About us The German aerospace start-up POLARIS Raumflugzeuge GmbH is developing a revolutionary reusable space launch and hypersonic transport system that operates like an aircraft. Based on more than 30 years of German and European spaceplane research, the development of the spaceplane AURORA began at the German Aerospace Center DLR. Aurora combines aircraft and rocket launcher technologies with a unique vehicle design, and offers a game-changing economic viability as well as opening the door for routine low-cost and safe access to space. In order to validate the technology and accelerate the spaceplane development, POLARIS has been developing a series of scaled flight demonstrators.
