The space station wants to have a perfect microgravity environment, right ?
However, air resistance is constantly applying a negative acceleration on the station, and this requires periodic reboots which give a huge "jolt" compared to the desired pure acceleration/vibration free environment. Could today's ION drives provide a constant force that would be in the same ballpark as the force of air resistance ? If they had an ION drive working all the time that provided the exact same force air resistance, then not only would they no longer need reboosts, but wouldn't that also provide a better micro-gravity environment for research since deceleration due to air resistance would be eliminated ? |
