The dynamic life support system (LSS) simulation software Virtual Habitat (V-HAB) has been under development at the Technische Universit ̈at Mu ̈nchen since 2006. The MATLAB -based V-HAB software suite dynamically simulates habitat life support sys- tems and their interaction with a detailed human model, as well as the external environment of the habitat. This paper presents the current development status of V-HAB. One of the main areas of work on V-HAB over the past year has been the inclusion of reliability data on the component level to enable the reliability analysis of LSS architectures. Also, parts of the core infrastructure were refactored to provide additional functionality. Within the biological module several new models were developed including microbial trickle filter for waste processing and models of rodents and arthropods. Also the plant model was enhanced to support greenhouse optimization studies. V-SUIT, the spin-off from V-HAB with the capability of simulating space suit portable life support systems (PLSS), has also matured over the past year. A solver for computing liquid flows was implemented. Also, several models of technologies used in the LSS were implemented to depict those components in more detail. The paper describes each of the areas mentioned above in greater detail, presents se- lected simulation results and concludes with an outlook onto the path ahead for V-HAB.
