Regions outside of Low Earth Orbit (LEO, altitudes above approximately 1000 km) are classified as "deep space", including Medium (MEO), geostationary orbit (GEO), well cislunar and lunar space. The deep space environment poses many challenges for human robotic exploration, stronger ionizing radiation fluxes, more extreme temperature variations, limited data downlink volume. With the growth rideshare hosted payload model aboard government commercial missions, developing capacity to design implement payloads other avionics this is increased importance decade. Utilizing one growing number opportunities offered by mission providers, National Central University (NCU) has been working on rapid development Taiwan's first scientific lander use, with launch HAKUTO-R Mission 2 (M2) from ispace, inc. scheduled not earlier than Q4 2024. This Deep Space Radiation Probe (DSRP) will provide measurements dose, dose rate, single event upset (SEU) rate during Earth-Moon transit, in orbit, surface. DSRP utilizes elements on-board computer (OBC) developed flight qualified NCU-developed IDEASSat 3U CubeSat 2021, was a student team, consultation experienced engineers team. In paper, we report objectives, concept operation, design, implementation project. We also describe steps taken facilitate parallel M2 lander, lessons learned implementation, qualification process. provided be beneficial future spacecraft avionics, crewed serve build at NCU.
