NASA - National Aeronautics and Space AdministrationPasadena, CA – The second bite of a Martian mountain taken by NASA’s Curiosity Mars rover hints at long-ago effects of water that was more acidic than any evidenced in the rover’s first taste of Mount Sharp, a layered rock record of ancient Martian environments.

The rover used a new, low-percussion-level drilling technique to collect sample powder last week from a rock target called “Mojave 2.”

Curiosity reached the base of Mount Sharp five months ago after two years of examining other sites inside Gale Crater and driving toward the mountain at the crater’s center. The first sample of the mountain’s base layer came from a target called “Confidence Hills,” drilled in September.

Gray cuttings from Curiosity's drilling into a target called "Mohave 2" are visible surrounding the sample-collection hole in this Jan. 31, 2015, image from the rover's MAHLI camera. This site in the "Pahrump Hills" outcrop provided the mission's second drilled sample of Mars' Mount Sharp. (NASA/JPL-Caltech/MSSS)

NASA’s Mars Curiosity Rover set to drill into Mineral Crystal Rock on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A rock target where NASA’s Curiosity Mars rover is using its sample-collection drill this week may have a salty story to tell.

This target, called “Mojave,” displays copious slender features, slightly smaller than grains of rice, that appear to be mineral crystals. A chance to learn their composition prompted the Curiosity science team to choose Mojave as the next rock-drilling target for the 29-month-old mission investigating Mars’ Gale Crater. The features might be a salt mineral left behind when lakewater evaporated.

This week, Curiosity is beginning a “mini-drill” test to assess the rock’s suitability for deeper drilling, which collects a sample for onboard laboratory analysis.

This view from the wide-angle Hazard Avoidance Camera on the front of NASA's Curiosity Mars Rover shows the rover's drill in position for a mini-drill test to assess whether a rock target called "Mojave" is appropriate for full-depth drilling to collect a sample. (NASA/JPL-Caltech)

NASA’s Mars Curiosity Rover discovers sediment deposits in Martian Lake Bed

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Observations by NASA’s Curiosity Rover indicate Mars’ Mount Sharp was built by sediments deposited in a large lake bed over tens of millions of years.

This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet.

“If our hypothesis for Mount Sharp holds up, it challenges the notion that warm and wet conditions were transient, local, or only underground on Mars,” said Ashwin Vasavada, Curiosity deputy project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. “A more radical explanation is that Mars’ ancient, thicker atmosphere raised temperatures above freezing globally, but so far we don’t know how the atmosphere did that.”

NASA reports Mars Curiosity rover will not drill rock “Bonanza King” because of instablity

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Evaluation of a pale, flat Martian rock as the potential next drilling target for NASA’s Curiosity Mars rover determined that the rock was not stable enough for safe drilling.

The rock, called “Bonanza King,” moved slightly during the mini-drill activity on Wednesday, at an early stage of this test, when the percussion drill impacted the rock a few times to make an indentation.

This image from the front Hazcam on NASA's Curiosity Mars rover shows the rover's drill in place during a test of whether the rock beneath it, "Bonanza King," would be an acceptable target for drilling to collect a sample. Subsequent analysis showed the rock budged during the Aug. 19, 2014, test. (NASA/JPL-Caltech)

NASA’s Jet Propulsion Laboratory

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’s Mars Curiosity rover captures images of the planet Mercury passing in front of the Sun

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has imaged the planet Mercury passing in front of the sun, visible as a faint darkening that moves across the face of the sun.

This is the first transit of the sun by a planet observed from any planet other than Earth, and also the first imaging of Mercury from Mars.

Mercury fills only about one-sixth of one pixel as seen from such great distance, so the darkening does not have a distinct shape, but its position follows Mercury’s expected path based on orbital calculations.

NASA’s Curiosity Mars rover completes work at waypoint “The Kimberley”; ready to move to next destination

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Portions of powdered rock collected by drilling into a sandstone target last week have been delivered to laboratory instruments inside NASA’s Curiosity Mars rover, and the rover will soon drive on toward its long-term destination on a mountain slope.

Other instruments on the rover have inspected the rock’s interior exposed in the hole and in drill cuttings heaped around the hole. The target rock, “Windjana,” is a sandstone slab within a science waypoint area called “The Kimberley.”

The Mars Hand Lens Imager on NASA's Curiosity Mars rover provided this nighttime view of a hole produced by the rover's drill and, inside the hole, a line of scars produced by the rover's rock-zapping laser. The camera used its own white-light LEDs to illuminate the scene on May 13, 2014. (NASA/JPL-Caltech/MSSS)
