| 21. | On 4 November 2009, the ion engine D automatically stopped working due to an anomaly from degradation.
|
| 22. | Cautious ground controllers will wait a week or two before firing up Deep Space 1's ion engine.
|
| 23. | Deep Space 1's ion engine will run on 180 pounds ( 82 kilograms ) of xenon gas.
|
| 24. | :: The same might happen to ion engines and anything that follows ( for quite some time ).
|
| 25. | In the much slower real world, solar-powered ion engines are 10 times more efficient than traditional chemical engines.
|
| 26. | Or, this might be a good application for ion engines, which are more efficient, but have very low thrust.
|
| 27. | One mission proposed using the electricity to power ion engines, calling this method radioisotope electric propulsion ( REP ).
|
| 28. | On 28 August, " Hayabusa " was switched over from the ion engines to the bi-propellant thrusters for orbital maneuvering.
|
| 29. | Rayman says that, over time, ion engines can deliver 10 times more thrust per pound of fuel than chemical rockets.
|
| 30. | To avoid a lapse in propulsion, the mission team hastily exchanged the active ion engine and electrical controller with another.
