Your support makes all the difference.Scientists have discovered a giant chasm (left) on Mars nearly three times deeper than the Grand Canyon in Arizona, as well as evidence that an ocean bigger than the Pacific may once have existed on the planet, it was revealed yesterday.
The latest Martian findings came from the Mars Global Surveyor spacecraft, which began orbiting the planet last month in preparation for a 30-month mapping operation. Scientists told reporters at a news conference at Nasa's Jet Propulsion Laboratory in Pasadena, California, that the early results from the orbiting spacecraft were "remarkable".
The mapping project proper is not due to start for another six months. Yesterday's results came from initial probes of the surface as the spacecraft was establishing a circular orbit. - Reuters
