Sample Answer & Audio Transcript

It's a dirty job, but two NASA spacecraft are ready to do it. On August 23rd, NASA plans to launch two spacecraft into the radiation belts around Earth. The twin Radiation Belt Storm Probes will investigate high-energy particles held in place by Earth's magnetic field. Those fast-moving protons and electrons form two bands known as the Van Allen radiation belts, after physicist James Van Allen, who discovered them in 1958. The two NASA probes will study how the belts formed and what makes them swell up from time to time. The outer radiation belt, in particular, can change quickly in response to the sun's outbursts of charged particles, also known as solar storms.
