Mars Odyssey Begins Overtime 122
thhamm writes "NASA's Mars Odyssey orbiter begins working overtime today after completing a prime mission that discovered vast supplies of frozen water, ran a safety check for future astronauts, and mapped surface textures and minerals all over Mars, among other feats. An extended Mission until 2006 has been approved, and I hope it will last that long, maybe doing more safety checks for astronauts :)"

So when did that happen? I remember checking in on slashdot all the time and there would always be some thing about the mars rovers almost discovering water, but always missing some piece of evicende or something. I don't remember anything about an orbiter finding huge amounts of water (well I was on vacation for a month but I figured it would be pretty big on the news or something.)
Next stop, South Polar region? (Score:5, Interesting)
Since they found indications of lots of frozen water near the surface in the south polar region, I wonder if there are any plans to send a probe/rover there?
They found "copius hydrogen" in the area, and "Researchers interpret the hydrogen as frozen water", but can we be sure without taking a look on the ground?
Seems like the next logical step...
mission performance (Score:2, Interesting)
so this is a pretty good performance, with the two rovers still working (after doubling their designed lifetime?), Mars Odyssey, MSGS and Mars Express.
and the biggest objective a huge success: yes there is/was water.
no need to argue about the use of robotic missions for me. if you asked someone 10 years ago about water on mars: "yeah. water. mars. sure
Astronauts on Mars with this evidence? (Score:4, Interesting)
But surely the fact that Mars' surface gets 2 or 3 times what Earth's surface gets would stop any missions from happening anytime soon (as in, within the next 20 years)? Or is the radiation not actually a problem?

I am in hopes that we will send a private mission to mars and not have them return. It would be far more useful to send a small mission on a one way trip, with a supply ship once a year. They could build a small base, expand our knowledge of Mars a million fold over what simple remote vehicles do today, just due to the fact that they would need all sorts of cpu power there. In addition, they would be able to control system there quickly.

He seems to see signs of water on recent Rover images, squished out by the wheels and the RAT tool.
Even if there is/ever was no life, interesting find though, that liquid water exists on such a world. I think this raises the odds of finding life somewhere else quit a bit. Maybe Europa [space.com]?

At a talk given by Chris McKay this weekend, he was asked something like "when do we give up the search for life and start terraforming?" That's kind of a sticky question because it's kind of like proving a negative. However he pointed out a region in the southern hemisphere which is older than the north, still has an earth-strength magnetosphere and is Siberian in nature. He said that once a kilometer deep core is drilled, checked for life and nothing is found that there is almost certainly no life on Mars nor was there ever.
It will take people to do that investigation. My personal hope is that nothing is found and terraforming can begin.
For a good treatment of terraforming, read Robert Zubrin's "The Case For Mars".
