The Habitat Design Workshop 2005 has been conceived by the MoonMars Working Group with the support of the European Space Agency (ESA –ESATEC) that hosted the workshop from 2 nd to 10 th April 2005 in The Netherlands. The MoonMars Working Group is an undergraduate and postgraduate led programme of interactive, international and trans-disciplinary projects, which aims to get undergraduates and young professional actively involved in Moon and Mars projects, workshop and other related events. The Habitat Design Workshop 2005 is the first workshop focused on interdisciplinary interaction in the develop of human habitat for Moon, Mars and Phobos (satellite of Mars). Thirty students and young professionals from disciplines such as engineering, medicine, physics, architecture and industrial design were selected to participate at this workshop. This paper presents the methods, process and outcomes of the design workshop. We conclude with evaluating this type of interactive workshop and its impact on developing the skills needed for the next generation space workforce.
