Artemis-I - Development and Testing of Radiation Mitigation Strategies for Crewed Missions
The Space Radiation Analysis Group (SRAG) at Johnson Space Center developed a variety of radiation monitoring devices, space weather tools and crew exposure tracking products that were successfully tested during Artemis-I. These include vehicle area monitoring using the Hybrid Electronic Radiation Assessor (HERA) as the prime environment monitor for flight operations on Orion; Crew Active Dosimeter (CAD) as a precursor for crew worn dosimeters and tested during Artemis-I Science Payloads research (e.g., Commander Moonikin Campos, BioExpt-1 and the international collaboration Matroshka AstroRad Radiation Experiment - MARE); space weather Scoreboard interface hosting prediction model outputs (collaboration with Moon to Mars Space Weather Analysis Office and Community Coordinated Modeling Center at Goddard Space Flight Center); Acute Radiation Risk Tool (ARRT) predicting biological impacts during an energetic solar particle event using as input onboard radiation instrumentation; Mission operation tools to monitor real-time telemetered data and allow efficient 24/7 console operations support in preparation for the first crewed lunar mission (including daily communications with the Flight Control Team (FCT), internal and external collaborators). The current paper will present an overview of the Artemis-I radiation protection technology and tools, radiation measurements and data using the International Space Station (ISS) as testbed for these technologies, and preliminary Artemis-I data.
