ASME 2020 Conference on Smart Materials, Adaptive Structures and Intelligent Systems.
Future space exploration, such as the Artemis program, journeys to Mars, and future lander missions will require thermal control systems (TCSs) with the ability to adapt to a wide range of thermal loads due to vastly fluctuating external temperatures

Spacecraft designed for future missions must satisfy increasingly difficult thermal requirements. Crewed vehicles, in particular, must maintain a relatively constant temperature irrespective of external conditions; this is the role of the thermal con

As the United States plans to return astronauts to the moon and eventually to Mars, designing the most effective, efficient, and robust space suit life support system that will operate successfully in these dusty environments is vital. There is some

Flow regimes and bubble growth are observed in a pin-fin micro-scale heat exchanger with R-11 as the working fluid. The heat exchanger is machined in silicon and derived from a DNA micro-array consisting of 150 μm-square fins separated by 50 μm-squ

Spacecraft designed for missions beyond low earth orbit (LEO) face a difficult thermal control challenge, particularly in the case of crewed vehicles where the thermal control system (TCS) must maintain a relatively constant internal environment temp

As the field of smart structures matures, a variety of active components are being explored. One example is a morphing radiator that uses shape memory alloys (SMAs) to actuate, thereby altering its geometric effectiveness. This device exhibits a high

Human thermal modeling has considerable long-term utility to human space flight. Such models provide a tool to predict crew survivability in support of vehicle design and to evaluate crew response in untested space environments. It is to the benefit
