In the summer of 2024, ESA announced a call for proposals for the construction of an analog moon habitat for its Astronaut Centre (EAC) in Cologne.
At the training center, there is a hall simulating a lunar landscape. The analog habitat is designed to accommodate astronauts for several days at a time, giving them the opportunity to train on Earth for living in a real lunar habitat. The interior is designed to replicate that of an actual habitat, and entry is only possible through an airlock.
