spacelemming

First played the 0.13 demo after Sips made a video of it. Managed to get into a few highly eccentric orbits but soon stopped as my laptop couldn't really run the game. Came back later after I built a pc, also having discovered Scott Manley at some point, and decided that if I could successfully land on the Mun and return in the demo, I would buy the full game. This was towards the end of 0.17

I've found that I now try to squeeze as much as possible out of my missions. Previously I'd built a ship for one purpose, carry out it's mission, and send it home. However, now I try to see what else I can do to get more science. For example, I sent a small rocket (covered in science equipment) into low Kerbin orbit, intending for it to just orbit a few times and gather some data. However, having been in LKO several time, my science levels were depressingly low... so I went for a Mun flyby and then landed on Minmus (I reeeaally overestimate the amount of fuel I'm going to need!).

Landing I can do fine, it's one of the easy things for me. Landing within a km of a target, however, now that's difficult. Other than that, building good SSTO spaceplanes. I have designed two that can actually get into orbit, however the second one ran out of rocket fuel and had to resort to it's RCS.

In one of my early Mun missions I had enough fuel to escape from the Mun, but not enough to lower my periapsis into the Kerbin atmosphere (I didn't know the best places to burn at that point). I didn't have any RCS and so had to get my Kerbal out and push the capsule. With the eventual help of another Munar flyby I was able to get him home safely.

I open up Whack-a-Kerbal and see how survivable my planes are!

If you love science then for the love of God don't read the Youtube comments, they gave me cancer!

I've had a similar problem. In my case, when I docked a Munar lander and the tug I used to take to Mun and back with my Kerbin station, I could no longer separate the lander from the tug. It seems that, since the two were docked together when they reached the station, it treated them as one ship. To solve the problem I had to undock from the station, then undock the lander from the tug, and then redock the lander with the station (on its own) before I could use the tug separately again.
