KENNEDY SPACE CENTER, FLA. - An oversized $434,627.40 check represents the highest amount the NASA civil service work force has ever donated to the Combined Federal Campaign. Standing with the check, from left, are Center Director Jim Kennedy; Dennis Burns, United Way of Brevard, vice president of resource development; Frank Ramsey, United Way of Brevard campaign director; Rob Rains, United Way of Brevard president; and Launch Services Program deputy director Ray Lugo, who served as KSC's Combined Federal Campaign chairperson. The check was presented at a holiday dinner and celebration at KARS Park I on Merritt Island, Fla., hosted by Center Director Jim Kennedy for NASA civil service employees. The theme of the celebration was "Launching Dreams of Those in Need." The event was sponsored by the Change Leaders Network and the Combined Federal Campaign Cabinet.

The engines will be stored at Stennis for future use on NASA's new heavy-lift rocket, the Space Launch System (SLS), which will carry NASA's new Orion spacecraft, cargo, equipment and science experiments to space.

CAPE CANAVERAL, Fla. -- Before dawn, at the Shuttle Landing Facility, or SLF, at NASA's Kennedy Space Center in Florida, space shuttle Endeavour is lowered toward the ground by the sling in the mate/demate device. Visible on Endeavour is the tail cone that covers and protects the main engines during the ferry flight. After Endeavour is on the ground, it will be towed via the two-mile tow-way from the SLF by a diesel-powered tractor to the Orbiter Processing Facility where it will begin preparations for its next mission, STS-127, targeted for May 2009.

KENNEDY SPACE CENTER, FLA. - The first stage of the Boeing Delta II rocket, slated to launch NASA's Solar Terrestrial Relations Observatory (STEREO), is lifted into a vertical position for installation into the mobile service tower at Pad 17B on Cape Canaveral Air Force Station. Preparations are under way for a liftoff no earlier than July 22. STEREO consists of two spacecraft whose mission is the first to take measurements of the sun and solar wind in 3-D. This new view will improve our understanding of space weather and its impact on the Earth. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. – Workers at Launch Complex 17-B on Cape Canaveral Air Force Station in Florida place the large patch on the Delta 2 rocket that describes the Kepler spacecraft mission to be launched by the rocket. The Kepler mission is specifically designed to survey our region of the Milky Way galaxy to discover hundreds of Earth-size and smaller planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets. Results from this mission will allow us to place our solar system within the continuum of planetary systems in the Galaxy. Photo credit: NASA/Jim Grossmann

S93-43619 (18 Aug 1993) --- At Launch Pad 39B, work is under way to remove and replace the three main engines on the Space Shuttle Discovery. Here, Rocketdyne workers Jim Tibble (left), John Mooney and Ken Bair are assisting with the removal of the first engine, main engine no. 1, using the engine vertical installer. A failed sensor in main engine no. 2 led to the shutdown of all three engines three seconds before liftoff of mission STS-51 on August 12, 1993. Because it is difficult to perform the necessary inspections, refurbishment, and retesting of a fired engine on a vehicle at the pad, NASA opted to install a fresh set of engines on Discovery.
