Spacecraft Magnetic Test Facility
The Spacecraft Magnetic Test Facility is housed at NASA’s Goddard Space Flight Center. It was built in 1966 to allow the evaluation of magnetic movement in crewed and uncrewed spacecraft, and for the precision calibration of magnetometers used in spaceflight. Before their successful launches and deployments, a number of communications, weather and Earth resources satellites were tested in the facility. The building itself is constructed of non-magnetic materials and contains a magnetic coil system six feet (1.8 meters) in diameter that allows the cancellation of the Earth’s magnetic field.
