    "A fundamental question for this mission is whether Mars could have supported a habitable environment," said Michael Meyer, lead scientist for NASA's Mars Exploration Program at the agency's headquarters in Washington. "From what we know now, the answer is yes."
    An additional drilled sample will be used to help confirm these results for several of the trace gases analyzed by the SAM instrument.
    Pretty cool news, don't you think?

    There is also the possibility that it is going to sustain life in the future, as all the planets are gradually getting closer to the Sun. by the time it gets too hot on Earth, it may be comfy there.

    I love the idea of humans eventually colonising Mars, although i suspect we'll have destroyed ourselves before that happens.

    It's not really news though. It's been known that Mars was capable of harbouring life once in it's past for a long time now (the water-weathered features, for a start amongst other things).

    Watch this:

    The 'inevitable' end of the human race via apocalypse is like a heavily ingrained urban myth (in fact it IS a heavily ingrained urban myth).

    I know doomsday is a popular set of memes within human culture but I think people need to face the reality.

    In all likelihood our species is going to endure eons of existence. It'll probably not be as exciting as The Walking Dead or Mad Max or any other shock & awe End of Time scenario but hey, colonising Mars isn't that much of a poor second.

    Mars can't sustain a thick atmosphere, technically Mars could sustain life now had it a thicker one.

    Mars will never be habitable without substantial outside interference.

    But also a reminder that a planet that was once hospitable has become impossible, as will Earth.

    Given the average longevity of a species on earth is only a couple of million years or so, this is unlikely to be relevant for humans.

    Earth will go the way of Venus, not Mars, and that will take another billion years.

    Humans aren't exactly "average"; we've put a man on the Moon and we certainly have the technology to start terraforming Mars, although at great expense.

    You think that, unlike other animals, humans will not be vulnerable to diseases, can never run out of food, can't reproduce beyond the capability of their environment to support them, will never destroy themselves in warfare, and aren't susceptible to catastrophic natural events like meteorite strikes, eh?

    While all those things might happen. Comparing humans to other animals in terms of survival is quite silly. The chances of all those problems being overcome is also very high. Humans are the first species (that we know about) to successfully adapt to environmental chances faster than evolutionary change normally allows.

    It's objectively true that we are better with coping with diseases, better at expanding our food supply, better at increasing the environment's ability to support us, have seen a long term decrease in violence between humans, and are better at avoiding catastrophes, than any other animal. If an asteroid was headed for Earth the only species which could even notice it before it hit, and the only species with a chance to stop it, would be humanity.
