Hera asteroid mission hears the noise

ESA’s Hera asteroid mission has completed acoustic testing, confirming the spacecraft can withstand the sound of its own lift-off into orbit. Testing took place within the Agency’s Large European Acoustic Facility at the ESTEC Test Centre in the Netherlands. This is Europe’s largest and most powerful sound system, fitted with a quartet of noise horns that can generate more than 154 decibels of extreme noise.
