Satellites to support NASA's hurricane research

NASA contracted the Spanish HISPASAT Group, to which the Spanish satellite telecommunications operator HISPASAT and the Brazilian operator HISPAMAR both belong, to provide satellite communications in support of the Hurricane and Severe Storm Sentinel HS3 mission, using the Amazonas 2 satellite and NASA´s Global Hawk UAVs. This mission is specifically targeted to investigate the processes of underlying hurricane formation and intensity change in the Atlantic Ocean basin.

GPM Microwave Imager Instrument for NASA and JAXA Mission Arrives at Goddard

The Global Precipitation Measurement Microwave Imager (GMI) instrument has arrived at NASA's Goddard Space Flight Center in Greenbelt, Md. for integration into NASA's upcoming Earth science spacecraft. The instrument was built at the Ball Aerospace and Technologies Corp., Boulder, Colo. Engineers at NASA Goddard will integrate both the GMI and the Dual-frequency Precipitation Radar (DPR) onto the main body of the Global Precipitation Measurement (GPM) mission's core satellite. After extensive testing, the satellite will then be shipped to Japan for launch in 2014.

NASA Awards Cooperative Agreement for Earth Science Research

NASA has awarded a cooperative agreement to the Bay Area Environmental Research Institute of Sonoma, Calif., to support Earth science research at NASA's Ames Research Center at Moffett Field, Calif. The Ames Cooperative for Research in Earth Science and Technology (ARC-CREST) agreement has a total value of approximately $137 million, which will be funded annually up to $14 million. The 10-year agreement covers the period from March 1, 2012 through Feb. 28, 2022.

Next-Gen Weather Satellites To Improve Tornado Warnings

On Jan. 22 and 23, 2012, more than 37 tornadoes struck the southern USA. Ten of them tore across the Lower Mississippi Valley into Alabama. Worst hit were St. Clair and Jefferson County, Ala., where 2 people were killed, about 100 others injured, and at least $30 million in damage was done. It was a chilling reminder of the April 2011 onslaught of deadly tornadoes that took a staggering toll across southern and Midwestern states. In southern parts of the USA, tornado season tends to peak in springtime.

NASA pinning down 'here' better than ever

Before our Global Positioning System (GPS) navigation devices can tell us where we are, the satellites that make up the GPS need to know exactly where they are. For that, they rely on a network of sites that serve as "you are here" signs planted throughout the world. The catch is, the sites don't sit still because they're on a planet that isn't at rest, yet modern measurements require more and more accuracy in pinpointing where "here" is. To meet this need, NASA is helping to lead an international effort to upgrade the four systems that supply this crucial location information.

NASA Landsat's Thermal Infrared Sensor Arrives at Orbital

A new NASA satellite instrument that makes a quantum leap forward in detector technology has arrived at Orbital Sciences Corp. in Gilbert, Ariz. There it will be integrated into the next Landsat satellite, the Landsat Data Continuity Mission (LDCM). The Thermal Infrared Sensor (TIRS) will take the Earth's temperature with a new technology that applies quantum physics to detect heat. The engineering team at NASA's Goddard Space Flight Center in Greenbelt, Md., completed TIRS on an accelerated schedule, going from plans on paper to building the instrument in an unprecedented 43 months.

Spaceborne Precipitation Radar Ships from Japan to U.S.

Japanese scientists and engineers have completed construction on a new instrument designed to take 3-D measurements of the shapes, sizes and other physical characteristics of both raindrops and snowflakes. The instrument will be shipped from Japan to NASA's Goddard Space Flight Center, Greenbelt, Md., to be integrated into an upcoming NASA Earth science satellite.

'First Light' Taken by NASA's Newest CERES Instrument

The doors are open on NASA's Suomi NPP satellite and the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system.

NASA: Two Waves Formed Japan's Destructive Tsunami

NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized "merging tsunami." The tsunami doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall.

Floods Slowly Recede around Bangkok

By late November 2011, floods were receding around Thailand’s capital city of Bangkok, but only slowly. These images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite compare conditions around the city on November 28, 2011 (top), and November 1, 2011 (bottom).

These images use a combination of visible and infrared light to better distinguish between water and land. Water is navy blue. Vegetation is bright green. Bare ground and urban areas are earth-toned. Clouds are pale blue-green.
