The Department of Defense, through the Defense Advanced Research Projects Agency (DARPA), is seeking innovative responses to a Request for Information (RFI) focused on the development of large bio-mechanical space structures, such as space elevators and debris remediation nets. The objective is to explore the feasibility of utilizing advances in biological engineering and metabolic processes to create structures exceeding 500 meters, which could significantly reduce payload requirements from Earth. This initiative is critical for advancing in-situ grown structures that offer structural rigidity and controlled growth directionality, thereby enhancing capabilities in space exploration and utilization. Interested parties must submit their responses by March 27, 2025, in a specified format, and can direct inquiries to Dr. Michael "Orbit" Nayak at DARPA via email at DARPA-SN-25-51@darpa.mil.
