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 U.S. and Japanese space agencies have produced a digital topographic map of Earth that covers more of our planet than ever. The map was created from nearly 1.3 million individual stereo-pair images collected by the Japanese Advanced Spaceborne Thermal Emission and Reflection Radiometer that's aboard NASA's Terra satellite. This is the most complete, consistent global digital elevation data yet made available to the world, said Woody Turner, NASA program scientist. Mike Abrams, 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...
