Extravehicular Activity Mission System Software (EMSS) - Enabling Human Planetary Exploration Data Within The Broader Planetary Data Ecosystem

The planetary science community is once again on the verge of generating, capturing and analyzing human planetary exploration data, this time via the Artemis program. Artemis missions will involve robotic missions in addition to human extravehicular activity (EVA) where crew will be generating scientific data [1]. Present-day robotic mission data expectations for data archiving involves ingesting data into the Planetary Data System (PDS), but how might PDS be leveraged/adapted/ready (or not) for human spaceflight mission data, particularly EVA data that includes non-scientific data that provides important context to the scientific data gathered on the lunar surface? This question has broader implications than what this abstract can answer, but we wanted to pose the question to 1) get conversations started and 2) highlight how operations software data handling could play a role in overall data curation.

Horizontally Integrated Informatics to Support Science Operations in Human Spaceflight

Many systems will be designed and developed for the Artemis program. A subset of these systems will be relevant to scientific activities conducted during the program, but it is important to consider that these scientific activities will be conducted within the context of the larger program. Thinking about the program data holistically, and deliberately structuring its data products in a way that preserves the data’s mission context will enable new opportunities for real-time science support, and long-term analysis of the mission and its data for generations to come (see [1] for an example). Here, we show that horizontally integrated mission data products are valuable by describing the SSERVI RISE2 field program. Temporally contextualized data introduces relationships that do not need to be predefined. One field that greatly benefits from freeform relationship building between disparate datasets is anomaly investigation, where investigators need to follow lines of evidence that may not be a priori apparent. Building relationships between data enables accident investigators to react faster to time-sensitive incidents during EVA operation and other critical human spaceflight activities. Another advantage is the long-term data preservation that enables unplanned or yet-to-be conceived applications or study of this data many years in the future. As Artemis activities become more defined, having a horizontally integrated data management plan will be paramount to ensuring successful mission context is captured for generations to come.

Scientific Physical and Operations Characterization (SPOC): Studying Scientists in the Wild to Inform Human Planetary Exploration Operations

The objective of the Scientific Physical and Operational Characterization (SPOC) project is to build an evidence-based description of terrestrial field science to inform the operational, physical, and tool requirements for planetary exploration extravehicular activities (xEVAs). EVAs of the future, including Artemis 2024 and beyond, intend to promote scientific productivity (e.g., LEAG science goals)[1]; however, no clear, objective pathway currently exists to enable this goal, particularly with respect to the desired increase in autonomy imparted to future astronauts. The SPOC project applies expertise in the fields of cognitive systems engineering [2-5], biomechanics, wearable sensors [6-8] and hardware/software to more targetly address these issues. In doing so, a terrestrial fieldwork ground-truth can be established that will benefit human and robotic exploration of other planetary surfaces.
