Entry to the atmosphere is an unavoidable passage when returning from outer space or landing explorers on atmospheric planets such as Mars. The most difficult hurdle to entry is aerodynamic heating. To overcome this, a "deployable-type, flexible-membrane-structure aeroshell" was proposed, where an air-brake like umbrella unfolds to slow down the vehicle, and its effectiveness confirmed by computer simulation, wind-tunnel, balloon, and sounding-rocket experiments.
