Deep Space Radiation Probe 是一個由IDEASSat 任務延伸而來的酬載，由於發生在IDEASSat衛星上SEL (Single Event Latchup)導致IDEASSat任務壽命不如預期，於是便設計了Deep Space Radiation Probe 以了解太空環境中輻射對衛星所產生的危害。由於Deep Space Radiation Probe搭乘日本民間登月廠商 ispace 的Hakuto-R Mission2 所經過的太空環境不管是對結構，熱控還是輻射都比低軌道還要更加嚴苛，因此需要更加注意相關的設計。Hakuto-R Mission2是由日本的Ispace研發的衛星，其軌道會經過月球，最終登陸在月球之上，而Deep Space Radiation Probe會被固定在Hakuto-R外側以量測相關的輻射數據。本論文主要會介紹與討論到如何滿足Deep Space Radiation Probe 的結構以及在熱控需求上的設計，使其能再不管是在軌道上或是月球上都能正常運作。由於DSRP是固定在Hakuto-R外殼的外側，而非內側，因此在不管是振動對結構的破壞，還是環境中的極高、極低溫，都要面臨非常嚴苛的挑戰。本文將會介紹如何設計才能克服嚴苛的環境條件，以及相關模擬還有實際的測試驗證結果，還有過程中的經驗學習與討論。Deep Space Radiation Probe的研發會為未來不管是小型衛星還是其他各種會上太空的酬載提供更加了解太空輻射對儀器危害，以避免可能的危險性，提高任務壽命。;Deep Space Radiation Probe(DSRP) is a payload which come up idea from the IDEASSat mission. Since the SEL (Single Event Latchup) caused the IDEASSat mission life to be less than expected, so that we design DSRP to understand the hazards of radiation on satellites in the space environment. Since the Deep Space Radiation Probe is going to be rideshare on the Hakato-R Mission2 which is developed from ispace, the space environment it passes through is even more severe than low-earth orbit in terms of structure, thermal control, and radiation, and thus requires more attention to the related design. Hakato-R Mission2 trans-lunar injection orbit will pass by the Moon and eventually land on the Moon, and the DSRP will be fixed on the out-plane of Hakato-R, in order to measure the radiation data. This paper will introduce and discusse how to design the structure and the thermal control systems of DSRP, so that the DSRP can function properly both in orbit and on the Moon surface. Since the DSRP is fixed to the out-plane of the Hakato-R Mission2 instead of the inside, it has to face very severe challenges of vibration damage to the structure, as well as the extremely high and low temperatures in the space environment. In this paper, we will also introduce the design which can overcome the severe environmental conditions, and the results of the related simulation and the environment testing, as well as the learning and discussion in this process. The development of the Deep Space Radiation Probe will provide a better understanding of the hazards of space radiation to the future payloads and satellites, which can avoid possible dangers and to increase the mission life.
