Topic: Marathon ValleyWritten by Guy Webster
The rover team plans observations in the valley to determine what type of fluid activity carved it billions of years ago: water, wind, or flowing debris lubricated by water. A color panorama of a ridge called “Rocheport” provides both a parting souvenir of Cape Tribulation and also possible help for understanding the valley ahead. The view was assembled from multiple images taken by Opportunity’s panoramic camera. ![]() A grooved ridge called “Rocheport” on the rim of Mars’ Endeavour Crater spans this scene from the Pancam on NASA’s Mars rover Opportunity.

NASA’s Opportunity Rover to examine Gully on Mars that may have been created by WaterWritten by Guy Webster
The longest-active rover on Mars also will, for the first time, visit the interior of the crater it has worked beside for the last five years. These activities are part of a two-year extended mission that began October 1st, the newest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004. Opportunity launched on July 7th, 2003 and landed on Mars on January 24th, 2004 (PST), on a planned mission of 90 Martian days, which is equivalent to 92.4 Earth days. ![]() This scene from NASA’s Mars rover Opportunity shows “Wharton Ridge,” which forms part of the southern wall of “Marathon Valley” on the rim of Endeavour Crater. The ridge’s name honors the memory of astrobiologist Robert A. Wharton (1951-2012). The scene is presented in approximately true color.

NASA’s Mars Rover Opportunity finishes work at Marathon Valley on MarsWritten by Guy Webster
Opportunity recently collected a sweeping panorama from near the western end of this east-west valley. The vista shows an area where the mission investigated evidence about how water altered the ancient rocks and, beyond that, the wide floor of Endeavour Crater and the crater’s eastern rim about 14 miles (22 kilometers) away. ![]() “Marathon Valley” on Mars opens to a view across Endeavour Crater in this scene from the Pancam of NASA’s Mars rover Opportunity. The scene merges many exposures taken during April and May 2016. The view spans from north (left) to west-southwest. Its foreground shows the valley’s fractured texture.

NASA’s Mars Opportunity rover spots Dust Devil on MarsWritten by DC Agle
Opportunity took the image using its navigation camera (Navcam) on March 31st, 2016, during the 4,332nd Martian day, or sol, of the rover’s work on Mars. ![]() From its perch high on a ridge, NASA’s Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below.

NASA’s Mars Opportunity rover tackles highest angled slope ever attempted on MarsWritten by Guy Webster
A new image shows the view overlooking the valley below and catches the rover’s own shadow and wheel tracks as Opportunity heads toward its next target. ![]() A shadow and tracks of NASA’s Mars rover Opportunity appear in this March 22, 2016, image, which has been rotated 13.5 degrees to adjust for the tilt of the rover.

NASA’s Mars Opportunity Rover travels up steep slope on MarsWritten by Guy Webster
Researchers are using Opportunity this month to examine rocks that may have been chemically altered by water billions of years ago. The mission’s current targets of investigation are from ruddy-tinted swaths the researchers call “red zones,” in contrast to tan bedrock around these zones. The targets lie on “Knudsen Ridge,” atop the southern flank of “Marathon Valley,” which slices through the western rim of Endeavour Crater. ![]() This scene from NASA’s Mars Exploration Rover Opportunity looks upward at “Knudsen Ridge” from the valley below.

NASA’s Mars Opportunity rover keeps busy during Martian WinterWritten by Guy Webster
The modern Mars environment lent a hand, providing wind that removed some dust from Opportunity’s solar panels in the weeks before and after the Mars southern hemisphere’s winter solstice on January 2nd. ![]() The target beneath the tool turret at the end of the rover’s robotic arm in this image from NASA’s Mars Exploration Rover Opportunity is “Private John Potts.” (NASA) «Read the rest of this article» Sections: Sports | No Comments
NASA’s Mars Rover Opportunity to work in Marathon Valley during the Martian WinterWritten by Guy Webster
Marathon Valley slices downhill from west to east for about 300 yards or meters through the western rim of Endeavour Crater. Opportunity has been investigating rock targets in the western portion of the valley since late July, working its way eastward in a thorough reconnaissance of the area. ![]() This Martian scene shows contrasting textures and colors of “Hinners Point,” at the northern edge of “Marathon Valley,” and swirling reddish zones on the valley floor to the left.

NASA’s Mars Rover Opportunity moves towards valley with clay outcropsWritten by Guy Webster
Opportunity resumed driving on June 27th after about three weeks of reduced activity around Mars solar conjuntion, when the sun’s position between Earth and Mars disrupts communication. The rover is operating in a mode that does not store any science data overnight. It transmits the data the same day they’re collected. ![]() Road trip! This compilation of images from hazard-avoidance cameras on NASA’s Mars Exploration Rover Opportunity between January 2004 and April 2015 shows the rover’s-eye-view of the Martian marathon covering 26.2 miles(42.2 kilometers) from its landing location. A map of the rover’s path is on the right. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars rover Opportunity completes Martian Marathon in 11 yearsWritten by Dr. Tony Phillips
On Tuesday, March 24th 2015, NASA’s Mars rover Opportunity completed its first Red Planet marathon– 26.219 miles – with a finish time of roughly 11 years and two months. “This mission isn’t about setting distance records; it’s about making scientific discoveries,” says Steve Squyres, Opportunity principal investigator at Cornell University. “Still, running a marathon on Mars feels pretty cool.” «Read the rest of this article» Sections: Technology | No Comments
