The NASA Paresev ("Paraglider Research Vehicle") was an experimental NASA glider aircraft based upon the kite-parachute studies by NASA engineer Francis Rogallo.. Between 1961 and 1965 the ability of the Rogallo wing (also called "Parawing") to descend a payload such as the Gemini space capsule safely from high altitude to ground was studied.
Powered parachutes typically use easier-to-manage but less efficient wings, have larger engines, are steered by foot and may be able to take along passengers. There are exceptions; a growing number of powered parachutes use elliptical wings, some use hand controls, and many are light, single-seat aircraft that meet FAA Part 103 requirements.
The company was a subsidiary of the Hispo Company, Limited, which manufactured parachutes for military use and was established in 1982. Hispo also appears to be out of business.
