Mars lander is returning more detailed images from the Martian surface and is now preparing its instruments for science operations.
This panoramic view taken by NASA's Phoenix Mars Lander shows the sweeping plains of the Martian polar north.
Phoenix transmitted a 360-degree panorama of its frigid Martian world, freed its nearly 8-foot robotic arm, tested a laser instrument for studying dust and clouds, and transmitted its second weather report on Wednesday evening.
Phoenix was able to determine the size of the rocks based on three-dimensional views from stereoscopic images taken by the lander's 7-foot mast camera, called the Surface Stereo Imager. The stereo pair of images enable depth perception, much the way a pair of human eyes enable people to gauge the distance to nearby objects
