It's typically more efficient for me to wait until you post a link here, Alex Your wish is my command. MSSS link. EDIT: And I believe the paper will be published in the December 8, 2006, issue of Science. This post has been edited by AlexBlackwell: Dec 6 2006, 06:00 PM |

We now have a new unit of measure; Swimming Pools.

very nice summaries on the msss page. Something else to look at with more detail with HiRISE perhaps?

A very good press confernce, good questions.
I have been a child during the Voyager encounters, but the discovery of frequent liquid water on mars is something I compare to volcanism on Io or gryovulcanism on Triton. Just great. The legacy of MGS continues. May she rest (or circle) in peace. Analyst |

It is interesting, but the news that Mars gets hit by impact craters, and that gullies are present-day phenomena (given the crater counts on previously observed gullies) isn't that shocking. Interesting, but not shocking. I would put it on the level of the discovery of lakes on Titan, a discovery which just confirmed that we were at least on the right track with Titan. -------------------- &@^^!% Jim!

I recorded the NASA TV internet stream of the entire conference. I'll upload it somewhere once I convert it to an appropriate format.

I'd be willing to bet that when CRISM focuses on these gullies they'll find salts of some kind. I'd even put a smaller wager on sulphate salts. As Steve Squyres mentioned in response to a question at Open University, the "water" on mars is acidic and inhospitable to life. That suggests that this AP article may be premature.Martian find raises chances of life ALICIA CHANG ASSOCIATED PRESS December 6, 2006 ... "This underscores the importance of searching for life on Mars, either present or past," said Bruce Jakosky, an astrobiologist at the University of Colorado at Boulder, who had no role in the study. "It's one more reason to think that life could be there.'' ... Steve |

I would not be surprised if the bright deposits are some kind of sulphate salt. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

NASA Images Suggest Water Still Flows in Brief Spurts on Mars

As Steve Squyres mentioned in response to a question at Open University, the "water" on mars is acidic and inhospitable to life. That suggests that this AP article may be premature. Steve Well, we have evidence from two landing sites for acidic water in the form of sulfates. But don't forget that OMEGA has found plenty of evidence for gypsum and kieserite all over Mars, which are neutral salts and don't necessarily imply an acidic envrionment. |
