What’s it like to ride a rocket to Mars?

So, if you spend a billion euros on a space mission, you better be sure it can survive the rocket ride off Earth, reports BBC. 

This video shows a model of Europe’s upcoming Mars rover being shaken to simulate the violent first few minutes of flight on leaving the launch pad. ExoMars, as it is known, is a joint project with Russia to put a mobile laboratory on the surface of the Red Planet in 2021. The hi-tech rover will look for signs of past or present life.  

The vehicle pictured being put through a shake test at Airbus in Toulouse, France, is what is called a Structural Thermal Model, or STM.

It is a near-exact copy of the rover that will eventually be sent to Mars.

Engineers use this STM to run the rule over their design. If there are flaws and something breaks on this test model, the engineers have time to make revisions for the “flight model”.

Peak frequencies in these shake tests reach 100Hz (100 cycles a second). G-forces (accelerations relative to standard Earth gravity) of 10.5 are achieved.
