NASA astronaut Andre Douglas wears AR (Augmented Reality) display technology during an advanced technology run in the San Francisco Volcanic Field in Northern Arizona on May 21, 2024. The monocular lens consists of a pico-projector and waveguide optical element to focus an image for crew to see their real world overlaid with digital information. These unique near-eye form factors may be used to improve the usability and minimally impact the complex biomechanics of working in a pressurized suit environment. Credit: NASA/Josh Valcarcel
