Birmingham, U.K.—Drawing on three spacecraft—U.S., Japanese, and Russian—that are now flying through Earth's magnetosphere, scientists are planning a 3- to 5-month campaign of coordinated observations. By making simultaneous measurements at different points in this vast region of trapped particles, they hope to unravel how it captures energy from the solar wind and funnels it toward Earth. The campaign is scheduled for this winter, when the orbits of all three satellites will place them in favorable positions.
