The American space agency, NASA, has said it has found evidence of water on Mars. Photographs from the Mars Global Surveyor, which is mapping the planet, show gullies, channels and deltas, which indicate the presence of water near the Martian surface. At a news conference in Washington, a NASA scientist said that had these features been found on earth, there would have been no question that water was responsible. NASA says the findings have "profound implications for the prospect of life".
The new conclusions are a huge boost to NASA, which lost two Mars missions in a row late last year. The space agency is planning missions to Mars in 2003 and 2005 which will include the use of a robot to sample the planet's surface.
