The GPM Core spacecraft has completed hot and cold thermal balance testing in the thermal vacuum chamber at NASA's Goddard Space Flight Center. Next it will undergo hot and cold cycle thermal vacuum testing, where the temperatures are alternatively raised to 104°F (40 degrees C) and lowered to 7°F (-14 degrees C) over the course of the next few weeks.

The GPM Core Observatory has moved from the clean room to the thermal vacuum chamber at NASA's Goddard Space flight Center in Greenbelt, Md. The spacecraft, wrapped in protective blankets, made the short trip by crane across the testing facility where it was then lowered into the 40-foot test chamber.

NASA's 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.

The Mission Operation Review for GPM was held on August 15th and 16th. The agenda included operation reviews of the ground systems, launch and early orbit, instruments, spacecraft decommissioning, and overall mission activities
GPM's two solar array wings completed vibration and acoustic testing at Goddard Space Flight Center, Greenbelt, Md. The solar arrays were integrated to an identical copy of the Lower Bus Structure of the satellite for this testing. These tests and deployments demonstrate the ability of the solar array to withstand the vibrations and sounds the satellite will be subject to during launch as well as test the ability of the solar arrays to unfold once in orbit.
The GPM Microwave Imager (GMI) successfully completed a walkout deployment, spin-up and functional and interface testing after being integrated onto the core spacecraft in May, 2012. These series of tests confirmed electrical and functional performance of the GMI with the GPM Core Observatory.
The High Gain Antenna System onboard the GPM Core Observatory was successfully deployed and functionally tested after being integrated onto the spacecraft late last year. The HGAS is responsible for relaying data collected by the satellite’s instruments to Tracking and Data Relay Satellite System (TDRS) satellites. Data is sent back to Goddard Space Flight Center via a NASA wide-area network.
The 5th International Workshop for GPM Ground Validation (GV) hosted by Environment Canada was held on July 10-12, 2012, in Toronto, Canada.
The electrical integration of the GPM Microwave Imager (GMI) instrument onto the GPM Core Observatory was successfully completed in April 2012. In May, 2012, the Dual-frequency Precipitation Radar (DPR) instrument electrical integration was also successfully completed.
Congratulations to our partner, the Japan Aerospace Exploration Agency (JAXA), for the successful launch yesterday of the Global Change Observation Mission 1st - Water (GCOM-W1). GCOM-W1 carries the Advanced Microwave Scanning Radiometer 2 (AMSR2) which successfully deployed its antenna on orbit.
