Silicate ultrahigh vacuum frictional and adhesional behavior as related to lunar surface
Solar light, solar wind, differences between temperatures of the lunar surface, solar photosphere, and deep space, as well as noticeable changes of surface temperature in the absence of atmosphere provide opportunities for energy production and storage on the Moon using generators ranging from solar panels and thermocouples to devices using phase transitions or magnetism. There are multiple and diverse possibilities for energy generation and storage. Compositions of the relevant materials can be compared to abundances of chemical elements in lunar regolith.

Differential reflectivity concept use in determining scattered electromagnetic radiation from lunar surface
Ultrahigh vacuum adhesion of single crystal silicates - relation to lunar surface properties
This presentation summarizes the contents of the uncrewed lunar surface operations and support activities paper. It outlines the functions, features, and capabilities that support sustained human and robotic surface operations. It summarizes the complexities associated with the development and operation of autonomous systems and discusses a simulation tool for integrated surface operations planning.
The stated goals of the 2004 Vision for Space Exploration focus on establishing a human presence throughout the solar system beginning with the establishment of a permanent human presence on the Moon. However, the precise objectives to be accomplished on the lunar surface and the optimal system architecture to achieve those objectives have been a topic of much debate since the inception of the Constellation Program. There are two basic styles of system architectures being traded at the Programmatic level: a traditional large outpost that would focus on techniques for survival off our home planet and a greater depth of exploration within one area, or a mobile approach- akin to a series of nomadic camps- that would allow greater breadth of exploration opportunities. The traditional outpost philosophy is well within the understood pressure garment design space with respect to developing interfaces and operational life cycle models. The mobile outpost, however, combines many unknowns with respect to pressure garment performance and reliability that could dramatically affect the cost and schedule risks associated with the Constellation space suit system. This paper provides an overview of the concepts being traded for a mobile architecture from the operations and hardware implementation perspective, describes the primary risks to the Constellation pressure garment associated with each of the concepts, and summarizes the approach necessary to quantify the pressure garment design risks to enable the Constellation Program to make informed decisions when deciding on an overall lunar surface systems architecture.
