The Liulin-SET device developed at the Space Research Institute of the Bulgarian Academy of Sciences will fly into space on February 19. Head of the research team is Prof. Tsvetan Dachev. This is the 23rd device developed in the Solar-Earth Physics section of the institute to operate in space. It was commissioned by the U.S. company Space Environment Technology and is part of the ARMAS (Automated Radiation Measurements for Aerospace Safety) module of the space station.
After successfully passing the tests, Liulin-SET is soon to start measuring cosmic radiation and after a period of 6 months to a year, ARMAS and the Liulin-SET will be brought back to Earth for analysis of accumulated data. The dose of cosmic radiation is a key parameter for the health of astronauts aboard the ISS, the Bulgarian Academy of Sciences, say.
