NASA has developed coatings for airbags to be used on the Mars Exploration Rovers because of its lightness

Airbags must be sufficiently able to pad the rocket in the event that it lands on rocks or harsh landscape and permit it to ricochet over Mars' surface at road speeds in the wake of landing. To add to the intricacy, the airbags must be expanded seconds before touchdown and flattened once securely on the ground. 

AIRBAGS 

While most new cars currently accompany airbags, the rocket doesn't. The texture utilized for the new Mars airbags is an engineered material called Vectran that was likewise utilized on Mars Pathfinder. Vectran has double the quality of other manufactured materials, for example, Kevlar, and performs better at cold temperatures. 

Denier is a term that quantifies the distance across of the string utilized in the item. There are six 100-denier layers of the light however intense Vectran ensuring a couple of inward bladders of similar material in 200-denier. Utilizing the 100-denier implies there is progressively real texture in the external layers where it is required, in light of the fact that there are more strings in the weave. 

Every meanderer utilizes four airbags with six projections every, which are completely associated. Association is significant since it lessens a portion of the arrival powers by keeping the sack framework adaptable and receptive to ground pressure. The texture of the airbags isn't connected legitimately to the wanderer; ropes that befuddle the sacks hold the texture to the meanderer. The ropes give the shape of the sack, which makes swelling simpler. While in flight, the sacks are stowed alongside three gas generators that are utilized for expansion.
