NASA’s InSight Mars lander has “skirted” the issue of fully deploying the wind and thermal shield (WTS) over the French-built seismometer.
Photos taken by the lander’s Instrument Context Camera (ICC) show the gold-coated thermal skirt. The WTS was developed by NASA’s Jet Propulsion Laboratory.
The WTS consists of an aerodynamically shaped aluminium cover with a honeycomb structure to which is attached a gold-coated thermal skirt.
The extendable skirt is bordered around its circumference by a kind of chain-mail, not unlike that worn as armor by mediaeval knights.
Its weight alone allows the skirt to descend. Its platelet structure cover obstacles such as pebbles, sealing off the WTS.
