Engineers have faced a very difficult challenge, and that is how to make Mars rover twelve thousand miles per hour off the aircraft from entering air pillow bags  the atmosphere is reduced to twelve miles landed on the Martian ground.

And a parachute, used to cushioning air bags mounted in the Pathfinder is also used in the Mars rover. Twenty four white grape bunch inflated inflatable warehouse surrounded landers, rovers tightly wrapped in the inside. The air bag is a durable synthetic material called "Vectran". 

Manned spacecraft,  Air Bag aerospace pilots wear space suits are made ​​with this material. Similarly, with respect to the 1997 action increase in weight, air bags do a re-design. Repeatedly the increase of the weight of the dropping test proved causing severe wear and tear.

 After that, engineers and design the air bags air bag manufacturers

  double air positions in order to reduce the risk of damage when landing, because the lander landing speed is very high, and very likely landing on rocks and other dangerous areas.
