NASA - National Aeronautics and Space AdministrationPasadena, CA – Late afternoon lighting produced a dramatic shadow of NASA’s Mars Exploration Rover Opportunity photographed by the rover’s rear hazard-avoidance camera on March 20th, 2014.

The shadow falls across a slope called the McClure-Beverlin Escarpment on the western rim of Endeavour Crater, where Opportunity is investigating rock layers for evidence about ancient environments. The scene includes a glimpse into the distance across the 14-mile-wide (22-kilometer-wide) crater.

NASA’s Opportunity Rover continues to explore Mars after a Decade

NASA - National Aeronautics and Space AdministrationPasadena, CA – Eighth graders didn’t have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning’s Channel One news in her Fredericksburg, Texas, classroom caught her eye.

“I wasn’t particularly interested in space at the time,” she recalled last week inside the spacecraft operations facility where she now works at NASA’s Jet Propulsion Laboratory in Pasadena, CA. “I remember I was talking with friends, and out of the corner of my eye I noticed this thing bouncing and rolling on a red surface. I watched as it stopped and opened up, and it had this rover inside.”

NASA's Mars Exploration Rover Opportunity observed this outcrop on the "Murray Ridge" portion of the rim of Endeavour Crater as the rover approached the 10th anniversary of its landing on Mars.

NASA’s Mars Exploration Rover Opportunity starts Solander Point climb

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover has begun climbing “Solander Point,” the northern tip of the tallest hill it has encountered in the mission’s nearly 10 Earth years on Mars.

Guided by mineral mapping from orbit, the rover is exploring outcrops on the northwestern slopes of Solander Point, making its way up the hill much as a field geologist would do. The outcrops are exposed from several feet (about 2 meters) to about 20 feet (6 meters) above the surrounding plains, on slopes as steep as 15 to 20 degrees. The rover may later drive south and ascend farther up the hill, which peaks at about 130 feet (40 meters) above the plains.

NASA’s Opportunity Rover begins work around Solander Point on Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars rover Opportunity is studying the area of contact between a rock layer formed in acidic wet conditions long ago and an even older one that may be from a more neutral wet environment.

This geological contact line recording a change in environmental conditions billions of years ago lies at the foot of a north-facing slope, “Solander Point,” that the rover’s operators chose months ago as Opportunity’s work area for the coming Martian southern hemisphere winter.

This view from NASA's Mars Exploration Rover Opportunity shows an area where a pale-toned geological unit called the "Burns Foundation," in the foreground, abuts a different geological unit. The darker unit, believed to be older, marks the edge of "Solander Point," a raised segment of the western rim of Endeavour Crater. (Image credit: NASA/JPL-Caltech)

NASA’s Mars Exploration Rover is on the move again heading toward Rock Layers

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover Opportunity is trekking to a new study area still many weeks away. Soon the rover will celebrate its 10th Anniversary of leaving Earth.

The destination, called “Solander Point,” offers Opportunity access to a much taller stack of geological layering than the area where the rover has worked for the past 20 months, called “Cape York.” Both areas are raised segments of the western rim of Endeavour Crater, which is about 14 miles (22 kilometers) in diameter.

NASA's Mars Exploration Rover Opportunity used its panoramic camera (Pancam) to acquire this view of "Solander Point" during the mission's 3,325th Martian day, or sol (June 1st, 2013). (Image credit: NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.)

NASA’s Mars Rover Opportunity investigates Rock changed by Water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s senior Mars rover, Opportunity, is driving to a new study area after a dramatic finish to 20 months on “Cape York” with examination of a rock intensely altered by water.

The fractured rock, called “Esperance,” provides evidence about a wet ancient environment possibly favorable for life. The mission’s principal investigator, Steve Squyres of Cornell University, Ithaca, NY, said, “Esperance was so important, we committed several weeks to getting this one measurement of it, even though we knew the clock was ticking.”

The pale rock in the upper center of this image, about the size of a human forearm, includes a target called "Esperance," which was inspected by NASA's Mars Exploration Rover Opportunity. Data from the rover's alpha particle X-ray spectrometer (APXS) indicate that Esperance's composition is higher in aluminum and silica, and lower in calcium and iron, than other rocks Opportunity has examined in more than nine years on Mars. Preliminary interpretation points to clay mineral content due to intensive alteration by water. (Image Credit: NASA/JPL-Caltech/Cornell/Arizona State Univ.)

NASA’s Mars Exploration Rover Opportunity begins 10th year of service

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Exploration Rover Opportunity, one of the twin rovers that bounced to airbag-cushioned safe landings on Mars nine years ago this week, is currently examining veined rocks on the rim of an ancient crater.

Opportunity has driven 22.03 miles (35.46 kilometers) since it landed in the Meridiani Planum region of Mars on January 24th, 2004, PST (January 25th, Universal Time).

As NASA's Mars Exploration Rover Opportunity neared the ninth anniversary of its landing on Mars, the rover was working in the 'Matijevic Hill' area seen in this view from Opportunity's panoramic camera (Pancam). (Image Credit: NASA/JPL-Caltech/Cornell/Arizona State Univ.)

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

 

Written by Guy Webster

NASA - National Aeronautics and Space AdministrationPasadena, 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.

NASA’s Opportunity Rover completes examination of Matijevic Hill on the rim of Mars’ Endeavour Crater

 

Written by Guy Webster

NASA - National Aeronautics and Space AdministrationPasadena, CA – The latest work assignment for NASA’s long-lived Mars rover Opportunity is a further examination of an area where the robot just completed a walkabout.

“If you are a geologist studying a site like this, one of the first things you do is walk the outcrop, and that’s what we’ve done with Opportunity,” said Steve Squyres, the mission’s principal investigator at Cornell University in Ithaca, NY.

NASA’s Mars Curiosity Rover finishes analyzing it’s first Martian Soil Sample

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover.

Detection of the substances during this early phase of the mission demonstrates the laboratory’s capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rover’s instruments.
