- R1.6.3 is live and brings you to Mars - 17 December 2025
R1.6.3 will drop on Steam in the next few hours. This update focuses on the 2020s Mars settlement scenario. It starts by giving the space center a more 2020s feel, with a clearly modernized space base sign and a brand-new launch tower.The historical 1950s-style buildings also received small improvements across all scenarios, including a new staircase, improved windows, and the addition of a Baikonur-style radio tower.Back to the Mars scenario: you now start with all 1960s and 1970s research already completed. The logic around astronaut carrying capacity has also been overhauled. Since the game simulates gravity realistically, astronauts on Mars were previously not strong enough to carry the 80 kg water bottles. Men and women now have different carrying capacities, and men are strong enough to transport those bottles. If you ever wondered why you needed a man on Mars, the answer has some…
- Release 1.6.2 - Language Support and a Few Tweaks - 15 July 2025
Outer Space Shack has been English-only since its launch in summer 2023, but I’ve now added support for multiple languages. This update brings Japanese and French, with more languages planned for future releases. I reworked the interface a bit to handle longer text in other languages, and you can either use your system’s default language or pick one just for the game.I’ve also added a couple of quality-of-life changes. You can now hop back to the rocket list from the rocket details screen and give your rockets custom names. On top of that, I’ve fixed a few bugs and made some minor stability tweaks to keep things running smoothly.

- Release 1.6 is here - First base modules built locally - 29 March 2025
Release 1.6 of Outer Space Shack is now live, bringing major new features to the game! You can now collect scrap metal from leftover landers and asteroids, clearing your landing area of old lander lower stages in the process. This scrap can be repurposed to craft crude parts through a sintering process, allowing you to build station modules. Made from rough metal reminiscent of 19th-century metallurgy, these modules are three times heavier than Earth-manufactured ones to withstand pressure as robust vessels. Best of all, they come equipped to produce food. Release 1.6 also introduces the ability to dismantle and relocate appliances, giving you more flexibility in your base. Plus, quality-of-life upgrades include a new game speed option at x160!
- Game has a new play speed - 2 February 2025
As requested, a new game speed has just been added to the game. There is now the possibility to accelerate time 160x, an intermediate between the x40 and x400 speeds already present in the game. This new speed should be the most approriate when supervizing the active phase of missions on the planets. This new features will be available with Release 1.5 expected in the next weeks.
- R1.6: Recycling Workshops & More - coming later this year - 13 October 2024
Development of Release 1.6 is advancing, focusing on local metallurgy. This video highlights our new recycling workshop, equipped with a laser cutting machine powered by massive condensers and a metal scrap compactor. Local metallurgy facilitates the recycling of lander disposable stages, helping to declutter your base and enabling the construction of modules for hydroponics cultivation using rugged recycled metal. Additionally, asteroid mining will be introduced as a significant source of metal, further expanding your base-building capabilities.
- First Look at Locally Manufactured Space Base Module in Release 1.6 - 8 September 2024
Release 1.6, currently in development, revolutionizes in-situ manufacturing by utilizing recycled materials from disposable lander modules and metallic asteroids. These materials are smelted, machined, and assembled using basic tools to create functional devices. Given the limitations of crude metallurgy, the resulting parts won't match modern aerospace standards. Instead, they'll evoke 19th-century metalwork with large rivets and irregular surfaces. Despite these aesthetic differences, the new in-situ manufactured space base module in Release 1.6 offers a reliable level of security, being five times heavier than those manufactured on Earth. This module is designed to support hydroponics plantations, and plans for a locally-made solar panel support are also underway.
- Announcing Release 1.6 - In-situ base module manufacturing, and beyond - 20 May 2024
Crude base manufacturing The Moon harbors ample metal, as well as in the fixed parts of landers, which some of you may have noticed tend to occupy a significant space over the years. Our next release, R1.6, will focus on metal manufacturing. To source metal, Release 1.6 will introduce mining of asteroids on the Moon surface. Asteroids, predominantly composed of metal—especially iron—provide an easier metal source than lunar regolith. Another method will involve disassembling the fixed parts of landers in a specialized workshop equipped with dedicated tools. A beneficial side effect of this is decluttering the space around your base. The retrieved metal will be processed in a basic smelter to produce small, molded parts, which can then be assembled using simple techniques such as riveting. My inspiration comes from late 19th-century metalwork used in submarines and steam engines. Manufac…
- Release 1.5 is live - 12 May 2024
Release 1.5 focuses on enhancing quality of life and addressing feedback received. New key bindings allow players to customize keyboard shortcuts to their preference, which are saved and can be reset as needed. Unfortunately, astronauts sometimes perish in the harshness of space. Now, deceased astronauts are commemorated in the Space Museum and promptly replaced by a rookie astronaut. We've improved object selection visibility by replacing the previous rectangular UI with a clear silhouette outline of the selected objects. Task management has been enhanced significantly. Players can now set astronauts to a non-working mode, where they will only perform self-care tasks. The task management screen has been updated to allow right-clicking to view or manually assign workers to tasks. While the automatic scheduler efficiently prioritizes tasks, manual control lets advanced players optimize o…
- Release 1.4.1 - 5 March 2024
This update addresses a bug that made it impossible to save a game a second time after loading a save file if a water sensor was installed and its associated prospection task had been completed. With the latest version, what appeared to be corrupted save files can now be successfully loaded, and further saving is enabled.
- Release 1.4 is live - 28 February 2024
Release 1.4 of Outer Space Shack is officially live!

- Patch 1.3.1 is live - 2 January 2024
Patch 1.3.1 is finally live, and I sincerely apologize for the delay in releasing it. Part of the delay was me getting sick for a week, and another part was a technical issue to release the version, which was otherwise ready since Saturday 28th of December. Patch 1.3.1 includes: the possibility for all players to add the Christmas tree to the Moon or Mars base. It requires the solar kiln to be made available through a research project and then installed on the base. The Christmas tree is only available during the holidays season in the game time. there is now a notification when a new research project is available various stability fixes and performance improvements
- Release 1.3 - Water Mining Now Available - 22 November 2023
Release 1.3 - Water Mining Now Available One of the primary challenges of prolonged lunar stays is managing the essential resource of water, particularly for cooling space suits. Water, a critical resource for extended missions, is scarce on the Moon. It rapidly evaporates during the lunar day and only persists in shaded, underground areas. Fortunately, the Outer Space Shack landing site is optimally positioned in high latitudes, offering opportunities to find water behind the northern faces of hills or in deep craters. This update introduces two key pieces of equipment: a water mining sensor for subterranean detection, and a derrick to drill and extract lunar water. These tools, brought from Earth, are highly efficient, capable of extracting up to ten times their weight in water. The yield varies depending on the shade levels of each game tile. Future updates will explore the disassemb…
