That's the conclusion of a research team using data from the Microwave Limb Sounder on NASA's Upper Atmosphere Research Satellite.    FULL STORY Saturday: March 29, 2003   0410 GMT Shape of Universe seen during adolescent years Scientists using NASA's Chandra X-ray Observatory have taken a snapshot of the adolescent Universe from about five billion years ago when the familiar web-like structure of galaxy chains and voids first emerged.    FULL STORY A gamma-ray burst bonanza ESA's Integral satellite is detecting gamma-ray bursts at a rate of nearly one per day, establishing itself as a key player in the hunt for these enigmatic explosions. Launched in October 2002, Integral has just captured four bursts in the last four months right in the middle of its field of view.    FULL STORY Friday: March 28, 2003   0930 GMT Japan enters spy satellite arena with rocket launch Breaking from over 30 years of strict non-military use of the high frontier, Japan launched its first pair of reconnaissance satellites Friday that will serve as spying eyes to keep tabs on neighboring North Korea.    FULL STORY Teams studying Columbia data recorder tape A preliminary review of Columbia's OEX data recorder indicates that potential data may exist as late as 9:00:18 a.m. EST on Feb. 1. That would be several seconds after the last known data received on the ground from Columbia and just moments before the vehicle broke apart.    INVESTIGATION STATUS CENTER    TIMELINE OF COLUMBIA'S FINAL HOUR Video coverage for subscribers only:    VIDEO: COLUMBIA DATA RECORDER ARRIVES AT KSC QT    MORE COLUMBIA INVESTIGATION VIDEO    SUBSCRIBE NOW Thursday: March 27, 2003   0204 GMT Foam impact centered on panel 6 of wing's edge Engineers hope to begin analyzing data this weekend from a recovered tape recorder that stored readings from some 721 sensors throughout the shuttle Columbia during its final 45 minutes of flight. Analysts hope the data will help them precisely map out the flow of hot gas through the doomed ship's left wing to confirm and refine - or possibly modify - current theories about where the initial breach occurred and how the deadly plume then worked its way through the interior of the wing.    FULL STORY Video coverage for subscribers only:    VIDEO: NASA OFFICIALS TESTIFY ON DEBRIS COLLECTION QT    VIDEO: EXPERTS DISCUSS DEBRIS ANALYSIS, RECONSTRUCTION QT    VIDEO: COLUMBIA ACCIDENT BOARD NEWS CONFERENCE QT    SUBSCRIBE NOW Launch to replenish U.S. Global Positioning System With war raging half-a-world away, a routine but crucial rocket launch from Florida next week will deploy a fresh tactical navigation satellite into the U.S. military's Global Positioning System -- the orbiting network that ground, air and sea forces rely upon for guidance.    FULL STORY Stunning Hubble images of mysterious erupting star In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star has long since faded back to obscurity, but observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" have uncovered remarkable new features.    FULL STORY Wednesday: March 26, 2003   0420 GMT Expert says NASA lost sight of safety margin An independent aerospace expert told the Columbia Accident Investigation Board Tuesday NASA managers somehow missed the obvious when it came to the potential threat of foam debris falling off the space shuttle's external fuel tank.    FULL STORY Video coverage for subscribers only:    VIDEO: DIRECTOR OF KENNEDY SPACE CENTER TESTIFIES QT    VIDEO: CHIEF OF SHUTTLE PROCESSING SAFETY IS QUESTIONED QT    VIDEO: TECHNICAL AND MANAGEMENT CONSULTANT APPEARS QT    SUBSCRIBE NOW Main search for wreckage passes halfway mark As the search of more than 500,000 acres of primary recovery area for Space Shuttle Columbia material reached its halfway mark, NASA Administrator, Sean O'Keefe, visited key sites in east Texas to thank recovery crews for their diligence and hard work.    FULL STORY Doomed matter near black hole gets 2nd lease on life Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say.    FULL STORY Tuesday: March 25, 2003   0622 GMT New class of hot-tempered black holes bucks trends NASA scientists have found two smoking-gun features of an intermediate-mass black hole that suggest these newly identified objects are fundamentally different from other types of black holes, running hotter than expected.    FULL STORY Gamma-ray burst, supernova link confirmed Scientists announced Monday that they have used NASA's Chandra X-ray Observatory to confirm that a gamma-ray burst was connected to the death of a massive star. This result is an important step in understanding the origin of gamma-ray bursts, the most violent events in the present-day Universe.    FULL STORY Recovered data tape in relatively good condition Magnetic tape inside a data recorder recovered last week in Texas appears to be in remarkably good shape. Engineers are increasingly optimistic about recovering potentially valuable data from the salvaged tape that could shed additional light on the aerodynamic forces and temperatures the shuttle experienced during its final minutes.    FULL STORY Long-term planning process for shuttle being developed NASA is taking new steps to ensure Space Shuttles fly safely into the future. Last week, during the first of what will be an annual Service Life Extension Program Summit, NASA led the U.S. space flight community in a comprehensive debate on the long-term requirements to extend the life of the Space Shuttle fleet.    FULL STORY Video coverage for subscribers only:    VIDEO: NEWS CONFERENCE ON SHUTTLE LIFE EXTENSION EFFORTS QT    SUBSCRIBE NOW Monday: March 24, 2003   0224 GMT Rocket troubles delay pair of ESA research projects The problems experienced by the Ariane 5 rocket program since its failure last year have impacted a pair of European science missions -- one to explore a comet, the other to orbit our moon -- that were due to launch in the first half of 2003.    FULL STORY				News Archive March 17-23: Columbia data recorder recovered; could hold key insights; Hearing focuses on debris, breakup mechanics; NASA's Columbia mishap team reorganized; Weighing a black hole at the edge of the universe; Race to gamma ray burst reveals gigantic explosion.
