It's a dirty job, but two NASA spacecraft are ready to do it.
这个工作很脏，但两艘美宇航局航天器已准备好去做这事1-c^evBdXewI。
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.
8月23日，美宇航局计划发射两艘航天器到地球周围的辐射带h8F*Jts21#Gy^2Q。双辐射带风暴探测器将会调查被地球磁场吸引住的高能粒子s!IZcU_5Ze7kA0G。那些快速移动的质子和电子形成两个辐射带，被称为范艾伦辐射带，以物理学家詹姆士·范·艾伦的名字命名，他于1958年发现这个辐射带hmBDpNmAGTaqNszD5WJ。
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.

The Van Allen Belts are a nuisance to some spacecraft, and they could pose a hazard to future manned missions as well. But the Radiation Belt Storm Probes will call those harsh environs home. The spacecraft will fly through the belts for two years, measuring charged particles, plasma waves and magnetic fields in Earth's vicinity.

NASA hopes that the mission will help illuminate the complex physics of the stormy near-Earth environment. And, perhaps, help future spacecraft weather that storm.
