Thomas Berger is a physicist and heads the Biophysics working group in the Radiation Biology department at the DLR Institute of Aerospace Medicine. Together with his colleagues, he develops, builds and flies radiation measuring instruments into space.
Berger is the Principal Investigator of DLR's MARE project, in which the measuring bodies Helga and Zohar will fly once around the Moon in 2022 on the first uncrewed flight of the Orion spacecraft as part of NASA's Artemis I mission. The experiment serves to measure the radiation exposure on the female body. For the first time, the Orion flight will collect gender-specific measurement data on space radiation outside the ISS orbit, which is needed to develop a radiation protection vest.
