NASA's GLAST Satellite Gets Twin Solar Panels in Prep for Launch
Preparations for launching NASA's Gamma-ray Large Area Telescope (GLAST) satellite are underway at NASA's Kennedy Space Center (KSC), Fla. NASA KSC's "NASA Expendable Launch Vehicle Status Report" on Thursday, March 20, noted that GLAST's twin solar panels have been attached. The panels will provide electrical power for GLAST after its launch into earth orbit.
As part of the process for preparing GLAST for launch, the satellite's various components are tested and re-tested. During the week of March 24, solar panel deployment and solar panel lighting were tested. Comprehensive performance tests were also done, that included end-to-end communications testing through the Tracking and Data Relay Satellite (TDRS) system.
At Pad 17-B on Cape Canaveral Air Force Station, buildup of the Delta II rocket began Monday, March 24, with the hoisting of the first stage. Work to attach the nine strap-on solid rocket boosters followed. Stacking of the second stage is currently planned for April 3.
GLAST is slated for launch aboard a Delta II 7920-H rocket from the Cape Canaveral Air Station on May 16. The window for launch runs between 11:45 a.m. – 1:40 p.m. EDT.
GLAST is a powerful space observatory that will explore the most extreme environments in the Universe, where nature harnesses energies far beyond anything possible on Earth. It will search for signs of new laws of physics and what composes the mysterious Dark Matter, explain how black holes accelerate immense jets of material to nearly light speed, and help crack the mysteries of the stupendously powerful explosions known as gamma-ray bursts.
NASA’s GLAST mission is an astrophysics and particle physics partnership, developed 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 United States.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
