    I don't think "admitted" is the right word. It's not like it was a secret .....snip....... The transfer of flights from the S-1B to S-1C stage would also help reduce the unit cost of the S-1C. I think the ETS style Saturn 1C only makes sense in a world where NASA is committed to abandoning the Moon and Saturn V, and of course IRL we got the Shuttle as a result.

    Yeah, it was a good enough type program with schedule and cost constraints.  It's a pretty clever design, they made something pretty capable with some tooling they already had.  That is good design, they understood not only what to design, but what they could also build.

    To the point, all of the Saturn hardware had some room for both reliability and part count improvements.  They had not actually optimized them fully.

    It's so hard to guess what would have happened.  There were numerous options, and a few that seemed to stand out. The INT-20/21 seemed promising.  AAP briefed Congress on updated stretches to S-1b as well.  So if they kept flying it, they might have improved the engines and added more fuel or added titian iii srbs. The big item is that Saturn 1b is probably good enough, I mean the Russians flew/fly Proton as their heavy lift for a long time and it's comparable in performance.

    Then if you look at the cost numbers that were quoted to Congress in '67, if you manage to make a couple of INT-20s common enough with ~4 Saturn 5 rockets built in a year, it pushes the unit cost down considerably.  6 Saturn V in a year was sort of a knee in the curve.

    Or you can cut it all and focus on the future with a flexible space shuttle after massive budget cuts and loss of interest.

    Fix

    Just a general question, is there any consensus on what would have been the replacement/upgrade for the Saturn 1 if we kept flying?

    Probably another upgrade for the H1? H2 was going to be basically a new engine?  Does the E1 fit as an upgrade (I know the timelines were not right on that engine, but gameplay wise it is an upgrade right)?

    Then probably SRB on the side for heavy lift?

    What do the people think?

    The stock game now has a delta V readout although Kerbal Engineer is nicer and will give you more information. You can tune the solid fuel quantities to suit your requirements and see the delta V readout in the VAB. For the sake of convenience, upper stage solids have a cut off feature, look for "Features BDB Safe Solid (tm)" in the part description. Since its not so practical in game to tune the delta V requirements as precisely as real life we give you this option to shut down (but not restart). This can be done using the right click part action window or via an action group. Finally I would recommend a liquid final stage or on board propulsion on the payload for final orbit adjustment as even with safe solid it probably wont be that precise. Hope this helps :) 

    A common thing I do is use an bossart-inon to put a satellite into geo-transfer-orbit.  Then I use the solid to move the Pe all the way out when the orbital requirements are meet.  Then the spacecraft has a little attitude control system that can fix the orbit errors and kerbal-station-keep.

    You might want to play with the mass of the payload or add ballast.  It's not possible to fly every rocket to a circular orbit for every alt.

    E.g. may need like 120*250/350 if you are too light in jnsq.

    Pvg also allows you to set the pitch program rate, which will help you get higher before stable guidance is reached.

    Control systems are hard....

    Then I would suggest doing as suggested,   ....

    Most Heat-shields are actually not ablative... Sure they may be one use but rarely do they loose more than 20% of their mass (off the top of my head.)   Yet nearly every heat-shield in game looses at-least half of it's mass when being used it seams.....

    Yeah I agree. TPS are complicated layers of all kinds of stuff.  They don't melt away in the scale of ksp.

    It's more like the kerbal TPS is a model, and you are using it by bringing more or less ablator.  They just set the max to a big number to make them enough to work at whatever use in kerbal.  IMHO, is not a realistic enough simulation to care that much.

    It's your gaming experience, so go for whatever is the most fun to you.  You might need to use the up-rated engines for more margins for now.

    Happy flying!
