چکیده انگلیسی
We describe a concept for spacecraft propulsion by means of an energetic ion beam, with the ion source fixed at the spacecraft starting point (e.g., a lunar-based ion beam generator) and not onboard the vessel. This approach avoids the substantial mass penalty associated with the onboard ion source and power supply hardware, and vastly more energetic ion beam systems can be entertained. We estimate the ion beam parameters required for various scenarios and consider some of the constraints limiting the concept. We find that the “ion beam sail” approach can be viable and attractive for journey distances not too great, for example, within the Earth–Moon system, and could potentially provide support for journeys to the inner planets.
