“…It contains all essential Mars Base Camp closed-loop life support system hardware as well as individual sleeping quarters and storage space for consumables. Using the methodology and consumption factors developed by NASA, 8 the Mars Base Camp is sized to accommodate 21 metric tons of consumables, and it includes an additional 1 metric ton of pressurized atmosphere in its fully assembled configuration. Consumables are distributed across the Mars Base Camp elements, including the habitat, avoiding single-fault vulnerabilities.…”

Mars Base Camp: An Architecture for Sending Humans to Mars

For nearly 70 years, sending humans to Mars has been the long term goal of many national space programs. Today, the consensus for sending humans to Mars appears stronger than ever before. With the amazing knowledge gained during the space shuttle and International Space Station programs, and with the Orion spacecraft and Space Launch System (SLS) launch vehicle completing development, NASA and its international and commercial partners are in a great position to lay out a plan for human Mars exploration and execute that plan. In May 2016, Lockheed Martin debuted the Mars Base Camp concept; a bold plan to transport scientist/astronauts from Earth to Mars within about a decade to answer fundamental science questions and prepare for a human landing. The key to achieving this vision is to capitalize on the major architecture elements already being developed by NASA, Orion and SLS, in an innovative architecture that focuses on crew safety and world-class science and exploration. Of course, Lockheed Martin is not the first to advocate for an orbital mission, but we believe that there are enormous advantages in an initial orbital mission, followed by landed missions in the subsequent opportunities.

“…), maintenance and spares, and packaging and overhead. Crew consumption rates were defined using International Space Station (ISS) historical usage and resupply rates in combination with data from the Advanced Life Support Baseline Values and Assumptions Document (BVAD) [18], the Human Integration Design Handbook (HIDH) [19], and Orion/Commercial Crew Development (CCDev) design values [20]. The rates represent current "best estimate" for future exploration systems, and may change as NASA refines mission designs.…”

This paper describes the recently developed point of departure design for a long duration, reusable Mars Transit Habitat, which was established during a 2016 NASA habitat design refinement activity supporting the definition of NASA's Evolvable Mars Campaign. As part of its development of sustainable human Mars mission concepts achievable in the 2030s, the Evolvable Mars Campaign has identified desired durations and mass/dimensional limits for long duration Mars habitat designs to enable the currently assumed solar electric and chemical transportation architectures. The Advanced Exploration Systems Mars Transit Habitat Refinement Activity brought together habitat subsystem design expertise from across NASA to develop an increased fidelity, consensus design for a transit habitat within these constraints. The resulting design and data (including a mass equipment list) contained in this paper are intended to help teams across the agency and potential commercial, academic, or international partners understand: 1) the current architecture/habitat guidelines and assumptions, 2) performance targets of such a habitat (particularly in mass, volume, and power), 3) the driving technology/capability developments and architectural solutions which are necessary for achieving these targets, and 4) mass reduction opportunities and research/design needs to inform the development of future research and proposals. Data presented includes: an overview of the habitat refinement activity including motivation and process when informative; full documentation of the baseline design guidelines and assumptions; detailed mass and volume breakdowns; a moderately detailed concept of operations; a preliminary interior layout design with rationale; a list of the required capabilities necessary to enable the desired mass; and identification of any worthwhile trades/analyses which could inform future habitat design efforts. As a whole, the data in the paper show that a transit habitat meeting the 43 metric tons launch mass/trans-Mars injection burn limits specified by the Evolvable Mars Campaign is achievable near the desired timeframe with moderate strategic investments including maintainable life support systems, repurposable structures and packaging, and lightweight exercise modalities. It also identifies operational and technological options to reduce this mass to less than 41 metric tons including staging of launch structure/packaging and alternate structural materials.

“…In addition, a packaging overhead of 1.5% by mass is applied to spare parts to account for foam and other packaging requirements for spares. 38 It is assumed that raw material can achieve 100 times greater volumetric density than traditional spares, 6 and therefore the packaging overhead applied to feedstock is 0.015%. This reduction in packaging overhead for feedstock also accounts for the fact that raw materials will likely be much more robust to launch loads than finished spares and will therefore require less foam and packaging materials for protection.…”
