NASA’s Jet Propulsion Laboratory uses new Radar Instrument to montior Levees in California

NASA - National Aeronautics and Space AdministrationPasadena, CA – One morning in 2008, research scientist Cathleen Jones of NASA’s Jet Propulsion Laboratory in Pasadena, CA, was flying over the San Andreas fault near San Francisco, testing a new radar instrument built at JPL.

As the plane banked to make a turn, she looked down to see the Sacramento River delta, a patchwork of low-lying lands crisscrossed by levees.

Jones was using an instrument that can measure tiny movements of the ground on the scale of less than half an inch (less than a centimeter). It’s called the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR).

This 2004 levee break, caused by a burrowing beaver, did $90 million worth of damage. NASA's UAVSAR is monitoring levees for early signs of stress that could lead to failure. (Calif. DWR)

NASA creates 3D Image of Los Angeles Earthquake Zone

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On March 28th, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California.

There have been hundreds of aftershocks, including one of magnitude 4.1.

JPL scientists modeled the March 28, 2014 magnitude 5.1 quake near Los Angeles based on USGS seismic data. This model image shows how the quake may appear to airborne radar, such as NASA's UAVSAR, which will survey the area soon. Blue shades indicate the greatest surface displacement.

NASA looks into reducing the noise of a Sonic Boom for Supersonic Passenger Flight

 

Written by Frank Jennings, Jr.
NASA Glenn Research Center

NASA - National Aeronautics and Space AdministrationCleveland, OH – Since the Concorde’s final landing at London’s Heathrow Airport nearly a decade ago, commercial supersonic air travel has been as elusive as a piece of lost luggage. However, this hasn’t stopped NASA from continuing the quest to develop solutions that will help get supersonic passenger travel off the ground once more.

And, while aerospace engineers have made significant progress in their understanding of supersonic flight, one significant challenge remains: the loud sonic boom.

NASA uses satellites, aircraft, and high-altitude balloons to investigate California’s extreme drought

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – California is supposed to be the Golden State.  Make that golden brown.

The entire west coast of the United States is changing color as the deepest drought in more than a century unfolds.  According to the U.S. Department of Agriculture and NOAA, dry conditions have become extreme across more than 62% of California’s land area—and there is little relief in sight.

Union of Concerned Scientists Survey Finds Many Households Can Use Electric Vehicles

 

4 out of 10 Households Can Switch With Little or No Change to Driving Habits

Union of Concerned ScientistsWashington, D.C. – Four out of 10 households could use an electric vehicle with little or no change to their driving habits and vehicle needs, according to a national survey released by the Union of Concerned Scientists and Consumers Union.

While less than 1 percent of the country are driving electric vehicles (EVs) today, the survey found 42 percent of respondents with cars — equivalent to 45 million households when applied nationally — meet the basic criteria for using plug-in hybrid electric vehicles like the Chevy Volt.

If everyone who could use an EV had one today, we would save 350 million barrels of oil a year. «Read the rest of this article»
