No Man's Sky Cosmos Patch Notes: Every Confirmed Change
Every confirmed No Man's Sky Cosmos patch note in one place, plus what Hello Games has not announced yet and where to track the official release log.
Cosmos is No Man’s Sky’s tenth anniversary update, announced by Hello Games in August 2026 after ten years, more than forty major free updates, and a redemption arc few games have ever matched. It is easily the most anticipated patch in the game’s history, because it changes the structure of the galaxy itself: you will be able to fly straight to a different solar system and, for the first time, land on a star.
Last updated: August 16, 2026 — the complete itemized patch notes are still rolling out. Hello Games publishes its authoritative changelog on the official release log page, and this article is updated as new official entries appear. Below you will find every Cosmos patch note confirmed so far, clearly separated from what is only reported, and nothing invented. If a change is not on this list, it has not been published yet.
What Is the Cosmos Update?
Cosmos is the summer 2026 update and the centerpiece of No Man’s Sky’s tenth anniversary celebrations. The game launched on August 9, 2016, and the anniversary announcement arrived alongside an open letter from Hello Games co-founder Sean Murray, a tenth anniversary trailer, and coverage from essentially every major gaming outlet. Reporting around the announcement also noted that the game set new player count records during the celebration.
The framing from Hello Games is that this update begins a “brand new era” for the game. After ten years of free content drops that added base building, freighters, exocraft, settlements, mechs, pets, living ships, and far more, Cosmos reaches past planetary content and reworks how you move through the galaxy itself.
Confirmed Cosmos Patch Notes So Far
This table tracks the state of the No Man’s Sky Cosmos patch notes as of today. Status labels matter here: Confirmed means the feature appears in Hello Games’ own announcement materials. Reported means it comes from press coverage of the anniversary and has not been itemized in official notes yet.
| Category | Change | Status |
|---|---|---|
| Interstellar flight | Fly directly to a different solar system rather than only warping from the galaxy map | Confirmed |
| Star landings | Approach and land on a star, protected by new heat resistant gear | Confirmed |
| Suit technology | New heat resistant equipment tier supporting star landings | Confirmed |
| Cosmetics | Anniversary cosmetic rewards for players | Reported |
| Base building | New base-building content as part of the celebration | Reported |
| Audio | A new music track, “Cosmos Shuffle” | Reported |
| Community | Anniversary activity and record player engagement | Reported |
| Bug fixes and full itemization | Complete change list, balance tweaks, and fix entries | Not yet published |
To be direct about what this table does not contain: exact stat values for the new heat gear, acquisition methods, new item names, quest or expedition details, and bug-fix entries. None of that has been published in official notes as of August 16, 2026. Anyone listing specific numbers right now is guessing. This page will be updated daily as the official notes continue to roll out.
What the Anniversary Letter Confirmed
Sean Murray’s anniversary letter is the most reliable primary source published so far, and it put several facts on the record that give Cosmos its context.
| Milestone | What the Letter Established |
|---|---|
| Ten years live | No Man’s Sky launched August 9, 2016 and has run continuously since |
| Forty major updates | More than forty major content updates, all delivered free |
| An unexplored galaxy | Players have collectively explored less than one percent of the game’s planets |
| What is next | “Big things” ahead for No Man’s Sky, alongside continued work on Light No Fire |
| Gratitude | An explicit thank-you to the community for a decade of support |
That last column is worth dwelling on. The letter positions Cosmos not as a farewell patch but as the start of another chapter, which matches Hello Games’ decade-long pattern of using each summer for its biggest release of the year.
Where to Read the Official Patch Notes
When the full No Man’s Sky Cosmos patch notes land, they will appear in the same places every previous update has. Bookmark these rather than relying on summaries.
| Source | What It Covers | Cadence |
|---|---|---|
| Official release log (nomanssky.com) | The authoritative itemized changelog, including hotfixes | Updated with every patch |
| Official news page | Announcement posts and feature highlights from Hello Games | Per announcement |
| In-game patch notes | The changelog shown in the game client on login | Per patch |
| Community wikis | Player-verified details once content is live | Continuously |
A practical warning from ten years of experience: aggregate sites and social posts frequently publish “leaked” or AI-generated patch notes within hours of a major announcement. Treat anything not traceable to the sources above as unverified until Hello Games posts it.
How Cosmos Fits the 2026 Update Line
Cosmos caps an unusually busy year for the game. February brought the Remnant update and Expedition 21. May delivered The Swarm, with its fleet-scale space combat and Expedition 22. June added companion creature battling and was followed by patches 6.36 and 6.45.1 with fixes. Each of those updates followed the same release pattern Cosmos is following now: announcement, staged details, then full notes on the release log at launch.
If you are coming back for Cosmos after time away, the short version is that space combat, ground combat, pets, and expedition rewards all received meaningful attention earlier in 2026, and your existing save carries all of it forward.
Frequently Asked Questions
When does Cosmos release?
Hello Games has announced Cosmos as its summer 2026 anniversary update. The complete patch notes and final release specifics are still being published as of August 16, 2026, so watch the official release log rather than third-party dates. This page is updated as soon as official information appears.
Is the Cosmos update free?
Every one of the more than forty major updates in No Man’s Sky’s ten-year history has been free, and the anniversary letter emphasizes that record. No paid expansion has been announced for Cosmos.
Do I keep my save when Cosmos launches?
Yes. No Man’s Sky updates have always applied to existing saves, and nothing in the announcement suggests a reset. Your bases, ships, freighter, and progress carry forward.
Will Cosmos change how warping between systems works?
Flying directly to another solar system is a confirmed feature, so interstellar travel is changing in a fundamental way. Exactly how the new flight model interacts with the existing warp system has not been itemized in official notes yet. That detail will be added here once published.
Where should I report bugs after the update?
Use the official bug reporting form linked from the No Man’s Sky website. Hello Games historically ships hotfixes quickly after major updates, and hotfix notes appear on the same release log page.
