We open access to space to improve life on earth

ATSpace designed and manufactured the world's best and first commercial 3D printed hybrid rocket engine combustion chamber. Printing in a single piece reduces costs and enables the highest-performance regenerative cooling design.

Lelien engines leverage 3D printing technolgoy with high-performance copper alloy and uses ultra safe and lightweight hybrid propellant to get to orbit — allowing ATSpace to deliver more satellite cargo per rocket and as a result, offer a cost effective solution.

Lelien Engine

Regeneratively Cooled Hybrid Rocket Engine
Lelien-1A, Lelien-1B and Lelien-1C for stage S3, S2 and S1
Named after the glory Sun King because the Injector works like the Sun rays

Small satellites are here

As satellites have shrunk from the size of a bus to the size of a loaf of bread, the race has begun to build smaller and lower-cost rockets to launch them to orbit.

World's first commercial 3D printed Hybrid Rocket Engine

ATSpace is designing and manufacturing the world's best and first commercial 3D printed hybrid rocket engine combustion chamber. Printing in a single piece reduces costs and enables the highest-performance regenerative cooling design.
The 3D printing technology of Lelien engines utilizes high-performance copper alloy and uses ultra safe and lightweight hybrid propellant to get to orbit — allowing ATSpace to deliver more satellite cargo per rocket and as a result, offer a cost effective solution.
Lelien engine operates at 98% efficiency with minimum residual fuel thanks to the use of 3D printed copper alloy and our unique hybrid technology.

ATSpace is developing the world’s most efficient rocket to deliver small satellites to orbit.
