STS103-501-026 (19 - 27 December 1999) --- Astronauts C. Michael Foale, left, and Claude Nicollier (on Discovery's robotic arm) install a Fine Guidance Sensor (FGS) into a protective enclosure in the Shuttles payload bay. Foale and Nicollier performed the second of three space walks to service the Hubble Space Telescope (HST) on the STS-103 mission. A large format camera inside Discovery's cabin was used to record this high-resolution image, while the Shuttle was orbiting above ocean and clouds.
