I have recently started with Kerbal Space Program (roughly a month ago), and I decided to start with career mode. The start of my career, having no experience with KSP, was tough. Many failed launches, a poor Kerbonaut lost(R.I.P. Jeb), and many a fail orbit. Just yesterday I recieved a little bit of science I could scrape off of one last Mun orbit, to get the upgrades I felt necessary for a Mun Landing. The ship went through 2 variations, that ended in utter failure, until I came to this design. It was perfect, and glorious to behold, a modern marvel for Kerbin.

The launch went smoothly, I got into orbit with fuel to spare. I was able to get a trajectory on the Mun, and I propelled myself onward. Once arriving to the Mun I realized that my solar panels had been away from the sun during the warp, I was using a OCT to pilot as I had a scientist onboard, and my SAS was out of power. Crap. I had to turn the ship using my precious RCS reserves to face the sun, catch just as much sunlight as I could, and engage my SAS. It was a success and I was placed in my orbit around the Mun.
As I planned my descent I started to realize that my ship was pulling in one direction. I couldn't figure out why. The descent to the Mun was tricky. Constantly fighting against my tilting ship and limited SAS use.

I finally got it landed to realise that one of the fuel lines feeding into my central tank was not working. The outside tank was full of precious fuel that I needed for my return trip. I quickly scoured the web looking for answers when I found that I could upgrade my facilities to allow fuel transfer. I was saved!
I transferred the fuel into the central tank, planted my flag, and grabbed a soil sample (came with the facility upgrade too =D). I then decoupled my landing gear and shot myself towards Kerbin, running out of fuel in literally the last second of my burn =S
But after a long stressful flight I made it back to Kerbin, I didn't burn up on reentry, and splashed down safely.

This nice mission snagged me a cool 300 Science, the most science I have ever seen =D, and cost me close to 40k. All in all it was an awesome adventure full of hard work and stress, and amazing payoff.
I did not do it because it was easy, but because it was hard.
P.S. oh and I am new here so this was my hello message, I frickin' love this game, and hope to share my love of this game with this community.
Godspeed.
