In preparation for the challenges of modern and future Lunar missions, NASA has decided to leverage augmented reality technology to aid astronauts to accomplish their lunar assignments and field work. This manuscript describes the work that students have created to meet the NASA SUITS Design Challenge, which is part of the Artemis Student Challenges. In order to develop a system designed to aid users through complex and possibly dangerous tasks, we propose the Augmented Reality Guidance and Operations System (ARGOS) which utilizes the Magic Leap One Augmented Reality Headset (ML1) to simulate the spacesuit of an astronaut on an EVA. Using the ML1, ARGOS presents a minimal, yet effective user interface designed to display vital information, provide instructions, and reduce the cognitive load for the user. We accomplish these tasks through the introduction of 3 main elements in our system: Voice Commands/Interaction, Remote Control Application, and the ARGOS-specific Operations Control, Translation, and Visual Interface Assistant, also known as OCTaVIA. The goal of ARGOS is to create a system that will ensure a user's ability to complete the given task with the utmost safety and efficiency, despite any communication failures that may occur. Lunar missions present a unique and dangerous set of challenges, and with the updated design of ARGOS, astronauts will have an available and usable system built specifically to help reduce cognitive load, aid completion of tasks, and increase safety, with the support of a cloud-like data processing infrastructure that lives on the network itself. This manuscript describes ARGOS as a training platform as well as a testbed for systems that will support human exploration. We also report preliminary tests of its effectiveness in terms of usability and efficiency. Lastly, we briefly describe how this system has become a significant platform for student engagement in a higher education context.
To create a safer operational environment during EVAs, we propose OCTaVIA (Operations Control, Translation, and Visual Interface Assistance), a modular and robust system that incorporates industry-standard technologies used in cloud architectures. The main features include distributed data storage, processing and redundancy, a communications infrastructure designed for disaster recovery, computational load balancing, localization services, and passive safety mechanisms. We utilize a testbed composed of several Raspberry Pi and Jetson Nano devices placed on stationary posts within the EVA workspace, which operate as nodes in a Kubernetes infrastructure, a system that automatically deploys, manages, and scales containerized applications. The system offers distributed processing and communications through the Raspberry Pi devices, GPU-intensive computing devices with Jetson Nanos, and LiDAR-enhanced visual technology to support remote as well as automated monitoring of EVA worksites. OCTaVIA is part of ARGOS, a larger solution presented at ICES 2021 aimed at creating an information and communications management system that utilizes augmented reality to let astronauts interact with mission personnel and assets.
