| 内容記述 | The Primary Mission for Deep Space (DS1) was to demonstrate 12 new technologies one of which was the Ion Propulsion System (IPS). After successfully completing its primary mission, DS1 was given a new mission. The objective of this Extended Mission was to fly by the Comet Borrelly. After the successful Borrelly encounter, the ion thruster on DS1 had to be operated for more than 14,000 hours in space. This provided a unique opportunity to investigate the condition of the thruster after long-term operation in space and determine, to the extent possible, if the thruster wear in space is consistent with that observed in long-duration ground tests. |
