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. 

This animation shows the launch and deployment of the GPM Core Observatory. GPM is scheduled to launch in 2014 on an H-IIA rocket in Japan.
