Auk and Gull - small upper stages

[Urban_K]

Two small upper stages made to be complete propulsion and service modules for probes, satellites and landers. Can be independently operated = de-orbited.

RCS is only for roll, pitch and yaw = Not made for anything which requires active docking.

(It can easily be seen that the Gull is not as efficient as if it had been built around a X200-8 tank instead. Or if it had used a LV-909.)

Looks mice. I've never seen anyone do something like this by itself
