DARPA has issued a Request for Information to explore the feasibility of large bio-mechanical space structures. The agency envisions creating massive structures over 500 meters long, potentially for purposes like collecting orbital debris, tethers for space elevators, or wings for commercial space stations. This approach could alleviate challenges related to transporting materials from Earth by allowing for biological growth in microgravity. By using biological growth mechanisms combined with structural poles, these creations could serve various functional roles in space.
The agency is looking for structures more than 500 meters long, which could serve various purposes such as orbital debris collection or self-assembled wings for commercial stations.
Growing a lengthy structure in microgravity might minimize the logistical challenges of transporting building materials from Earth, offering a new method for constructing large-scale structures in space.
