Based at ESA’s technical heart ESTEC, beside the North Sea shore of Noordwijk, the Netherlands, the Mechanical Systems Lab simulates the harsh conditions of space in order to assess the mechanical and thermal performance of key spacecraft elements. 
Performing around 70 tests per year, the Lab fills the gap between individual component and material testing and the full-scale spacecraft testing taking place next door at the ESTEC Test Centre
