Martian Surface in Perspective
16.01.2004

Spirit moved across Mars yesterday as the rover successfully maneuvered down off its lander, driving its six wheels onto the floor of Gusev crater. As planned, the robotic geologist will now begin a close-up examination of the rocks and soil around the landing site for clues to the processes that formed them.

Neutron Mars
4.09.2004

Looking for water on Mars, researchers using detectors on board the orbiting Mars Odyssey spacecraft have created this false-color global map of energetic neutrons from the otherwise Red Planet. What do neutrons have to do with water?

A Martian River Bed
5.02.1998

This canyon on the surface of Mars appears to have been carved by flowing water. Known as Nanedi Vallis, the terraces and channels visible within the canyon strongly suggest that a river of water once ran here.

A Dust Devil on Mars

Sol 5 Postcard from Mars
9.01.2004

A martian Sol - the average martian solar day - is about 39 minutes longer than Earth's familiar 24 hour day. Operating on martian time, the Spirit rover recently sent back this color postcard image, recorded on Sol 5 of its stay on the martian surface.

Spirit Pan from Bonneville Crater s Edge
18.03.2004

Scroll right and follow this breathtaking view of the martian surface from the southern edge of a small crater dubbed Bonneville. NASA's Spirit rover recorded the sharp 180-degree panorama on sols...

SEIS: Listening for Marsquakes
4.06.2019

If you put your ear to Mars, what would you hear? To find out, and to explore the unknown interior of Mars, NASA's Insight Lander deployed SEIS late last year, a sensitive seismometer that can detect marsquakes.

Spirit s 3D View Towards Sleep Hollow
6.01.2004

Working late, tired mission members nicknamed the smooth-looking depression to the left of center in this image from the martian surface, Sleepy Hollow. The picture is a portion of the 3D panorama of the Spirit rover's landing site released yesterday, constructed with data from the Mars rover's navigation cameras.

A Martian Lake Bed
11.12.1997

Look closely. In this Mars Global Surveyor image of the Martian surface just south of Schiaparelli crater, dark lines appear to criss-cross light colored depressions. One tantalizing possibility is simply that the feature near...
