On Dec. 15, the Global Precipitation Measurement Core Observatory team completed the post-shipment Comprehensive Performance Test with no significant problems. The testing took seven days to run through each of the spacecraft's systems and subsystems to ensure that the satellite is ready for space.
The testing took place at GPM's launch site at Tanegashima Space Center in Japan, and was the first time all systems had been turned on since GPM's arrival in Japan on Nov. 24.
In mid-January the launch vehicle, a Japanese H-IIA rocket, is scheduled to arrive at Tanegashima. The GPM Core Observatory is scheduled to launch in early 2014.
