Researchers have found deposits of impact glass preserved in Martian craters, including Alga Crater, shown here.

This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta, the material thrown out of the crater when a meteorite hit Mars.

MRO took this image of layered, sedimentary rocks on the floor of an impact crater north of Eberswalde Crater. Billions of years ago there may have been a lake in this crater.

The South Polar residual cap (the part that lasts through the summer) is composed of carbon dioxide ice.

Although the season is late spring, carbon dioxide ice still covers much of the surface at this high latitude site.

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spacecraft orbits.

A view from NASA's Mars Reconnaissance Orbiter on April 8, 2015, catches sight of NASA's Curiosity Mars rover passing through a valley called "Artist's Drive" on the lower slope of Mount Sharp.

Streaks seen on warm Martian slopes might be caused by seeping water rich in salts that lower its freezing point far below the freezing point of pure water. These features, known as Recurring Slope Lineae, can be found on the central peaks of Hale Crater.

Recurring slope lineae (RSL) are active flows on warm Martian slopes that might be caused by seeping water.

What appear to be spiders scampering across the martian landscape are actually cracks in the surface of the southern polar region on Mars, seen by the Mars Reconnaissance Orbiter on August 23, 2009. Caused as carbon dioxide ice evaporates and escapes into the atmosphere, there is no escaping that these "araneiform" features look like our 8 legged friends!

This picture of a crater resembling a "happy face" was taken by the Mars Reconnaissance Orbiter's Context Camera. The unnamed crater is almost 2 miles (about 3 kilometers) across That's a BIG smile!

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance changed over the subsequent 30 months. The images are from HiRISE on NASA's Mars Reconnaissance Orbiter.
