03.21.13 - The NASA Precipitation Measurement Missions (PMM) Science Team for the TRMM and GPM missions met on March 18-21, 2013 in Annapolis, MD.
03.15.13 - Following the completion of thermal vacuum testing in January 2013, the Core Observatory team started the Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test phase.
01.31.13 - The GPM Core Observatory completed thermal vacuum testing at NASA's Goddard Space Flight Center in Greenbelt, Md. on Jan. 16, 2013. After twelve days to carefully remove the testing equipment, stow the High Gain Antenna and GPM Microwave Imager, and lift the spacecraft out of the thermal vacuum test chamber, the spacecraft was moved back to the clean room on Jan. 28.
12.17.12 - 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 40 degrees C and lowered to -14 degrees C over the course of the next few weeks.
8.16.12 - 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.
8.10.12 - 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.
7.27.12 - 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.
7.24.12 - 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.
7.10.12 - The 5th International Workshop for GPM Ground Validation (GV) hosted by Environment Canada was held on July 10-12, 2012, in Toronto, Canada.
