Chandra X-Ray Observatory

KENNEDY SPACE CENTER, FLA. -- Inside the Vertical Processing Facility, the Chandra X-ray Observatory is lifted by an overhead crane in order to transfer it into the payload canister transporter and out to Launch Pad 39B. Chandra is scheduled to launch no earlier than July 20 at 12:36 a.m. EDT aboard Space Shuttle Columbia, on mission STS-93. With the world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high- temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe.
