Life on Mars cast into doubt as Curiosity fails to find methane

[Click] Hi, is that David Bowie?

[Silence] ...

It's NASA here. We've got some news. While it's not a conclusive answer, the Curiosity Rover wasn't able to detect any traces of methane in the Gale Crater. Presence of the gas is one of the things that we were hoping would support our theories about life on Mars, so this comes as a bit of a blow. Now, there *are* terrestrial microbes that don't generate methane, so it's not as if this is a firm "no," but it's not looking anywhere near as likely as it was before. So, uh, does that help at all?

[Silence] ...

Uh, well, thanks. Bye!
