[h3]Edit: We've announced that For Science! launches December 19, 2023. Read below for information about what's in the update![/h3]

Hello Kerbonauts!

Some exciting announcements as we enter the chilly months.

In December, we'll release a major content update for Kerbal Space Program 2! In past dev diary posts and video dev chats we've referred to the update as Dot Two or Science. We're thrilled to officially dub this update...

[h2]For Science


We've been sprinkling in sneak peeks of For Science! at the end of dev chats for everyone to digest. While we have more to share in the coming weeks, here are some features to expect from the update:

[h5](Please note all images are work in progress!)[/h5]

[h3]Exploration Mode[/h3]
The For Science! update introduces a new game mode called Exploration Mode. In this mode, you collect and transmit Science from unique biomes across the Kerbolar System; and then redeem Science to unlock new part technologies.

Why is it called Exploration Mode and not Science Mode? In future updates, this mode will allow for resource collection and utilization, as well as the establishment of automated resource delivery routes. We want you to be able to continue the campaigns you start in December through all future colony, interstellar, and resource-gathering updates.


[h3]Science Collection Parts and Interface[/h3]
As the name states, all new Science collection parts help collect Science. These parts are physically consequential, meaning shape and mass should be taken into consideration when building vehicles.




The Science collection and transmission interface gives you the heads-up when there's an opportunity to take measurements or collect a sample. The research inventory gives a detailed view of all Science collected during a flight with clear information about what's been learned and what conditions need to be met to claim Science rewards.


[h3]Tech Tree[/h3]
The Research and Development Center is open! Science can be used to unlock new categories on the tech tree, allowing the creation of more advanced vehicles. You can scout and preview future nodes to plan through dozens of part families.


[h3]Mission Control[/h3]
Mission Control is also open for business - meet Dr. Keri Kerman who will send you on increasingly-challenging quests from learning about basic rocketry to attempting to build and maneuver an entirely new kind of vehicle.


[h3]Heating and Thermal[/h3]
The days of stress-free atmospheric re-entry will come to an end with atmospheric re-entry heating and thermal behavior for parts. When For Science! releases, take those heat shields seriously!


[h3]Wobbly Rockets Improvements[/h3]
We've been hard at work improving the wobbly rockets issue. An enhanced joint system will dramatically reduce wobbliness of large vehicles.

[h3]Aaaaand More![/h3]
We can’t tell you everything, that’ll ruin the surprise!

With this update there will also be significant improvements to quality of life and performance! As we continue development we strive to make KSP2 playable on a wider variety of PCs.

In other exciting news, today we're at Space Creator Day - Creative Director Nate Simpson gave a first look at For Science! to space enthusiasts and creators. He also chatted with creators about the update and answered their questions.

Check out their channels in the coming days for exclusive interviews and gameplay (and because they make great content 🤩):

• ShadowZone
• Matt Lowne
• SpaceExplorerW

Thank you for your patience as we gear up for the update, look forward to more information soon! 💚

[h3]Bug Fixes[/h3]
[h3]Flight & Map[/h3]

• Vastly reduced orbital decay in low gravity spheres of influence [Original Bug Report]

[h3]Other[/h3]

• Certain actions will no longer cause PQS data values to be written to the Windows Registry [Original Bug Report]
• PQS data values added to the Windows Registry in previous releases will now be removed upon launching the game
  

[h3]Known Issues[/h3]
[h3]Remaining Orbital Decay[/h3]
Disabling engine thrust in a low gravity sphere of influence can sometimes cause a miniscule amount of orbital decay. We're working to resolve this issue and will keep the community updated on our progress.

Hello Kerbonauts!

The next edition of Dev Chat is here - sit down with Creative Director Nate Simpson and Senior Engineer David "Trigger" Tregoning as they discuss the wobbly rockets issue and the steps we're taking to improve it.

From Creative Director Nate Simpson:

I hope you enjoyed this chat! Since this conversation took place, David has been developing a tool that allows our team to compare multiple wobbly rocket remedies, including selective wobbliness for certain part categories, KSP1-style autostrut for the entire vehicle, and various flavors of packed vehicle physics. We are testing these now, with the goal of achieving a near-term improvement in vehicle rigidity while developing a more ambitious long-term fix that's performant at all scales. We'll share more information when we've arrived at a balanced solution.

We know you've waited a long time for a solution to this issue, and we're excited to be closing in on a resolution.

Curious as to what's to come? 👀

A hotfix will arrive tomorrow morning that addresses the recently identified critical issue with KSP2 that affects players' Windows Registry.

This fix will both stop the Registry issue from happening and retroactively safely remove extraneous values created by the issue in previous releases.

You can expect the hotfix to be released at 10am PDT.
