Description

In Kerbal Space Program, take charge of the space program for the alien race known as the Kerbals. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics. Launch your Kerbal crew into orbit and beyond (while keeping them alive) to explore moons and planets in the Kerbol solar system, constructing bases and space stations to expand the reach of your expedition.

Kerbal Space Program features three gameplay modes. In Science Mode, perform space experiments to unlock new technology and advance the knowledge of Kerbalkind. In Career Mode, oversee every aspect of the space program, including construction, strategy, funding, upgrades, and more. In Sandbox, you are free to build any spacecraft you can think of, with all parts and technology in the game.

Key Features


  • Build spaceships, rockets, and vehicles using any imaginable combination of parts, each with their own function that will affect the way your spacecraft behaves.
  • Take full control over your ship’s setup to execute complex flight maneuvers.
  • Manage your Kerbal crewmembers, including hiring, training, and sending them into space to become heroes.
  • Discover a whole star system with unique moons and planets, exploring detailed terrain at a vast scale.
  • Send your Kerbal crew outside their ships for “extra-vehicular” activities.
  • Dock spacecraft together to construct space stations, massive starships, and surface bases on new planets.
  • Use satellites to scan terrain and find biomes and other anomalies.
  • Set up communications networks to communicate between your spacecraft and Kerbal Space Center.
  • Research and develop new technologies to extract valuable information and resources from all over the solar system, and much more!

build mode is buggy, with no advice/ suggestions on how to fix the problem. its so bad that you restart your game from a fresh start it will work building the same rocket. problem happens with prebuilt aircrafts as

Really fun and challenging game, I would recommend this to any space lover. I would use youtube channels to find answers. I play sfs too, so if you played that before it should be less challenging.

Great concept, but the interface is frustratingly unusable. Trying to assemble components - particularly the space plane is a tedious nightmare. Want to mount an engine under a wing? Good luck. Try to move or rotate

I'm not sure where I found 572 hours to play this game in two short months, but uh, yeah, I did. They've clearly coded heroin into it...or something like that. You should buy it. Unless you're a big fat stinky

If you like rockets, you will like this game, and if you dont, you still probably will. This game includes aspects that balance how realistic the game is and how simple it is. You still have to worry about burning in
