Hello, all - A question has come back to tickle my brain. Could a vehicle with less than 1G of thrust manage to escape the Earth's gravity well? I'm thinking something like Space X's Falcon 9. As it landed, with just a little more thrust, it could go back up again, I would guess. So, if it could apply that tiny bit more thrust - and, assuming an infinite fuel supply - could the Falcon eventually leave Earth's gravity well? I'm guessing that the thrust involved would be less than 1G since the delta v is certainly less than 9.8m/s; say, a few inches per minute. I mean, it's going up - at that few inches per minute - and, after enough time has passed, I'm guessing it could, eventually, reach a point where the Earth's gravity is negligible and will have escaped Earth's gravity well. But, it will never have reached escape velocity. This seems wrong to me, but my head isn't wrapping around it properly. Where have I got it wrong?
