GPM Core Observatory
The DPR was built at JAXA and is being transported to NASA Goddard Space Flight Center for integration onto the GPM Core Observatory.
The Japanese-built radar is a new instrument designed to take 3-D measurements of raindrops and snowflakes.

GPM moves from the clean room to the test chamber on a dolly without wheels. Compressed air is pumped out under airpads that float the Spacecraft on a bed of air. The wind generated when the centrifuge moves at its maximum speed are more than 200 mph - that's tornado speed. But since they move with the centrifuge the satellites tested only feel 20 mph winds. Leaning outward at 45 degrees for one test orientation, GPM comes within 28 inches of the wall. When lifted onto the platform it cleared the ceiling by only five inches.
