Workers are constructing flight support system FSS access scaffolding carriers for the STS-125 servicing mission 4.

In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center, workers are constructing flight support system (FSS) access scaffolding that will be used to prepare the Hubble Space Telescope, or HST, carriers for the STS-125 servicing mission 4. The FSS will berth, secure and furnish power to Hubble and also contains the soft capture mechanism to be attached to the telescope. Upon completion of STS-125, the Hubble will provide even deeper and more detailed views of the Universe. The STS-125 mission will be the final space shuttle mission to the Hubble Space Telescope.
