Mars Features Resemble Hydrothermal Springs

Whilst the possibily of life is being bantered about, this will also open up a new window on the internal mechanisms & evolution of The Fourth Rock from the Sun, much like the lava tubes on the volcanoes, calderae collapses, layering in the Vallis Marineris & elsewhere, volcanic rocks in Gusev Crater, examined in detail by MER A Spirit, volcanic rocks on Utopia Planitia, seen in detail by Viking 2, impact cratering density on lava flows, etc. We are definately now getting a more complete picture, of the history of the Red Planet & perhaps evidence of continuing activity??????I take there have been no updates on the supposed vent to the side of Victoria Crater? Very exciting!! Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Hi AndrewThese features on Mars are all quite old, the late Noachian/Early Hesperian, after which Mars seems to have shut down to a large extent.I think the feature you mention at Victoria is Sputnik.  It's an odd looking crater but whether it is a vent I don't know.  There is nothing else there to suggest venting, unlike at Home Plate!cheersJon  <div class="Discussion_UserSignature"> Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars Arthur Clarke </div>

It was difficult to judge on some of thos images as to how old, these features are, though my own suspicion was of the Late Noachian period.Thanks for reminding me of the name of the wierd crater next to Victoria Crater. I could not remember if it was Sputnik or Vostok (trying not to look like a right muppet, failed there), though I remember now, Vostok Crater is on the plains just to the north. MER B Opportunity drove past Sputnik TWICE, why could they have not stopped Oppy for a short period to investigate?? IIRC it was before the dust storm.Perhaps if Oppy comes out of Victoria Crater, then an investigation of Sputnik could be carried out.Yes I agree about HomePlate. The Goddard & Von Braun features are intriuging to say the least. The structure of HomePlate itself is quite interesting. Hopefully MER A Spirit can do a thorough investigation from her Wintering point. She is well placed actually to do just that. Then in the late Winter or Spring,when the sunlight is a bit stronger, hopefully drives onto Von Braun & that peculiar 'crater' Goddard.  Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

the other features near Home Plate would be even more interesting.  I hope Spirit can drag intelf there.Getting back to the original article, it was in connection with identifying promising sites for Mars sample return missions.  Spring deposits are very attractive, though high risk targets for MSR missions, IMHO.Dalhousie springs are great analogues for small Martian outflows.Jon <div class="Discussion_UserSignature"> Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars Arthur Clarke </div>

I suspect there are still some hot spring deep inside the martian crust at present days, since Mars may still has a soft core.
