NASA Rover Drill Pulls First Taste From Mars Mountain

First Sampling Hole in Mount Sharp



This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows the first sample-collection hole drilled in Mount Sharp, the layered mountain that is the science destination of the rover's extended mission.


The hole is 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.7 centimeters) deep, at a target called "Confidence Hills" on the "Pahrump Hills" outcrop at the base of the mountain.


This is a merged-focus image product combining information from multiple images that MAHLI took from a position 2 inches (5 centimeters) away from the target. The images were taken on Sept. 24, 2014, during the 759th Martian day, or sol, of Curiosity's work on Mars.

MAHLI was built by Malin Space Science Systems, San Diego. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover.

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, Sept. 24, 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.

"This drilling target is at the lowest part of the base layer of the mountain, and from here we plan to examine the higher, younger layers exposed in the nearby hills," said Curiosity Deputy Project Scientist Ashwin Vasavada of JPL. "This first look at rocks we believe to underlie Mount Sharp is exciting because it will begin to form a picture of the environment at the time the mountain formed, and what led to its growth."

Curiosity Mars Rover's Approach to 'Pahrump Hills'

This southeastward-looking vista from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows the "Pahrump Hills" outcrop and surrounding terrain seen from a position about 70 feet (20 meters) northwest of the outcrop.

The component images were acquired on Sept. 17, 2014, during the 751st Martian day, or sol, of Curiosity's work on Mars. The rover team used these images to select a first drilling site on Pahrump Hills, which is part of the base layer of Mount Sharp. The selected drilling location is in the near portion of the pale outcrop to the right of the sand ripples.

The scene includes four distinct features:


1) Sand ripples in foreground, typical of those along the floors of valleys in this area within Gale Crater


2) The Pahrump Hills section of the Murray formation, where approximately 60 vertical feet (18 meters) of rock layers are exposed


3) A darker ridge off in the distance toward the left


4) Northwestern slopes of Mount Sharp in the background, where an abrupt transition is apparent between the buttes and valleys in the lower part and the tilted and carved beds of the upper part

This view combines several exposures taken by the Mastcam's left-eye camera. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth.

After landing on Mars in August 2012 but before beginning the drive toward Mount Sharp, Curiosity spent much of the mission's first year productively studying an area much closer to the landing site, but in the opposite direction. The mission accomplished its science goals in that Yellowknife Bay area. Analysis of drilled rocks there disclosed an ancient lakebed environment that, more than three billion years ago, offered ingredients and a chemical energy gradient favorable for microbes, if any existed there.

From Yellowknife Bay to the base of Mount Sharp, Curiosity drove more than 5 miles (8 kilometers) in about 15 months, with pauses at a few science waypoints. The emphasis in mission operations has now changed from drive, drive, drive to systematic layer-by-layer investigation.

"We're putting on the brakes to study this amazing mountain," said Curiosity Deputy Project Manager Jennifer Trosper of JPL. "Curiosity flew hundreds of millions of miles to do this."


Curiosity arrived Sept. 19 at an outcrop called "Pahrump Hills," which is a section of the mountain's basal geological unit, called the Murray formation. Three days later, the rover completed a "mini-drill" procedure at the selected drilling target, "Confidence Hills," to assess the target rock's suitability for drilling. A mini-drill activity last month determined that a rock slab under consideration then was not stable enough for full drilling, but Confidence Hills passed this test.


The rock is softer than any of the previous three targets where Curiosity has collected a drilled sample for analysis.

Between the mini-drill test and the sample-collection drilling, researchers used tools on Curiosity's mast and robotic arm for close-up inspection of geometrically distinctive features on the nearby surface of the rock.


These features on the Murray formation mudstones are the accumulations of resistant materials. They occur both as discrete clusters and as dendrites, where forms are arranged in tree-like branching. By investigating the shapes and chemical ingredients in these features, the team hopes to gain information about the possible composition of fluids at this Martian location long ago.


The next step will be to deliver the rock-powder sample into a scoop on the rover's arm. In the open scoop, the powder's texture can be observed for an assessment of whether it is safe for further sieving, portioning and delivery into Curiosity's internal laboratory instruments without clogging hardware. The instruments can perform many types of analysis to identify chemistry and mineralogy of the source rock.

NASA's Mars Science Laboratory Project is using Curiosity to assess ancient habitable environments and major changes in Martian environmental conditions. JPL, a division of Caltech, built the rover and manages the project for NASA's Science Mission Directorate in Washington.

Resistant Features in 'Pahrump Hills' Outcrop

This image from the Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity Mars rover shows an example of a type of geometrically distinctive feature that researchers are examining at a mudstone outcrop at the base of Mount Sharp.

These features on the "Pahrump Hills" outcrop are accumulations of erosion-resistant materials. Similar-appearing features on Earth form when shallow bodies of water begin to evaporate and minerals precipitate from the concentrated brines.

The width of the image covers about nine-tenths of an inch (2.2 centimeters) of the rock surface. This is a merged-focus image product combining information from multiple MAHLI images taken on Sept. 23, 2014, during the 758th Martian day, or sol, of Curiosity's work on Mars.

MAHLI was built by Malin Space Science Systems, San Diego.

Excellent Post, thank you for sharing.

The most expensive hammer drill ever!

Now, who's paying for the plug and the screw?:Biggrin2:
