I heard of the idea of having a manned station floating in the atmosphere of Venus, where the pressure is roughly equal to earth sea level.
The idea is exciting, but what I don't understand is how the crew is supposed to come back to Venus orbit, let alone back to earth.
Let us suppose the Venus to Earth vehicle is parked in orbit around Venus (no need to take down then up again all this fuel). The crew only has to get to orbit in a small capsule and rendez vous with it.
Venus is massive like Earth, and the floating station would be nowhere near orbital velocity. So basically, to put a manned capsule akin to the Soyuz back in orbit, they would need the same thing we need to leave Earth: a full blown Soyuz rocket.
How is it planned to descend such a rocket ready to launch at the level of the floating station, and launch it without the facilities of a launch pad, not even the possibility to touch ground (the rocket would melt...)
or is it just a "detail" that have been hand waved so far ?
