Kerbal Space Program patch 1.1.3 is now available!



Hello everyone!

The 1.1.3 patch is now available! We’ve taken our time over the past couple of weeks to tackle as many issues as we could in this patch and the results speak for themselves: close to 100 fixes have been logged compared to the previous version of KSP, and we even found time to hide something small in the game that we’re sure a lot of long time fans will appreciate!

Check out the full changelog at our Forums.

Patch 1.1.2 is now available!



Hello everyone!

We noticed a number of issues persisted through the 1.1.1 patch earlier this week. We’re releasing patch 1.1.2 to address these issues before we head off to a long overdue vacation for the next couple of weeks. Patch 1.1.2 addresses issues with the user interface and landing legs, amongst others.

Check out the full changelog on our forums.

The Patch will start downloading through your Steam client automatically.

About This Game

In KSP you must build a space-worthy craft, capable of flying its crew out into space without killing them. At your disposal is a collection of parts, which must be assembled to create a functional ship. Each part has its own function and will affect the way a ship flies (or doesn't). So strap yourself in, and get ready to try some Rocket Science!

The game offers three gameplay modes: Sandbox, in which you are free to build anything you can think of; Science Mode, which lets you perform Scientific experiments to advance the knowledge of Kerbalkind and further the available technology; and Career Mode, in which you must manage every aspect of your Space Program, including administration strategies, Crew Management, Reputation, as well as taking up Contracts to earn Funds and upgrade your Space Center Facilities (or repair them).

Add to this the ability to capture asteroids (a feature done in collaboration with NASA), Mining for resources out across the furthest reaches of the Solar System, Constructing Bases and Space Stations in and around other worlds; plus literally thousands of mods from a huge active modding community, all add up into the award-winning game that has taken the space sim genre by storm.

Key Features


  • The Vehicle Assembly Building and the Space Plane Hangar allows players to build spacecraft out of any imaginable combination of parts.
  • Fully-fledged, Physics-based Space Flight Simulation ensures everything will fly (and crash) as it should.
  • Take your Kerbal crew out of the ship and do Extra Vehicular Activities.
  • Fly out to Moons and other Planets.
  • Procedural Terrain delivers detailed terrain at a vast scale. The Kerbal Planet is 600km in radius!
  • Mod-enabled, allows players to create new content and modify the game.
  • Ship systems. Keep an eye out for engine temperatures and fuel levels, and try not to explode.
  • Build ships with multiple stages, and jettison parts away as they burn out.
  • Full control over the ship’s setup allows for complex ships and advanced functionality.
  • Dock spacecraft together to build Space Stations, Massive Starships, or even surface bases on other worlds.
  • Manage your crewmembers, hire them, and send them out into space and make them into heroes.
  • Research and Develop new technologies to advance your Space Program.
  • Take on Missions to attract interest in your Space Program.
  • Discover new worlds and expand the scientific knowledge of Kerbalkind.
  • Extract valuable resources from all over the solar system.
  • And a whole lot more!

This is a great casual game for those that enjoy space and physics. Many hours can be poured into this game with no mods and even more once you start exploring what the community has added!

tl;dr:
Kerbal Space Program is a thinking game. You have to consider many variables and factors that affect your rocket's ability to get to space and then consider even more once you get there. It's a tedious game that requires patience and thought to get things right, similar to how one might construct a miniature rocket from a toy store and launch it from a schoolyard, then having to gather the pieces when it comes crashing back down. However, KSP gives players the tools to experiment and design a ship to their liking over and over again without having to pick up the pieces. It even gives players goals beyond simply getting the ship to fly. There's not much here for the player who wants an involved, action-packed experience, but for the player who's looking for video game that captures the essence of crafting a toy rocket and the achievement of going to the moon, Kerbal Space Program is worth the thought, the time, and the money.

KSP is everything I have ever dreamed of and wanted in a sim. It's the perfect combination of adorableness, slapstick, and rock-hard physics. The first time you get a ship into orbit around the Mun, and you see the sunrise over the arc of its surface, I guarantee you will crack a grin.

This game made me haul out my undergrad calculus and physics books to relearn basic mechanics. I don't know what else to say. Play it.

So i told myself when i reached 100 hours on this game i would write a review. Well, here i am.


So i got this game around summmer 2015, after wanting it for a long time.
The game had just left early access and was in beta. (I just want to point out that i am very attatched to this game)
I adore this game. Most of my summer was spent playing this. (Before you say that isn't possible, i would like to point out my hours didn't add up as I ran the game from the .exe rather than steam.)

I would, and have, recommend this game to anyone who enjoys the feel of success, science, exploration, engineering, space, cute green creatures who you shall become the merciless god of as you stack them on top of each-other and use them as landing gear.

The only slightly bad thing about this game is the learning curve. I know the 1.1 update added loads of tutorials, 'cuz the old ones were exeedingly bad, but you will spend around 5 - 10 hours before you can do anything useful. Needless to say though it is worth it, and soon you will conquer the solar system!

Or, y'know, just abuse the various bugs the game has... that's cool....

Anyway, thanks for reading this review. If it helps someone buy the game, or spread the word, or anything, then i'm glad.

This is one of my favourite games. Its simply amazing.

KSP is walking the fine line between a space sciency simulation and a comicly slapstick just for fun and giggles game.

Its harsh and unforgiving in the beginning, expecting you to know about the basic science of rocketry or fail over and over until you get it on your own. (Watch ScottManley tutorials if you want a head start)
I had trouble in the beginning even getting into orbit around the planet (or keeping my rocket upright on the way there) - but now I am planing missions to other planets, landing and returning - sending unmanned rovers to explore - or even bringing asteroids back home.

800 hours in and I feel like I am still just at the beginning.

What starts out as a simple, often hilarious; almost lego-like rocket/spaceplane builder has an astounding depth when you look into the possibilities.

The game features a great incentive for advancing your ambitions, science. Science is spent on new technology and parts for bolder missions, and is earned by pushing your boundaries. First, you can explore around you. Take samples, and crew reports from your cute crew of little green simpletons, then maybe you take a simple rocket to outer atmosphere for the first time, take a crew report and get home alive with a nifty parachute.. and Bam! More science. A new part, and the plot thickens..

KSP begins as a goofy tinkering tool with rockets and develops into a full-blown space exploration and research SIM.
Getting a rock sample from the moon may be one of your hardest gaming achievements, as it was for me, but doing it brings reward like little else. The planning, the development and trial/error makes KSP a great learning tool. It's even NASA approved. It uses real world physics and simulated drag for winged aircraft. It uses realistic orbital-mechanics for planitary manuevers, and players use realistic many real-life elements mission planning.

Buy it for your kids, buy it for yourself. They'll enjoy goofing and experimenting; they might even get serious about it. Same goes for you; you will enjoy at least a few experimental flights/missions. Especially if they end in a giant explosion, as many early flights will. After that you might have a success or two, maybe a simple contract or research mission turns out to be easy and you start learning. Soon you'll have dreams of the stars.
