About us
Our mission is to pioneer a new era of space transportation by flying to space and back like an aircraft — taking off and landing at airports, and reusing our spaceplanes for hundreds of missions. We combine unprecedented cost efficiency with unique flexibility and safety, enabling breakthrough advances in both space transportation and hypersonic flight. This vision is currently pursued by almost
80 employees
every day.
