Preliminary concept for lunar exploration tracking and data acquisition and data processing systems
The NASA Office of Exploration is evaluating potential scenarios for an ambitious and complex mission to the moon. This paper sumarizes the initial system engineering analyses being performed to identify the communications, data processing, and navigational support required by these case studies. A feasible option for providing tracking and data acquisition using technology available in the 1990s is described.
Rationale and requirements for lunar exploration
The moon has had a complex and geologically fascinating history. It is a natural laboratory in which to study planetary processes and is readily accessible, only 2.5 days away. The moon is the only planetary object from which there are samples of known geologic context, and its history is understood well enough to permit the posing and answering of sophisticated scientific questions. The moon also preserves information about the earth's early history and cratering record, and about the sun's history. To retrieve all this information, it is necessary to return to the moon and study it from orbit, establish surface geophysical networks, obtain reconnaissance samples, and perform field work. These ventures will require development of interesting technological systems, such as a robotic field geologist, automated roving vehicles (both pressurized for humans and unpressurized for robotic devices), a host of sampling tools, automated sample-return spacecraft, and all of the associated navigation, communication, and power systems.

Lithologic Diversity in Lunar Regolith: Lessons for Future Lunar Exploration Strategies with Application to South Pole-Aitken Basin
Diversity of rock fragments in individual regolith samples from Apollo sites and inferred regolith stratigraphy from large craters and basins in the South Pole-Aitken region are used to assess the value of a single-point sample from the SPA basin. Additional information is contained in the original extended abstract.
Robotic Assistance for Human Planetary and Lunar Exploration
Human exploration of space will need robotic assistance in many areas. The type and functionality of such robots needs to be more clearly defined as we resume human missions to the moon and begin human missions to Mars. This paper will identify possible robotic assistants, including their control modes, workplaces, and physical attributes. Current JSC human-robot interaction projects are described, and lessons learned from extensive field tests are given. Future scenario considerations are then detailed. Earth-based testing of varied robotic assistants will provide a means of defining what capabilities are needed for future exploration.
