[quote]NASA's Curiosity rover has answered a key question about Mars: the red planet previously had some of the right ingredients needed to support primitive life. The evidence comes from a chemical analysis by Curiosity, which last month flexed its robotic arm to drill into a fine-grained rock and then test the powder.[/quote] [url]http://www.brisbanetimes.com.au/technology/sci-tech/rover-shows-mars-could-have-supported-life-20130313-2fzg4.html#ixzz2NNwc1XYv[/url] Video by Scishow: [url]http://www.youtube.com/watch?v=Q3QNvHbXtlE[/url]
i'm quite interested in why it doesn't have life anymore
[QUOTE=_Maverick_;39896310]i'm quite interested in why it doesn't have life anymore[/QUOTE] I think the wiki page explains it. Something to do with the magnetosphere dying away a bit and solar winds blasting it, temperatures rising, water boiling away, extreme aridity and general creation of an environment unable to sustain any life that we know about
[QUOTE=_Maverick_;39896310]i'm quite interested in why it doesn't have life anymore[/QUOTE] That's to imply it did. For all we know, the conditions couldn't have lasted long enough for life to spawn.
Science! :eng101:
hah, primitives

As the atmosphere was stripped away the greenhouse effect keeping Mars at habitable temperatures would have dwindled away making it a colder place.
