Inflatable freeform domes for potential Mars habitats. Since the atmospheric pressure on Mars is 100 times lower than Earth’s, the interior must be pressurized. This motivates the use of inflatable structures that can be efficiently erected from flat configurations, offering the additional benefits of low weight and compact storage. Our deployable auxetics offer a rich design shape space, so we can optimize the shape of the freeform domes to match interior space objectives.
