In 1990 a joint ESA/NASA mission launched the Hubble Space Telescope, the most powerful astronomical tool ever built.This short film covers the scheduled Endeavour space shuttle project (December 1993) to link with the telescope in orbit. Several spacewalks are planned with the purpose of servicing key components, including replacing one of the solar arrays used to power the telescope. Servicing requirements and design solutions are outlined.
