The term "Design Reference Mission 3.0" refers to a NASA study on a human exploration architecture for Mars. The study was performed by the NASA Mars Exploration Team at the NASA's Johnson Space Center (JSC) in the 1990s. Personnel representing several NASA field centers formulated a “Reference Mission” addressing human exploration of Mars. The plan describes the first human missions to Mars with concept of operations and technologies to be used as a first cut at an architecture. The architecture for the Mars Reference Mission builds on previous work, principally on the work of the Synthesis Group (1991) and Zubrin’s (1991) concepts for the use of propellants derived from the martian atmosphere. The primary purpose of the Reference Mission was to stimulate further thought and development of alternative approaches which can improve effectiveness, reduce risks, and reduce cost. Improvements can be made at several levels; for example, in the architectural, mission, and system levels.
The Mars Exploration Study Project was undertaken to establish a vision for the human exploration of Mars that would serve as a mechanism for understanding the programmatic and technical requirements that would be placed on existing and planned Agency [NASA] programs. In August 1992, the first workshop of the Mars Study Team held at the Lunar and Planetary Institute in Houston, Texas, addressed the “whys” of Mars exploration to provide the top-level requirements from which the Mars exploration program could be built (Duke and Budden 1992). The study team of personnel from NASA field centers used these inputs to construct the Reference Mission, and then translated the inputs into a set of goals and objectives. Ground rules and assumptions were agreed upon and reflect the lessons learned from previous study efforts. From this work, a mission and a set of systems were developed.
As the report of the Reference Mission Version 3.0 states: "From the work of the original Reference Mission (Version 1.0), the strategy for the human exploration of Mars has evolved from its original form to one of reduced system mass, use of a smaller, more reasonable launch vehicle, and use of more current technology. The steps which have been taken by the Exploration Team are motivated by the need to reduce the mass of the payload delivery flights, as well as the overall mission cost, without introducing additional mission risk. By eliminating the need for a large heavy-lift launch vehicle and deleting the redundant habitat delivery flight in Version 3.0 , two launches from the Earth were eliminated. The net result is a current Version 3.0 Reference Mission which requires an injected mass of approximately one-half that of the 1993/94 Reference Mission."
