Findings collected by the Mars rover Spirit gets scientists excited for what other secrets the Red Planet may hide

Scientists have conducted a lot of research to discover signs of water and possible life on Mars.  A recent discovery by a NASA rover has created excitement in the scientific community: the Mars rover Spirit collected soil samples that makes scientists strongly believe Mars was once wet. 

The rover found some Martian soil with high levels of silica, which needs water to crystalize.  Basic chemical analysis on the soil revealed the soil composition contained up to 90 percent silica.  This soil, located in Gusev Crater, is the strongest evidence that water, at some point in the planet's history, existed.

Scientists are unsure how the silica deposit in the crater originally formed.  The most likely theory is that soil mixed with acid vapors, created by volcanic activity, along with a strong presence of water.  Another popular idea is that the silica was created from water from a hot spring.

Spirit's discovery "reinforces the fact that significant amounts of water were present in Mars' past, which continues to spur the hope that we can show that Mars was once habitable and possibly supported life," said Doug McCuistion, NASA Mars exploration program director.

Oddly enough, the silica discovery happened due to a Spirit mechanical problem.  The bright patches of silica-rich soil were discovered when one of the rover's wheels dragged through the topsoil, revealing the bright colored silica-soil underneath.

Scientists are anxious to continue their research to discover what else is on the Red Planet.  Research indicates ice under the Martian surface varies in depth from location to location.
Late last year, NASA researchers used the Mars Global Surveyor to discover water flowed recently on the Red Planet.

This is a joke

Yes, ok, it once probably had water on it. Comets have water, lots of shit has water. Water doesnt = life. suX0rz.

Yet, a half year ago I made a comment about the new "discovered" water on mars possibility on here. I said it doesnt have it. Everyone said that saying that is stupid and im not an "expert". I said it on another billboard place and they said I was ignorant.

well now, fuckers, yes, it doesnt have it, didnt have it when I said it didnt either. And wont until I take a piss on the surface. Shows how unread/unknoweldgable people can be on here. geeks just love to believe life is everwhere even if they dont have a life themselves. paradox.

moan. lets see how long it takes to get to -1.

yeah baby.

One of many comments that makes one lament the fact that the lowest rating a post can attain is -1.

I'm certain I'm not alone in agreement with 'Everyone' and 'they': You're stupid AND ignorant.
