AST's Mindset
The Mission
Our longterm mission is to develop series productions based on technologies that allow large scale serial production of space components at high quality. With an increasing number of units and streamlined processes the cost of components and devices will be lowered by at least one order of magnitude.
Fast development cycles and component spin-in from commercial application are key to keep the pace of NewSpace projects
Focused
Clear objectives. Maximum impact.
Innovative
Advanced solutions for modern missions.
Reliable
Proven performance in every detail.
