This is a replica of the interplanetary spaceship used by Scott Manley in his YouTube tutorial
It’s capable to get to any planet and back (without powered descent to Kerbin).
I recommend this calculator to get to other celestial bodies easier: http://ksp.olex.biz/
There are four version:
1. With launcher to get into orbit
12 With launcher to get into orbit and with MechJeb 2
3. Only the ship (You can use this with orbital constructions or cheat it into orbit)
4. Only the ship with MechJeb 2
The mechjeb 2 launcher sometimes does strange things. This is MJ related not because of the craft.
