A deafening roar accompanies the launch of a rocket. The vibrations that result can potentially damage or even break the instruments on board, and so experiments must be carried out to assess the impact of these vibrations on the spacecraft. These experiments are known as “vibration tests”. The picture shows ASTRO-H placed in the vibration test room. Accelerations sensors are connected, and preparations are being made for the test. Once the tests have been completed, we can be sure that ASTRO-H will safely withstand the great noise of the launch.
