Last Verified: September 2026 | No codes. The suit and backpack unlocks come from finishing missions.
If you came looking for a working Mission Mars code, there are none. There is no code box in the game, and the Museum of Science in Boston, which made it, has never run one.
People search for codes here because of the free astronaut suits and backpacks. You do get those, but you earn them by completing missions, not by typing a code. This page explains where each unlock comes from.
Active Mission Mars Codes
There are no codes. None active, none expired, and no menu anywhere in the game to type one into.
A museum built this game to teach kids engineering. The suit colors and backpacks are the reward for finishing a mission, so the unlock is proof you did the work.
Codes are case-sensitive in the games that have them, so a failed code is often a typo. Here nothing works because there is no box.
If that ever changes we will update this page. The full list of missions and what each one unlocks is on our wiki.
The Unlocks Come From Missions
Every cosmetic in Mission Mars is tied to something you do.
Some suit colors unlock when you first try a mission. Some come from completing one. A few need you to help with the Mars missions a set number of times.
None of them need a code. If a guide tells you to redeem something for a suit, it is describing a different game or it is wrong.
There is no shop and no currency to spend either. The game is fully free, funded by the museum, so there is nothing for a code to discount.
Our Mission Mars wiki lists the missions, the badges and the real Mars places you drive.
How to Redeem Mission Mars Codes
There is nothing to redeem and no box to redeem it in. Any guide showing you where to click was written about a different game.
If a code system ever appears, here is where Roblox games usually put the box.
1Open the settings or menu panel. On most screens the button is in a corner.
2Scroll to the bottom of that panel and look for a Codes tab.
3Paste rather than type, because codes are case-sensitive.
4Press redeem and watch for a confirmation on screen.
5If there is no box in the menu, the game has no codes. That is where this one stands.
When Do New Mission Mars Codes Come Out
There is no honest way to guess, because there has never been a first one.
A code system is something a game adds so it can hand out rewards later. This game already hands out its unlocks through the missions, so there is no gap for codes to fill.
The game still gets small updates, like the Dust Dash mission that was added later. But a code box does not fit how it is built.
Until that changes, ignore any list you find. Save this page and come back rather than searching again.
What Is Free in This Game Instead
Astronaut suits and backpacks from missions
You unlock suit colors and backpacks by trying and finishing missions. They are real Roblox items you can wear anywhere.
The whole game
Every mission, the rover builder and the social hub are free. There are no game passes at all.
A real engineering lesson
The build, test and retry loop the game teaches is the real Engineering Design Process. Learning it here costs nothing.
Real Mars, from NASA data
The map uses real measurements, and Arsia Mons and Planum Boreum are named after real places on Mars.

About Mission Mars
Mission Mars is a free educational Roblox game commissioned by the Museum of Science in Boston and built with the studio Filament Games. It teaches the Engineering Design Process by having you build and retest a Mars rover.
It launched in December 2022, the first game funded by the Roblox Community Fund, and has passed nearly 8 million visits. Roblox lists it under Learning and Explore.
The game has no game passes, no code system and no scripts. Everything in it is free, and the museum funds it.
