Thursday, November 13, 2003 New Evidence For Long-Term Liquid Water Niger River Delta. Credit: BBC New evidence released by NASA researchers today builds part of a powerful case for a long-term liquid water presence on Mars. Detailed images taken by orbiting spacecraft show clear signs of "meandering" water in what appears to be a river delta in an unnamed crater in the southern hemisphere. In hydrology, meandering is considered evidence for a long-term flow of water. "This latest discovery by the intrepid Mars Global Surveyor is our first definitive evidence of persistent surface water," said Dr. Jim Garvin, NASA's Lead Scientist for Mars Exploration. The region has been suggested as a possible landing site for the 2009 Mars Science Laboratory. (More info: NASA Planetary Photojournal) @ 17:33 EST
