Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

The geoarchaeology of planetary exploration: new approaches to space heritage preservation
On 21 May 2015, the United States passed the ‘Commercial Space Launch Competitiveness Act’, also known as the SPACE Act, encouraging a competitive commercial space exploration industry and effectively ushering a new space race, or even space age. Unlike the former space age of the 1950s–1970s which was characterized by intense competition between the ...

Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Space travel in a high-altitude environment: One more step in human BioSpaceForming
BACKGROUND: Currently, space programs use sea-level pressures (760 mmHg) and normoxia (21% oxygen fraction) in space capsules. When astronauts need to go for a spacewalk, the pressure has to be reduced to 1/3 that of sea level (240 mmHg).

Aerospace medicine required controlled terrestrial models to investigate influences of altered atmosphere conditions, such as hypoxia, on human health and performance. These models could potentially be expanded to encompass disease conditions or treatment targets regulated through hypoxia or hypercapnia.
