These streaks on Mars are really exciting! If you haven't heard, there are dark, water-like streaks appearing on Mars in intervals of months. And, yes, this is REAL SCIENCE! IF you go to http://www.angelfire.com/on2/daviddarling/ you can see some pictures of them. They look as if they are either bursts of groundwater or maybe even some biological phenomenon. It seems that it is probably salty water running downhill. WOW! This really increases the chances for life on Mars. A few weeks ago I would have said the probablity of current life on Mars was about 10%, but now I would give it about a 50/50 shot.

On a similar note, Mars Odyssey, which I think is the probe that took the images, is really doing a fantastic job. After finding ice buried under almost half of the Martian surface and measuring the radiation levels in Martian orbit, it now shows us what is probably water flowing right now on Mars.

I can't wait for the Mars Rovers to launch!

I think it will be exiting when we can get a closer look at what this is. Haven't pictures before shown a thin atmosphere? This new stuff is all the more reason why we should get a Mars manned mission going soon. If it is water, it's an incredible discovery. I saw on that site that there might be microbes in the Venusian atmosphere as well. Learn something new everyday!

Space.com (http://www.space.com/scienceastronomy/streaks_mars_021211.html) had these article a few months ago. There are many other (http://www.space.com/scienceastronomy/headlines-9.html) which seemed to come within a short space of time as Mars Odyssey did its thang. It was great to hear more discoveries leading to the improved prospects of life of some kind.

Tonight at 0100 BST, The Sky at Night will be airing on BBCONE. This month's episode is about Beagle 2, a British Martian Lander that will be carried on ESA's Mars Express. They might mention all the stuff that's going on with Mars Odyssey.

Beagle 2 has some very exciting and ingenious instruments. Check out www.beagle2.com

The most interesting one is called the "mole", which is like a motorized soil analysis instrument that can actually burrow through the soil. Look at the site.

Found this topic.. Don't ask how. :P

The Beagle looks interesting. I'd be intereseted to know more about how the Mole works, internal schematics and things like that. :) -Colt

Excellent post BigJim, I agree this could be very significant ..and this ain't Hoagland! .. I like the site you posted, I surf alot and never knew it existed, it's very interesting and bookmarked .. thanks

The thing that upsets me though is that Hoagland actually made these claims some time ago - and for once he is being vindicated... :o Go figure.

This kind of news totally rules though - the biggest question I have though, is exactly how long does one of these 'water-flows' last before it evaporates in such an extremely arid environment? That would go a long way towards establishing the possibility of life anywhere beyond small microclimates under the Martian surface...

With the Mars stuff on that site it looks legit, but the SARS from the Stars is a baseless theory. I went to the link. It looks like it's legit. The scientist involved has been trying to make a case 'for 30 years' that organisms are arriving from space to this day. Genetic mapping of epidemics provides evidence his theories are wrong. But it sounds like they were plausible until we learned more. But it is a shame he's teaching in an astrobiology program because his main ideas are no longer valid.

I love the latest and greatest they are discovering about Mars. I've heard some of the water evidence from a NASA panel on the NASA channel a year or two ago. Or else I heard it in a planetary science lecture and I'm having false memories as to who said what when. But I did see the pictures before showing the water drainage patterns and the discussion that the features were superimposed on recent dust storm deposits.

Hoagland is a mixed bag. He's come up with some prescient ideas, like the possibility of life on Europa, and has some solid stuff on his site, like the disproof of the Apollo hoaxers. But then he goes off about crystal shards on the Moon, arcologies on Mars, or a Masonic conspiracy at NASA.

... And hyperdimensional physics, an ancient spacefaring human culture... etc.

You're right though ToSeek - he's obivously got a clue - but it seems that anytime he does something beneficial to his credibility, he seems to go and find a conspiracy in an episode of the West Wing.

One needs to go no further than here (http://www.enterprisemission.com/iraqmars.html) to realise that he is also money driven in his outspokenness.

Yes he has said pertinent things - but I always, always have the salt shaker around when something new pops up on his site.

But what about the giant Sandworms on Mars (http://www.badastronomy.com/phpBB/viewtopic.php?t=7012)? :o

:lol:

Only his take is that it's the remnants of the ultimate Martian mass-transit system! Glass Tubes.

Looks great BigJim. Could be shifting sand dunes. Could be avalanches that do not look like what we have on Earth because of gravitational differences. Evidence of water on Mars would be incredible. I hope that the next couple of probes find this evidence!

Sure is fascinating...

MSSS take on it back in 2000.. (http://barsoom.msss.com/mars_images/moc/1_31_00_dunes/slopestreak_dunes/)

And now this year.. (http://barsoom.msss.com/mars_images/moc/2003/05/07/index.html)

If only this were not b&w - people wouldn't claim this is a river (http://barsoom.msss.com/mars_images/moc/2003/07/11/index.html)

More streaks. (http://barsoom.msss.com/mars_images/moc/2003/07/05/index.html)

It's fascinating, but the official tilt on the subject is mass movement. And I consider it suspicious that such phenomena is only occuring on quite highly graded slopes.
