A Design Study will be performed to assess the various design options, technical risks and cost effectiveness of this shelter concept. Also, detailed cost estimates will be developed for a subscale test article to demonstrate an ice dome/vault deployment. The study would produce an Ice Dome design concept and an Ice Dome Concept of Operations. The study would identify the primary technical risks, identify technology readiness and identify the external skillsets needed to build a subscale demonstrator for deployment studies. This study would also provide estimated cost and schedule as well as projected technical resources such as the size and mass of the inflatable structure that would be delivered to Mars.
