NASA Released New Photos Of Mars (39 pics)
1A North Pole dune field nicknamed "Kolhar," after Frank Herbert's fictional world.
2Cerberus Palus crater showing off layered sediments.
3Glacial terrain looks strangely iridescent.
4A steep slope in Eastern Noctis Labyrinthus
5Dunes in a Martian crater. The red bar is an artifact of NASA's image processing.
6A possible landing site for the Mars 2020 mission NASA wants to launch in a few years.
7The Tharsis region, which is the most volcanic part of Mars.
8Terrain near the Martian equator.
9Steep-sided craters on a Martian plain.
10Ceraunius Fossae is a region dominated by volcanic flows and large cracks.
11Layers in Martian buttes found in a region called West Arabia.
12Beautiful texture in the region called North Sinus Meridiani.
13Wind-shaped features on Mars — the green bar is leftover from processing the image.
14A recent impact crater on Mars. (We're pretty sure no one put out a giant cigarette here.)
15A crater on Arcadia Planitia, a large flat region of Mars.
16The creation of "fans" around dunes may help scientists understand seasonal changes on Mars.
17A picture of Utopia Planitia, a large plain on Mars.
18Mars in all its two-toned glory.
19Seasonal dunes on Mars nicknamed "Buzzel."
20Ridges cross the Nepenthes Mensae region, which is often referred to as a river delta for the striking pattern.
21The edges of a debris apron, where cliff material eroded away.
22Alluvial fans are some of the evidence that scientists used to confirm there was once water on Mars.
23A small but recent impact crater.
24Scientists use HiRISE to monitor how gullies change over time, which could help them figure out what created them.
25Exposed bedrock on the Capri Chasma, which may once have been filled with floodwaters.
26"Spiders" are eruptions of dust caused by the way the Martian surface warms and cools.
27Eos Chasma is part of Valles Marineris, the largest canyon on Mars.
28Another gully scientists are having HiRISE monitor.
29A pedestal crater, where a crater has eroded away at different rates based on different rock types.
30Watching Mars defrost.
31Measuring changes in albedo, or how much light is reflected off the surface.
32A basin floor.
33A possible landing site for the Mars 2020 mission.
34A sinuous ridge on fretted terrain, which may be evidence of Mars' glacial past.
35Fractures in Utopia Planitia line up eerily neatly.
36Scientists think these may be pieces of rock blown away by an impact.
37Yardangs, which are sharp ridges scraped away by Mars' harsh winds.
38Near the North Pole, in an area nicknamed "Windy City."
