Fly me to the Mün (a Kerbal Space Program “review”)

I believe that grown ups can be gamers. I do not remember if I have ever written about this topic on this blog, but you might know anyway, that I spend quite some time in front of the PlayStation playing the actual FIFA series in my free time. In this post however, I will talk about something else. I stumbled upon Kerbal Space Program roughly two months ago, and I fell in love with it almost immediately. The game is still in development phase (version 0.21), with updates coming out roughly every two months. Since at this point it lacks carrier mode or missions, you need to figure out yourself what to do, but the main goal is running the space program of the Kerbals, who live on planet Kerbin in the Kerbol System. There are many stock parts available (and an overwhelming amount of community maintained add-ons) to build rockets, landers, rovers, probes, etc. But be careful with your design, because you really need to get your rocket science done correctly (definitely have the cheat sheet nearby, but I think without reading through and following a few tutorials, you will end up crashing your keyboard in madness), since the game is build on a quite realistic physics engine (although aerodynamic drag is not modelled too well so far). You will learn many things about orbital mechanics and actual rocket science while playing (thrust-to-weight ratios, rocket equations, deltaV values, using the navball, orbital manoeuvres, rendezvous and docking, interplanetary travel, aerobraking, and so on). And you are always in control, there is no autopilot. You control the thrusters, the staging, different parts, everything! But instead of going into any further details (which you can anyway look up on-line), let me walk you through my most advanced mission so far. It took at least 3 hours to design, build (using 167 parts), and test, and another 3 hours to fly the mission… (Yeah, long, lonely observing nights… I warn you, do not start playing this if you have only one hour to spare…) I present you Orion-2, a slightly altered Apollo-style mission to the Mün with three Kerbals on board. (Orion-1 was a similar mission, but without a buggy.)

Orion-2 sits on the launch pad, and for clarity I have labelled the different parts. The weather is optimal, there is some wind from the west, but the sky is clear, and lift-off is in ten, nine, eight, seven, six, five, four… [The game is available for PC, Mac, and Linux, and although the graphics are on purpose a bit cartoony, the following screenshots were taken at display settings which are far from maximal, so on a better computer, things look even much nicer - terrain quality is higher, textures are more detailed, shadows and lighting are better, etc.]
