NASA's Phoenix Lander Robotic Arm Camera Sees Possible Ice: "Scientists have discovered what may be ice that was exposed when soil was blown away as NASA's Phoenix spacecraft landed on Mars last Sunday, May 25. The possible ice appears in an image the robotic arm camera took underneath the lander, near a footpad.
'We could very well be seeing rock, or we could be seeing exposed ice in the retrorocket blast zone,' said Ray Arvidson of Washington University, St. Louis, Mo., co-investigator for the robotic arm. 'We'll test the two ideas by getting more data, including color data, from the robotic arm camera. We think that if the hard features are ice, they will become brighter because atmospheric water vapor will collect as new frost on the ice.
