SMOS Payload Module on the Vibration Table at ESA-ESTEC

In June 2005 the Structural Thermal Model (STM) of the SMOS Payload Module underwent vibration tests, which simulated the vibrations it will experience during launch. Subsequently, it was subjected to a high-level acoustic noise tests, which simulated the acoustic environment of the launcher. The test campaign concluded with a Thermal Balance test in the Large Space Simulator to ensure the payload will withstand the temperatures it will be exposed to when in orbit.
