Space Shuttle Discovery, which I saw on Pad 39A from about a mile away 2 weeks ago today, was rolled back into the Vehicle Assembly Building (VAB) on Dec. 22 for further tests.
The tests consist of x-rays of all 108 aluminum stringers in the External Tank (ET) and will hopefully shed some light on why cracks were discovered in several of the stringers which are located in the ET intertank.
The work is supposed to commence today and continue for the next week. Dec. 30th is currently scheduled as being the decision point on whether modifications will be needed on the ET.

I'll update you as facts become available.
