NASA's Opportunity rover appears as a blip in the center of this square. This image taken by HiRISE, a high-resolution camera onboard NASA's Mars Reconnaissance Orbiter, shows the dust storm over Perseverance Valley has substantially cleared.
This image, acquired on May 13, 2018 by NASA's Mars Reconnaissance Orbiter, shows sand dunes scouring what appears to be a highly-cratered, old lava flow in the Tempe Terra region, located in the Northern Hemisphere.
This image from NASA's Mars Reconnaissance Orbiter shows Ganges Chasma in the northeast portion of Valles Marineris. Scattered hills on the canyon floor may be remnants of chaos terrain that formed from collapse of the canyon.
This image from NASA's Mars Reconnaissance Orbiter shows Roddy Crater on Mars, home to several large alluvial fans, which formed as water moved sediment from the mountainous crater rim and deposited it onto the flatter crater floor.
