The Department of Defense, specifically the Navy, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program for the development of a "Reentry Plasma Onset and Emergence Sensor." This sensor aims to accurately determine the onset and emergence from plasma environments that hinder telemetry signal transmission during ballistic reentry, thereby enhancing data collection and analysis for flight tests. The successful development of this sensor is critical for improving communication capabilities in high-temperature environments, which are essential for both crewed space missions and future hypersonic aircraft operations. Interested parties should note that the solicitation is currently closed, with the next opportunity expected to open on May 15, 2024, and applications due by June 12, 2024.
