Odyssey is orbit around Mars so none of the samples could come from direct sampling. The 3 instruments are:

THEMIS: The Thermal Emission Imaging System is a camera that images Mars in the visible and infrared parts of the spectrum in order to determine the distribution of minerals on the surface of Mars.

GRS: The Gamma Ray Spectrometer uses the gamma-ray part of the spectrum to look for the presence of 20 elements from the periodic table (e.g., carbon, silicon, iron, magnesium, etc.). Its neutron detectors look for water and ice in the soil by measuring neutrons.

MARIE: The Martian Radiation Experiment is designed to measure the radiation environment of Mars using an energetic particle spectrometer.

Are they saying their instruments detect water or do they detect hydrogen which is a component of water? Hydrogen could be bound to any number of elements besides oxygen. Let's make them be honest.

"Do these instruments use different methods or the same, and do any of them test actual samples?"

Remote spectroscopy is just as valid as taking samples.

"I would agree, except the findings are being reported along side a call to go to Mars. Not that I'm opposed to exploration, but let's do it for the right reasons, IE. to see what's there, not to pour money into trying to prove the theory of life on Mars."

The major SHORT-TERM importance of the findings means that any exploration can be done far less expensively (fuel for the return trip can be generated on-site instead of having to be carried along, as well as the oxygen needed for the stay). Longer-term, the presence of water means that colonization is possible.

Balto_Boy: The Planetary Society conducted a survey for NASA concerning the public's priorities in space. Excerpt below:
In the two weeks that the questionnaire was posted on the Society's website, over 50,000 people weighed in with their opinions. For many of the questions, those opinions vary widely, but a few definite favorites did emerge.

"More than 90% of survey respondents ranked exploration of Mars among the top five mission priorities for NASA, thus outpacing all other Solar System mission categories" said Bruce Betts, Director of Projects at The Planetary Society

nightdriver: I believe the initial results reported from Odyssey in February cited the abundance of Hydrogen. This week should report "water ice" which implies that Oxygen should be there also underground.

Re: Maybe we should land an SUV there and just let it idle. :)

Mars NEEDS our industrial by products... a massive atmosphere of "greenhouse" gasses to moderate and warm the planets surface to the melting point of ice.

a few bunker busters could speed things up by opening up the planets crust, perhaps triggering volcanic eruptions of ash and magma that would raise the temperature a degree or two a year... acts of "terraforming" so to speak.

Bubble colonies could be set up there to smelt Iron, and exotic metals, using the ice as a coolant, and the gaseous byproducts could be dumped first of all, into the bubbles, so they would support plant growth and oxygen generation... and then as things get "balanced" in the bubble, or bubbles, the area outside the bubbles could be flooded with massive emisisons of carbon dioxide as well.

It could become a manufacturing planet, with a penal colony there for environmentalists, who want ot keep their NEW HOME pristine and unspoilt by mankind. They could protect the environment there, by moving OUTSIDE THE BUBBLES...

just speculating of course.

An interesting note of difference between Malin Space Science Systems and the Mars Odyssey team.

On MGS's Weekly Weather report for May 7, 2002.

Malin shows the "Erosion of North Polar Layers and Genesis of nearby Sand Dunes" and summarizes with The new views of the martian north polar cap obtained in 1999 and 2001 suggest that it may not contain as much water ice as previously believed. Indeed, the amount of ice may be as little as half of what was once thought.

Quite different from the latest revelations.

I saw that. If true, why doesn't it anyway? What conditions need to be met to create a state of earth-like oceans on Mars?

How about temperatures warmer than the freezing point of water?

Not that I'm opposed to eating, but let's do it for the right reasons, IE. to keep our bodies alive, not to waste money trying to enjoy the taste of the food.

I posted my reply to 1/2 of what you commented on and hit the "post" button too soon. My next reply to you was in repsonse to your comment on missions to Mars. What I was showing you is that manned missions to Mars aren't just thrown into the mix by only NASA everytime. Before reviewing and redesigning NASA's priorities earlier this year they asked the American public. The public that responded wants man to go to Mars.

An asteriod hit could have thrown up sufficient material to cool Mars. This is the hypothesis for the dinosaur extinction 65 Million Years ago.

Arnold found the Martian machine to terraform the planet and those gigantic, molten, metal rods released the O2 into the atmosphere. Arnolds eyes did not pop!

So we terrraform and build an outlet valve for our planet. Notwothsatnding the previous post about the Prof Steiner who was submitting a proposal to the National Space Society this past weekend for designating the moon, mars, actually the entire heaven as a "World Heritage site"!

HACCCH PATOOEY!

What's so exciting, exactly? Oooh! Water on mars! Big deal. Book-mark this link. Return to it after the probe takes ice samples. Quote me: They will not find any traces of life. Watch.

Why are you so certain they will find no sign of life? Where in the bible did it state we were the only place life exists? They have found life in the depths of ocean vents and in deep core samples from oil wells all over the world. Why not on planets too? Maybe God put them there for us to have dominion over them too, as soon as we figure out how to get there.

I'm mildly curious myself.

(but only mildly, since I doubt that there was a point)

Since I have stated my support for exploration, you don't need to sell me on that. I just find that calling for a manned mission to Mars on the heals of this discovery to be a little suspect. IMHO, unmanned craft exploring the region would probably be a more workable solution in the near future anyway.

No need to worry. "HACCCH PATOOEY" is what’s going to happen to people in the end with their silly leftist ideas. Off-world economic expansion is an eventuality.
