The Department of Defense (DOD) is seeking proposals for the topic "Reentry Plasma Onset and Emergence Sensor" as part of their SBIR 24.2 Annual solicitation. The Navy branch is specifically interested in this technology. The objective is to develop a sensor that can determine the onset and emergence of a plasma environment during ballistic reentry, where telemetry signals are blocked. The sensor should be able to characterize the environment in real-time, communicate with existing telemetry infrastructure, and survive space and ballistic reentry environments. The final product should be capable of withstanding various environmental conditions. Phase I involves demonstrating the capability to characterize a plasma environment and communicate with an external controller. Phase II focuses on building and evaluating a prototype sensor, preferably in a relevant plasma environment. Phase III aims to integrate the sensor into a Navy flight test body and enhance the transmission of data during test events. The technology has potential applications in crewed space missions and future hypersonic aircraft. The solicitation is open until June 12, 2024, and more details can be found on the DOD SBIR website.
