I thought it didn’t rain on Mars?

[battlecry]

I wonder why they are not thinking it could be dry ice. With so much CO2 in the atmosphere.

A Crystalized life form, that dug itself into the surface?

[Lancey Howard]

Those silicon-based life forms are pretty tricky.

[printhead]

CO2, CH4? Evaporate, sublimate? What do I know? And when did I know it?

[Kevmo]

This is big.

Of course, the next thing that will happen is the liberals will claim we introduced global warming on Mars as well.

[Man50D]

"We now understand what happened, and we can fix it with a software patch,"

Are they using Windows Vista? ;O)

[racing fan]

Global warming?

Where are the SUVs?

Just kidding.

[Incorrigible]

Water! Self sustained human colony on Mars here we come!

[spanalot]

Neat - it was protected by the layer of soil.

The original wording was Peter Smith saying “It must be ice-nine.” But then NASA edited it out for security reasons.

[popdonnelly]

I’m skeptical. It didn’t look like enough ice for one gin and tonic.

Disappearing photo-chemo-crystalization life forms.

I knew that

[InvisibleChurch]

... he said “Chunks”!

[nuf said]

yippie skippy.

Water is a necessary but Far from sufficient ingredient for life. I can save NASA money. Look east toward that big blue liquidy mass called the Atlantic Ocean. It is Full of water and life.

"that is perfect evidence that it's ice"

Why am I thinking that "White stuff that dissappears" is less than perfect evidence?

These images were acquired by NASA's Phoenix Mars Lander's Surface Stereo Imager on the 21st and 25th days of the mission, or Sols 20 and 24 (June 15 and 18, 2008). They show sublimation of ice in the trench informally called "Dodo-Goldilocks" over the course of four days. In the lower left corner, lumps disappear, similar to the process of evaporation.

Yawn. I can see seasonal polar ice on Mars using my backyard telescope. Now finding some form of life would be a big deal.

[Disambiguator]

It was probably styrofoam that blew in from Earth, and it blew away when it was uncovered. That stuff goes everywhere!

[citizencon]

Mars is the new Earth...
