Introducing Kerbal Space Program!
KSP is a game where the player creates and manages his own space program.
Build spacecraft, fly them, and try to help the Kerbals to fulfill their ultimate mission of conquering space.
The game is currently under heavy development. This means the game will be improved on a regular basis, so be sure to check back for new updates.
Right now, KSP is in Alpha state, but we want you to try it out and have fun with it. The first versions are free to download and play, and will remain so forever.
My record is 2840 k altitude (same rocket) with a total mission time of 2 hours and 7minutes !
What are you waiting for? GIT IT NAO. There are mods, don't use them. At least until you've exhausted the standard parts and reached 'space', most mods are just improved rockets with no weight to push ratio and stupendous amounts of fuel.
