4. Great Can I move there? While there is NO place left on earth not ruled by the elite!

5. I was just about to go look at porn. Now, I have to watch NASA. Oh, well. n/t

9. It doesn't get any better than NASA porn!

Well, maybe sometimes ;)

18. very cool-thanks! n/t

11. Maybe the Teanderthals

should colonize Mars and turn it into their Conservative Utopia....leave us alone.

[BadgerKid]

22. +1 for term "Teanderthals".

Will use it often.

[Ian David]

12. I think I suggested a "colloidal suspension" or a "non-Newtonian fluid" on Mars a while back.

How neat would THAT be?

[Ian David]

13. He was asked to explain what a gully is...

... and give an answer that's even MORE complex.

[Ian David]

14. Don't drink the water...

19. It will also repeat at 2pm PST on Nasa TV. nt

16. Brine shrimp From Wikipedia, the free encyclopedia

Brine shrimp
From Wikipedia, the free encyclopedia

Artemia is a genus of aquatic crustaceans known as brine shrimp. Artemia, the only genus in the family Artemiidae, have changed little externally since the Triassic period. The historical record of existence of Artemia date back to 982 from Urmia Lake, Iran, although the first unambiguous record are the report and drawings made by Schlösser in 1756 of animals from Lymington, England.<2> Artemia are found worldwide in inland saltwater lakes, but not in oceans.

Artemia is a well known genus as one member, sometimes identified as a hybrid species Artemia salina × nyos, is sold as a novelty gift, most often under the marketing name Sea-Monkeys.

Life cycle

Brine shrimp eggs are metabolically inactive and can remain in total stasis for two years while in dry oxygen-free conditions, even at temperatures below freezing. This characteristic is called cryptobiosis meaning "hidden life" (also called diapause). While in cryptobiosis, brine shrimp eggs can survive temperatures of liquid air (−190 °C or −310.0 °F) and a small percentage can survive above boiling temperature (105 °C or 221 °F) for up to two hours.<3>

Once placed in briny (salt) water, the cyst-like eggs hatch within a few hours. The nauplii, or larvae, are less than 0.5 mm in length when they first hatch. Brine shrimp have a biological life cycle of one year, during which they grow to a mature length of around one centimeter on average. This short life span, along with other characteristics such as their ability to remain dormant for long periods, has made them invaluable in scientific research, including space experiments. This ability has also enabled the use of a hybrid of brine shrimp, bred to grow larger and live longer, as Sea-Monkeys.

20. ... The images show flows lengthen and darken on rocky equator-facing slopes from late spring

to early fall. The seasonality, latitude distribution and brightness changes suggest a volatile material is involved, but there is no direct detection of one. The settings are too warm for carbon-dioxide frost and, at some sites, too cold for pure water. This suggests the action of brines, which have lower freezing points. Salt deposits over much of Mars indicate brines were abundant in Mars' past. These recent observations suggest brines still may form near the surface today in limited times and places ...

21. I made a far more interesting discovery

The diameter of the dome is 500m

23. I don't see what the discovery is...

You see a dome, whoopee, such a dome could have been formed in any number of ways, only one of which, and the least likely, artificially. Just because you see something anomalous doesn't mean you jump to fantastical conclusions. That's magical thinking and not science. Should the dome be studied further? Of course, but please don't make any claims about it(or conspiracies), when good old fashioned skepticism will suffice.

I'd actually would love to see what geologic activity created such a feature, I'm betting on an extinct magma chamber that failed to erupt. The upwelling is consistent with fluid dynamics, and since Mars doesn't have plate tectonics, there's nothing there that can prevent this feature from forming in a symmetrical way.
