Ice ice baby
the us Mars Odyssey spacecraft has discovered massive ice fields on the planet. Scientists already know that water exists on Mars, but these latest images showing that ice may be abundant on the planet bolster theories that life exists or once existed on Mars. "The signal we have been getting are loud and clear,' said William Boynton, principal investigator for the gamma ray spectrometre instruments on the craft. "The results are exceeding our expectations,' said Roger Gibbs, the Odyssey deputy project manager for nasa 's Jet Propulsion Laboratory.
The ice was tracked by detecting hydrogen, which is the main element in water. Large amounts of hydrogen were detected within the top 0.9 metre surface of the planet ( www.nandotimes. com , March 1, 2002). The images also indicate that water ice is mixed with dust and rocks under the surface for a broad region of the planet
