The Defense Advanced Research Projects Agency has selected 14 companies for a seven-month capability study that seeks to develop technology concepts to advance an integrated, multiservice commercial lunar infrastructure. Under the 10-Year Lunar Architecture Capability Study, the companies will collaborate to design systems-level platforms spanning multiple lunar services, including lunar power; communications, navigation and timing; mining and commercial in-situ resource utilization; construction and robotics; and transit, mobility and logistics, DARPA said Tuesday.
