HabitatOS is the first open-source operating system for use in human spaceflight habitats. The system supports customizable time-delayed communication for Moon and Mars simulations. With a responsive HTML interface, it can be used on any device such as desktops, mobile smartphones, tablets, TV screens, and smartwatches. It has an open and documented API for the development of new features and an easy-to-use pluggable add-on structure to build experiments around.
