About the Game
The original Kerbal Space Program is one of the most beloved games of all time and, years after its release, it's bigger than ever before. Its sequel, Kerbal Space Program 2, has been fully redesigned from the ground up to meet the demands of modern and next-generation space exploration, all while maintaining the monumental foundations of the first game. Build a space program, construct powerful spacecraft, and navigate expansive celestial bodies as you explore cosmic mysteries.
Key Features to come during Early Access
Next Generation Technology
As the game updates progress, players will gain access to a whole new set of next generation tools and technology including new engines, parts, fuel, and much more. This new tech will not just create novel puzzles for players to solve, but will also enable new feats of space exploration within and beyond the original Kerbolar System.
Colonies
Brand new to Kerbal Space Program 2 are colonies. Colonies not only pose their own physics challenges, but also require resource gathering to build structures, space stations, habitations, and unique fuel types. Eventually, these colonies become advanced enough for vehicle construction, propelling deep space exploration and beyond.
Interstellar Travel
Next-gen tech, colonies, and systematic resource gathering all lead to a whole new level of exploration: interstellar travel. In Kerbal Space Program 2, interstellar technologies pave the way to a host of new star systems and celestial bodies, each comprising novel challenges and harboring secret treasures. Among them: Charr, a heat-blasted world of iron; Ovin, a ringed super-Earth with relentless gravity; Rask and Rusk, a binary pair locked in a dance of death; and many more to reward exploration.
Multiplayer/Modding
The technological developments made to the foundations of Kerbal Space Program 2 will build on the beloved modding capabilities of the original game, as well as deliver on the long-requested addition of multiplayer. Soon players will be able to share the challenges of deep space exploration. More details on these features will be revealed at a later time.

Bug Fixes
Construction
- Fixed: Moving stages around in the extended staging stack is difficult
- Fixed: Duplicated wheels, wings, and decouplers connected to physicsless parts will occasionally fall off or cause the craft to disassemble when launching the vessel
- Fixed: Loading a craft file with parts surface-attached to other surface attached parts causes parts to show on the floor of the vehicle assembly building
- Fixed: Duplicating a stack in the VAB that includes a decoupler and an engine causes errors when launching the vessel
Flight & Map
- Updated parachute safety and destruction algorithms so that parachutes will not deploy in situations where they will immediately break

- Fixed: If a vessel is decoupled on the ground, launching will cause a permanent 'Landed' state, causing orbit lines to not be drawn
- Fixed: Fairings contacting their base plate after being jettisoned causes a permanant 'Landed' state, causing orbit lines to not be drawn
- Fixed: Using the Teleport to Rendezvous cheat from ground to orbit will cause a permanent 'Landed' state, causing orbit lines to not be drawn

Build 12975719
Dec 19, 2023
KERBONAUTS, WE HAVE LIFTOFF! 🚀
The time is now - For Science! is now available! We're so excited to release this major content update to everyone.
Full release notes for v0.2.0.0 can be found here. We'd love to hear from you about feedback and bug reports on the update - please submit them to the KSP Forums.
Dive into and explore For Science! – and don’t forget to share with us your creations, accomplishments, and discoveries.
To celebrate the release of For Science!, Kerbal Space Program 2 is 20% off until January 4th, 2024 at 1PM ET.
{STEAM_CLAN_IMAGE}/35665816/09baa4795def2516f4e06418ca0fb1908ba9cd79.png
The For Science! update comes with a brand-new campaign type - Exploration Mode, which adds progression and Science collection through missions, experiments, and journeying through the Kerbolar System. Collect and transmit Science from unique locations and redeem it back at the Kerbal Space Center's (KSC) newly opened Research and Development Center to unlock new part technologies, learn novel concepts, and journey further away from the Kerbal's home planet. While working through the tech tree, unlock the means to extend your reach across the Kerbolar System - from right at home on Kerbin, to the furthest regions of Eeloo, and to the murky depths of Eve. Exponential progression ensures that the rewards for your efforts match your ambitions.
{STEAM_CLAN_IMAGE}/35665816/039fea3cb4457264ee299ba878d6951bbddd0a9f.gif
{STEAM_CLAN_IMAGE}/35665816/ef296cd0d9683fceac6504ca51e890dd366d0732.jpg
How will you collect Science? With all new Science collection parts! Integrate these parts to vehicles (be sure to take note of their shape and mass, it matters!) to carry out different experiments, depending on your mission. Keep an eye out for new Kerbal animations when Science gathering during Extra-Vehicular Activity (EVA)!
{STEAM_CLAN_IMAGE}/35665816/0584bfd02064c9b5ea7bc98438473c066b5b9015.jpg
We've overhauled the Science collection and transmission interface for KSP2. During flight, it's now easy to know when there's an opportunity to take measurements or collect samples via a new Experiment Actions button, which provides detailed information about what opportunities are available in your current location. The brand-new Research Inventory gives clear information about how much Science you've already collected and the ability to transmit Science data. The Mission Tracker app helps you keep track of in-progress and completed objectives. New flight planning tools have also been added to the Vehicle Assembly Building (VAB), including altitude and environment-specific readouts that show thrust-to-weight ratio, burn time, and Delta-V for each stage. Data persists and continuously updates in-flight.
{STEAM_CLAN_IMAGE}/35665816/a0b7580277dfc9d1fd808b2519d3de39ea131898.jpg
On your journeys, uncover a wealth of new research locations and mysterious geological formations spread across the Kerbolar System. Locate them and unlock special Science-gathering opportunities - we wonder what you're going to find...
{STEAM_CLAN_IMAGE}/35665816/a62eed083e59580d9514ad715b35889b069593c2.jpg
The days of stress-free atmospheric re-entry have come to an end with the introduction of atmospheric re-entry heating effects and thermal part behavior.
{STEAM_CLAN_IMAGE}/35665816/e4c001ffc9450157f1f6f672dceca44351bf7f00.jpg
We've also made significant quality of life improvements:
- An enhanced joint system has been developed, dramatically reducing wobbliness of large vehicles
- Updated ambient sound systems
- An all-new Boat Dock - complete with cranes and gantries for use both in-and-out of missions. With this comes additional buoyancy improvements!
From us at Intercept Games and Private Division, thank you. We hope you enjoy For Science! and your time amongst the stars!
