By Lisa-Natalie Anjozian , NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 11/27/12) A NASA study using TRMM satellite data revealed that the year 2010 was a particularly bad year for landslides around the world. Around midnight on August 8, 2010, a violent surge of loosened earth roared down mountain slopes and slammed into quietly sleeping neighborhoods in Zhouqu County in Gansu, China. The catastrophic mudslides—the deadliest in decades according to state media—buried some areas under as much as 23 feet (7 meters) of suffocating sludge. 1,765 people died...

By Ellen Gray , NASA Goddard Space Flight Center Original www.nasa.gov Article (published 11/27/12) When it rains it pours, goes the saying, and for the last 15 years, the data on tropical rainfall have poured in. NASA's Tropical Rainfall Measuring Mission (TRMM) was launched on Nov. 27, 1997, and for the last decade and a half has enabled precipitation science that has had far reaching applications across the globe. TRMM Project Scientist Scott Braun looks back at the legacy of the Tropical Rainfall Measuring Mission and a few of the major scientific milestones the satellite has helped...

By Ellen Gray , NASA Goddard Space Flight Center Original www.nasa.gov Article (published 10/17/12) NASA's Global Precipitation Measurement (GPM) Core Observatory satellite went through its first complete comprehensive performance test (CPT), beginning on Oct. 4, 2012 at NASA's Goddard Space Flight Center in Greenbelt, Md. The testing ran twenty-four hours, seven days a week and lasted ten days as the entire spacecraft was put through its paces. "This is the first time we've gotten to see the observatory all put together, running the way it's supposed to be running in flight," said CPT Test...

By Lisa-Natalie Anjozian , NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 4/24/12) If you walk into a cloud at the top of a mountain with a cup to slake your thirst, it might take a while for your cup to fill. The tiny, barely-there droplets are difficult to see, and for scientists they, along with rain and snow, are among the hardest variables to measure in Earth Science, says Ana Barros, professor of engineering at Duke University. As part of the Science Team for NASA's Precipitation Measurement Missions (PMM) that measure rainfall from space, Barros and her...

By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 4/3/12) On March 30, the Japan Aerospace Exploration Agency (JAXA) officially handed off a new satellite instrument to NASA at Goddard Space Flight Center, Greenbelt, Md. The Dual-frequency Precipitation Radar (DPR) was designed and built by JAXA and Japan's National Institute of Information and Communications Technology (NICT). JAXA DPR Project Manager Masahiro Kojima (seated left) formally signed over the DPR to GPM Project Manager Art Azarbarzin (seated right). Behind from left to right: Minoru...

By Aries Keck, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 3/1/12) The Dual-frequency Precipitation Radar (DPR) built by the Japan Aerospace Exploration Agency (JAXA) for the Global Precipitation Measurement (GPM) mission's Core Observatory arrived on Friday, March 16 and was unloaded today at NASA's Goddard Space Flight Center, Greenbelt, Md. Comprised of two radars, the DPR is one of two instruments that will fly on the Core Observatory scheduled for launch in February 2014. Engineers from the Japan Aerospace Exploration Agency (JAXA) and NASA Goddard...

By Rob Gutro, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 3/1/12) 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. The GPM Microwave Imager instrument being placed in the acoustic chamber at NASA's Goddard Space Flight Center on March 1, 2012.
