 Earlier this week, NASA officially rechristened GLAST - the Gamma-Ray Large Area Space Telescope - as the Fermi Gamma-ray Space Telescope. The orbital observatory was named after Italian scientist Enrico Fermi, a pioneer in high-energy physics in the first half of the twentieth century. Fermi also output it’s first complete sky map of gamma-ray emissions, which was completed in only a few days after the telescope began full operations.

 Hoping to test the Orion CEV’s parachute descent system, NASA instead ended up with a capsule mockup plummeting to the ground and giving any fake astronaut inside a real headache. The programmer parachutes, which are meant to position the capsule for a release and testing of the actual drogue parachutes (the big ones that slow the capsule’s descent), failed when the mockup was pushed out of a plane at 7600 meters (25,000 feet), causing the capsule to fall out of the sky and impact the ground at more than 200 km per hour (125 mph).

 It wasn’t exactly something that NASA had predicted early one when they chose the design for the Ares I rocket, but computer simulations of launches have shown that the shuttle booster-based vehicle would suffer from severe vibrations during launch that NASA engineers described as a “jackhammer effect.” While the shaking would not be debilitating or damaging to astronauts in the Orion CEV atop the rocket, the movement would be severe enough to prevent them from clearly reading instrument panels or pressing buttons and switches in the capsule. NASA’s solution: shock absorbers.

 Last weekend the Iranians launched a rocket in what they said was a test of a system designed to put a satellite into orbit. But according to United States military intelligence, the launch actually was an attempt to launch a satellite, and the rocket fell apart as the second stage boosted it towards space. The unusual launch took place during the night - historically and somewhat logically test launches take place during the day so that ground observers can keep tabs on the rocket and watch for anomalies.

 Speaking recently at Titusville, Florida (twenty five miles northwest of Cape Canaveral and NASA’s Kennedy Space Center), Senator Barack Obama reversed his position on NASA funding from a statement made in Denver in March of this year, when he said he would cut the space agency’s budget to finance educational reform. Now in the backyard of NASA’s most prominent facility, the Illinois senator and presumptive Democratic nominee is apparently in full support of correcting NASA’s financing woes.

 With the samples that NASA’s Phoenix Mars Lander has collected in the Martian arctic, we have been able to confirm the presence of water on Mars. However, the probe’s Microscopy, Electrochemistry and Conductivity Analyzer (MECA) is now indicating that the soil contains perchlorate, a highly oxidizing substance that would make for a harsh environment for plant life. Apart from the perchlorate, the soil is quite Earth-like in pH and mineral composition.

 Once is chance. Twice could be construed as poor planning. But three times in a row? SpaceX’s latest attempt to launch the privately funded Falcon 1 rocket ended in failure again. The two stage rocket failed to separate as designed about two minutes and twenty seconds after lift-off from the US Army Reagan Test Site on Omelek Island in the Kwajalein Atoll, which is about 4000 km (2500 miles) southwest of Hawaii in the Pacific Ocean.

 Former US Senator (D-Ohio) and astronaut John Glenn testified before the US House of Representatives late last month about the future of NASA, where he criticized President George W. Bush for directing NASA to return to the moon, but not giving the necessary funding for NASA to accomplish the goal. Glenn, a long-time advocate for NASA and space exploration, said, “I favored the [Vision for Space Exploration] because I assumed it was in addition to, not in place of, existing programs. I assumed that money requests would follow.” Thus far, none have, and any congressional attempts to increase NASA’s budget even nominally from year-to-year have been met with defeat.

 In 2004, Scaled Composite’s SpaceShipOne reached into space in the first privately funded manned space flight. The Ansari X Prize-winning flight caught the attention of the world and of Sir Richard Branson, who contracted them to build a larger version for commercial suborbital flights with Virgin Galactic. The unique carrier/spaceplane design was to be scaled up to a larger craft capable of ferrying several passengers at a time to the edge of space. The first component of this new system, the WhiteKnightTwo carrier craft, was recently unveiled by Scaled Composites.

 The National Aeronautics and Space Administration has teamed up with the non-profit digital library Internet Archive to put online a comprehensive archive of photographs and videos from the history of NASA. The new website - NASA Images.org - contains a searchable database of NASA’s 21 major image collections, including images from the Apollo program, Hubble Space Telescope, and space shuttle missions.
