Entire spacecraft are checked inside the ESTEC Test Centre. A test model of the Entry, Descent and Landing Demonstrator Module of ESA’s 2016 ExoMars mission subjected to a series of intense shaker tests to simulate a rocket launch. ESTEC’s Test Centre is the largest centre of its kind in Europe; one of the largest in the world. A set of state-of-the-art test facilities are located under a single roof, all within ‘cleanroom’ conditions comparable to a hospital operating theatre to protect delicate spacecraft subsystems.
