Water sublimator is a kind of thermal control device, which takes advantage of the high latent heat of water and can reject spacecraft waste heat by evaporating/sublimating water to vacuum environment. Thus, sublimator ...

A system level model that integrates the Wissler human thermal model with the geometry and functionality of a suit and PLSS has been developed and validated. The model permits prediction of a system level interaction, PLSS ...

The Z-1 is NASA's next generation spacesuit, designed for a range of possible missions with enhanced mobility for spacewalks both on planetary surfaces and in microgravity. Increased mobility was accomplished through ...

The current spacecraft technology to remove CO2 generated in manned missions uses mostly zeolite filters, which break down relatively easy; this has caused multiple problems over the last decades. The current solution has ...

In May 2015, neutron production from thick-target shielding experiments were conducted at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL). Secondary neutron yields produced by 0.4- and ...

The United States Atmosphere Revitalization life support system on the International Space Station (ISS) performs several services for the crew including oxygen generation, trace contaminant control, carbon dioxide (CO2) ...

Future NASA space telescopes and exploration missions require cryocooling of large areas such as optics, detector arrays, and cryogenic propellant tanks. One device that can potentially be used to provide closed-loop ...

Mars Ice House was the first place winner of NASA’s 2015 Centennial Challenge to 3D print a habitat for Mars using indigenous resources. Unlike most traditional design concepts making use of Martian regolith, Mars Ice House ...

All human habitat problems fall into three major categories – the environment, the habitat itself, and the occupants. By breaking these problems down into common themes and addressing them directly, we can build a common ...

Over the last year, NASA has continued to refine the understanding and prioritization of technology gaps that must be closed in order to achieve Evolvable Mars Campaign objectives. These efforts are reflected in updates ...
