A helmet for a space suit includes a transparent section located at a front of the helmet. The transparent section includes a base glass having an inner surface located on an inside of the helmet and an outer surface located on an outside of the helmet, and a photochromatic transition glass. All or a portion, less than all, of the base glass is overlapped by the photochromatic transition glass. The helmet also includes a non-transparent section located at a back of the helmet.

A system to perform multi-stage cleaning of material from a space suit worn by an astronaut in a deep space environment includes one or more discharge units installed external to an interior volume of a facility in the deep space environment. Each of the one or more discharge units releases one or more substances. The one or more substances includes water or air and the interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch leading to the deep space environment by an airlock. One or more collection units installed external to the interior volume. Each collection unit traps released material that is released from a space suit based on the multi-stage cleaning to prevent the released material from entering the interior volume.

A pulsed oxygen delivery system is disclosed for a closed breathing environment, which includes a source of gaseous oxygen, a phase dilution type oronasal dispensing mask worn by a user in a closed breathing environment defined by a pressure suit, and a pulse control module for delivering a timed and metered bolus of oxygen from the source of gaseous oxygen to the oronasal dispensing mask upon inhalation by the user.

Modular armor for a hard upper torso (HUT) of an atmospheric suit that maintains a specific atmosphere within the suit includes a first outer layer including a first surface and a second surface opposite the first surface and a second outer layer including a first surface and a second surface opposite the first surface. A core is sandwiched between the first surface of the first outer layer and the first surface of the second outer layer. The armor is fabricated such that the second surface of the first outer layer is conformally affixed to the HUT.
