A series of huge cracks etched across crater basins on Mars were caused by lakes that have since evaporated, a new study concludes.
The cracks were initially thought to have been merely a byproduct of thermal contractions in the Martian permafrost. But a closer examination revealed the cracks were too big for that explanation. Cracks caused by thermal contraction have a maximum diameter of roughly 213 feet (65 meters), according to analytical models.

Where there was liquid water, there was very likely life.

Proof positive Global warming exists. It even wiped out all life on mars.

Proof positive Global warming exists. It even wiped out all life on mars. It's Bush's fault. Bush and those damned SUVs.
Women and minorities (and Martians) hardest hit.

Were there any gaseous clouds around those cracks—like are around Uranus?

That is one of the most unscientific statements. According to what evidence do you make it? We have exactly one data point of a water and life correlation: earth. There is still no evidence one way or the other about anywhere else in the universe.

I am not talking about walking talking critters. I am speaking of microbes at best.

I know--and it's still not a valid statement to make. Maybe it's true and maybe it isn't. There is not evidence to properly say.
To: newguy357
That is why I put the qualifiers in the statement.

I see no qualifiers. You have extrapolated a line from a single data point. That is meaningless.

“very liekly” - no declaration that there was life. Just an expression of the possibility thereof.
