Image: Magnetospheric Multiscale Observatories undergo spin tests
The Magnetospheric Multiscale, or MMS, Observatory #4, is undergoing spin testing on the Miller Table for Mass Properties at NASA's Goddard Space Flight Center in Greenbelt, Md.
Engineers use this machine to determine the spacecraft's center of gravity, adding counter balances as needed to ensure it spins correctly in orbit. All four of the MMS observatories undergo this testing prior to launch.
