Core Observatory Passes Centrifuge Stress Testing

The GPM Core Observatory structure successfully completed proof testing in the centrifuge facility at Goddard Space Flight Center. The satellite was tested at several different angles to simulate the increased feeling of gravity’s pull on the satellite during launch. Goddard's centrifuge can accelerate 2.5 tons to speeds so high that the payload experiences forces 30 times greater than the pull of Earth's gravity.
