Because regolith doesn’t care about clean designs.
🧪 Product Overview
The Space Is Dirty™ T-Shirt is for the people who build hardware for environments that fight back.
Designed for scientists, engineers, and space enthusiasts who work with regolith simulants, ISRU systems, and simulated space environments, this tee represents a simple truth: space hardware gets dirty, and serious testing embraces that reality.
Featuring a clean SRT logo on the front and a bold “Space Is Dirty” graphic with an astronaut on the back, this shirt is equal parts statement, signal, and uniform for the people doing the real work of space development.
🚀 What “Space Is Dirty” Means
This phrase isn’t branding fluff — it’s lived experience.
Space Is Dirty stands for:
-
Regolith that abrades, clogs, coats, and contaminates
-
Hardware testing that reflects real lunar and Martian conditions
-
High-fidelity simulants over idealized assumptions
-
ISRU development grounded in geology, physics, and material truth
-
Innovation built through abrasive, dusty, unforgiving test environments
If you’ve ever worked in a simulant bin, a lunar testbed, or a planetary analog environment — this shirt speaks your language.
🧑🚀 Who This Shirt Is For
Perfect for:
-
ISRU engineers and researchers
-
Scientists working with regolith simulants
-
Space hardware developers and test engineers
-
Planetary surface systems teams
-
Students and professionals pursuing careers in space resources
-
Anyone who understands why dirty testing leads to flight confidence
It’s instantly recognizable to the people who know — and invisible to everyone else.

🔬 Why It Matters
Space hardware doesn’t get tested in theory.
Dust doesn’t behave politely.
And confidence is earned in simulant, not PowerPoint.
This shirt represents the people who:
-
Design for abrasion, contamination, and wear
-
Test hardware the way it will actually be used
-
Trust data over assumptions
-
Build systems meant to survive the Moon, Mars, and beyond
⚠️ Notes
-
Apparel item only (no simulant included)
-
Designed for everyday wear
-
Represents the Space Resource Technologies ethos
