Donald Savage<br />Headquarters, Washington July 9, 2002<br />(Phone: 202/358-1547)<br /><br />Nancy Neal<br />Goddard Space Flight Center, Greenbelt, Md.<br />(Phone: 301/286-0039)<br /><br />RELEASE: c02-s<br /><br />NASA MODIFIES LOCKHEED CONTRACT TO SUPPORT <br />FINAL HUBBLE SPACE TELESCOPE SERVICING MISSION<br /><br /> Lockheed Martin Space Systems Company's Missiles and <br />Space Operations, Sunnyvale, Calif., has received a contract <br />modification valued at $123 million from NASA's Goddard <br />Space Flight Center, Greenbelt, Md., for work to be <br />performed in support of Servicing Mission 4, the final <br />servicing mission to the Hubble Space Telescope. Servicing <br />Mission 4 is scheduled for February 2004,<br /><br />Under terms of the contract, Lockheed will be responsible <br />for implementing the Servicing Mission 4 and for post-<br />servicing-mission observatory-verification efforts to ensure <br />the newly installed equipment is working properly and the <br />telescope is ready to resume its scientific observations. <br /><br />Lockheed and its subcontractors will be responsible for <br />designing, building, testing and integrating the new systems <br />into Hubble, including new batteries, new gyroscopes and a <br />new Aft Shroud Cooling System. The new cooling system will <br />carry heat away from scientific instruments and allow the <br />instruments to operate better at lower temperatures. It also <br />will allow multiple instruments to operate simultaneously, <br />helping the science team maintain the program's high <br />productivity. <br /><br />Hubble's remaining original Fine Guidance Sensor (FGS) also <br />will be changed out during the flight. Hubble has three of <br />these sensors, which are systematically refurbished and <br />upgraded in "round-robin" fashion, one per servicing <br />mission. By the conclusion of SM4 all three FGSs will have <br />been brought up to optimum condition. <br /><br />Lockheed also will be responsible for the integration of two <br />new science Instruments to be installed on the SM 4 flight: <br />the Cosmic Origins Spectrograph and the Wide Field Camera <br />Three. <br /><br />The Hubble Space Telescope Program is managed by Goddard for <br />the Office of Space Science at NASA Headquarters, <br />Washington.<br /><br />More information about the Hubble Space Telescope can be <br />found at:<br />http://hubble.nasa.gov<br /><br /> -end-
