A day after a powerful magnitude 6.3 earthquake rocked Christchurch, a city of 377,000 on New Zealand's South Island, on Feb. 22, 2011, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft imaged the Christchurch region. The imaging was done at the request of the International Charter, Space and Major Disasters, which provides emergency satellite data to federal agencies in disaster-stricken regions. Two images are presented here....

Forest fires usually spread out of control very quickly. Fires that produce a lot of smoke are particularly challenging for the emergency services, because the source of the fire is then especially hard to find. A new radiometric sensor can pinpoint the heart of the flames, even when visibility is limited. The number and scale of forest fires has increased dramatically in recent decades. Who can forget last summer's television images of blazing infernos devouring miles and miles of forest in...

NASA has awarded a sole source contract to Ball Aerospace and Technology Corp. of Boulder, Colo., for the Global Precipitation Measurement Microwave Imager instrument Flight Unit 2. The Global Precipitation Measurement, or GPM, mission will use an international constellation of satellites to study global rain, snow and ice to better understand our climate, weather, and hydrometeorological processes. Under this contract, Ball Aerospace and Technology will manufacture, test and deliver the GMI...

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft captured this nighttime image of the growing oil spill in the Gulf of Mexico on May 7, 2010. On April 20, an explosion destroyed the Deepwater Horizon oil platform operating in the Gulf 80 kilometers (50 miles) offshore, resulting in substantial loss of life and releasing 5,000 barrels of oil per day into the water. The huge oil slick was being carried towards the Mississippi River...

NASA's considerable Earth-observing and data analysis and distribution capabilities have been mobilized to provide information to support disaster recovery efforts in Haiti after the devastating Jan. 12 earthquake. NASA has tasked two of its space-based, high-resolution instruments to image areas hardest hit by the earthquake. Before-and-after scenes of Port-au-Prince, for example, will be used to aid with damage assessment and recovery. The Advanced Spaceborne Thermal Emission and Reflection...

December 18, 2009, marks the tenth year since the launch of Terra, one of NASA's "flagship" Earth observing satellites. But the decade is more than just a mechanical milestone. With each additional day and year that the satellite monitors Earth, scientists achieve a lengthened record of Earth's vital signs. It's that record that helps scientists assess the health of Earth's ocean, land, and atmosphere, and determine how these systems are changing. "Earth system science is a relatively young...

The system has an important part in the global climate due to its size, its high latitude location and the negative radiation balance of its large ice sheets. Antarctica has also been in focus for several decades due to increased ultraviolet (UV) levels caused by stratospheric ozone depletion, and the disintegration of its ice shelves. During the summer of 1997-1998, measurements of beam absorption and beam attenuation coefficients, and downwelling and upwelling irradiance were made in the...

The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while newer ones used semiconductors and superconductors as the absorptive elements. Bolometers can...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
