That is the task of a 3000 sq. m cleanroom complex nestled in sandy dunes along the Dutch coast, filled with test equipment to simulate all aspects of spaceflight: the ESTEC Test Centre.
Its major infrastructure includes Europe’s biggest vacuum chamber, equipped with a Sun simulator with liquid nitrogen run through its walls to reproduce space conditions; Europe’s loudest sound system, used to blast satellites with simulated launch noise and Europe’s most powerful hydraulic shaker table, reproducing launcher vibrations equivalent to a major earthquake.
