GLAST Mission Coverage

    NASA Targets June 7 Launch

    The launch of NASA’s GLAST spacecraft aboard a United Launch Alliance
    Delta II rocket is now scheduled for no earlier than Saturday, June 7, during a window that extends from 11:45 a.m. to 1:40 p.m. EDT. Additional time was necessary for the Delta II launch team to assure that open engineering issues, which have been under review, are satisfactorily resolved.

    Workers at the launch pad will load the hypergolic propellants into the Delta II rocket's second stage several days prior to launch. On launch day, they will retract the mobile service tower from around the rocket at 2 a.m. Loading of the liquid oxygen, beginning the final phase of the launch countdown, is set to start
    at 10 a.m.

The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent.

    The GLAST launch team assembled May 28 in the Mission Director's Center at Cape Canaveral Air Force Station in Florida to conduct a dress rehearsal of the countdown. The previous day, technicians at the launch pad enclosed the GLAST spacecraft inside the fairing atop the Delta II rocket. The fairing serves to protect the spacecraft during its ride to space.

    GLAST: Exploring the Extreme Universe

    NASA's Gamma-Ray Large Area Space Telescope (GLAST) is a powerful space observatory that will open a wide window on the universe. Gamma rays are the highest-energy form of light, and the gamma-ray sky is spectacularly different from the one we perceive with our own eyes. With a huge leap in all key capabilities, GLAST data will enable scientists to answer persistent questions across a broad range of topics, including supermassive black-hole systems, pulsars, the origin of cosmic rays, and searches for signals of new physics.

    The mission is an astrophysics and particle physics partnership, developed by NASA in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.
