Phase Change Materials are very good candidates to smooth temperature variations of units which undergo thermal cycling dissipations or external cycling thermal loads. They can also be used to damped fast but short thermal ...

The National Aeronautics and Space Administration’s (NASA) crewed spacecraft use containers to store waste derived from food, water, and other supplies. The trash bags occupy a large volume and present a significant ...

Resources are extremely limited in spacecraft, and oxygen consumed for breathing also needs regeneration. In the system using the current Sabatier reaction (CO2 + 4H2 → CH4 + 2H2O), O2 can only be collected up to about 50% ...

This paper outlines a design methodology of adapting launch vehicle payload fairing geometries into pressurized single or multi-element space stations. Large volume, low budget space stations can be achieved through ...

Environmental Control and Life Support Systems (ECLSS) for a crewed lunar base differ from those for Space Stations in Low Earth Orbit (LEO), mainly due to the increased distance, and therefore more expensive resupply ...

Today’s astronaut corps represents a wide range of various anthropometric dimensions. Accommodating this wide range of anthropometry and protecting for size variations in future crews, makes spacesuit sizing and fit a ...

Supportability will be a significantly greater driver of cost and risk for future deep-space crewed missions than it has been in the past. Spares requirements and maintenance risk mitigation in particular present an ...

The Membrane Microgravity Air Conditioner (MMAC) is a microgravity compatible condensing heat exchanger for removal of particulates, humidity, and heat from air, with production of clean condensate, leading to possible ...

Over the past several years, the University of Maryland has been developing technologies for in-situ additive manufacturing of spacesuits based on AX-5-type hard suits. Past work covered technologies tested for fabrication ...

The Exploration Portable Life Support System (xPLSS) maintains life support for a suited crew member during Extravehicular Activity (EVA). The thermal and pneumatic/hydraulic interactions within the xPLSS have been modeled ...
