POLARIS Spaceplanes is pursuing a distinctive approach to space launch by combining reusable spaceplane designs with 3D-printed aerospike rocket engines. Founded in 2019 and based in Bremen, Germany, the company aims to offer more efficient and cost-effective launch solutions compared to traditional vertical rockets. Its core innovation centers on the AS-1 aerospike engine, which uses metal additive manufacturing to produce a complex geometry that maintains thrust efficiency across a wide range of altitudes.
The company's development roadmap includes the MIRA demonstrator, which has already completed rocket-powered roll tests and in-flight ignition of the AS-1 engine. Follow-on demonstrators MIRA II and MIRA III are expanding the test fleet. The planned AURORA spaceplane represents the production vehicle intended for commercial and governmental launch services. POLARIS has secured €12.4 million in funding from investors including Capnamic Ventures, Spacewalk VC, and E2MC Ventures, along with support from the European Space Agency's Boost Programme.
POLARIS targets both commercial satellite operators and government agencies needing responsive, reusable launch capabilities. The German Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support is a named customer. The company competes with larger players like SpaceX, Relativity Space, and Stoke, but differentiates through its focus on aerospike engine technology and horizontal takeoff and landing spaceplane architectures. Key partnerships include the ESA Boost Programme and the Aero Challenge Group.
A critical open question is whether POLARIS can scale its 3D-printed aerospike engine to the performance and reliability required for orbital missions, and whether its funding runway is sufficient to reach operational capability against well-capitalized competitors. The company's technical progress with the MIRA demonstrator provides early validation, but the path from subscale testing to a production spaceplane remains long and capital-intensive.
