I got back into KSP a few weeks ago after not having played in like a year or more. Last time I was playing this, landing on the Mun required dead-reckoning and lots of trial and error planning (no maneuver node system, no quick save, no multiple craft) and the sun was just a bitmap in the sky. I had figured out a direct to mun lander craft using a few modded parts and was able to consistently land and return... and then got bored.
But the current state of the game is awesome! I'm totally fired up again to be playing... I build my own fleet of Voyager style probes with an ion engine to place in orbit around all the planets. The only problem is that the ion engine requires so much electricity draw I can't sustain full thrust which makes braking for orbit take like 2 hours even on 4x time acceleration.
It would have been way more efficient to just use chemical rockets... my launch vehicle for the probes can easily lift enough.
Either way, since starting over playing the game again, I created a pair of Sputnik style low-Kerbin orbit satellites, then a few manned orbit missions, followed by a satellite around both moons, and a pair of manned Munar orbit missions. Then sent unmanned missions to Duna, Jool, and Eeloo. I had one on the way to Dres, but since it was my first time ever using the ion drive (and since I didn't bother to test my spacecraft in a Kerbin parking orbit first :derp: ) I found out too late that it takes like 60 times more solar power than I realized to operate that motor and I couldn't brake for orbit... so it's in a big ole solar orbit that may or may not eventually impact Dres.
Finally, I built myself a "rescue tug" type craft that has tons of docking options, including the ability to chain a bunch of fuel tanks to the back of it so I can lift fuel on separate flights, then tow them out to stranded craft elsewhere. The only problem is that a) ships with CoT above the CoM seem to fly like **** in KSP for some reason and b) even the big docking port tears apart ridiculously easy.
So, it was a lot of effort building this heavy-lift vehicle to get the tug and a large tank of fuel into orbit, only to take like 45 minutes to dock (I always seem to have to dock when I'm on the dark side of the planet, and I never have enough lights), and then the damn thing tears apart and explodes any time I try to fly anywhere.
Either way, it's fun to be playing again. I would kill to be able to build and launch a space elevator... so I can easily lift fuel and gear to a geo-sync space station for staging larger projects to elsewhere... but I guess geo-sync orbit in KSP intersects with Mun's sphere of influence or something which would fling apart anything parked up there.
