In the 1960's (I think?) NASA did studies on various emergency situations in preparation for the post-Apollo space stuff that never happened. I remember a zippered inflatable sphere that could be used to EVA a person between vehicles, and I think there was an inflatable cone-shaped reentry device that got out of orbit, and down to a reasonable altitude, before being discarded and the person used a parachute for landing.
