Ice on Mars!

And not just tiny bits, but LARGE amounts of it!



<< Observation of large amounts of ice on Mars

Basis of observation:

The evidence for large amounts of ice in the southern hemisphere of Mars comes from three different instruments in the Gamma-Ray Spectrometer (GRS) instrument suite on board the 2001 Mars Odyssey spacecraft: the Gamma Ray Sensor, the Neutron Spectrometer (NS), and the High-Energy Neutron Detector (HEND). Each of these instruments has detected the signal expected from a large amount of ice in the surface, or regolith, of Mars. The presence of ice is indicated by signals due to hydrogen, one of the major constituents of water, which has the chemical formula H2O. This formula signifies that water is made up of two atoms of hydrogen combined with one atom of oxygen. We determine the amount of hydrogen in the soil by two different techniques. One relies on the ability of hydrogen to slow down, or moderate, neutrons and the other relies on the fact that hydrogen can absorb a neutron and then emit a gamma ray of a specific and characteristic energy. We have seen both of these effects in the initial data from the Mars Odyssey GRS. >>

<< Not sure if this is cool or scary. >>




its very cool.


if everything goes as expected, mars might be inhabitable in several hundred years. 🙂

You should mean when is the next probe due to crash there? 😉
 
Maybe terraforming, ala the movie Mission to Mars, should be attempted.

Or maybe all that Hydrogen is just the fuel for a huge Hydrogen bomb that some alien species has made into a Doomsday device! 😱 They came to Earth, they probed some trailer trash, they freaked, and then decided that they didn't want humans to reach their planet. Solution: Use Mars as a giant space mine that'd take Earth out if necessary.
 
All a theory designed to garner tax money for another probe...and I don't care if Mars is 3/5 water! We ain't got the technology to go there and back and live.....
 
Alright, time to start adding CO2 to it's atmosphere to warm the planet up and give it an atmosphere.
 
What would be scary to me is if we send a probe and it comes back with some ice samples. But as it is thawed and examined we noticed little microbes swimming in it. Then since we don't have any immunity to these Martian bacteria, the entire population of Earth dies.

*snigger*

Hopefully NASA-engineers will have decided to solely use the Metric system by then 😀

We have the technology and going there and back again is quite feasable. The only thing that's lacking is money and the desire.


After all, if robots can do the same work as humans, but much more cheaply, then why bother with humans?

instead of 1 space crew you can probably send 50 probes there.

Hey, those unit conversion problems are REALLY HARD. They aren't easy like the high order ODEs that govern planetary motion.

Yeah, just imagine converting inch to millimeter. I'll take calculating the orbit of, for example, Mars over that any day 😛

Not even close unless to would have an unlimited budget and even then the chances of survival for the trip would be less than any endeavor in man's existence.
We have yet to even get close to meeting the requirements of the human body for that long in space let alone the mechanical/scientific challenges.
