And escape velocity. I believe I'm right in saying that we don't have any proven technology that could leave Jupiter after having 'landed'.

- ClumsyPilot 5y agoThere are fozens of moons avaliable for gravity assists and refuels, those are definitely reachable and leave-able, although i dont have a totally clear image of where they are in the gravity well
- KineticLensman 5y agoGravity assists primarily work when you are inbound at speed to the body you'll slingshot around, not struggling to reach it's altitude from beneath (i.e. you are lower in Jupiter's gravity well than the moon, because you are launching into space from a stationary start).
- ncmncm 5y agoEscape velocity can be achieved after refueling from a depot in low orbit, if you can get there. That's just operations, not fundamental physics. I wonder why people talking about skyhooks never talk about ring-shaped ones. It seems like the timing demands on users would be radically looser. I think the structural stress problems would be a lot easier, too, maybe enough to make up for the 22/7 size ratio.
