A new paper argues that HiRISE photos show evidence for recent short-lived surface water flows. Neat pictures on Phil Plait's site (my source for the news).
It would be interesting to learn if there was any MGS coverage of the same area. TTT |

These gully-like features in Russell crater were described by Nicholas Mangold and others in 2003 using MGS MOC and MOLA images:
Mangold, N.; Costard, F.; Forget, F. (2003). Debris Flows over Sand Dunes on Mars: Evidence for Liquid Water. J. Geophys. Res., 108(E4), 5027, doi:10.1029/2002JE001958. Michael Carr also discusses them briefly in his book The Surface of Mars, 2006. Tom FULL INLINE QUOTE REMOVED - Admin |

QUOTE (Tom Tamlyn @ Apr 12 2010, 01:12 PM)  It would be interesting to learn if there was any MGS coverage of the same area. There are a number of MOC narrow-angle images of the Russel dune gullies as the area was monitored for change. MSSS put out a few captioned image releases of them: http://www.msss.com/mars_images/moc/2003/04/27/index.html http://www.msss.com/mars_images/moc/2005/05/08/index.html http://www.msss.com/mars_images/moc/2005/11/05/ -------------------- About Me: http://www.msss.com/about-us/tanya-harrison.php

Say, were you guys the victims of those pranks in high school, too?

on arXiv today: Martian gullies: Produced by fluidization of dry material
-------------------- I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.
