In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, technicians attach straps from a crane in order to lift the Science Instrument Command and Data Handling Unit, or SIC&DH. The SIC&DH will be installed on the Hubble Space Telescope during space shuttle Atlantis' STS-125 mission. This unit will replace the one that suffered a failure aboard the orbiting telescope on Sept. 27, 2008. The SIC&DH is being prepared for integration onto the Multi-Use Lightweight Equipment Carrier. The carrier holds the payload for space shuttle Atlantis' STS-125 mission servicing NASA's Hubble Space Telescope, targeted to launch May 12. Photo credit: NASA/Jack Pfaller
