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 On Final Approach-PLAZA
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.
Kerbal Space Program 1.12: On Final Approach is going to be special in many ways. We are not only packing this free update with a massive amount of new content, player requests and all sorts of fixes, but it is also our thank you letter to everyone in our community who supported us along the way and made our dreams come true. Unfortunately, all good things must come to an end, or rather move on to the next chapter. So yes, On Final Approach is the last major planned release for Kerbal Space Program. While there may still be occasional minor updates to address bug fixes as needed, Squad's efforts will now shift towards joining Intercept Games in the development of Kerbal Space Program 2.
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!
Craft and Save Loading Improvements
On Final Approach includes a huge revamp to craft and game save loading. Search, foldering, and cross-save access are added to craft loading in the editor, and search has been added to craft loading on the launchpad/runway and to the quicksave loading dialogue. This will help you to better sort out your saved craft and games, especially if you have a ton of them. This feature will also allow you to load or save craft with different game saves.
