High-Energy Exhaust Shielding for Far-Future Drive Imagine a far-future spacecraft drive that accelerates its reaction mass to a small fraction the speed of light (say, 1,000 km/s). Say the mass flow rate to the drive were 1kg/s, and say the reaction mass were hydrogen. what effect would the resulting exhaust have on humans? On other spacecraft? If f... (more) |

Centripetal Burn in Orbit Imagine a spacecraft in a highly eccentric orbit. Say the craft burns at periapsis towards the planet such that its orbital eccentricity does not change and the craft's periapsis moves with the ship so the two stay at the same point at all times. This would result in a circular orbit, but a faster or... (more) |
