The Department of Defense, specifically the Space Rapid Capabilities Office (SpRCO) under the Department of the Air Force, is seeking information from potential vendors regarding low-cost, low Size, Weight, and Power (SWaP) sensors for space-based Space Domain Awareness (SDA). The objective of this Request for Information (RFI) is to identify mature technologies suitable for a Direct to Phase II (D2P2) Small Business Innovation Research (SBIR) project, aimed at enhancing space domain awareness capabilities amidst increasing competition in space. Interested parties are encouraged to submit concise responses, limited to four pages, by emailing Jennifer Wilterdink at jennifer.wilterdink.1@spaceforce.mil, with the subject line "RFI Response: Low-Cost, Low SWaP SDA Sensors." Questions regarding the RFI will be accepted until May 30, 2025, and it is important to note that this RFI is for informational purposes only and does not constitute a solicitation.
