The Future Lunar Exploration Habitat (FLEXHab) will accommodate further scientific activities and experiments. Located outside of the ESA-DLR LUNA analogue facility, it will provide a direct connection to the testbed surface. An airlock ingress and egress setup will allow users to test and prepare for lunar spacewalks known as Extravehicular Activities (EVA), and to assess aspects of dust protection as well as suit and tool cleaning and maintenance.
