Jason-3 will extend the two-decade series of satellites that are tracking global sea level changes and enabling more accurate weather, ocean and climate forecasts. The thr]]> Fri, 24 MAY 2013 11:54:36 AEST Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset. For the devastating Japan 2011 event, the team reveals that the analysis of the GPS data and issue of a detailed tsunami alert would have tak]]> Fri, 24 MAY 2013 11:54:36 AEST Success on the battlefield requires warfighters to know as much as possible about themselves, their surrounding environment and the potential threats around them. Dismounted infantry squads in particular risk surprise and loss of tactical advantage over opponents when information is lacking. While squads use many different technologies to gather and share information, the current piecemeal]]> Fri, 24 MAY 2013 11:54:36 AEST Success on the battlefield requires warfighters to know as much as possible about themselves, their surrounding environment and the potential threats around them.

Once one of the largest seas in the world, it shrunk to a tenth of its original volume after Russia diverted its feeder rivers in the 1960s. Scientists studying the Aral Sea's changing ecology and retreating shoreline have looked to Landsat - and a new feature of the Landsat Data Continuity Mission ]]> Fri, 24 MAY 2013 11:54:36 AEST Google has followed in the footsteps of Charles Darwin to gather images of the beauty and biological diversity of the Galapagos Islands for the Internet titan's online maps. A Google Maps team toting 360-degree cameras sticking from backpacks hiked trails, hills, and even into a live volcano to take Street View pictures of the precious environment where Darwin gleaned insights for his theory]]> Fri, 24 MAY 2013 11:54:36 AEST China has launched its first Gaofen-1 high-resolution remote sensing satellite into orbit, Xinhua news agency reported on Friday. The satellite was carried by a Long March 2D (Chang Zheng 2D) carrier rocket that blasted off from northwest China's Jiuquan Satellite Launch Center, the state news agency reported, citing China's State Administration of Science, Technology and Industry for Nati]]> Fri, 24 MAY 2013 11:54:36 AEST A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise. The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259 trillion kilograms) of mas]]> Fri, 24 MAY 2013 11:54:36 AEST Pulsars have a number of unusual qualities. Like zombies, they shine even though they're technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations. The pulsar-on-a-tabl]]> Fri, 24 MAY 2013 11:54:36 AEST ORBCOMM has announced the availability of the ORBCOMM GT 1100, a self-powered M2M asset tracking and monitoring device targeted for a variety of global markets including transportation and logistics, heavy equipment and oil and gas. ORBCOMM's ruggedized, easy-to-install device is designed to fit seamlessly in between the indented spacing on intermodal containers. Its low, one-inch height p]]> Fri, 24 MAY 2013 11:54:36 AEST Have you ever wondered what it might be like to watch the world fly by beneath you from space? That dream is elusive for most of us, but the Landsat Data Continuity Mission offers a vicarious flight with a crisper view than our eyes alone would be capable of if we were in space. That view is now available in a new NASA animation. After two months of on-orbit testing and calibration, LDCM f]]> Fri, 24 MAY 2013 11:54:36 AEST The fin whale is the second-largest animal ever to live on Earth. It is also, paradoxically, one of the least understood. The animal's huge size and global range make its movements and behavior hard to study. A carcass that washed up on a Seattle-area beach this spring provided a reminder that sleek fin whales, nicknamed "greyhounds of the sea," are vulnerable to collision when they strike]]> Fri, 24 MAY 2013 11:54:36 AEST A team of scientists has won a berth on a tiny satellite to explore one of NASA's most important frontiers in climate studies: the imbalance in Earth's energy budget and the extent to which fast-changing phenomena, like clouds, contribute to that imbalance. NASA's In-Space Validation of Earth Science Technologies ("InVEST" for short) program has funded a team led by Lars Dyrud, a scientist]]> Fri, 24 MAY 2013 11:54:36 AEST A Naval Research Laboratory instrument designed to study the Earth's thermosphere is part of a satellite mission that NASA has selected to move forward into development (Phase B), with launch expected in 2017. The NRL Space Science Division (SSD) developed Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) satellite instrument is part of NASA's Ionospheric C]]> Fri, 24 MAY 2013 11:54:36 AEST Pakistan is set to become the fifth Asian country to use China's domestic satellite navigation system which was launched as a rival to the US global positioning system, a report said Saturday. The Beidou, or Compass, system started providing services to civilians in the region in December and is expected to provide global coverage by 2020. It also has military applications.
