New space observations reveal that since October 2003, the aquifers for California's primary agricultural region -- the Central Valley -- and its major mountain water source -- the Sierra Nevadas -- have lost nearly enough water combined to fill Lake Mead, America's largest reservoir. The findings, based on data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace), reflect California's extended drought and increased rates of groundwater being pumped for human...

You don't always have to have a rocket to do rocket science. Sometimes a mere airplane will do "“ that is, a mere Boeing 747 toting a 17-ton, 9-foot wide telescope named SOFIA. Short for Stratospheric Observatory for Infrared Astronomy, SOFIA will observe the universe while gliding through the stratosphere at 45,000 feet. When it begins operations next year, it will be the world's biggest, most advanced airborne observatory. "SOFIA is set to achieve some spectacular science," says...

By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale "“ and the findings look promising. Scientists merged monthly total ozone data derived from the vertically downward-looking measurements of the GOME instrument on ESA's ERS-2 satellite, SCIAMACHY on ESA's Envisat and GOME-2 on the European Meteorological Satellite Organization's...

A team of international scientists led by Mirjam Langhans, from the German Aerospace Center (DLR), will present first results of a global analysis of spatial patterns, occurrence and origin of river channels on Titan at the European Planetary Science Congress in Potsdam, Germany, on Wednesday September 16. To date scientists have focused their investigations on single channels due to the fact that radar and spectral data have only been captured for some narrow areas of the surface below the...

NASA has awarded a contract modification to L-3 Communications Integrated Systems, L.P., of Waco, Texas, for further developmental engineering in support of the Stratospheric Observatory for Infrared Astronomy mission, known as SOFIA. This option modification under the base contract L-3 currently holds extends the period of performance through Dec. 31, 2009. The option is valued at approximately $8.7 million, bringing the total value of the contract to about $37.7 million. The initial...

Today the new call for proposals for student experiments to be flown on two REXUS sounding rockets and two BEXUS stratospheric balloons opens. Selected student teams will have the opportunity to design and build an experiment suitable for a flight on the BEXUS 10 and 11 balloons or the REXUS 9 and 10 sounding rockets. The BEXUS (Balloon-borne Experiments for University Students) 10 and 11 balloons will be launched in September 2010 and the REXUS (Rocket-borne Experiments for University...

On Tuesday, the world's first piloted fuel cell powered aircraft took off from an airfield in Germany, leaving zero carbon dioxide emissions in its wake. "We have improved the performance capabilities and efficiency of the fuel cell to such an extent that a piloted aircraft is now able to take off using it," said Johann-Dietrich Woerner from the German Aerospace Center (DLR). "This enables us to demonstrate the true potential of this technology, also and perhaps specifically for applications...

The 2008 ozone hole "“ a thinning in the ozone layer over Antarctica "“ is larger both in size and ozone loss than 2007 but is not as large as 2006. Ozone is a protective atmospheric layer found in about 25 kilometers altitude that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays, which can increase the risk of skin cancer and cataracts and harm marine life. This year the area of the thinned ozone layer over the South Pole reached about 27 million...

About four billion years ago, there were lakes on Mars which may have been fed by short-lived rivers that were, in turn, fed by precipitation. These lakes filled craters that were formed by the impact of meteorites. Water accumulated in places where rivers broke through the crater rims. Deltas were formed at the mouths of the rivers, similar to how they are formed where rivers flow into lakes or seas on Earth. These are the findings of an international team of researchers led by Ernst Hauber...
