  3. Milestone

    Deep Space 1 lost its star tracker

    Subsequent camera-assisted operation did not immediately restore the missing native attitude history.

  4. Flyby

    Flyby of comet 19P/Borrelly

    19P/Borrelly

  5. Mission end

    Deep Space 1 ended its mission with ion-engine shutdown

    The source reports about 20:00 UTC, with the radio receiver left on. This is not an exact final tracking or last-signal epoch.
