ESA astronaut Jean-François Clervoy, using a computer on Space Shuttle Discovery 21 December 1999.
The main objective of this mission was to repair the Hubble space telescope after its gyroscopes had failed. Jean-François was flight engineer. He used the robotic arm to capture and redeploy the telescope, and to manoeuvre his crew mates during their three spacewalks. Jean-François logged 191 hours and 11 minutes in space over 120 Earth orbits.
