It's always hilarious to watch the timer in minimal mass missions. Imagine the meeting at KSC "Hey who wants to spend 2 1/2 years floating around in a space suit because we're too cheap to make a decent rocket so that you can have a normal Minmus mission that should take less than 20 days?"

From what I remember, kerbals can actually survive re-entry if done right, so technically you wouldn’t need the radiator

[@anonymouskerman8318]

yes they can, i did it in my first video on this channel, though i had RCS available. it might not work without

[@BradleyWhistance]

Its certainly possible with the use of eva fuel. If you are aware of a reliable way to re-enter kerbals without using eva fuel, let me know =)

[@ultimatesteve9647]

@@BradleyWhistance You might not want to use this, as it is technically a glitch, but if you leave the Kerbal on an elliptical orbit with a periapsis just above the ocean, go to the tracking station, time warp until the Kerbal is at periapsis (the game won't delete the Kerbal because he/she is still in orbit I think) and then load him/her. Should slow down super fast, before the heating kicks in enough to be deadly.

[@yaktyafiyae]

Yes I can do it from a 70 km orbit, I use all the eva fuel to slow at 69 km and when I'm out I drop, and it barely avoids the kerbal overheating

Could probably improve the mission using flags in some way, since they can work to lithobrake really well and can also protect a kerbal from heating.

[@michaelgoetze8531]

Hi Brad, I have a suggestion for you which is more of a piloting challenge than a build challenge. My proposal is "single burn to Minmus". Starting on the surface of Kerbin, launch directly to an intercept of Minmus, so the rules are: (1) no lighting additional engines after leaving the surface of Kerbin, (2) no throttling down below 33%, (3) when you shutdown your engines after launch you must be on course to reach the sphere of influence of Minmus. Bonus points if you can pull this off from the Woomerang Launch Site.

[@elopeous3285]

A little orthopedic correction by the minmus surface

[@hallucinogender]

I wonder if it's possible to change up the mission profile by having a kerbal remove parts from the vehicle mid-flight. I don't know enough about planning the kind of mission that relies heavily on the quirks of stock KSP to function for me to be able to make any reasonable estimates on how this may work, but it does seem to be an option that might be possible to consider now.

[@ultimatesteve9647]

Would it be possible to bring up a second (or more) EVA fuel tanks, maybe in a container, or if possible not attached, just sitting in the fairing? Then go EVA-only from LKO all the way to Minmus and back,? This might end up making the craft heavier, though.

[@Shaun_Jones]

At that point, you might as well just take up a capsule. Getting in a command pod instantly refills EVA fuel.

maybe start the flight at a bit of an angle so that the mun assist will boost your angle even more and get you into the same orbital inclination as minmus without any delta v expenditure?

[@chickennugget5557]

YES!

[@maximk.617]

Yaaas You're back!!!

[@davynolan182]

Using the topography of of minmus you might be able to shave a little delta V.

[@eekee6034]

I'm wondering how light rotors are. I'm thinking of a solar-powered rotorcraft to get out of thick atmosphere, and ion thrust the rest of the way. The kerbal would have no inventory or perhaps a parachute; that would be part of the saving, so it might be best to count the kerbal and inventory as part of these things. I might try this but don't have the patience to do it well. I'd be happy if someone better than me did it.

[@shbibe7143]

LETS GO im happy now

[@nonsaline]

Idea: have an air intake offset by like 75km so you can get to lko on air breathing engines 🤷‍♀️

[@UnlimitedRun]

IIRC KSP doesn't apply atmospheric drag to a craft that has a center-of-mass above the atmosphere, even if some parts dangle down into said atmosphere. So I don't think your idea works.
