This is a joke, right? Pluto is about 20 degrees above absolute zero. EVERYTHING on Pluto is frozen solid, including all gases.
Not *quite* correct -- one of the reasons for the immediacy of the launch is to arrive at Pluto before its tenuous atmosphere freezes. We know there is an atmosphere, and we *think* it will still be there until 2020, but the sooner we arrive the better.
Otherwise, yeah, the article is a joke. There is no life on Pluto...
