No Man's Sky Cosmos Update: The Complete Anniversary Guide

No Man’s Sky has just turned ten, and Hello Games is marking the milestone with one of the most structurally ambitious free updates in the game’s history. The No Man’s Sky Cosmos update was announced alongside the tenth anniversary on August 9, 2026, and it takes aim at two boundaries that have defined the game since launch: the walls between star systems, and the stars themselves.

Last updated: August 16, 2026. Hello Games is still releasing Cosmos patch notes in stages, so this guide rounds up everything confirmed so far, flags what has only been reported, and walks you through preparing your save before the full picture lands. We will keep this page current as new details are published.

What Is the No Man’s Sky Cosmos Update?

Cosmos is the tentpole of No Man’s Sky’s tenth anniversary. It arrived through a celebration package including an anniversary trailer and a lengthy open letter from Hello Games founder Sean Murray, reflecting on a decade that produced forty major free updates while players have still explored well under one percent of the universe, by the studio’s account. The reveal landed alongside record player counts.

Murray wrote that the team is busy cooking big things for the future of No Man’s Sky. Cosmos is the first course: an update whose headline promise is flying straight to a different solar system, and even landing on a star. Full patch notes are not out in one document yet, so the timeline below maps how we got here.

Date	Event	Why it matters
February 2026	Remnant update (version 6.22, Expedition 21)	Opened the 2026 update cycle
May 2026	The Swarm update	Brought large-scale space combat against the Hive threat
June 2026	Versions 6.36 and 6.45.1	Added pet battling and a round of stability fixes
August 9, 2026	Tenth anniversary and Cosmos reveal	Sean Murray open letter and anniversary trailer
August 16, 2026	Today	Patch notes still being released in stages

Every Major Feature in the Cosmos Update

The announcement confirmed the headline features directly, while supporting additions have been described in press and community coverage without full official detail. We mark that distinction explicitly because it matters when planning a return.

Feature	What it does	Status
Interstellar free flight	Fly your ship directly toward another star system instead of only warping	Confirmed
Star landings	Approach and land on stars, which were previously skybox visuals only	Confirmed
Heat-resistant technology	New equipment announced for surviving stellar conditions	Confirmed, details pending
Anniversary cosmetic rewards	Celebration items marking ten years of the game	Reported
New base building content	Additional options for base builders	Reported
New music	Fresh soundtrack material, reported to include a piece called the Cosmos Shuffle	Reported

Anything marked reported is expected to be clarified as the patch notes continue to roll out. Treat those rows as directionally accurate but incomplete.

Interstellar Free Flight: Flying Between Systems

Since 2016, interstellar travel in No Man’s Sky has run exclusively through the hyperdrive. You charge warp cells, open the galaxy map, pick a reachable system, and jump. The space between systems was effectively decorative: you could pulse around inside a system forever, but crossing to a neighbor meant warping.

Cosmos changes that rule. The announcement describes giving you the option to fly straight to a different solar system, which would make the void between stars a real, traversable place for the first time. How the game handles the enormous distances involved, whether free flight uses the pulse engine or a new drive mode, and whether it replaces or supplements the galaxy map are all questions the staged patch notes have not fully answered yet. What is clear is the intent: the galaxy becomes a continuous space rather than a chain of instanced bubbles connected by loading screens.

Star Landings and Heat-Resistant Gear

For ten years, stars in No Man’s Sky were scenery, painted onto the skybox, unreachable and unlandable, while all gameplay happened on planets and moons. Community threads asking whether you could ever reach one were answered with a consistent no.

Cosmos retires that answer. Hello Games has confirmed that landing on a star is part of the update, paired with new heat-resistant equipment or technology that pilots are expected to need to survive the approach. Beyond that headline, specifics are still being published. We do not yet know how stellar surfaces behave, what resources or rewards they hold, whether different star classes offer different hazards, or how the new gear is crafted and installed.

Our how to land on stars guide tracks confirmed details, separates them from speculation, and includes a preparation checklist.

Anniversary Rewards, Base Building, and New Music

Around the reveal, coverage pointed to a broader anniversary celebration beyond the two headline systems. Reported but not yet fully detailed in patch notes are anniversary cosmetic rewards, new base building content, and new music, with a track widely referenced as the Cosmos Shuffle.

If the pattern of past milestone updates holds, cosmetics could arrive through channels like the Quicksilver shop, expedition rewards, or login gifts, and building parts would appear in the standard construction menu. That is expectation based on ten years of precedent, not confirmed specifics. Until the patch notes close the loop, treat this section as the softest part of the update.

Why Cosmos Matters for Returning Players

If you drifted away from No Man’s Sky years ago, Cosmos is positioned as the moment to return, for three reasons.

First, it attacks friction. Interstellar free flight and star landings change the two most fundamental verbs of the game, movement and arrival. Systems that felt like sealed rooms become part of one continuous galaxy. Second, the anniversary framing suggests generosity: milestone updates historically ship with celebrations, rewards, and community events layered on top. Third, the 2026 cadence has already been strong, with Remnant, The Swarm, and pet battling landing before August. Cosmos arrives on top of a live, actively updated game, not a dormant one.

One more piece of context: Hello Games’ next project, Light No Fire, is in development, and Murray has framed ongoing No Man’s Sky support as parallel to it rather than winding down. An anniversary update of this scale supports that reading.

How to Prepare Your Save Before Cosmos Arrives

You do not need to wait for the final patch notes to get ready. Almost every prediction below draws on systems that have been stable for years, so the preparation is low risk even if the details shift.

Preparation	Why it matters	Priority
Stockpile warp cells and launch fuel	Any new travel system will likely interact with the existing fuel economy	High
Upgrade your hyperdrive and drive modules	Greater range helps whether you warp or fly free	High
Expand Exosuit hazard protection capacity	Star landings are explicitly paired with heat-resistant gear	High
Bank units, nanites, and Quicksilver	New technology and cosmetics typically cost currency	Medium
Claim unclaimed expedition rewards	Anniversary items may sit alongside existing reward tracks	Medium
Keep a freighter with a stocked fleet	Freighters remain the logistics backbone for multi-system play	Low

Two of these deserve emphasis. Exosuit protection is the most directly relevant preparation, because the only gear detail confirmed so far is that heat resistance is involved in star landings. And do not dismantle your warp infrastructure: the announcement frames free flight as an option, so the hyperdrive is expected to keep its role.

Frequently Asked Questions

Is the No Man’s Sky Cosmos update free?

Yes. Every major update across No Man’s Sky’s ten-year history, all forty of them by Hello Games’ count, has been free to owners of the base game. Nothing in the Cosmos announcement suggests a change to that model.

When does the full Cosmos update arrive?

Cosmos was announced on August 9, 2026 alongside the tenth anniversary celebrations. As of August 16, Hello Games is still publishing details in stages rather than one complete patch note document. Until that document lands, treat any feature list, including ours, as a snapshot of a rollout in progress.

Do I need a new save to use Cosmos features?

No update in the game’s history has required starting over, and every major system has been retrofitted into existing saves. Cosmos is expected to follow that pattern, so your current save should gain access to the new features directly.

Can I still warp the old way?

The announcement describes interstellar free flight as an option, which strongly implies the hyperdrive and warp cell loop remains in place for players who want fast, efficient jumps. Expect both systems to coexist until patch notes say otherwise.

Does Cosmos connect to Light No Fire?

No direct gameplay connection has been announced. Light No Fire is Hello Games’ next, separately developed title that Murray mentioned again in his anniversary letter. Cosmos is a No Man’s Sky update first and foremost.
