Looking for Life Again

This article is a brief look at what the pursuit of life on Mars is going to be like. First the author explains why looking for current life is unfeasible at the moment, because any life is miles below the surface - miles that no rover will be able to dig through. The article then outlines what we will be able to do on Mars, which is to look for evidence of past life. A new rover scheduled for launch in 2009 will be able to perform this task of looking for fossils. Such a rover will hopefully be looking at old sedimentary deposits on Mars using organic chemistry and some type of mass spectroscopy. What the article claims we may find are something like stromatolites, colonies of microbes. These colonies will be very hard to find, but locations where water once flowed are, as always, the best bet.
