Europe’s largest test centre
The ESTEC Test Centre is the largest centre of its kind in Europe and one of the largest in the world. Its cleanroom complex stands on the dunes of the Dutch coast and is built so that hardware can move between test facilities without being reconfigured.
Shaking
Shaker tables expose satellites to the severe vibration of launch to check that nothing is damaged. ESA describes its hydraulic shaker as the most powerful in Europe.
Noise
A launcher is extremely loud. In acoustic testing the satellite is exposed to that noise using what ESA calls the loudest sound system in Europe.
Vacuum and cold
In the space simulation facility, satellites spend weeks in vacuum and at extreme temperatures to show that they will keep working for their planned lifetime. ESA’s chamber is the largest vacuum chamber in Europe, with a Sun simulator and liquid nitrogen circulating through its walls.
The missions tested here then fly in the conditions described on our sister site Pasadena.science.
