A team of researchers analyzing images and data gathered by the now-defunct Phoenix spacecraft believes that the lander spotted liquid water on Mars—and that such liquid may be common on the Red Planet. But even within the Phoenix science team, not everyone is convinced.
In a study (pdf) set to be presented next week at the Lunar and Planetary Science Conference in the Woodlands, Tex., Nilton Renno, a professor of atmospheric, oceanic and space sciences at the University of Michigan at Ann Arbor, and his co-authors say that drops of saline appeared where the lander disturbed the Red Planet's surface. Renno is a co-investigator on the Phoenix mission's science team.
