Skyfly XI + MoEM IX

This three module Mk.2 system allows you to land three Kerbonauts on Moho, and maybe even bring them back.

'Skyfly XI' cargo SSTO can lift ~ 28 tons payload inside Mk2 bays to Kerbin orbit.
'Nuclear Interim Propulsion Stage' NIPS J can transfer a 12 ton lander from Kerbin to anywhere in the Kerbol system.
'Moho Excursion Module IX' MoEM is a compact lander with built in ISRU that works on most bodies except Eve, Tylo and Laythe.
This is a lighter and more environment friendly alternative to the expendable Skyfly X.

This model uses a good amount of part clipping. All parts are visible in some capacity though.

- Skyflys XI center of lift is tuned for easy ascend to orbit. Reentry will be messy. Try going in tail first, extend air brakes.
- Open Skyfly payload doors before deploying parachutes.
- Thrust to weight ratio of the NIPS + MoEM stack is low. Use periapsis kicks to reduce the time needed for the interplanetary transfer burn.
- MoEM IX is only tanked with 403/678 OX but full LF to maximize the range of NIPS
