I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

Huh. I'd always thought that hydrogen needed to be highly pressurized to freeze; guess I was confusing that with what's needed to achieve its 'metallic' phase. Pretty ingenious, and as you said in your blog, Emily, this looks to be an exciting mission!

I know it's really premature to begin talking about what to do after WISE sublimates all it's solid hydrogen before it's even launched. Nonetheless, I imagine there must be some contingency planning for a WISE warm mission analogous to that of Spitzer. See the discussion of Spitzer beginning at this link.
Among the things NASA mentions is the detection of asteroids during the Spitzer warm mission. WISE warm might be able to continue its asteroid survey. Steve M |
