Astronaut Kathryn Thornton Works on Hubble Space Telescope

In this image from Dec. 8, 1993, astronaut Kathryn C. Thornton works with equipment during a spacewalk. The spacewalk was part of an 11-day mission, Servicing Mission 1, to service the Hubble Space Telescope. Shortly after Hubble was launched in 1990, NASA discovered a flaw in the observatory’s primary mirror that affected the clarity of […]
