Airbags are fully inflated in this photograph taken at the JPL In-Situ Instrument Laboratory or 'Testbed,' where engineers simulated the orientation of the airbags during the deflation process.

The airbags are fully inflated in this photograph taken at the JPL In-Situ Instrument Laboratory or "Testbed," where engineers simulated the orientation of the airbags during the deflation process. The airbags had to be inflated seconds before landing on Mars' surface and deflated once safely on the ground.
