Kerbal Space Program is a space flight simulator videogame developed and published by Squad. When playing, you will have to create your own space program and make it successful. Kerbals are a race of small green creatures whose only dream is abandon the simplicity of Kerbin (their home world) and travel through space. They are not what we can call experts in engineering or aeronautics, but their willingness and enthusiasm will lead them to at least try it.

Nevertheless, don't fool yourself; the cartoon-like graphics and funny soundtrack can make you think that everything is fun and entertainment. You could not be more wrong if you fall into that trap. The game is focused on physics and real science. You must have the basics of real aeronautics to help those cute Kerbals. This way, you will be supposed to know things about gravity, centers of thrust, orbital eccentricity, inclination, etc. You need knowledge about spaceships and engineering vocabulary, too. Thus, terms such as periapsis and opoapsis will appear, as well as sections requiring trigonometry.

At first glance, it can seem easy, but Kerbal Space Program is a real flight simulator, and so, it requires serious thought, but always with the fantastic sense of humor that the Kerbal creatures provide to the game. Nevertheless, don't worry because even it requires some "difficult" knowledge, you will learn everything you need when playing, after all, it is a videogame.

Explore the universe!

Kerbal Space Program is a construction sandbox that serves as space flight simulator. You will have to put together several items to build a proper space rocket. Nevertheless, your rocket does not always work, so you will have to do numerous attempts before even thinking about sending a poor and innocent Kerbal to the "Mün". You will have to think about the design of your rocket, the items you want it to have, all the necessary elements to make it stable etc.

Kerbals are a race of small green creatures whose only dream is abandon the simplicity of Kerbin (their home world) and travel through space

Once you have planned the design, put all the pieces together and test the rocket. Put the theory into practice and watch how your rocket works. If it works as you expected, you can send a Kerbal. Take into account that gravity affects your rocket, as well as the ozone layer, the pressure, etc. Everything has to be taken into account in order for your work to be successful. Even the smallest of the changes in your design can lead to an error that causes the massive destruction of your spaceship.

System Requirements

The minimum system requirements to download Kerbal Space Program to your PC are the following:

  • Operating System: Windows XP or later

For what are you going to use the program?
  • my friends said that this game is awesome so i went out to check if its true so thats why im here and also i wanted to be an astronaut some day

  • This will be used for educational purposes. I am using it for a very important engineering class at a local community college here in Houston, Texas.

  • I want to use the program for fun, leisure, intellectual challenge and creativity especially also as a learning tool for my 8-yr old son, Ian.

  • This game has always been interesting for me to watch but I never really knew if it was worth the money, considering the learning curve I wasn't completly sure if I would just get frustrated and quit.

  • I am going to use this software to play one of my favorite computer games Kerbal Space Program, but i dont have the money to pay for it so this will do

What similar programs have you used?
  • all of the programs and that is really fun because without having this program i will not be able to complete my project that has taken me ok

What do you like most about this program?
  • the program runs smoothly and has a wide variety of parts and interactive items allowing for long sessions of builds without having to recreate the same thing twice

  • its amazing and if i didnt hae this game in my life i would never had realised the meaning of fun, this games is so good that i dont think ill ever be able to leave it

  • Because it complicates your brain to try and build your best rocket,while using real life quantom physics and really hard confusion waves...

  • It is a great thing and alot of people seam to like it so thats what ilike about it. I would recommend this to anyone i know because its good

  • It is a very cool program i love it to bits an d i ate the pizza with a chicken talk + Pewdiepie = Jacksepticeye and Cinamontoastken eats dinner

This I must say to some extent is somehow a game that is designed for some space like missions and for me the way that I saw it is like developed by scientists because when I downloaded this game first of all I thought that it was kind of an easy game but I can’t lie but it was quite very challenging for the game main objective of this game is to achieve high success in creating a solar system in a certain planet that is filled with people who are kind of green in color and they are known as kerbals and then you must develop a space and also you must be able to have explorations in the space that you have been able to develop.


The features are

Be able to create a complex space system

Achieve various missions in the game

Go for explorations


It is a very complex game.


  • It is very interesting to explore in the game
  • The missions are great to explore


  • the game is very hard to play

Kerbal Space Program

Before Astronaut Neil Armstrong was sent out to the outer space by the Americans, a lot of hard work, research and study were done. Scientists had to study the nature of the outer space, the forces of nature like gravity, centers of thrust, orbital eccentricity and inclinations etc. It is pure science and requires scientists with proper knowledge including engineering, aeronautics etc.

This is what Kerbal Space program tries to achieve, but it is only a video game which must also provide fun and entertainment. It is a space flight simulator game featuring the Kerbal creatures. They are a race of small green creatures bored of their simple world Kerbin and want to explore into outer space. These creatures provide a lot of humor in this game as they are plain funny.

The design of this videogame looks cartoonish like. The Kerbal space program is a construction sandbox serving as space flight simulator. You have to put up together several items to build your spaceship. For you to put in a Kerbal in as the Americans did with Armstrong, you have to do tests until you are satisfied it is ready for takeoff. You do not want to end with a dead Kerbal or a destroyed spaceship.


  • Everything about the game is full of humor and fun
  • It is easy to play and install


  • The graphics do not seriously portray a serious space flight program



A very unique and interesting space program simulator that is a must try

I recently came across a space program simulator called the Kerbal Space Program Simulator. I’ve always been interested in the different sciences and astronomy all my life, so downloading and trying out the game was a no-brainer for me. Kerbal Space Program is described by the developers’ as a space program simulator.

As the player, you’ll be in control over the space program of a race of green human-like beings called the Kerbals. Set in Kerbin, a fictitious Earth-like planet on a solar system much like our own, your goal is to create a fully functional space mission, from start to finish. This means you’ll have at your disposal, a space center or space port, space crafts, including rockets and boosters, and many other auxiliary aspects and components necessary to carry out a space mission. Space missions range from the very simple, such building a spacecraft and achieving orbit, to the very complex, such as interplanetary exploration and building of space bases.

As I played the game, I realized that it requires quite a steep learning curve, since there are many technical aspects that must be considered, especially when creating the more complex space missions. However, for those who are really interested in astronomy and space flight, Kerbal Space Program is a game that will provide hours and hours of endless fun.


  • A unique space program simulator game
  • Very complex game aspects mean an almost endless range of space flight scenarios


  • Many of the game’s physics are not realistic
