NASA is launching the Gamma-Ray Large Area Space Telescope (GLAST) no earlier than June 3rd. GLAST is an observatory that will study gamma rays, the highest-energy form of light in the electromagnetic spectrum. The gamma ray sky is very different from the sky seen in visual light. GLAST’s main mission objectives are: to understand the mechanisms of particle acceleration in active galactic nuclei (AGNs), neutron stars, and supernova remnants (SNRs); resolve the gamma-ray sky by characterizing unidentified sources and diffusing emissions; determine the high-energy behavior of gamma-ray bursts (GRBs) and variable sources; probe dark matter and the early universe. GLAST will help scientists study supermassive black hole systems, pulsars, and the origin of cosmic rays. GLAST will search for signatures of new physics. GLAST is called the “Mission to Explore the Extreme Universe”. GLAST is a combined effort between NASA and the U.S. Department of Energy, along with important contributions from academic institutions in France, Germany, Italy, Japan, Sweden, and the United States.

On June 15th, NASA plans to launch the JPL OSTM/Jason-2 spacecraft from Vandenberg Air Force Base in California using a United Launch Alliance Delta II 7320 rocket. Jason-2 will follow the same orbital path as Jason. For 3 years, the Jason-2 will study oceanic surface topography measurements and determine the variability of ocean circulation. Jason-2 data will improve the measurements of time-averaged ocean circulation, global sea-level change, and open ocean tide models. Jason-2 has many sophisticated sensors to complete its many functions. Its orbit will cover 95% of ice-free oceans every 10 days. It will keep in constant communication using the NOAA Tracking Stations in Alaska and Wallops Island, Virginia with a EUMETSAT Station in Usingen, Germany.
