Technicians in the Payload Changeout Room at Launch Pad 39B are removing the batteries from the Hubble Space Telescope for recharging. The two sets of six batteries apiece will be taken to the battery lab inside the Vehicle Assembly Building for 130 hours of recharging, and then reinstalled in the telescope. The recharging became necessary when the first launch attempt of Space Shuttle Mission STS-31 was scrubbed April 10. A second try is set for April 24 at 8:31 a.m. EDT.
