Kerbal Space Program 1.7.2 is live!

Hello everyone!

Kerbal Space Program 1.7.2 is live!

In this patch we focused mainly on improvements and bug fixes for the Breaking Ground Expansion. We’ve included an animation for Kerbals when they interact with Deployed Science experiments, added sound effects to Laythe’s Geyser and the Cryovolcano on Vall, and some new color variants for the robotic parts. Additionally, now it will be easier to encounter surface features on celestial bodies. However, there’s a very remote possibility that some of the newly generated surface features could appear where an existing craft is positioned. So, although this is unlikely to happen, we do recommend creating a back-up. There are also bug fixes and a few improvements for the base game, particularly for the new axis group system. Now you’ll be able to tie the main throttle to an axis group.

Check out this patch's Changelog for further details:

========================================= v1.7.2======================================== 1.7.2 Changelog - BaseGame ONLY (see below for Breaking Ground changelog) +++ Improvements * Redesign the Action sets icon during flight to make the current action number more visible. * Made engine thrust limit, and cargo bay deploy limit, and control surface and airbrake authority limits bindable to axis groups. * MainThrottle axis can be bound, but only in absolute mode. +++ Localization * Fix shadow casting string not displaying correctly if player doesn’t have the Breaking Ground Expansion. * Localize the strings for the Axis Actions in the Settings under the vessel Tab. +++ Parts +++ Bugfixes * Fix kerbal flags clipping into backpacks. * Fix lowest part of vessel calculations for Wheels when coming off rails. * Fix localisation for survey waypoint contract objectives. * Fix NRE in maneuver node editor. * Fix PAW displayDirty not working in the editor. * Fix symmetry counterparts (bow-tie) autostrutting. * Fix cutoff string in recovery science report screen. * Fix null reference on ship load when parts have changed their attach nodes. * Fix missing string in Absolute Control / Incremental Control tooltip. * Fix science value of repeat experiments. * Fix EVA portrait clipping in some situations. * Fix EVA portrait texture being transparent +++ Mods +++Miscellaneous 1.7.2 Changelog - Breaking Ground DLC ONLY +++ Improvements * Implement random orientation for surface features. * Add a scale variable in the rocsdef.cfg. * Increase unfocused range on deployed science Part Action Windows to 20m. * Add screen message for seismometer science if in sandbox game. * Kerbals can now change their future suit emissive colors via their PAW and persists to save game roster. * Kerbals can now interact with Deployed science parts (interaction animation). * Increased interaction range of science experiments on arms so that they match folded arm length. * Add Robotics radio button to SteamWorks Craft exporter.

About This Game

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 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.

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!
