Members of NASA's Mars 2020 project install the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) into the chassis of NASA's next Mars rover. MOXIE will demonstrate a way that future explorers might produce oxygen from the Martian atmosphere for propellant and for breathing. The car-battery-sized instrument does this by collecting carbon dioxide (CO2) from the Martian atmosphere and electrochemically splitting the carbon dioxide molecules into oxygen and carbon monoxide molecules. The oxygen is then analyzed for purity before being vented back out to the Martian atmosphere along with the carbon monoxide and other exhaust products. The image was taken on March 20, 2019, in the Spacecraft Assembly Facility's High Bay 1 Cleanroom at NASA's Jet Propulsion Laboratory, in Pasadena, California. https://photojournal.jpl.nasa.gov/catalog/PIA23154

This view of a test rover at NASA's Jet Propulsion Laboratory, Pasadena, California, results from advance testing of arm positions and camera pointings for taking a low-angle self-portrait of NASA's Curiosity Mars rover. This rehearsal in California led to a dramatic Aug. 5, 2015, selfie of Curiosity, online at PIA19807. Curiosity's arm-mounted Mars Hand Lens Imager (MAHLI) camera took 92 of component images that were assembled into that mosaic. The rover team positioned the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity. This practice version was taken at JPL's Mars Yard in July 2013, using the Vehicle System Test Bed (VSTB) rover, which has a test copy of MAHLI on its robotic arm. MAHLI was built by Malin Space Science Systems, San Diego.

"Marathon Valley" on Mars opens northeastward to a view across the floor of Endeavour Crater in this scene from the panoramic camera (Pancam) of NASA's Mars Exploration Rover Opportunity. The scene merges multiple Pancam exposures taken during the period April 16 through May 15, 2016, corresponding to sols (Martian days) 4,347 through 4,375 of Opportunity's work on Mars. It spans from north, at the left, to west-southwest, at the right. The high point in the right half of the scene is "Knudsen Ridge," which forms part of the southern edge of Marathon Valley. Portions of the northeastern and eastern rim of Endeavour crater appear on the distant horizon. Endeavour Crater is 14 miles (22 kilometers) in diameter. The fractured texture of Marathon Valley's floor is visible in the foreground. The view merges exposures taken through three of the Pancam's color filters, centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet). It is presented in approximately true color. The rover team calls this image the mission's "Sacagawea Panorama," for the Lemhi Shoshone woman, also commemorated on U.S. dollar coins, whose assistance to the Lewis and Clark expedition helped enable its successes in 1804-1806. Many rocks and other features in Marathon Valley were informally named for members of Lewis and Clark's "Corps of Discovery" expedition. Opportunity entered Marathon Valley in July 2015. The valley's informal name was chosen because Opportunity's arrival at this point along the western rim of Endeavour Crater coincided closely with the rover surpassing marathon-footrace distance in its total driving odometry since landing on Mars in January 2004. The team's planned investigations in the valley were nearing completion when the component images for this scene were taken. http://photojournal.jpl.nasa.gov/catalog/PIA20749

This view of a small, relatively fresh crater on Mars combines images from the left eye and right eye of the Panoramic Camera (Pancam) on NASA's Opportunity Mars rover, to appear three-dimensional when seen through blue-red glasses with the red lens on the left. The rover paused beside the crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call it "Orion Crater," after the Apollo 16 lunar module. The crater's diameter is about 90 feet (27 meters). From the small amount of erosion or filling that Orion Crater has experienced, its age is estimated at no more than 10 million years. It lies on the western rim of Endeavour Crater. For comparison, Endeavor is about 14 miles (22 kilometers) in diameter and more than 3.6 billion years old. The component images were taken on April 26, 2017, during the 4,712th Martian day, or sol, of Opportunity's work on Mars. Apollo 16 astronauts John Young and Charles Duke flew in the Orion lunar module to and from the first human landing in the lunar highlands while Ken Mattingly orbited the moon in the command module, Casper. On the moon, Young and Duke investigated Plum Crater, which is approximately the same size as Mars' Orion Crater. https://photojournal.jpl.nasa.gov/catalog/PIA21706

"Marathon Valley" on Mars opens northeastward in this stereo scene from the panoramic camera (Pancam) of NASA's Mars Exploration Rover Opportunity. The image combines views from the left eye and right eye of the Pancam to appear three-dimensional when seen through blue-red glasses with the red lens on the left. The component images were taken during the period April 16 through May 15, 2016, corresponding to sols (Martian days) 4,347 through 4,375 of Opportunity's work on Mars. The vista spans from north, at the left, to west-southwest, at the right. The high point in the right half of the scene is "Knudsen Ridge," which forms part of the southern edge of Marathon Valley. The fractured texture of Marathon Valley's floor is visible in the foreground. The rover team calls this image the mission's "Sacagawea Panorama," for the Lemhi Shoshone woman, also commemorated on U.S. dollar coins, whose assistance to the Lewis and Clark expedition helped enable its successes in 1804-1806. Many rocks and other features in Marathon Valley were informally named for members of Lewis and Clark's "Corps of Discovery" expedition. Opportunity entered Marathon Valley in July 2015. The valley's informal name was chosen because Opportunity's arrival at this point along the western rim of Endeavour Crater coincided closely with the rover surpassing marathon-footrace distance in its total driving odometry since landing on Mars in January 2004. The team's planned investigations in the valley were nearing completion when the component images for this scene were taken. http://photojournal.jpl.nasa.gov/catalog/PIA20751
A ridge called "Rocheport" on the western rim of Mars' Endeavour Crater spans this mosaic of images from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity. The view extends from south-southeast on the left to north on the right. Rocheport is near the southern end of an Endeavour rim segment called "Cape Tribulation." The Pancam took the component images for this panorama on Feb. 25, 2017, during the 4,654th Martian day, or sol, of Opportunity's work on Mars. Opportunity began exploring the western rim of Endeavour Crater in 2011 and reached the north end of Cape Tribulation in 2014. This ridge bears some grooves on its side, such as between the two dark shoulders angling down near the left edge of the scene. For scale, those shoulders are about 10 to 16 feet (3 to 5 meters) long. The grooves might have been carved long ago by water or ice or wind. The view merges exposures taken through three of the Pancam's color filters, centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet). It is presented in approximately true color. The Rocheport name comes from a riverbank town in Missouri along the route of Lewis and Clark's "Corps of Discovery" Expedition. https://photojournal.jpl.nasa.gov/catalog/PIA21493

This artist's concept depicts NASA's Mars 2020 rover exploring Mars. The mission will not only seek out and study an area likely to have been habitable in the distant past, but it will take the next, bold step in robotic exploration of the Red Planet by seeking signs of past microbial life itself. Mars 2020 will use powerful instruments to investigate rocks on Mars down to the microscopic scale of variations in texture and composition. It will also acquire and store samples of the most promising rocks and soils that it encounters, and set them aside on the surface of Mars. A future mission could potentially return these samples to Earth. Mars 2020 is targeted for launch in July/August 2020 aboard an Atlas V-541 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. https://photojournal.jpl.nasa.gov/catalog/PIA22111

"Marathon Valley" on Mars opens northeastward to a view across the floor of Endeavour Crater in this scene from the panoramic camera (Pancam) of NASA's Mars Exploration Rover Opportunity. In this version of the scene the landscape is presented in enhanced color to make differences in surface materials more easily visible. The panorama merges multiple Pancam exposures taken during the period April 16 through May 15, 2016, corresponding to sols (Martian days) 4,347 through 4,375 of Opportunity's work on Mars. It spans from north, at the left, to west-southwest, at the right. The high point in the right half of the scene is "Knudsen Ridge," which forms part of the southern edge of Marathon Valley. Portions of the northeastern and eastern rim of Endeavour crater appear on the distant horizon. Endeavour Crater is 14 miles (22 kilometers) in diameter. The fractured texture of Marathon Valley's floor is visible in the foreground. The rover team calls this image the mission's "Sacagawea Panorama," for the Lemhi Shoshone woman, also commemorated on U.S. dollar coins, whose assistance to the Lewis and Clark expedition helped enable its successes in 1804-1806.

NASA's Opportunity Mars rover passed near this small, relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call it "Orion Crater," after the Apollo 16 lunar module. The rover's Panoramic Camera (Pancam) recorded this view. The crater's diameter is about 90 feet (27 meters). From the small amount of erosion or filling that Orion Crater has experienced, its age is estimated at no more than 10 million years. It lies on the western rim of Endeavour Crater. For comparison, Endeavor is about 14 miles (22 kilometers) in diameter and more than 3.6 billion years old. This view combines multiple images taken through three different Pancam filters. The selected filters admit light centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet). The three color bands are combined here to show approximately true color. The component images were taken on April 26, 2017, during the 4,712th Martian day, or sol, of Opportunity's work on Mars. Apollo 16 astronauts John Young and Charles Duke flew in the Orion lunar module to and from the first human landing in the lunar highlands while Ken Mattingly orbited the moon in the command module, Casper. On the moon, Young and Duke investigated Plum Crater, which is approximately the same size as Mars' Orion Crater. https://photojournal.jpl.nasa.gov/catalog/PIA21708
