S73-26401 (23 May 1973) --- An umbrella-like mechanical device called the "parasol", one of the several sunscreen possibilities being considered for use in shading the overheated Skylab 1 Orbital Workshop (OWS), receives a checkout in the Technical Services shop in Bldg. 10 at Johnson Space Center. Here, a technician starts to deploy the "parasol" sunshade. The "parasol" is designed to fit into the T027 experiment photometer canister. The canopy portion of the "parasol" measures 24 feet by 22 feet. Photo credit: NASA
