When the Phoenix Mars Lander took its second scoop out of the reddish soil of Mars, it revealed whitish material beneath the surface – tantalizingly similar to the bright patch revealed by the firing of the craft’s landing thrusters. This stuff may be ice, or it may be part of a salt layer formed on top of ice.
COMMENT: Phoenix, like all good scientists, is beginning its exploration by raising new questions. THe world is tuned in for the answers.
