KENNEDY SPACE CENTER, Fla. -- An L-1011 aircraft called the Stargazer lands at the Skid Strip, Cape Canaveral Air Force Station. Underneath its belly it carries the Orbital Sciences Corp. Pegasus XL launch vehicle with the High Energy Solar Spectroscopic Imager (HESSI) attached. The Pegasus XL will launch the HESSI no earlier than June 12 from CCAFS. The primary mission of HESSI is to explore the basic physics of particle acceleration and energy release in solar flares KSC-01pp1062

KENNEDY SPACE CENTER, FLA. -- NASA's Galaxy Evolution Explorer spacecraft is successfully rotated to horizontal in preparation for mating with the Pegasus XL launch vehicle. The GALEX, set to launch April 2 from Cape Canaveral Air Force Station, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. From its orbit high above Earth, the spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors. Looking in the ultraviolet will single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength. These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd0624

KENNEDY SPACE CENTER, FLA. -- In the Multi-Payload Processing Facility, NASA's Galaxy Evolution Explorer is prepared for mating with the Pegasus XL launch vehicle. The GALEX, set to launch April 2 from Cape Canaveral Air Force Station, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. The spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors to single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength. These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd0741

KENNEDY SPACE CENTER, FLA. - A worker makes adjustments on the Galaxy Evolution Explorer (GALEX) spacecraft during the second mating with the Pegasus XL launch vehicle. The March 26 launch was delayed to enable protective covers to be added to the Optical Wheel Assembly (OWA) on GALEX to avoid the possibility of a missing electrical cable fastener floating into and jamming the mechanism when GALEX is in orbit. Launch of GALEX is now scheduled for no earlier than April 26. KSC-03pd0999
