NASA's Open Source Cloud

How is this related to the OpenStack project? I know NASA was an original partner in that

I was unable to find a public link somewhere. Is it actually open source and available for download?

Looks cool. Is the advantage to this that its close to Nasa datasets?

I'm surprised no one has commented yet. This is pretty freaking awesome.

from their FAQ<p>Q Who can use Nebula? A Nebula is available to NASA’s internal project groups. Nebula is not available for use by private industry or by the public. Nebula is also currently acting as a test-bed for Federal Cloud Computing technology for The Office of Management

Gotta love the Digg and Delicious icons in the footer.
