Shortly after the Hubble Space Telescope was deployed in 1990, the observatory's primary mirror was discovered to have an aberration that affected the clarity of the telescope's early images. Fortunately, Hubble, orbiting 353 miles (569 km) above the surface of the Earth, was the first telescope designed to be visited in space by astronauts to perform repairs, replace parts, and update its technology with new instruments. Servicing Mission 1, launched in December 1993, was the first opportunity to conduct planned maintenance on the telescope. In addition, new instruments were installed and the optics of the flaw in Hubble's primary mirror was corrected.
Highlights from upconverted 16mm film B-roll of Servicing Mission 1 (SM1). Includes crew training, EVA highlights, HST deployment, MOCR activities and COR activities, Corrective Optics Space Telescope Axial Replacement (COSTAR) installation to counter effects of the flawed shape of the mirror, solar array jettison and more.
Astronauts: Richard Covey, Kenneth Bowersox, Kathryn Thornton, Claude Nicollier, Jeffrey Hoffman, Story Musgrave, Thomas Akers
Spacewalk #4, Thomas Akers and Kathryn Thornton installed COSTAR and added a co-processor to the telescope's computer. Pilot Kenneth Bowersox performed two orbital maneuvers to boost the telescope's orbit.
