Abstract

We present the work made as part of the eHeroes project (eheroes.eu). The goal is to assess the doses that astronauts may receive during future journeys outside the Earth's magnetosphere. The final goal is to develop a data-driven tool able to predict doses on human tissues when specific conditions are defined, including thicknesses of the layers and the type of exposure, using data provided by some satellite. The first part of this work extesively uses the SPENVIS toolpackage in order to have a general view on results obtained from satistical models implemented within it. In particular, two future interplantery travels are taken into account: the journey to the Moon and to Mars, according to schedules planned by world-wide space agencies, predominantly NASA and ESA. Due to the lack of the knowledge on the final dimensions, shapes and materials, we decided to maintain the analysis as general as possible, by utilizing those tools provided by SPENVIS which considers pre-calculated coefficients and pre-configurated values. Finally, the DREADCode (www.spaceweather.eu/biological_effects) is developed in order to assess the doses with data input from different and more realistic sources, such as databases from ongoing missions, including ACE and GOES. By considering the same materials, which are predominantly aluminium-based alloys, thicknesses and surfaces, results from both tools are compared and discussed, in order to validate this approach and maintain a general and conservative computation.
