NASA technicians spun the Global Precipitation Measurement (GPM) satellite up to just over 10 RPM in Goddard Space Flight Center’s High-Capacity Centrifuge facility March 31. At that speed, the spin exerted a lateral pressure of 2.4 G’s, or 2.4 times the force of gravity on the satellite.

Spin tests such as these are used to determine whether the forces of launch could adversely affect hardware we put into space, and to test spacecraft chassis design.
