I have a question for the community, during the late 1960's and early 1970's NASA built a moon rocket. it composed of a Command and Service Module, a Lunar module, and a transfer stage. Why were the command modules never reused, it would have saved money and time. and if I misspelled anything please forgive it its just spelling. alpha tech
MechJeb version 2.5.8 (the only mod I have) KSP Version 1.1.3 (Have not upgraded so I can use MechJeb.) W 8.1, GTX 1080, 16 GB Memory (Still plenty of crashing with a large rocket. Go figure.) Anyway, the moment I hook up MechJeb I get a build warning (orange triangle), "Command module faces the wrong way." Of course the warning goes away the moment I disconnect MechJeb. It matters not where I place MechJeb either.
I am optimising a spaceplane that I successfully got to orbit, docked and de-orbited. It flies really nicely, has great manoeuvrability, can land really gently but could do with a bit of work getting it to dock nicely. It has 2 Mk1 Inline Cockpits, and I think that I want to change it for a Mk1 Crew Cabin. I am going to use it for crew rotations - no cargo. Detailed analysis if you really want it: The advantages that I see are that it does not require a pilot to be one of the crew that is rotating, as well as being marginally lighter and cheaper (20Kerbucks saved - woo) and the other specs are about the same. I could also use it for tourists too. Having a cargo bay has the small advantage that I can put other radially attached parts in there too to avoid drag (mechjeb is the main one). The big disadvantage is that if I loose power then I am completely dead in the water space, whereas if I had a command module I could at least manoeuvre using RCS or control surfaces, or fire the engine when I am pointing in approximately in the right direction. Another small disadvantage is that there are 3 things in the plane instead of 2, this makes it slightly longer and has more places for it going spaghetti on me (it does have enough lift to tear itself apart at mach3 under 10km altitude). I guess that I have a few more options in placing components wrt getting the CoM in the right place, but equally more complexity. Any more advantages or disadvantages that I have missed?
