“This final panorama embodies what made our Opportunity rover such a remarkable mission of exploration and discovery,” said Opportunity project manager John Callas of NASA’s Jet Propulsion Laboratory in Pasadena, California. ![]() This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover’s Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see. (NASA/JPL-Caltech/Cornell/ASU) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Opportunity Mars Rover Mission EndsNASA Headquarters
The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover’s final communication was received June 10th. ![]() The dramatic image of NASA’s Mars Exploration Rover Opportunity’s shadow was taken on sol 180 (July 26, 2004), by the rover’s front hazard-avoidance camera as the rover moved farther into Endurance Crater in the Meridiani Planum region of Mars.

NASA’s Opportunity Rover has been on Mars for 15 YearsNASA Jet Propulsion Laboratory
The golf-cart-sized rover was designed to travel 1,100 yards (1,006 meters) and operate on the Red Planet for 90 Martian days (sols). It has traveled over 28 miles (45 kilometers) and logged its 5,000th Martian day (or sol) back in February of 2018. ![]() An artist’s concept portrays the NASA Mars Opportunity Rover on the surface of Mars.

NASA explains How a Tiny Curiosity Motor Identified a Massive Martian Dust StormWritten by Lonnie Shekhtman
NASA’s Mars Reconnaissance Orbiter (MRO) provided the earliest insights on May 30th when it observed an accumulation of dust in the atmosphere near Perseverance Valley, where NASA’s Opportunity rover is exploring. ![]() Globes from May 28th and July 1st show a global dust storm completely obscuring the surface of Mars.

Mars Dust Storms begin to dissipate around NASA’s Opportunity RoverNASA’s Jet Propulsion Laboratory
With clearing skies over Opportunity’s resting spot in Mars’ Perseverance Valley, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, believe the nearly 15-year-old, solar-powered rover will soon receive enough sunlight to automatically initiate recovery procedures — if the rover is able to do so. To prepare, the Opportunity mission team has developed a two-step plan to provide the highest probability of successfully communicating with the rover and bringing it back online. ![]() About 11 months before the current dust storm enveloped the rover, Opportunity took five images that were turned into a mosaic showing a view from inside the upper end of “Perseverance Valley” on the inner slope of Endeavour Crater’s western rim. The images were taken on July 7th, 2017. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Opportunity rover waits out Dust StormNASA’s Jet Propulsion Laboratory
NASA’s Mars Reconnaissance Orbiter first detected the storm on Friday, June 1st, 2018. As soon as the orbiter team saw how close the storm was to Opportunity, they notified the rover’s team to begin preparing contingency plans. In a matter of days, the storm had ballooned. ![]() This global map of Mars shows a growing dust storm as of June 6, 2018. The map was produced by the Mars Color Imager (MARCI) camera on NASA’s Mars Reconnaissance Orbiter spacecraft. The blue dot indicates the approximate location of Opportunity.

NASA’s Mars Rover Opportunity makes 5,000th Martian DawnNASA Headquarters
“Five thousand sols after the start of our 90-sol mission, this amazing rover is still showing us surprises on Mars,” said Opportunity Project Manager John Callas, of NASA’s Jet Propulsion Laboratory, Pasadena, California. ![]() NASA’s Mars Exploration Rover Opportunity recorded the dawn of the rover’s 4,999th Martian day, or sol, with its Panoramic Camera (Pancam) on Feb. 15, 2018, yielding this processed, approximately true-color scene.

NASA’s Mars Exploration Rover Opportunity continues to make discoveries on MarsNASA Headquarters
The ground texture seen in recent images from the rover resembles a smudged version of very distinctive stone stripes on some mountain slopes on Earth that result from repeated cycles of freezing and thawing of wet soil. But it might also be due to wind, downhill transport, other processes or a combination. ![]() Textured rows on the ground in this portion of “Perseverance Valley” are under investigation by NASA’s Mars Exploration Rover Opportunity, which used its Navigation Camera to take the component images of this downhill-looking scene. The rover reaches its 5,000th Martian day, or sol, on Feb. 16, 2018. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA Mars Opportunity Rover makes it through another Martian WinterWritten by Guy Webster
Before dust season will come the 14th Earth-year anniversaries of Mars landings by the twin rovers Spirit and Opportunity in January 2004. Their missions were scheduled to last 90 Martian days, or sols, equivalent to about three months. ![]() This enhanced-color view of ground sloping downward to the right in “Perseverance Valley” shows textures that may be due to abrasion by wind-driven sand. The Pancam on NASA’s Mars rover Opportunity’s imaged this scene in October 2017.

NASA’s Mars Rover Opportunity takes panoramic photo from Perseverance ValleyWritten by Guy Webster
The scene includes a broad notch in the crest of the crater’s rim, which may have been a spillway where water or ice or wind flowed over the rim and into the crater. Wheel tracks visible in the area of the notch were left by Opportunity as the rover studied the ground there and took images into the valley below for use in planning its route. ![]() This June 2017 view from the Pancam on NASA’s Opportunity Mars rover shows the area just above “Perseverance Valley” on a large crater’s rim. A broad notch in the crest of the rim, at right, might have been a spillway for a fluid that carved the valley, out of sight on the other side of the rim.
