The OSIRIS-REx spacecraft has completed the Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) system level test. This test has three objectives. The first objective is to test for Radiated Emissions, which are the release of electromagnetic energy from the spacecraft. To pass this test, the team had to verify that the emissions from the Spacecraft do not violate the limit specified for both the Launch Vehicle and the Spacecraft.
