Crater supports evidence for life on Mars

Scientists believe that the components for life have been present on Mars for millions of years.

The revelation has come from new data from the Mars Reconnaissance Orbiter and Mars Express spacecrafts pertaining to materials present within a large crater on the planet's surface. Rocks and materials thrown up by the impact appear to contain minerals that are believed to have been affected by water, a discovery that suggests life could have existed below the Martian surface.

"'All the ingredients were there for life, but only small single-cell organisms could have survived in those conditions," said study lead author Dr Joseph Michalski. "But I would now be more surprised if there was never any life on Mars, than I would be if we did one day discover that simple life lived in that environment."

"Research published in the journal 'Nature Geoscience' suggests that the components required to sustain simple microorganisms could have been present on Mars for much of its history."

Even if there isn't life there now, this is certainly an exciting time to be alive. Who knows what we'll know about Mars 50 years from now?

I'd like to know how they can be so sure there wasn't any lake for millions of years. Would they know if it was 'only' 100,000 years ago?

Yes thats right..... we would all go absolutely mad, a presidential address, religious leaders esposing many ideas and mantras, debunkers, the world would go nuts. Thats why we will never be told.

I think that's ridiculous. After a while emotions will settle down, and it will become a simple accepted fact.

Does the revelation that mars currently or in the past supports life really surprise anyone? Not me.

Who knows what they really know now?

We have had the technology to determine whether or not there is now, or has been in the past, life on Mars....for the past 50 years. It's laughable when scientists say that with the new space-based telescopes...that they will be able to say for certain that there is life on a planet light years away....but they can't say for certain regarding a planet they've landed on several times? Regardless of what you believe, NASA knows the answer already. It's their funding that fuels the entire thing. If I owned a private space-faring company, I'd milk it for all it was worth t... [More]

I don;t know where you got the idea from that they can determine whether life exists on planets 15 light years away. What they CAN determine is whether the conditions on that far away planet could make the existence of life 'as we know it' possible.
