sScientists 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.
