In the article, Alicia Chang from AP writes:
But if there were past or present life on the red planet -- a big if -- scientists speculate it would likely be similar to some extreme life on Earth -- microscopic and hardy, capable of withstanding colder-than-Antarctica temperatures and low pressures.AND
Most living things on Earth thrive not only in the presence of water, but also need sunlight, oxygen and organic carbon. But the range of conditions in which life can survive has been expanded with recent discoveries of micro-organisms trapped in glaciers and rocks or living in volcanic vents and battery acid-like lakes.The AP article is quite reasonable, as far as science reporting goes. However, there is some stink going on in the bloggosphere about AP bullying bloggers regarding fair use so you might want to check out AP: Stupid, it hurts! and AP Files 7 DMCA Takedowns Against Drudge Retort and AP/Drudge Retort “Resolution” Leaves Fair Use Questions Unanswered.
