Mars Volcanoes May Still Erupt

Volcanic eruptions have happened in the last 4 million years....
:)
That's only about 15 iterations "emerge kde" on my gentoo laptop
If it's as recent as 4 million years that would put to bed the dead Mars theory. The idea that Mars lacks a molten core. If there was magma that recently there would still be a molten core. It would take hundreds of millions if not billions of years to go from volcanic to a cold core. There would almost have to be liquid underground water. Good news for life and also water for explorers.
Well, we have only been closely looking at mars for (in an astronomical sense) a fraction of a second. Just because there hasn't been any evidence of eruption yet doesn't really mean anything.
Mars does have a molten core, according to JPL. Strikingly similar to both earth, and venus. Interesting stuff, none the less.
Excuse me, I don't mean to impose, but I am the ocean
1.The Great Machine has awakened and is starting the terraforming process.
2.Didn't you folks play Doom3? Hello Hellgate.
If volcanoes supposably created our atmosphere does that mean that if we leave Mars alone for a few million years it will produce it's own life? (Non-bacterial)
Have you metaroderated recently?
The major exeptions to this are Io and Europa. The major difference here is that the geological activity on these moons is thought to be the result of their proximity to Jupiter and Neptune respectively with the resulting gravitiational "squeeze" the cause.
"Regions that are smooth as a baby's bottom must have been "resurfaced" recently, in geologist's parlance."
My babies bottom is typically surfaced in an unidentifiable brown pitted substance, and is far from smooth.
Think you can program? Prove it @ the geek challenges
So where are the little green men?
Anyone have a clue?

The question is rather, is the spirit stoned?
OR
is the spirit just stuck?
OR
Has there been to much to drink?
There goes the planet...

I thought Venus was still active? http://www.nineplanets.org/venus.html " Data from Magellan's imaging radar shows that much of the surface of Venus is covered by lava flows. There are several large shield volcanoes (similar to Hawaii or Olympus Mons) such as Sif Mons (right). Recently announced findings indicate that Venus is still volcanically active, but only in a few hot spots; for the most part it has been geologically rather quiet for the past few hundred million years."
Also, geothermal energy is a great resource to have when colonizing planets. Io and Europa are not as exciting prospects for colonoization, for a number of reason, as Mars is.
stuff
(don't bother submitting it as a story, I already tried.)
If you know you are not interested, why do you desire an explanation?
For those who *are* interested, this can have any of several significance. According to an installment of NOVA on PBS called "Origions", a popular theory of planatary evolution holds that a hot molten interior in an inner planet such as Earth is responsible for creating the planetary magnetic field that shields the planet from the abrasive effects of the solar wind. Without this magnetic shield, the sun's radiation strips away the planet's atmosphere and other volatile compounds such as water. It was thought that Mars, being smaller than Earth, had a core that cooled and solidified more quickly and lost it's magnetic field early in it's life. With not magnetic field to shield it's surface, the atmosphere thinned and water became scarce.
If Mars happens to be more geologically active than we once thought, another theory will be needed to account for the signs of a wetter martian past. Quite possibly, we need to reevaulate the level of protection offered by the molten core of our own Earth against the erosive effects of the solar wind.
Stay sentient. Don't drink bad milk.
Erm weren't we supposed to stay away from Europa? All the rest of them are our's and that whole bit?
Your hair look like poop, Bob! - Wanker.
Triton, the one near Neptune, is a very strange object. One of the coldest places in the solar system yet it manages to have geological activity and even a thin atmosphere with clouds. It's also possible that the entire atmosphere collapses into a frost covering the half of the moon that's in winter at the time. Not to mention the moon orbits Neptune backwards, suggesting that it's a captured object from the Kuiper Belt. If true this means it's the largest such object, not Pluto. There are missions being planned to orbit Neptune and send landers to Triton. Should be good!

Only 20+ years to go
Mars Volcanoes May Still Erupt
so beware when u play doom3 !
fifteen jugglers, five believers
Venus isn't inactive it just has long periods of inactivity before enough pressure builds and a huge amount of its surface gets covered in molten lava. This is due to no water being on the planet thereby lacking the necessary lubrication for plate technonics and an active surface like us.

I distinctly remember reading in Dickinson, Sagan and Clarke books back in the 80s that Olympus was an active volcano. The "largest active volcano in the solar system".
