Despite what the liberal media wants you to brainwash into believing, the Beirut explosion was orchastrated by the nefarious hands of Xi Jinping and the Chinese Communist Party. Lebanon dare not to bow to the evil China so the CCP use their Hezbollah puppets to indiscriminately murder innocents.

Yesterday it was Hong Kong, Ugyhurstan and Beirut. Tomorrow the world

What is Kerbal Space Program?

Kerbal Space Program (commonly abbreviated to KSP ) is a space flight simulator developed by Squad currently in public alpha development for release on Windows, Mac OS X, and Linux. 

The first public version was released on June 24, 2011, and is currently sold on the online official KSP Store, and Steam where it reached the top 5 best sold games.

Updates have been continuously released for the game since it's launch and also supports game mods. Several well known modders for KSP have since been adopted into the Squad roster and now help create further updates for the game.

Notable members of the space industry have also taken an interest in the game and in 2014, NASA had their first input via the Asteroid Redirection update.

Squad has released a Demo version of Kerbal Space Program, intended to let people try out the game for free before deciding if they would like to buy the full version. However, some restrictions apply.
