Exosuit Prototypic Knee: EPK

Resistive/aerobic exercises are invaluable countermeasures to musculoskeletal/sensorimotor/cognitive deconditioning resulting from spaceflight (i.e., microgravity). In preparation for human exploration to the moon and beyond, exercise countermeasures face new mass/volume constraints, rendering current on-orbit systems infeasible. Further, effective exercise systems are critical for maintaining crew performance/health levels necessary for Lunar extravehicular activities (EVAs) and transit. Exosuits are the pinnacle of wearable and adaptable technology set to provide a lightweight, compact, innovative solution to exploration-constrained exercise. However, reliable wearable kinematic sensors integrated with softgoods have not been demonstrated in (operational) spaceflight applications. To address this gap, the project team developed a prototype exosuit knee-joint, replete with relevant sensors for determination of joint angles, and corresponding laboratory testing bench to validate the exosuit sensing performance. This technology advancement is a pre-cursor to a more expansive multi-purpose exosuit concept that provides metrology, exercise, rehabilitation, and/or augmentation.

Crew Health and Performance Integrated Data Service Platform (CHP-IDSP): Project Updates

Future human exploration missions introduce a new paradigm as crews move further from the resupply and near real-time ground support typical of Low Earth Orbit missions today. Without immediate support from ground-based personnel, exploration crews will be more reliant on inflight data and technology to respond to emergencies and anomalies. Today, in-flight data is often siloed, unsynchronized, and largely inaccessible in real time. Many data sets require manual entry and/or data transfer between vehicles and the ground. These issues contribute to risks in supporting crew autonomy for future exploration missions. An integrated data services platform is needed to mitigate these risks by supporting a new generation of technologies and employing advanced analytical and predictive modeling techniques to enable crew autonomy for future exploration missions. The Crew Health and Performance Integrated Data System Platform (CHP-IDSP) project is laying a foundation for future in-flight informatics by providing a back-end architecture for collecting, storing, and integrating multiple sources of data generated by and around the crew. This cohesive integration point will streamline the management of CHP data (e.g., environmental, exercise, medical, sleep, performance, etc.) and facilitate situation awareness and decision support required by the crew and remote support of exploration missions. This presentation will describe the ongoing development effort of the path-to-flight CHP-IDSP software and the demonstration of its core capabilities. This includes a brief history of the project, the human-centered process used to identify data needs and workflows feeding the development of scenarios and requirements, and current subsystem development status. Current integrations, including the Chiron exploration electronic health record application, will be discussed. Future work includes collaboration with additional CHP domains and a flight technology demonstration.
