Exposure of astronauts to space radiation will be one of the most important risks for future exploration class missions to the Moon and Mars. In addition to the use of personal dosimeters and the real-time monitoring of ambient radiation dose rates on spacecraft and planetary surfaces, high level data products from multi-spacecraft measurements will be also used in mission planning to estimate the dose (fore- and nowcasting) and thus reducing, and mitigating health risks to astronauts. HUN-REN Centre for Energy Research is involved both in space weather (source) and space dosimetry (effects) activities, including development of instruments and measurement techniques, and modelling. The first generation of the TRITEL 3D silicon detector dosimeter system, developed in the HUN-REN Centre for Energy Research, was used several times on board the ISS between 2012 and 2020. Following lessons learned, a second generation of the TRITEL instruments will continue data provision starting from 2027. One will be combined with a space weather radiation telescope (RADTEL) on board the Earth Return Orbiter for the Mars Sample Return Mission (Space Dosimetry System payload), the other will be part of the very first internal experiment on the Gateway space station in Lunar orbit by the European Space Agency (ESA), the Internal Dosimeter Array (IDA). In the frame of ESA’s AURORA mission, a constellation of satellites will study the Aurora Borealis. The RadMag instrument suite that will be on board comprises RADTEL telescopes supplemented with fluxgate magnetometers. A significant overlap in the operation of the above instruments is expected. 

The aim of the work is to develop methods for analysis of multi-spacecraft measurements with silicon detector telescopes developed by the HUN-REN Centre for Energy Research and integrated on different spacecraft platforms, with focus on solar proton events, and to utilize the measurement data for refining existing space radiation (galactic cosmic rays and solar proton event) models and for provision of higher level dosimetry data products (proxys) to facilitate mission planning. To achieve this goal, Monte Carlo calculations and analysis of publicly available radiation measurements with silicon detector systems in space will be also performed. Professional support will be provided to the Candidate by the Space Research Department of the HUN-REN Centre for Energy Research.
