The Radioactivity of Space - With Frances Staples

Explore 60 years of scientific discovery surrounding radiation hazards in space in this lecture by Frances Staples. Delve into the history of space radiation research, starting with the successful launch of Explorer 1 and the unexpected measurements that led to the discovery of the Van Allen radiation belts. Learn about the structure of Earth's magnetic field, the sources of radiation in space, and the effects of geomagnetic storms. Discover how waves can accelerate particles in space and the recent findings from missions like SAMPEX and the Van Allen Probes. Gain insights into the complex interactions between the solar wind and Earth's magnetosphere, and understand the importance of space weather forecasting for protecting technology and infrastructure. From early experiments like Operation Argus to modern observations of the third radiation belt, trace the evolution of our understanding of space radiation and its implications for space exploration and satellite technology.
