No, the absolute minimum speed IS required. Anything below that and you’re just making your orbit elliptical.

- pedrocr 7mo agoThat seems wrong. If you have a way to maintain enough propulsion for long enough you can escape the gravity well at any arbitrarily low speed. You "just" need to maintain that speed long enough for the escape velocity from the gravity well to go below it as it diminishes with distance from the mass.
- Rover222 7mo agoOh yeah, 1.01 Gs of endless propulsion will work. I was just arguing in the context of existing technology.
