    Peeling Back Layers of a Martian Polar Ice Cap

    This artist's animation illustrates how NASA's Mars Reconnaissance Orbiter used radar to map the insides of the north polar ice cap on Mars.

  • area where dust devils detected

    Phoenix Landing Area Viewed by Mars Color Imager

    NASA's Mars Reconnaissance Orbiter captured this view of a large region of northern Mars that includes the Phoenix mission landing target area in the lower right quadrant.

  • area where dust devils detected

    Context Camera Spots Dust Devils at Phoenix Landing Site

    In preparation for the landing of the Mars Phoenix Lander, NASA's Mars Reconnaissance Orbiter has been monitoring weather in the region around the landing site.

  • wide view of area showing where Phoenix will land and dust devils

    Context Camera View in Phoenix Landing Region in Martian Arctic

    NASA's Mars Reconnaissance Orbiter took this image of Martian northern plains, including ground within the targeted landing area for NASA's Phoenix Mars Lander.

  • Mar's moon, Phobos

    Phobos in Stereo

    Two views of the small Martian moon Phobos, taken 10 minutes apart by NASA's Mars Reconnaissance Orbiter, are combined to produce this stereo view of Phobos.

  • Mars' moon Phobos

    Phobos from 6,800 Kilometers

    NASA's Mars Reconnaissance Orbiter was about 4,200 miles from Phobos, the smaller of the two moons of Mars, when the orbiter's high-resolution camera took this image of the moon.

  • Mars' moon Phobos

    Phobos from 5,800 Kilometers

    One of two images that NASA's Mars Reconnaissance Orbiter took of the Martian moon Phobos on March 23, 2008, this view was captured from about 3,600 miles away from the moon.

  • Mars' moon Phobos in color

    Phobos from 6,800 Kilometers (Color)

    The largest feature on the Martian moon Phobos is the crater named Stickney, with is about 9 kilometers (5.6 miles) in diameter, in the lower right of this image taken by NASA's Mars Reconnaissance Orbiter.

  • Phobos from 5,800 Kilometers (Color)

    Phobos from 5,800 Kilometers (Color)

    Combining exposures taken in blue-green, red and near-infrared light yields this color image of the Martian moon Phobos, in which the bluer material around the edge of the largest crater may be some of the most freshly exposed surface of the small moon.

  • Mars' moon Phobos

    'Marsshine' on Shadowed Part of Phobos

    In this image from NASA's Mars Reconnaissance Orbiter, craters on part of the surface of the Martian moon Phobos that is shaded from direct sunlight are visible because the moon also is illuminated by sunlight reflected off Mars, or "Marsshine."
