With the EDEN ISS greenhouse located in the otherworldly environment of Antarctica, DLR was able to replicate as closely as possible the conditions of a long-term space mission. The research laboratory not only served to test vegetable cultivation for future crewed space missions to the Moon and Mars. It also enabled researchers to explore the possibility of food production in climatically unfavourable areas such as deserts and arctic regions in the future. After five years on the seventh continent, Antarctica, amongst ice, cold and the polar night, the greenhouse is back at the DLR Institute of Space Systems in Bremen. There, it is being refitted and made available for the training of future lunar astronauts.
