You can still help us find bugs/issues by reporting them into our bugtracker, but keep in mind that the team's focus is currently on KSP2 development, so bug fixing for the original game has slowed down significantly.

Happy launchings!
Hello Kerbonauts!

Kerbal Space Program 1.12.2 is live!

This patch focuses on fixing over 90 bugs and adding a few improvements to the game, such as a locking functionality to docking node rotations that allows autostruts to cross over docked nodes. We are also adding revamps for the LV-T30 Reliant and LVT-45 Swivel liquid fuel engines. Additionally, and more importantly, 1.12.2 includes the previously-teased Ground Anchor - a brand new element in KSP, that when paired with EVA construction, will give players the ability to anchor their vessels to the ground or create a solid foundation for bases.

Even though we still may release a minor patch here and there when needed, with this patch we are officially completing the 1.12 update, as well as the sustained development of the original KSP, as we are now shifting gears towards the development of KSP2.

Happy launchings!

Hello everyone!

Today we wear our party helmets to celebrate the 10th anniversary of the first publicly released version of Kerbal Space Program, as well as the launch of our most ambitious free update ever! Kerbal Space Program 1.12: On Final Approach is the last major update of what became one of the most influential space flight simulators ever, but it also marks the beginning of a new chapter in the Kerbal universe. Looking forward to the future, but proud of what KSP has achieved, we want to give players our most sincere thanks. The support you’ve given us throughout all these years has helped to excite and inspire us to bring you the ultimate KSP experience before KSP2 hits the shelves next year.

Kerbal Space Program 1.12: On Final Approach is packed with a great deal of content including a brand new ‘Slim’ suit inspired by the feats of the private aerospace sector industry, on-demand disconnecting struts, and rotating docking port collars, just to name a few. This update also includes many new requested features & quality of life additions to improve the user experience of KSP, such as a huge revamp to craft and game save loading menu-system, a large amount of wheel and landing leg improvements, and much more! Rejoice and explore the Kerbal universe once more... you might even encounter some of the new easter eggs and unlockable launch sites scattered around the solar system. Are you ready?

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

Maneuver Creator App
The Maneuver Creator app is an incredibly useful tool that enhances the accuracy of your space maneuvers by allowing you to quickly generate transfers to other celestial bodies, see upcoming transfer windows and get a good understanding of where you’re going and how much deltaV it will take to get there.

Alarm Clock App
Use the Alarm Clock app to set alarms for maneuvers, manual time alarms and alarms for various orbital positions, which will certainly come in handy for those long trips that require several burns to complete.

New Solar Panels
This update also includes 4 brand new photovoltaic panels, including enhanced versions of the SP and OX-4 series, but also two large circular retractable solar panels with very cool deployment methods.

10th Anniversary Fireworks!
Celebrate KSP’s 10th anniversary with these highly configurable firework launchers to attach to your vehicles. Choose from different trail and burst types, but also tweak the force, duration, star size, launch velocity, explosion delay, and the colors of the fireworks at any given time. Let the party begin!

And more!

Happy launchings!

About the Ground Anchor: The Ground Anchor will be a brand new element in KSP, that when paired with EVA construction, will give players the ability to anchor their vessels to the ground or create a solid foundation for bases. Unfortunately we encountered a late bug for this feature, so it will not be included as part of the 1.12 update. We believe we have a fix for it, but it was too late and too risky to do at the last minute. As a result, this feature will be included with the 12.1 patch, so stay tuned.

Welcome to our official newsletter, KSP Loading…! If you want to learn about all the current developments of the KSP franchise, then this is the place to be!

And now, let’s talk about everything KSP!

Kerbal Space Program Final Update on PC
On June 24th, 2011, Kerbal Space Program 0.7.3 was publicly released. Back then the game looked very different with a very limited parts catalogue, no celestial objects except Kerbin which would not rotate, and not even a proper Sun, just a light source at an infinite distance. No one ever expected that this modest game, created by a small studio in Mexico City with no experience in videogames, would turn into a worldwide phenomenon that brought space exploration closer to our households. Therefore it is almost unfathomable that in a couple of weeks we will be celebrating the game’s 10th anniversary. And on that day, we are releasing Kerbal Space Program 1.12: On Final Approach, our 12th major free update!

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.

So what can you expect on June 24th with Kerbal Space Program 1.12: On Final Approach? We’ve already shown a couple of things in our last issue of KSP Loading, and now it is time to reveal the other main changes. So buckle up!

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. 

Alarm Clock App
One of the main features in the upcoming 1.12 update is the Alarm Clock app. With this tool, you will be able to set alarms for maneuvers, manual time alarms and alarms for various orbital positions, which will certainly come in handy for those long trips that require several burns to complete. Additionally, you will also be able to pick alarm sounds to go with your alarms, cool right?

Maneuver Creator App
The Maneuver Creator app is another of the main features within On Final Approach. With it, you will be able to quickly generate transfers to other celestial bodies, see upcoming transfer windows and get a good understanding of where you’re going and how much deltaV it will take to get there. This will cut down time spent fiddling with maneuver nodes and enhancing the accuracy of your space maneuvers, but you’ll need a level 3 tracking station to use it, so you’ll still need those maneuvering skills for your first visit to the Mun.

Wheel Improvements
Wheels have undergone major tuning. We have fixed previous issues with the stress tolerance and we have made some improvements to the suspension and friction model. Additionally, wheels now have a few new tweakable controls that will help reduce how easy it can be to flip rovers and other wheeled vehicles.

10th Anniversary Fireworks!
What better way to celebrate this milestone than to launch bright and colorful fireworks into the air! With this update we will be adding two firework launchers for you to attach to your vehicles - one with 8 bursts, and one with 32 bursts. These pyrotechnic devices will also be highly configurable, with different trail and burst types for you to choose from, as well as the ability to tweak the force, the duration, star size, launch velocity, explosion delay and the colors of the fireworks at any given time. Fill up those canisters and let the party begin!

New Slim Suit
A brand new sleek-looking spacesuit, inspired by the feats of the private aerospace sector will be available with the upcoming update. As with the other spacesuits available in the game, the Slim Suit will be available in three different variations: black and grey, grey and orange, as well as blue and grey.

This covers the main features coming in Kerbal Space Program 1.12: On Final Approach. But there are plenty of smaller ones coming in this update, check them out with us when it releases on the 24th!

Since our last KSP Loading, we also got a preliminary glimpse at the new Kerbal Space Center to be found in Kerbal Space Program 2. It surely looks gorgeous and would make Mortimer, Gene and the rest of the KSC crew proud. Check it out if you haven’t!

Remember, you can share and download crafts and missions on Curse, KerbalX, the KSP Forum and the KSP Steam Workshop.

That’s it for this edition. Be sure to join us on our official forums, and don’t forget to follow us on Twitter, Instagram and Facebook. Stay tuned for more exciting and upcoming news and development updates!

Happy launchings!

Welcome to our official newsletter, KSP Loading…! If you want to learn about all the current developments of the KSP franchise, then this is the place to be!

And now, let’s talk about everything KSP!

Kerbal Space Program Update 1.12 on PC
Coinciding with the game’s 10th anniversary, Kerbal Space Program is getting ready for its 12th major free update since its official release, and it’s going to be epic! This update will be packed with brand new content such as new parts, features, revamps, and more! Buckle up, and let’s learn about some of the content that will be included in this upcoming update.

Eeloo and Pol Texture Revamps
With update 1.12, our effort to revamp all the celestial bodies within the Kerbal solar system will finally come to an end. Eeloo, the distant frozen dwarf planet, and Pol, the smallest natural satellite of Jool, are now looking better than ever with new high-quality textures & shaders. Surely many astronauts will take this opportunity to revisit them and explore what lies within these remote destinations.

Revamped and Rotating Docking Ports
All the docking ports have gotten a well deserved aesthetic revamp. Among the bundle of requested features & quality of life additions we’re including in the 1.12 update, we are giving players the ability to rotate docking port collars added to docking ports. Lining up attached craft perfectly has never been easier!

New Solar Panels
This update will also include 4 brand new photovoltaic panels, including enhanced versions of the SP and OX-4 series, but also two large circular retractable solar panels with very cool deployment methods.

SP-10L 1x5 Photovoltaic Panels
This large retractable solar panel is an enhanced version of the SP series. With a five fold increased solar array area, the SP-10L will provide improved electrical charge generation. This solar panel also includes a case to protect this sensitive technology when it is not being used.

OX-10L 1x5 Photovoltaic Panels
The OX-10L 1x5 is a larger version of the OX-4 series of solar panels. It includes advanced heat radiators, and a deploying bracket to keep the panels safe when launching, although these panels are not retractable once deployed, so beware…

OX-10C Photovoltaic Panels
The crown jewel of the new circular retractable solar panels, the OX-10C provides a great output of electrical charge with a very decent solar array area. When folded it is compact and easy to transport, but although it deploys very graciously, it won’t retract back.

SP-10C Photovoltaic Panels
The SP-10C photovoltaic panel also has a circular design that folds itself on command, making it an excellent alternative if you’re looking for versatility.

Ground Anchor
The Ground Anchor is a brand new element in KSP, that when paired with EVA construction, will give players the ability to anchor their vessels to the ground or create a solid foundation for bases.
The deployable ground anchor will work as other deployable parts, so it will have to be put into a Kerbal’s inventory and then use the deploy functionality to have it successfully anchor itself to the ground in order to build a base from.

Watch a gif of the Ground Anchor in action here.

Kerbal Space Program 2 has also had a few developments since our last KSP Loading.
For instance, last week we released the third episode of the KSP 2 feature series, which delves into Intercept Games' mission to onboard the next generation of space industry experts with new tutorials, UI/UX improvements, quality of life features, and more.

Additionally, in the past few months we have released two additional dev diaries for KSP 2, including a very interesting and informative look into what a game producer actually does in the development process of a title. You can check it out here!

And, if you've ever wanted to dive into the technical side of KSP 2's development, this dev diary goes into the intricacies and challenges of drawing accurate orbits that look stellar, and how orbit tessellation turned out to be the solution to this problem in KSP 2. You can check it out here!

Finally, don’t forget to check out the Kerbal Space Program 2 - Show and Tell Highlights from February & March, where the KSP 2 team has shared some really neat footage of some of the stuff they’ve been working on recently, like new power generation modules for colonies, colony fuel factories, new engine exhaust effects, and some amusing kerbal skin experiments.

Remember, you can share and download crafts and missions on Curse, KerbalX, the KSP Forum and the KSP Steam Workshop.

That’s it for this edition. Be sure to join us on our official forums, and don’t forget to follow us on Twitter, Instagram and Facebook. Stay tuned for more exciting and upcoming news and development updates!

Happy launchings!

Hello everyone!

Gear up Kerbonauts, engineers are required for some in situ reassembling! Stack up your inventory with parts and tools in order to prepare for any contingencies. With a reimagining of the game’s inventory system and the introduction of a new EVA construction mode, KSP is here with new content for everyone!

Kerbal Space Program 1.11: Some Reassembly Required is the game’s latest major free update and with it, we’re adding some significant and game changing elements that give players added flexibility and a more immersive KSP experience. Pack an inventory for your missions and modify your crafts or even assemble a new vehicle on the spot with the help of your engineers, or bring an EVA Science Experiment Kit and have your Kerbals undertake fun animated experiments. In addition to some new parts, visual enhancements, and some bug-fixing, Some Reassembly Required continues to enrich the KSP experience.

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

EVA Construction Mode

This mode gives your engineers tools similar to what you find in the VAB/SPH to manipulate parts in their inventory or within their range while on EVA in any location. Need to make some adjustments to your Vallerian SSTO, or build an improvised Munar rover in situ? Now you can!

Inventory System Changes

This update expands upon the inventory system and gives it deeper meaning and functionality! These changes include the option to carry and stack various parts in your craft’s inventory and adds to the ability of Kerbals to carry an inventory of their own. All while making it easier to get access to and manage all of the inventories on a craft. Just remember to think wisely on what you want to bring with you on a mission…

New Lights and RCSs

Some Reassembly Required adds new lights parts to the game, including some smaller, physics-less lights as well as a couple of deployable lights that work without the need for an attached craft or EC power source. And not only that, two new smaller Reaction Control Systems are being added to the part repertoire! These smaller RCS are perfect to make your probes, drones or smaller crafts more mobile and versatile.

Joolian Moons’ Visual Improvements

With this update, we will continue with the overhauling of the rest of the Joolian satellite system with Bop, Vall and Tylo. These moons have been popular destinations for intrepid space explorers and now they will look better than ever before, with high-quality texture and graphic shaders.

And more!

Kerbal Space Program 1.11: Some Reassembly Required is now available on Steam!

Happy launchings!

Welcome to our official newsletter, KSP Loading…! If you want to learn about all the current developments of the KSP franchise, then this is the place to be!

And now, let’s talk about everything KSP!

Kerbal Space Program Update 1.11 on PC

Kerbal Space Program 1.11: Some Reassembly Required is being released this winter (well, winter in some parts of the planet). With it we are not only including a number of quality-of-life features, the Joolian moons visual enhancements, and some new parts - as we talked about in the past issue of KSP Loading - but also some more significant and game changing elements that give this update its name. Buckle up and let’s get into the details of Some Reassembly Required!

EVA Construction Mode
EVA Construction Mode is the main feature included in Kerbal Space Program 1.11: Some Reassembly Required. This allows Kerbal engineers to adjust many parts on a craft while on EVA.

The tools at your disposal while in this mode are similar to what you find in the VAB/SPH, such as place, rotate, and move. You can also visualize the center of mass, center of thrust, and the center of lift for a vessel. However, there are of course some limitations:

An engineer will only be able to adjust parts that are within their range, whether these are on a vessel, inside nearby storage containers, laying around in their proximity, or in their own inventory slots.

Only parts below a certain weight threshold will be able to be manipulated, but constructing in lower gravity allows a Kerbal to build bigger! Kerbals can only manipulate one part at a time and only construct with attachable parts; for example, a deployable experiment will not be able to be attached to a vehicle in this mode. Finally, some parts are just too bulky to build with and will stay right where you left them.

Another key consideration is that during Construction mode, the game is not paused, so you’ll be able to move your Kerbal around, and you’ll have to mind your surroundings - maybe attempting to reassemble your spaceship during re-entry is not a great idea.

Inventory System Changes
Back in 2019, in update 1.7, we introduced cargo parts and inventory to the game in order to allow Kerbals to carry and deploy science equipment in the Breaking Ground expansion. The base game, however, did not make much use of this feature, until now... With update 1.11 we are expanding upon the inventory system and giving it deeper meaning and functionality! These changes include the option to carry and stack various parts in your craft’s inventory and expand upon the ability of Kerbals to carry an inventory of their own. Let’s go into greater detail on each of these functions.

New Inventory Functionality
We’re extending the inventory functionality with a few new tweaks: players can now stack small parts in an inventory slot, inventories measure the volume of all parts - as a limit on how many parts can fit in an inventory, and many more parts can now be put into an inventory, to support the construction feature.

Cargo Mode in the VAB/SPH
Cargo mode makes it easier to get access to all of the inventories on a craft. Available in the VAB/SPH, Cargo Mode opens a panel showing the different inventories available in a craft and what’s been assigned to each, and quickly places items in any inventory on the craft. The part toolbox is also filtered down to just parts that can go into an inventory.

Kerbals & Inventory
With this update each Kerbal will have two inventory slots. Moreover, Parachutes and EVA jetpacks are now inventory items, giving more flexibility on how you equip your Kerbals. If a Kerbal is not carrying the jetpack or the parachute, these won’t appear on their back. Kerbal mass & crewed parts have been adjusted to account for all of these changes.

Cargo App in Flight
While in flight, the Cargo App gives access to all inventory slots on the craft. Clicking the app icon will open a panel that shows all craft inventories.

Part Repairs
We are adding repair kits, a new cargo part which engineers use to repair breakable parts on site, including deployable solar panels, antenna, wheels, radiators, robot arms, etc.

EVA Science Experiment Kit
While on EVA, a crew member can use the EVA Science Experiment Kit to run some fun situation-based experiments by accessing the Kerbals part action window.

If the right conditions are met the Kerbal will play one of three pretty cool animations and collect science for that science experiment, including testing the bizarre Dzhanibekov Effect!

New contracts
We are including three new contract types to make use of the new features within Career Mode. For example, you can take on a contract where you’ll be asked to find and assemble a damaged rover and then drive it to a designated waypoint.

Remember, you can share and download crafts and missions on Curse, KerbalX, the KSP Forum and the KSP Steam Workshop.

That’s it for this edition. Be sure to join us on our official forums, and don’t forget to follow us on Twitter, Instagram and Facebook. Stay tuned for more exciting and upcoming news and development updates!

Happy launchings and happy Thanksgiving!

Welcome to our official newsletter, KSP Loading…! If you want to learn about all the current developments of the KSP franchise, then this is the place to be!

First of all, we hope all you Kerbonauts are safe and well during this pandemic. These times have been difficult for most and in such times it’s important to hang in there, do our part, and follow hygiene and safety measures to help stop the spread of this virus. Our hearts go out to those who have lost someone or their livelihood during these difficult times. Like everyone else, we have had to adapt to the current circumstances, but it hasn’t stopped us from continuing our work and hopefully bringing players some relief and joy with regular updates that keep KSP fresh and fun to play. Our best wishes to all of you, hang in there, and stay safe.

And now, let’s talk about everything KSP!

Kerbal Space Program Update 1.11 on PC

If you’ve been following us on our social media channels, by now you’ll know that we are currently working on KSP’s next major update, Kerbal Space Program 1.11: Some Reassembly Required! In this KSP Loading we’ll talk about the suite of quality-of-life features that we’ll include in this update to improve the game experience, as well as our continuous effort to revamp the textures of all of the game’s celestial bodies, plus some new light parts that will brighten up your day.

Joolian moons get a revamp

With this update, we will continue with the overhauling of the rest of the Joolian satellite system with Bop, Vall and Tylo. These moons have been popular destinations for intrepid space explorers and now they will look better than ever before, with high-quality texture and graphic shaders. As we’ve done with all of the revamped celestial bodies, players will be able to switch between legacy and high-quality options. Take a look at these previews and start preparing your next mission to these mysterious, yet beautiful moons!

New Light Parts

Illumination variety has been fairly limited in KSP so far, with only 2 light options available in the game, but with this update we’re changing that. Some Reassembly Required will add new lights parts to the game, including some smaller, physics-less lights, that will allow players to further customize their creations. These will also come with a white and black trim variant to match with different craft styles.

Additionally, we’re including a couple of deployable lights. These are lights that can be deployed, just like deployable science parts, and will work through the use of an unbelievably efficient integrated solar/battery/LED system without the need for an attached craft or EC power source

Let’s get those lights on and see what creative contraptions you can come up with these new light parts!

New RCSs

Two new smaller Reaction Control Systems are being added to the part repertoire: The RV-1X Variable Thruster Block and the Place Anywhere Linear RCS Port. Additionally, both the RV1X and the classic RV-105 Thruster Blocks are getting 5-, 4- (the original configuration), 3- and 2-horned Orthogonal variants. These smaller RCS will be perfect to make your probes, drones or smaller crafts more mobile and versatile.

Quality of Life Features

As mentioned above, we want to include several QoL features within this update, some of which have been drawn directly from player feedback. These include the following:

Warp to Sunrise
We are adding a new button alongside the Warp arrows that when clicked will warp the game until the sun rises over the currently visited celestial body for the landed vessel. That way players won’t ever miss those sunrises.

Improved visibility for the map filter
We are improving the visibility of the map filters, too. Currently there is no on-screen indication of this functionality and players have to discover it on their own. Now access to these tools will be visible in plain sight and readily available for all players to use at will.

Landed Part/Vessel anchoring
A side-effect of the game’s physics has caused some headaches by having vessels without landing legs or wheels to slowly slide when they are resting on the ground under different circumstances such as steep slopes. To help the players deal with this, we will be adding a new internal function to vessels to help anchor themselves to the ground. Similarly, we have improved Kerbal friction, which basically means that our little green astronauts won’t slide so easily from steep slopes either.

KAL improvements (Breaking Ground)
For Breaking Ground players, we’re also making some improvements to the KAL that will allow for more complex robotic setups, such as the ability to enable/disable a KAL on a craft as an action. Moreover, Kerbals on EVA will be able to activate KAL on crafts if on-the-spot adjustments are needed. These simple, yet significant changes will certainly help to exploit this powerful tool better, letting players have more control over their contraptions.


Kerbal Space Program 2 is a very ambitious project and everyone at Private Division and Intercept Games is committed to delivering the best possible experience to KSP fans. For this reason, Nate Simpson, Creative Director of KSP 2 informed the community last week about the decision of releasing KSP 2 in 2022 instead of fall 2021.

Nate Simpson, Creative Director of KSP 2:
We knew we were taking on an immense technical and creative challenge when we started this project. We’ve heard time and again from this community that quality is paramount, and we feel the same way.

In the meantime, we’ll continue to post some previews, feature videos and dev diaries to keep everyone up to date. In fact, recently we got a brand new entry to the KSP 2 Developer Insights series. Titled Kerbals, The First New Look, this developer insight was written by Intercept Games’ 3D Animator & Content Engineer, Paul Zimmer, who talks about the wide range of personality and emotional traits that Kerbals will display in KSP 2. We highly recommend checking it out if you haven’t done so already.

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:

ESA Missions
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!

New Parts and Variants
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.

Jool and Laythe Visual Improvements
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!

And more!

Kerbal Space Program Update 1.10 on PC

As most of you know by now, we are currently working on the final details for the 1.10 release. Launching on July 1st, Kerbal Space Program 1.10: Shared Horizons is special in many ways. For starters, we have partnered with the European Space Agency (ESA) to bring two iconic and historic missions to the game, BepiColombo and Rosetta, as well as a bundle of brand new parts and variants to resemble the components of their real-life counterparts. In addition to that, we’re bringing ESA’s spacesuit and the Ariane 5 heavy-lift launch vehicle into the game. Coupled with that are new planet and part revamps, performance improvements, a bunch of bug fixes, as well as a few quality of life features. We'll be going into more details about this exciting update, so buckle up.

ESA Missions
Thanks to our partnership with ESA, we’re bringing two of their most impressive and groundbreaking missions to KSP for you to experience for yourself in the upcoming Shared Horizons free update. Best of all, these missions will be available for all to play, regardless of whether or not the player owns the Making History or Breaking Ground expansions.

Arianne 5
For these missions, you’ll be equipped with an Ariane 5 analogue, which we teased a few weeks ago. This brings to Kerbin a version of ESA’s premiere heavy lift launch, capable of putting over 20 tons into LKO. Based on your feedback, we did some adjustments to the fairing and the second stage to better resemble the look of its real-life counterpart.

BepiColombo and BepiColombo Spacecraft parts
Like JAXA and ESA’s joint endeavor, in this mission you’ll visit the innermost planet of the solar system to study its magnetosphere and surface characteristics. Launch from the KSC with a kerbalized Ariane 5 and deploy the Moho Transfer Module (MTM), which will carry the Moho Planetary Orbiter (MPO) to its destination using ion thrusters. You'll have access to the new Magnetometer Boom to carry out scientific experiments on that distant planet. Just like humans in our world will go on making further discoveries about Mercury, what mysteries will Kerbals learn from the planet orbiting nearest their star?

Rosetta …and Comets!
Just like its real-life counterpart which launched in 2004, in this mission you’ll intercept a comet and drop the Philae lander module on its surface. This means not only that you’ll get to perform an amazing and challenging mission, but that we have added comets to the game, including new career mode contracts to detect and visit them! Comets will appear in all game modes and have a very distinct look from regular asteroids with gorgeous tails and larger dimensions. With some luck, you might even see one that is passing through from interstellar space!

Suit picker
We’re including an improved suit picker in the 1.10 update, so you can easily dress your Kerbals to your liking. When clicking on the hanger icon of the crew tab, you’ll not only be able to choose any of the different EVA suits available across the base game and the expansions, but also decide whether you want your kerbals to wear the veteran, IVA or EVA color combinations of any of the suits - including a new ESA suit texture option! This feature will also make it easier for modders to add their own suit textures to the game.

Flag parts
You probably noticed that the Kerbal’s Ariane 5 we previewed a few weeks ago is decorated with a variety of flags. As some of you have guessed, we’ve added flags as surface attached parts that you can now add to your vehicles, for those multi-mission or multi-agency crafts. You’ll be able to place the flags horizontally and vertically, on curved and flat surfaces, plus choose the size and whether you want to place a white, dark, orange or transparent background for them.

Advanced Grabbing Unit Jr.
We’re introducing a new smaller version of the Klaw, a device whose primary purpose is to capture asteroids and basically anything it can put its claws around, maybe even comets. This new version has a radial size of 0.625m in contrast with the original’s 1.25m. Thanks to its size, this smaller unit will be quite versatile, plus we’re including a second darker variant for it. We’re curious to see what the community will contrive with the Klaw Jr.

New part variants & improved control over Fairings
We’re including several part variants for the Shared Horizons update in order for some parts to match with ESA’s style. These include variants for fuel line, struts, fairings, as well as for the Baguette, Dumpling and Doughnut external fuel tanks, among others.

Fairings have gotten an upgrade as well, making it easier to set up open-ended fairings, and now you can fine tune the shape of your fairings better as well.

S1 SRB-KD25k “Kickback” Solid Fuel Booster
This heavy solid rocket booster is getting a variant so that it can provide your Ariane 5 that additional thrust needed to launch your probes and modules to outer space.

Rockomax X200-32
The Rockomax X200-32 Fuel Tank is also getting a third ESA variant for it to match the Ariane 5 color scheme.

Planet Revamps

The legendary green gas giant has received a major revamp. Jool did not only receive high-quality texture & graphic shaders, but also animated clouds, which are particularly beautiful when time-warping around this colossal green sphere.

Jool’s innermost natural satellite is also getting a well-deserved visual makeover. The new high-quality texture maps and the proximity to Jool will surely make Laythe one of the most coveted destinations for those Kerbonauts who just want to enjoy a nice view at a beach.

Remember, you can share and download crafts and missions on Curse, KerbalX, the KSP Forum and the KSP Steam Workshop.

That’s it for this edition. Be sure to join us on our official forums, and don’t forget to follow us on Twitter, Instagram and Facebook. Stay tuned for more exciting and upcoming news and development updates!

Happy launchings!
