KENNEDY SPACE CENTER, FLA. -- On Launch Pad 39A, the doors begin closing on space shuttle Discovery's payload bay. Seen inside the bay are the payloads, the U.S. Node 2, named Harmony (lower), and orbital docking system (upper). Mission STS-120 will bring the Harmony module that will provide attachment points for European and Japanese laboratory modules to the International Space Station. Launch of Discovery is targeted for Oct. 23. Photo credit: NASA/George Shelton KSC-07pd2682

CAPE CANAVERAL, Fla. -- Repair work to space shuttle Discovery's external fuel tank begins in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Technicians will modify 32 support beams, called stringers, on the tank's intertank region by fitting pieces of metal, called radius blocks, over the stringers' edges where they attach to the thrust panel area. The thrust panel is where the tank meets the two solid rocket boosters and sees the most stress during the flight into orbit. After the modifications and additional scans of the stringers are complete, foam insulation will be re-applied. Discovery's next launch opportunity to the International Space Station on the STS-133 mission is no earlier than Feb. 3, 2011.

Successful MPPF Pneumatics Verification and Validation Testing

description

Summary

Engineers and technicians completed verification and validation testing of several pneumatic systems inside and outside the Multi-Payload Processing Facility (MPPF) at NASA's Kennedy Space Center in Florida. In view is the service platform for Orion spacecraft processing. The MPPF will be used for offline processing and fueling of the Orion spacecraft and service module stack before launch. Orion also will be de-serviced in the MPPF after a mission. The Ground Systems Development and Operations Program (GSDO) is overseeing upgrades to the facility. The Engineering Directorate led the recent pneumatic tests.
