A helmet with an integrated microphone includes a first portion to attach to a mating ring. The first portion is shaped to create a volume for a head of a wearer. The helmet also includes a second portion to attach to the mating ring. The first portion is entirely surrounded by the second portion without being in contact with the second portion and the second portion is farther from the volume than the first portion. One or more vibration sensors are attached to the first portion. The one or more vibration sensors output an electrical signal and the microphone is formed by the one or more vibration sensors and the first portion.

A facemask-mounted augmented reality (AR) display device is disclosed. In embodiments, the display device is hard-mounted to a breathing apparatus (e.g., oxygen mask, smoke mask) fitted to a user's nose and mouth behind a partially or fully covering external face shield. The AR display system includes display surfaces aligned with the eyes of the user and capable of providing the user with a forward field of view that moves with the user's head. The AR display system synthesizes streaming images with additional overlay sources (e.g., mission data, position data) to generate augmented reality content presented to the user within the field of view of the display surfaces.

Composite materials incorporated with shear thickening fluids (STF) are disclosed. The STF-composites are light weight and include high tenacity textiles that dissipate/absorb energy from impact forces and exhibit damage resistance and self-healing functionality. Also disclosed are articles comprising STF-composite materials, such as safety suits and extra-vehicular mobility units, which include STF-intercalated textiles and composites. Methods for Manufacturing STF-composites are also disclosed.

Provided are embodiments of a system for performing health monitoring. The system includes one or more wake-up modules configured to detect a condition, and one or more sensors operably coupled to the one or more wake-up modules, wherein the one or more sensors are configured to operate in a sleep mode and an active mode. The system also includes a spacesuit comprising one or more sensors, and a controller operably coupled to the one or more sensors, wherein the controller is configured to process measurement data from the one or more sensors. Also provided are embodiments of a method for performing health monitoring.

A spacesuit contaminant removal system includes at least one membrane separator and a liquid sorbent circuit. The at least one membrane separator is configured to receive a spent air stream from a ventilation system of a spacesuit and absorb a contaminant from the spent air stream into a liquid sorbent. The at least one membrane separator is configured to discharge a clean air stream to the ventilation system and discharge the contaminant in a contaminant stream to a space environment using a vacuum of the space environment. The liquid sorbent circuit is configured to circulate the liquid sorbent through the at least one membrane separator.

A covering includes an outer material, a plurality of conductive-fibers, and a fastening material. The outer material includes a front surface and a back surface and the conductive-fibers are disposed between the front surface and the back surface. The conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel and remove dust from the front surface of the outer material. The fastening material is coupled to the back surface of the outer material and facilitates releasably attaching the outer material to an article.
