DPR arriving on a truck at NASA Goddard
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...
Scientists stand around the GMI which just arrived at 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.

GPM on the High Capacity Centrifuge
In the clean room at NASA Goddard Space Flight Center in Greenbelt Md., the Global Precipitation Measurement (GPM) mission's Core satellite is steadily taking shape. Set to measure rainfall worldwide after launch in 2014, GPM's two solar panels are the latest components currently undergoing rigorous testing before being integrated with the spacecraft, a process that began seven months ago when the main structural elements went on an unusual ride. GPM moves from the clean room to the test chamber on a dolly without wheels. Compressed air is pumped out under airpads that float the Spacecraft on...
