This paper describes a design process for an extravehicular system suitable for accomplishing a set of specific missions in an interplanetary environment. This process is based upon project management, system engineering, and strategic management concepts. The process is a sequential set of incremental actions which build upon prior activities in order to reach a design solution. Each process step considers a specific goal, environmental influences, as well as the general mission. The paper first addresses the overall mission in order to produce a set of functional requirements for each of the major mission components. The extravehicular system is then developed via a similar process to satisfy those functional requirements. The end result of this process is an extravehicular system specifically tailored to accomplish the mission.

This paper describes a design process used to develop an extravehicular system suitable for accomplishing a set of specific missions in a Mars environment. The paper first identifies specific candidate geological and operational missions that require direct extravehicular activity action. The tools and procedures necessary to accomplish these missions are identified. The missions are analyzed in order to produce a set of functional and design requirements for the extravehicular system. A preliminary design of an extravehicular system specifically tailored to accomplish the identified missions is presented.
