NASA tests most powerful booster rocket ever (anglès) - Dc, 01/09/2010 - 19:10
Washington (AFP) Aug 31, 2010
NASA and aerospace company ATK Aerospace Systems successfully tested Tuesday the most powerful solid-fuel rocket engine ever, even though its future in the space program remains in doubt. A huge roar and massive flames accompanied the two-minute "static" or non-flight test of the five-segment DM-2 (Demonstration Motor 2) rocket booster in the western desert state of Utah. The DM-2 was de

The Moon Puts On Camo (anglès) - Dc, 01/09/2010 - 19:10
Greenbelt MD (SPX) Aug 31, 2010
A new geologic map of the moon's Schrodinger basin paints an instant, camouflage-colored portrait of what a mash-up the moon's surface is after eons of violent events. The geologic record at Schrodinger is still relatively fresh because the basin is only about 3.8 billion years old; this makes it the moon's second-youngest large basin (it's roughly 320 kilometers, or 200 miles, in diameter).

Ice Cloud And Land Elevation Mission Comes To An End (anglès) - Dc, 01/09/2010 - 19:10
Washington DC (SPX) Aug 31, 2010
One of NASA's orbiting sentinels is expected to return to Earth in a few days. The agency's Ice, Cloud, and land Elevation (ICESat) satellite completed a very productive scientific mission earlier this year. NASA lowered the satellite's orbit last month and then decommissioned the spacecraft in preparation for re-entry. It is estimated that the satellite will re-enter the Earth's atmospher

El Segundo CA (SPX) Aug 31, 2010
Boeing has announced that the first of 12 Global Positioning System (GPS) IIF satellites the company is building for the U.S. Air Force has entered service. GPS IIF-1 is the newest member of the active 31-satellite GPS constellation, which provides accurate navigation, positioning and timing information to more than 1 billion military and civilian users around the world. GPS IIF satellites

Catch A Falling Star (anglès) - Dc, 01/09/2010 - 19:10
Sydney, Australia (SPX) Aug 31, 2010
Every year, the world is treated to several well-known meteor showers. The Leonids, Draconids, Perseids and others usually get mentioned in the mainstream media, giving the general public a taste of just how much material flies at our planet from space. The predictable, regular showers are produced by debris from the tails of comets, and astronomers have been able to link certain events to

Alpha Magnetic Spectrometer Makes Last Stop On Earth (anglès) - Dc, 01/09/2010 - 19:10
Cape Canaveral FL (SPX) Aug 31, 2010
A new experiment designed to reveal the origin and structure of the universe has reached its last stop on Earth before it's set to ride into orbit aboard space shuttle Endeavour early next year. The long-awaited Alpha Magnetic Spectrometer-2 (AMS) arrived Aug. 26 at NASA's Kennedy Space Center in Florida, secured in the belly of a U.S. Air Force C-5M cargo plane that arrived at the launch

Bonn, Germany (SPX) Aug 30, 2010
For a month now, we have been acquiring altitude models with the TanDEM-X and TerraSAR-X satellite pair. Already, over 1000 products have come out of our operational processing chain. Alongside many test images, some of the data also give an insight into how humankind has shaped the surface of the Earth - and how the highs and lows around them have determined the course of their lives. Man

Distant Star's Sound Waves Reveal Cycle Similar To Sun (anglès) - Dc, 01/09/2010 - 19:10
Washington DC (SPX) Aug 30, 2010
In a bid to unlock long-standing mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star. By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the sun's solar cycle. Results of the study, conducted by scientists at the U.S. National Center for Atmospheric
