I signed up just to express my humble gratitude to @ShotgunNinja. The mod is awesome!
I played a excrements out of KSP last year. Week ago I decided to blow out the dust and try it once again. I remember how easy was it to reach the Minmus and land a crew on it. I thought it would still be a piece of cake with kerbalism. Man, how wrong I was!
The first mission sent to Minmus failed because kerbonauts froze to death. Yeah, baby! I was in a beginning of the hard career mode, before any solar panels were invented. So my mistake was in a miss-calculation for the amount of required batteries.
The second Minmus mission burned in the atmosphere of Kerbin, because there were none to pilot the ship – the crew died from the starvation long time before – during the flight to Minumus.
The third ship to Minmus had solar panels and plenty of food. Alas, oxygen scrubber at 50% was not enough to provide fresh air for the entirety of the flight. The crew died in agony during the return flight.
The fourth mission has been promising glory and fame to its crew. There was plenty of batteries, working solar panels, separate cash of food and few extra oxygen tanks. I even reinforced crew cabins with some radiation protection. This time, my glorious kerbonauts reached Minmus safe and sound. They even landed and placed some flags for themselves and their fallen comrades! But when everybody finished gathering that scarce scientific data, it became clear that there are not enough fuel to return Kerbin atmosphere. They could take off the Minmus and reach the high orbit of Kerbin. But that was all. So, heroic kerbonauts gave their lives on the orbit of Kerbin in a dare attempt to jump off the ship and reach the Kerbin using EVA. Their suits didn't have much battery charge, so they froze to death before the oxygen run out.
The fifth mission concluded the Minmus program by rescuing science data from the dead ship on the orbit. That dead ship was later renamed to "1st interplanetary monument". It will always remind other crews about the importance of sacrifice for the better good (and some science).

Thanks again for the great stuff! It adds some much challenge to the base game.
A lot of people claim that kerbalism doesn't work with RT2. I run them both simultaneously, I just have to place 2 sets of antennas. I didn't build any major relays yet, I'm not the expert, but everything seems to work as expected so far.
