WASHINGTON, Oct. 27 /PRNewswire/ -- A milestone has been achieved, the first flight of Lockheed Martin's (NYSE: LMT) Tactical Reconnaissance and Counter-Concealment-Enabled Radar (TRACER) aboard an MQ-9 Unmanned Aerial System. The milestone also marks the first time a penetrating radar has flown on a fixed wing unmanned aerial system. TRACER, a dual-band synthetic-aperture radar (SAR), detects vehicles, buildings and other man-made objects that are buried, camouflaged or concealed...

A further campaign to support the development of the candidate Earth Explorer BIOMASS mission recently took place in Sweden. The campaign set out to demonstrate how the mission would be able to monitor changes in forest biomass over time. The BioSAR 2010 campaign is the third of its kind, building on two similar experiments to show how spaceborne radar could map stocks of boreal forest. Another campaign was also carried out in French Guiana in 2009 to demonstrate the value of the...

Scientists are crediting satellite imagery with helping to predict where volcanic eruptions could strike. It is well known that earthquakes can stress Earth's crust and trigger subsequent quakes, but there has been no proof of this for volcanoes until now. In September 2005, a volcanic event in Ethiopia's Afar Desert forced magma up through rocks in a crack, known as a dyke, resulting in a 60-km-long tear in Earth's crust. Over the next four years, 12 more dykes were created in the same...

The magnitude 7.0 earthquake that caused more than 200,000 casualties and devastated Haiti's economy in January resulted not from the Enriquillo fault, as previously believed, but from slip on multiple faults -- primarily a previously unknown, subsurface fault -- according to a study published online this week in Nature Geoscience.In addition, because the earthquake did not involve slip near Earth's surface, the study suggests that it did not release all of the strain that has built up on...

Devastating around a third of the country, it is estimated that the floods in Pakistan have affected up to 20 million people. As part of the effort to support humanitarian relief, satellite data are being used to generate essential maps of the flooded areas. Pakistan's floods are arguably the worst in living memory, leaving many hundreds dead and millions homeless or marooned as villages and infrastructure have washed away. The fear now is that more will die from water-borne diseases. The...

New NASA airborne radar images of Southern California near the U.S.-Mexico border show Earth's surface is continuing to deform following the April 4 magnitude, 7.2 temblor and its many aftershocks that have rocked Mexico's state of Baja California and parts of the American Southwest."¨"¨The data, from NASA's airborne Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), reveal that some faults in the area west of Calexico, Calif., have continued to move at Earth's surface,...

An award-winning new website is using realtime imagery from ESA's Envisat satellite to provide a wealth of information on sea ice to aid safe passage through the treacherous waters of the Antarctic. Although remote, the Southern Ocean is an increasingly busy route for sea traffic. These seas are used more and more to conduct scientific research, transport freight, harvest fertile fishing grounds and carry tourists to experience one of Earth's last wildernesses. However, ever-changing pack ice...

On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake-level changes on Saturn's largest moon, Titan"”the only other place in the solar system seen to have a hydrological cycle with standing liquid on the surface. Using data gathered by NASA's Cassini spacecraft over a span of four years, the...

This Envisat radar image acquired over the Gulf of Mexico on June 22, 2010 shows that the oil spill (outlined in white) has radiated all over the Gulf of Mexico basin and is also continuing to feed into the Loop Current (red arrow). "This is a new piece of evidence of the seemingly strong attracting power of the intense Loop Current in this area," said Dr Bertrand Chapron of Ifremer, the French Research Institute for Exploitation of the Sea. "Based on the striking analogy between...

Scientists monitoring the US oil spill with ESA's Envisat radar satellite say that it has entered the Loop Current, a powerful conveyor belt that flows clockwise around the Gulf of Mexico towards Florida. "With these images from space, we have visible proof that at least oil from the surface of the water has reached the current," said Dr Bertrand Chapron of Ifremer, the French Research Institute for Exploitation of the Sea. Dr Chapron and Dr Fabrice Collard of France's CLS have been combining...

Endeavour launched from Kennedy Space Center on April 9. 1994 at 7:05 AM EDT and landed at Edwards AFB on April 20 at 9:54 AM PDT. The shuttle orbited 183 times at an altitude of 121 nautical miles at an inclination of 57 degrees and travelled 4.7 million miles. The mission lasted  11 days, 5 hours, 49 minutes, and 30 seconds. The primary payload was the Space Radar Laboratory (SRL-1), located in payload bay; activated by crew and operated by teams on ground. SRL-1 included the Spaceborne...
