Success for Mars rover bag test BBC

The project to design and build a European rover to send to Mars has passed an important milestone.
Engineers have demonstrated a vented, or dead-beat, airbag technology that could be used to cushion the vehicle’s landing on the Red Planet.
An effective entry, descent and landing system will be critical to the success of the ExoMars mission, as it is known.
The test’s success will be welcome news to European space delegations as they meet on Monday to review the project.
