SUMMARY: NASA researchers finally shut down an ion engine that had been running continuously for 30,352 hours. The engine was a duplicate of the one that flew on Deep Space 1, NASA's mission to test out a range of experimental technologies, and was originally designed to work for 8,000 hours. The engine was finally turned off so that engineers could take it apart to examine the different engine components for wear. Deep Space 1's engine operated for 16,265 hours.
