Mars Exploration Rovers

Post by Christopher K. » October 19th, 2014, 3:07 pm

The Mars Exploration Rovers, Opportunity and Spirit, may get a chance to study the pass by Mars of Comet Siding Spring. If they do, the results may be posted at...

Opportunity and Spirit went into "overtime" (past their scheduled life of research) in April 2004:

25 January was the tenth anniversary of Opportunity's landing; in that decade it travelled almost forty kilometers. That day's APOD was a self-portrait taken by Opportunity earlier in January.

In two images taken twelve Sols apart, a rock appeared where it had not been before. Probably spat or knocked there by one of Opportunity's wheels, it certainly looked different from the surrounding rocks.

Tomorrow is the twelfth anniversary of the landing of the rover Spirit. As shown in the fifty-second video "Spirit's Last Moves Before Winter", the intrepid machine sank into dirt from which it could not escape.

Opportunity is in sleep mode at this time; the massive global dust storm hindering views of the Red Planet is also keeping Opportunity from acquiring enough sunlight for its panels.

NASA's Record-Setting Opportunity Rover Mission on Mars Comes to End

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.

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 10.

"It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars," said NASA Administrator Jim Bridenstine. "And when that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration."

Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.
