During the second servicing mission to Hubble Space Telescope, astronaut Steve Smith (on the robotic arm) guides the Space Telescope Imaging Spectrograph (STIS) into position while Mark Lee assists. The installation took place during STS-82, the 22nd flight of the Space Shuttle Discovery, in February 1997.
Engineers at Ball Aerospace in Boulder, Colorado, examine STIS prior to its flight aboard STS-82, the second servicing mission to Hubble Space Telescope.
