Effective extravehicular-activity (EVA) operations depend upon having the proper tools from simple wrenches to smart powered socket drives to powered adjustable foot restraints. The Space Shuttle carries a standard toolkit in the cargo bay for emergencies. Many special tools have been developed for the recent satellite repair missions; i.e., Solar Max, Westar/Palapa, and Leasat. Many more are being developed to maintain the Hubble Space Telescope on orbit for 15 years. The EVA tools developed and used in space to date are summarized and some of the new tools now in development are described herein. Finally, the requirements are given for several additional tools which may be needed in the future.
