Headline Details: Project Mission Name: Additively Manufactured Deployable Radiator with Oscillating Heat Pipes Mission Description: This educational project consists of students (CubeSat Lab) at California Polytechnic State University, San Luis Obispo, and California State University, Los Angeles. The primary objective of the AMDROHPSat mission is to perform an on-orbit technology demonstration of the Additively Manufactured Deployable Radiator with Oscillating Heat Pipes (AMDROHP). This 3U CubeSat experiment seeks to validate the ability of a novel, student-integrated thermal system to reject up to 50W of heat in Low Earth Orbit. The mission’s secondary objective is to facilitate learn by doing and self-training for the student team. Students are learning about satellites and space communication by designing, building, testing, integrating, and operating a 3U CubeSat. After the launch and early operations phase has concluded, payload deployment will occur and the digipeater will be enabled. AMDROHP payload experimentation and digipeater operation will continue until loss of communications occurs as AMDROHPSat reenters Earth’s atmosphere. This phase is expected to take approximately 1 year. More info at https://www.polysat.org/ Proposong a UHF downlink using 9k6 GFSK. Planning launch from KSC on NG25 NET Dec 2026 to the ISS.
