Kayhan Space aims to coordinate the increasingly crowded lower orbits, and Firehawk Aerospace has a new approach to rocketry that could lead to far more inexpensive launches. > We had Firehawk on stage (virtually) at Disrupt to compete in the Startup Battlefield, where they were among the finalists. The chief advance of the company is taking the concept of hybrid rockets and supercharging it with 3D-printed fuel. Instead of a reservoir of liquid, solid, or a combination of fuels, Firehawk prints the solid fuel with a “highly engineered internal structure” that makes it both more reliable and more powerful. It also simplifies the engine itself, which only has 12 parts.
