Microgravity Research in the Space Shuttle Era
NASA dedicated over 20 shuttle missions to microgravity research as a primary payload, and many more missions carried microgravity research experiments as secondary payloads. The space agency’s microgravity research strived to increase understanding of the effects of gravity on biological, chemical, and physical systems. Living systems benefited as well. Cells, as they adapted to microgravity, ...

15 صفحه اولOn the shuttle glow the plasma alternative
It is shown that the anomalous glow observed in the recent space shuttle flights can be attributed to a combination of beam plasma discharge and critical ionization phenomena. While the shuttle velocity (~8 km s -x) is below the critical ionization velocity, which for oxygen is 12.7 km s -x, specular reflection of a small fraction (2-3%) of ambient ions forms an ion beam with velocity 16 km s -...
