than any mountain in the 48 contiguous states of the United States, Mount Sharp is featured in new imagery from the rover.

A pair of mosaics assembled from dozens of telephoto images shows Mount Sharp in dramatic detail. The component images were taken by the 100-millimeter-focal-length telephoto lens camera mounted on the right side of Curiosity’s remote sensing mast, during the 45th Martian day of the rover’s mission on Mars (September 20th, 2012).

This mosaic of images from the Mast Camera (Mastcam) on NASA’s Mars rover Curiosity shows Mount Sharp in a white-balanced color adjustment that makes the sky look overly blue but shows the terrain as if under Earth-like lighting.

NASA’s Curiosity rover analysis of rock sample reveals Mars at one time could have supported Life

March 13, 2013 |

Written by Dr. Tony Phillips
Science at NASA

Washington, D.C. – An analysis of a rock sample recently collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.

“A fundamental question for this mission is whether Mars could have supported a habitable environment,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at the agency’s headquarters in Washington. “From what we know now, the answer is yes.”

These fine-grained sediments, likely deposited under water, suggest that Mars could have supported ancient microbial life. Data gathered by Curiosity indicate a habitable environment characterized by neutral pH, chemical gradients that would have created energy for microbes, and a distinctly low salinity, which would have helped metabolism if microorganisms had ever been present.

NASA’s Mars rover Curiosity moves closer to Martian Rock selected for first Drilling

Written by Guy Webster

Pasadena, CA – NASA’s Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers’ approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.

The size of a car, Curiosity is inside Mars’ Gale Crater investigating whether the planet ever offered an environment favorable for microbial life. Curiosity landed in the crater five months ago to begin its two-year prime mission.

NASA’s Mars Curiosity rover uses it’s Dust Removal Tool for the first time to clean a patch of rock

Pasadena, CA – NASA’s Mars rover Curiosity has completed first-time use of a brush it carries to sweep dust off rocks.

Nearing the end of a series of first-time uses of the rover’s tools, the mission has cleared dust away from a targeted patch on a flat Martian rock using the Dust Removal Tool.

The tool is a motorized, wire-bristle brush designed to prepare selected rock surfaces for enhanced inspection by the rover’s science instruments. It is built into the turret at the end of the rover’s arm.

Pasadena, CA – After imaging during the holidays, NASA’s Mars rover Curiosity resumed driving January 3rd and pulled within arm’s reach of a sinuous rock feature called “Snake River.”

Snake River is a thin curving line of darker rock cutting through flatter rocks and jutting above sand. Curiosity’s science team plans to get a closer look at it before proceeding to other nearby rocks.

The sinuous rock feature in the lower center of this mosaic of images recorded by the NASA Mars rover Curiosity is called “Snake River.” The images in the mosaic were taken by Curiosity’s Navigation Camera during the 133rd Martian day, or sol, of the rover’s mission on Mars (Dec. 20th, 2012).

NASA’s Mars rover Curiosity to drill rock in ditch on Mars named Yellowknife Bay

Pasadena, CA – The NASA Mars rover Curiosity this week is driving within a shallow depression called “Yellowknife Bay,” providing information to help researchers choose a rock to drill.

Using Curiosity’s percussive drill to collect a sample from the interior of a rock, a feat never before attempted on Mars, is the mission’s priority for early 2013. After the powdered-rock sample is sieved and portioned by a sample-processing mechanism on the rover’s arm, it will be analyzed by instruments inside Curiosity.
