The Pisces series is my demonstration of the SDHI-SMS (SumDum Heavy Industries-Service Module System) primarily using stock, KW Rocketry, and SDHI-SMS parts. The SDHI-SMS augments the stock Mk3 Command Pod with a launch escape system, service module, and fairings. I have made a number of variants of the Pisces to fill specific mission parameters but each is designed to be easy to use for newer players.

The Pisces Block D fills the role of a complete Munar mission with both a Pisces CSM and my new Aquarius lander. The CSM itself, like the rest of my Pieces ships, fits 3 kerbonauts while the small lander is just meant for one. The lifter has been upgraded from the smaller SSTO in my other Pisces ships to a much larger two-stage rocket. The powerful first stage handles the ascent and some of the circularization, afterwards its ejected mid-circularization where it can quickly decay. The second stage handles the rest of the circularization and the TMI (Trans Munar Injection) burn with plenty of fuel left-over for almost any type of TMI burn you want or even changing the mission to Minmus. I recommend any type of burn that either gets rid of the second stage either by impacting on the Mun or re-entering Kerbal’s atmosphere for easy cleanup.

The Pisces' SMS engine provides the MOI (Munar Orbital Insertion) burn, any attitude adjustment burns, and lastly the TKI (Trans Kerbal Injection) burn. I recommend that to be on the safe side you disable the cross-feed with the lander so you don’t accidentally use up any of the lander’s fuel supplies. The Aquarius lander has just enough fuel to get one of your brave Kerbonauts to the Mun’s surface, allow them to do a bit of exploration, and return them to a 8-10km orbit around the Mun. There probably won’t be much fuel left in the lander so I recommend handling the actual rendezvous process with the Pisces CSM which should have more then enough fuel.

The lander should be discarded after retrieving its pilot, although there may be enough fuel in the SMS engine to carry it back to Kerbal’s atmosphere. The return burn is easy enough and I recommend a perigee of about 10-20km for a smoother re-entry but the heat shield will be able to withstand almost any type of re-entry.

Built in the VAB in KSP version 1.3.0.
