“WASHINGTON, Aug. 11 /PRNewswire-USNewswire/ — NASA has assigned the crew for space shuttle mission STS-134 to the International Space Station. The flight will deliver the Alpha Magnetic Spectrometer, or AMS, to the station. The AMS is a state-of-the-art cosmic ray particle physics detector designed to examine fundamental issues about matter and the origin and structure of the universe.”
“SUNNYVALE, Calif., March 21 /PRNewswire/ — The fourth and final pair of massive solar arrays, built by Lockheed Martin (NYSE: LMT) at its Space Systems facility in Sunnyvale, have been installed on the International Space Station by the crew of the space shuttle Discovery. The two new arrays have been deployed and are generating electricity.”
“FLYBY ALERT: In a twilight launch of stunning beauty, space shuttle Discovery left Earth last night on a two week construction mission to the International Space Station (ISS). Discovery is now approaching the ISS for docking on March 17th. The timing of this mission favors sky watchers in North America and Europe who will be able to see the two spacecraft flying over many towns and cities in the evenings ahead. Tonight, March 16th, is extra-special because the not-yet-docked duo will appear as distinct points of bright light flying one after the other through the twilight sky–a rare “double flyby.” Check the Simple Satellite Tracker for flyby times: http://spaceweather.com/flybys .”

“MINNEAPOLIS, March 10 /PRNewswire-FirstCall/ — Alliant Techsystems (NYSE: ATK) successfully conducted the first test firing of the igniter that will be used on NASA‘s Ares I first stage. Today’s test at ATK’s Promontory, Utah facility generated a flame almost 200 feet in length. When ignited inside the world’s largest solid rocket booster, this flame will trigger the liftoff of the rocket that will send future astronauts into orbit. Today’s test prepares the way for the first ground test of the fully-developed Ares I first stage, a five-segment derivative of the Space Shuttle Reusable Solid Rocket Motor, scheduled for next fall.
The Ares I igniter is the same flight-proven design used on the Shuttle’s Solid Rocket Boosters (SRBs). This igniter, however, takes advantage of upgraded materials to provide higher performance in the liner and insulation. The new liner thermal properties are equivalent to those of the shuttle, but its stress/strain capability is 100 percent greater. The new insulation is also 20 percent lighter than the insulation currently on the Space Shuttle fleet, providing valuable weight savings and higher performance. Initial data showed the igniter performed as expected.”
