Analog Astronaut Training Center is a private company, which accelerates human spaceflight scientific studies. AATC was created by former European Space Agency professionals: engineer and scientist. In 2018, the company established a laboratory to simulate space environment for scientific experiments focused on space biology and medicine. The facility is located in Rzepiennik, South of Poland. It specialises in operational trainings for scientists, engineers, space enthusiasts and future astronaut candidates. Beside scientific projects, co-supervision of engineer- master and doctoral theses, AATC organizes rocket workshops, stratospheric missions and scientific lunar and martian analog simulations. In 2021 the company has reached 32 successfully organized analog simulations, what positions Poland on the top in Europe considering the number of organized expeditions. Most of trained analog astronauts continue their career in the space sector. AATC helps them to develop and grow by publishing their work on international platforms, by sharing precious international contacts and collaborations and involving them in multiple ongoing space projects.
