Martian 'Spiders' in Sharper Look, Thanks to Volunteers
This image from NASA's Mars Reconnaissance Orbiter shows spidery channels eroded into Martian ground. This terrain type, called spiders or 'araneiform' (from the Latin word for spiders), appears in some areas of far-southern Mars.
This image from NASA's Mars Reconnaissance Orbiter shows some beautiful lava flows in Amazonis Planitia. Lava isn't moving around on Mars today, but it certainly once did, and images like this one are evidence of that.
The Tharsis region of Mars is covered in vast lava flows, many with channels, as seen by NASA's Mars Reconnaissance Orbiter. Some channels, however, resemble features that may have been formed by water.
Curiosity Destinations for Second Extended Mission
This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in September 2016 at 'Murray Buttes', and the path planned for reaching destination at lower Mount Sharp.
Curiosity's First 16 Rock or Soil Sampling Sites on Mars
This graphic maps the first 16 sites where NASA's Curiosity Mars rover collected rock or soil samples for analysis by laboratory instruments inside the vehicle. It also presents images of the drilled holes where 14 rock-powder samples were acquired.
This image from NASA's Mars Reconnaissance Orbiter shows many small craters over a larger degraded one in the northern lowlands. These small craters are smoother and shallower than their counterparts closer to the equator.
