  • A resilience approach to the design of future Moon base power systems
    2020
    Co-Authors: Filippi Gianluca, Gillespie Drew, Wilson, Andrew Ross, Vasile Massimiliano
    Abstract:

    This paper proposes a novel approach to the design of complex engineering systems which maximise performance, and global system resilience. The approach is applied to the system level design of the power system for future Moon Bases. The power system is modelled as a network, where each node represents a specific power unit: energy storage, power distribution, power generation, power regulation. The performance and resilience of each power unit is defined by a mathematical model that depends on a set of design (control) and uncertain variables. The interrelationship among nodes is defined by functional links. The combination of multiple interconnected nodes defines the performance and resilience of the whole system. An optimisation procedure is then used to find the optimal values of the design parameters. The optimal solution maximises global system resilience where an optimal resilient solution is either robust, i.e. it is not subject to disruptive failures, or recovers from failures to achieve a functioning state, albeit different from the starting one, after a contingency occurs. The power system supports a Lunar base developed within the ESA-lab initiative, IGLUNA, led by the Swiss Space Centre. The power system, developed at the University of Strathclyde as part of the PowerHab project, is composed of nine interconnected elements: a hydrogen fuel cell energy storage system, a thermal mass storage system, a lithium-ion battery storage system, a constellation of solar power satellites (SPS) working in conjunction with a microwave wireless power transmission system, a reflecting satellite constellation and a ground-based solar power array. Distinct space and ground segments are identifiable, with orbit, AOCS and reflecting satellite nodes cooperating to provide optimal performance of the SPS constellation. The ground segment encompasses the ground-based solar array, energy storage systems, Lunar habitation module and the power transmission lines connecting these elements. Power generation is predominantly supplied by the ground-based array, with the SPS constellation and energy storage systems complementing this source; as well as providing redundancy and a reliable power supply during the Lunar night period

  • Moon Bases as Initial “Space Society” Trials: Utilizing Astrosociology to Make Space Settlements Livable
    AIP Conference Proceedings, 2007
    Co-Authors: Jim Pass
    Abstract:

    As we prepare to go back to the Moon on a permanent basis, it behooves us to take advantage of our return to the Moon by increasing our knowledge base so as to make all aspects of survival possible. The standard approach remains fixed on meeting the challenges related to power, physical habitat, and others associated with the physical environment and personal survival. While this traditional facet of space settlement must be addressed in a successful manner, the other set of variables to the equation for human survival in space receive little attention. In other words, we tend to focus so strongly on getting to a location and setting up a physical habitat that we overlook what it will require to survive in our new social world once the physical environment is functioning properly. We should take care now to begin formal consideration of the psychological, social, and cultural realities that will exist once we arrive. Plans starting with the very first Moon base should integrate research objectives that bo...

  • Future Mars Exploration Operational Simulation: Research Outcomes and Educational Benefit
    Space Operations: Contributions from the Global Community, 2017
    Co-Authors: Benjamin Morrell, Julie L. Read, Mauricio Coen, Austin Probe, Gregory Chamitoff, George H. James
    Abstract:

    A Mars Operational Simulation Exercise was performed by a class of senior undergraduates and graduates to educate the students both on how human spaceflight operations are currently done and on how these operations might evolve in the future. Four structured, operational “Tiger Teams” worked on a Design Reference Infrastructure for a hypothetical Mars exploration scenario that included novel aspects such as Mars Moon Bases, small vehicles for in-system transportation, and substantial teleoperation. The teams then developed operational plans to address an emergency scenario. Through extending the principles of human spaceflight to a future Mars exploration scenario, a number of key lessons were learned on how future Mars mission operations should be run. In particular it was found that there needs to be a tight feedback loop between technological development and operations, and that a paradigm shift is necessary in the way operations are performed to be applicable to a Mars system. A second, updated iteration of the exercise supported these findings. The exercises identified that similar, in-depth simulations can be powerful tools to drive current mission and system design for Mars exploration. This chapter presents the details on the Mars Operational Simulation Exercise and the key findings that resulted.

  • Space design
    Personal and Ubiquitous Computing, 2011
    Co-Authors: Irene Lia Schlacht, Henrik Birke
    Abstract:

    Space stations, Moon Bases and Mars Bases are artificial habitats intended to support human life in extreme conditions. Their purpose is to pursue human progress and to gain knowledge and experience of the environment surrounding our planet. This research focuses on visual investigation in order to improve interface design in space habitat interiors. The subject of this article is why the visual interface (as created through color, light, and artistic and natural visual inputs) is to be considered as fundamental for user reliability in isolated space habitats. The aim is to improve the quality of living conditions in today’s International Space Station (ISS) and in future long-term missions to Mars but also in more immediate prospects such as Space tourism. Taking into account experiences from an internship in Thales Alenia Space, ESA Space Habitat Workshops and PhD studies on Space Habitability, the authors’ purpose is to enhance the development of concepts and projects on spacecraft visual interface with an ergonomic approach. The main topics in this paper are the following: (1) Visual needs in Space habitat interiors. (2) Sight modification in Space environment. (3) Design: Project Requirements for Outer Space. (4) Moon Base Design.
