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

GPM Begins Final Comprehensive Performance Test

The test will run 24/7 over the next few weeks as every system and subsystem is turned on and run through its tasks. This is the first time all the Core Observatory systems have been powered on since its shipment to Japan. The results of the tests will be compared to pre-shipment performance test

GPM Undergoes Post-Shipment Inspections

Following arrival in a cleanroom at the Tanegashima Space Center in Japan, the Global Precipitation Measurement (GPM) core observatory was attached to a custom-designed satellite mount which allowed the NASA team on-site to perform preliminary inspections and evaluations of the spacecraft.

NASA's GPM Satellite Begins Journey
For the past three years, the Global Precipitation Measurement (GPM) Core Observatory has gone from components and assembly drawings to a fully functioning satellite at NASA's Goddard Space Flight Center in Greenbelt, Md. The satellite has now arrived in Japan, where it will lift off in early 2014. The journey to the launch pad has been a long and painstaking process. It began with the most basic assembly of the satellite's frame and electrical system, continued through the integration of its two science instruments, and has now culminated in the completion of a dizzying array of environmental...
