Water on Mars ?

By sm | December 7, 2006

Nasa says it has found “compelling” evidence that liquid water flowed recently on the surface of Mars. “We’re now realising Mars is more active than we previously thought, and that the mid-latitude section seems to be where all the action is” said Phil Christensen, Arizona State University.On BBC “Oded Aharonson, an assistant professor of planetary science at the California Institute of Technology (Caltech) said that while the interpretation of recent water activity on Mars was “compelling,” it was just one possible explanation.Aharonson said further study was needed to determine whether the deposits could have been left there by the flow of dust rather than water.”Details of the work appear in the journal Science.
