Democracy in Greece, post-crisis, pre-Syriza:


The one MP in opposition during this clip is now President of the Greek Parliament. She's also on record about the Lagarde list of 2062 Greek tax dodgers, 6(!) of whom were checked up on. The list was handed over in 2010, and it has been held under wraps at the bidding of the IMF.

That makes sense since space is a vacuum that they would test it in a vacuum. For some reason, I was thinking it was a land based telescope. I guess those are pretty much obsolete at this point.

It might help to start with what the Backplane Pathfinder actually is - it's a non-flight replica of the Webb telescope’s center backplane (that link has more info and pictures).

Chamber A allows simulating the cold environment the real telescope will face in space, and is the same vacuum chamber where Apollo spacecraft were tested.

Now, to answer your question: They are testing the test procedures for the real telescope! (source: NASA). I realise that doesn't exactly answer your question, but I haven't found details of the actual tests they plan to run... so as a distraction, here are some more images - http://jwst.nasa.gov/images_backplane.html
