Hello everyone!



The European Space Agency (ESA) and Kerbal Space Program have come together to bring you brand new content, including the ESA space-suit texture, new parts and variants, and two of their most iconic and groundbreaking missions into the game. Gear up, fuel up and prepare to share horizons with ESA and KSP!

Kerbal Space Program 1.10: Shared Horizons is the game’s latest major update aimed to continue with our efforts to enrich the KSP experience. Build a kerbalized version of the renowned and powerful Ariane 5 heavy launch vehicle, visit comets and push the limits of space exploration with a host of new additions to the game that not only will give you more things to do, but also make the game look and perform better with a bunch of bug fixes and quality of life improvements.

Let’s go through some of the update’s highlights below:

Thanks to our collaboration with ESA, put yourself to the test and carry out KSP versions of the historic BepiColombo and Rosetta missions! Drop a lander module on the surface of a comet and visit the innermost planet of the solar system to study its magnetosphere and surface characteristics, all in the name of science. Best of all, the Making History and Breaking Ground expansions are not required to play these missions!

In order to make the Rosetta mission possible, comets now roam the Kerbal Solar System. With beautiful tails and larger dimensions than regular asteroids, comets appear in all game modes and you can take on new career mode contracts to detect and visit them. Be vigilant, because you might even see one that is passing through from interstellar space!

Kerbal Space Program 1.10: Shared Horizons includes several new parts and variants to match ESA’s style! Decorate your vehicles with a variety of flag parts that can be attached to your liking, take the brand new Magnetometer Boom along with the MTO and MPO to carry out scientific experiments on Moho or beyond, or capture asteroids and comets with the Advanced Grabbing Unit Jr., a smaller and versatile version of the “Klaw”. Additionally, there are also new variants of some tanks, SRBs, the “Poodle” Liquid Fuel Engine, and decouplers; plus, fairings have not only new variants, but some updated functionality as well.

The legendary green gas giant and it’s innermost satellite have new high-quality texture maps & graphic shaders, and now look sharper and more realistic than ever! Find a nice beach on Laythe and enjoy the view of Jool’s newly animated clouds. Beautiful!
