Approach to Mars
The European Space Agency's Beagle 2 is approaching Mars for a landing (bouncy, but hopefully soft) on Christmas Day (will we hear "The Beagle has landed" !). Part of its mission is to look for chemical traces of life. One of the tests will be for methane in the martian atmosphere. Methane is a byproduct of life but will not last long in the Martian atmosphere, so a positive result would be interesting. Other experiments will determine C-12/C-13 ratios since a high value is indicative of life. Two NASA craft will follow on a month later.
