A recovery system for decelerating/stabilizing and protecting space vehicles, boosters, astronauts, equipment and like payloads, including a paracanopy defined by a frusto-conical flexible uninflated skin forming a decelerator/stabilizer surface having a small inflated torus at it leading end and a larger trailing torus at its trailing end with an inflated annular protective sheath therebetween protecting the payload housed therein, duct means between the toruses and the annular sheath for forming a fluidically rigidified frame, and the fluidically rigidified frame maintaining the flexible skin in taut though uninflated condition during entry and recovery, The paracanopy further can include an inflated buoyant section for recovery at sea, and depending upon the payload to be recovered, the paracanopy can be deployed as a single structure from one end of the payload or from opposite ends of the payload as two separate cooperative structures.
