Power the rocket. Propel the mind. Engine hardware and the language of propulsion, brought together.
Upcoming / Engineering & propulsion
Getting to the Moon is only part of the story. Approach, insertion, and the art of staying in orbit.
Upcoming / Flight heritage
Look back at home. Lunar spacecraft and a familiar world seen from an unfamiliar place.

After the launch comes another kind of exploration: finding flight hardware beneath the surface.
About Astrinum
Astrinum makes technical spaceflight apparel around the machines, missions, and engineering that reward a closer look.
Our point of view
A rocket is more than a silhouette. A spacecraft is more than a symbol. Our designs begin with subjects worth understanding.
Our approach
From staging to ocean recovery, we pair the artwork with a readable explanation of the idea behind it.
Who it is for
Builders, engineers, students, enthusiasts—and anyone who wants to ask one more question about how it works.
