In this fish-eye view, a worker oversees the movement of the Chandra X-ray Observatory into the payload bay of the orbiter Columbia. Chandra is the primary payload on mission STS-93, scheduled to launch no earlier than July 20 aboard Space Shuttle Columbia. 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
