Co-Chairs: Ramesh B. Malla, Ph.D., F. ASCE, University of Connecticut, Storrs, CT; Melissa Sampson, Ph.D., Ball Aerospace, Boulder, CO; Alexander Jablonski, Ph.D., P.Eng, Canadian Space Agency, Ottawa, Canada; and Gerald (Jerry) B. Sanders, NASA Johnson Space Center, Houston, TX
There have been increased activities and interests in space activities, especially lunar and Martian exploration by the public and private sectors alike. Many national and international agencies and space industry are currently involved in the planned lunar missions. The recent United States Space Policy Directive 1 directs NASA to focus on lunar exploration with a new human return to the Moon and then manned missions to Mars. These efforts will involve both robotic and human missions. The recent landing of the Chinese lunar surface probe Chang’e-4 on the far side of the Moon has opened up a new chapter in lunar exploration with plans by several space actors for humans to follow in the late 2020’s.
As the world’s space community prepares to return to the Moon with humans, this time to stay, explore and then settle elsewhere in the Solar System on a long term basis, it is imperative that we continue to support the development of qualified engineering, construction and architecture concepts and guidance for these developments. On Earth, multiple new spaceports have been constructed with modernized methods and operations, providing new insights into enhanced operational efficiencies, This symposium deals with innovative concepts, methods, designs, research, development, and applications related to all aspects of human space exploration, architecture, engineering and construction, including facilities in orbit and on planetary surfaces such as the Moon, Mars, moons of Mars and asteroids, as well as terrestrial spaceports.
Special Session Topics
Innovative Engineering and Construction on the Moon and Mars Utilizing and Harnessing Indigenous Geo-Environmental Resources
Session Organizers: Ramesh B. Malla, Ph.D., F. ASCE, University of Connecticut, Storrs, CT and Gerald (Jerry) B. Sanders, NASA Johnson Space Center, Houston, TX
It has been long realized that long term sustainable human settlements on the Moon and Mars are only possible if the local geological and environmental resources can be utilized substantially for day to day operation. Several studies can be found dealing with the use of lunar and Martian regolith for various purposes, including habitat building material, protection against radiation and extreme temperatures, extracting oxygen, and mining. However, in-depth and exhaustive studies on the use of regolith for engineering and construction is still lacking. Moreover, new innovative methodologies for design, engineering and construction need to be developed that exclusively harness and utilize indigenous geological and environmental resources. For example, the extremely hot and cold environment on the lunar surface may someday pave a path for new engineering innovation and technologies. It might even be possible to tap the everlasting radiation on the lunar surface for certain engineering and construction purpose. How about the low gravity and vacuum that exist on the moon? These may be leveraged to come up with new and innovative design and construction technologies. This session presents papers on various aspects of innovative engineering, construction, development, and operations utilizing and harnessing local geo & environmental resources available on the Moon and Mars.
Technical Requirements for Lunar Systems
Session Organizers: Alexander M. Jablonski, Ph.D., Canadian Space Agency, Ottawa, Canada; and Kin F. Man, Ph.D., NASA Jet Propulsion Laboratory (JPL), California Institute of Technology, Pasadena, CA
The Moon is Earth’s nearest celestial body. It has one of the most challenging natural environments in our solar system. They include: high vacuum, high diurnal temperature variations, super-cold temperatures in the permanently-shadowed regions, abundance of very fine and abrasive lunar dusts, a reduced gravity field (1/6 of Earth’s g), the danger of moonquakes (as high as almost 3.5 on the Richter scale), the danger of meteoroid and micrometeoroid impacts, and the duration of the lunar day. Detailed knowledge of the lunar environmental conditions is crucial for defining the technical requirements for lunar systems and structures. This session focuses on the technical requirements for lunar missions, particularly focusing on lunar system requirements associated with long surface operations, in addition to the technical requirements associated with the other typical mission phases for lunar missions: ground processing, storage, and transportation; launch; cruise; orbit insertion; and EDL (Entry, Descent and Landing). This session also covers the impact of the lunar environmental conditions on ground-based qualification testing requirements and test methodologies to survive the expected long operational life on the lunar surface, at both assembly/subsystem and system levels.
Tensegrity Structural Systems for Moon and Mars Space Applications
Session Organizer: Robert Skelton, Ph.D., Texas A & M University, College Station, TX
Tensegrity concepts have proved to be the minimal mass solution for many fundamental problems in Engineering and provide the possibility of designing strong yet lightweight and robust structures often with the integration of sensors and actuators. Robots made of tensegrity are lightweight yet strong compared to robot by conventional construction. Tensegrity structures have thus been proposed for planetary landing and exploration, as well as systems for space habitats and related functions. The session will deal with concepts and novel applications of tensegrity systems for space exploration including on the Moon and Mars. Papers are solicited on topics dealing with the wide-range of applications of tensegrity systems, including flexible structures, planet landers, deployable space antennas, robots, space debris collector, lunar and Martian rovers, habitats, and others.

Robotics Development for Lunar and Martian Constructions
Session Organizer: Mustafa Alsaleh, Ph.D., Caterpillar, Inc., Peoria, IL
The recent literature review has clearly shown the great deal of focus on robotics development in variety of applications, including construction repair, and maintenance in the harsh space environments, in orbit and on the lunar and Martian surfaces. Robotics design, development or building is not trivial and often goes through many iterations to get it right, especially in the harsh, extreme and previously untested conditions that exist in space. Leveraging simulations should make this process easier to deal with as the simulation makes it possible to cut down the number of design, build and test iterations. Simulation can enable new applications and allow testing before building any physical model. Once design is finalized, less physical testing can be used to confirm the intended functioning of the robots. This special session deals with robotics development and application for space engineering and construction, especially on lunar and Martian environment. Papers dealing with various topics in these areas are solicited.

Session Organizers: Robert P. Mueller, NASA Kennedy Space Center, FL; and James T. Barrett, Turner Construction, New York, NY
In recent years there has been significant activity in the construction of terrestrial spaceports to support the launch and landing of space transportation vehicles, both in the USA and worldwide. The impetus for this renaissance in spaceport construction has been the entry of new actors into the space launch and landing business. Commercial entities and government entities are introducing new transportation systems with increased life cycle efficiencies, incorporating the lessons learned from the past 60 years of spaceport operations. Reusability and reduced cost have become new drivers in the spaceport design and operations. Small launch vehicles for small satellite constellations need efficient and routine launching capabilities. The military is seeking a rapid response capability. Spaceports are also expanding beyond the Earth’s surface to the Moon and Mars, where spaceports must also be constructed to support reusability and in-situ re-fueling. Lessons learned from spaceport terrestrial construction can be applied to these new extreme environments with innovative engineering and operations. Papers are sought that will communicate the construction project sequences, experiences and lessons learned from recent spaceport construction and which will identify technology advancements achieved and also those that are likely to be required in the future.
