Viper Science Operations: Lunar Dynamic Science Table and ‘Tracker’ Tool.

Introduction: The NASA VIPER lunar rover mission [1] presents a unique operational paradigm within the history of robotic spaceflight. The proximity of the Moon to the Earth and the terrain elements (surface characteristics, light/shadow dynamics, communication links) of the Lunar South Polar landing site create unprecedented operational conditions between these two planetary bodies. Apollo era lunar science and exploration included humans in situ to operate instruments and assimilate observational inputs
in real-time. Previous lunar orbital missions have worked to operational timescales, e.g., decisional
timelines and communication exchanges, that were weeks in duration. Mars rover missions have worked to
operational timescales, e.g., decisional timelines and communication exchanges between Mars and Earth,
that were hours, days, and weeks in length. In the case of the VIPER mission, our operational decisioning for
rover driving and instrument commanding will be compressed to minute-scale timeframes.

These operational conditions will directly impact the workflow and speed with which the VIPER Science
Team (VST) will be required to synthesize and analyze data and produce timely science-driven decisions
throughout surface mission operations [2]. The VST in the VIPER Mission Science Center (MSC) and the
Mission Operations Center (MOC) shall provide mission-enhancing scientific input to guide traverse
planning and drill site confirmation/selection throughout surface operations. Further, the VST input
will be of vital importance to the mission’s ability to maximize science return and to meet broader NASA
objectives for future lunar ISRU and exploration activities. Specifically, the VST in the MSC and MOC
will provide science-driven, consensus-based, timely input and decision-making to enhance mission
operations and align mission science return with broader Agency goals. They will enable the characterization of the distribution (lateral and vertical extent, concentration, variability), form (chemical/physical state of these reservoirs of lunar water and key isotopes), and context (e.g., accessibility/overburden, environment, soil mechanics, trafficability, and temperatures) of lunar polar volatiles and water content for the VIPER mission. Additionally, the MSC will be selecting or reconfirming the location and path towards and from the third drill site (Drill Site Charlie) within each Science Station [6].

To enable scientific decision-making within the operational paradigm of the VIPER lunar rover mission requires detailed articulation of the VST’s scientific objectives and goals, and the operationalization of these
objectives and goals through their association with specific data products, tasks, and decisional procedures. Further, defining and tracking scientific success metrics throughout surface operations will enable the VST to have a quantified understanding of the mission’s evolving ability to accomplish the stated scientific objectives and goals both during and after the mission. This abstract provides an overview of the methods and development activities towards defining, operationalizing, and tracking scientific objectives and goals throughout VIPER surface operations. Specifically, we focus on the VIPER Lunar Dynamic
Science Table (LDST) and the VIPER “Tracker” tool.
