A thermal management system includes a space structure, a feed water container, a water feed line, a pump, and a filter device. The space structure includes a heat source connected with a fluid loop for conveying a working fluid through the heat source to regulate temperature and a sublimator connected with the fluid loop to receive the working fluid. The sublimator has a porous surface. The water feed line is connected with the container and the sublimator. The pump is located in the feed water line and is operable to move the feed water from the container to the sublimator. The sublimator is operable to cool the working fluid using the porous surface. The filter device is located in the water feed line between the pump and the feed water container. The filter device includes an adsorbent bed to remove organic compounds.

Disclosed are curved electrochromic devices comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus. Also disclosed are processes for manufacturing the disclosed bubble visors.

Systems and methods to remove dust from an extravehicular mobility unit (EMU) worn by an astronaut in a deep space environment involve one or more ionic shower units installed external to an interior volume of a facility. Each ionic shower unit releases positively charged ions and negatively charged ions in a specified direction to neutralize the dust and generate neutralized dust. The interior volume of the facility is defined by an interior hatch that is separated from an exterior hatch by an airlock. One or more collection units is installed external to the interior volume. Each collection unit traps the neutralized dust to prevent the dust from entering the interior volume.

A helmet with an integrated speaker 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 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 transducers are attached to the first portion. The one or more transducers receive an electrical signal representing an audio signal and the speaker is formed by the one or more transducers and the first portion.
