\nDynamics Explorer 1<\/a> and Dynamics Explorer 2<\/a> were high- and low-altitude spacecraft, respectively, intended to<\/p>\n

investigate the strong interactive processes coupling the hot, tenuous, convecting plasmas of the magnetosphere and the cooler, denser plasmas and gases corotating in the earth’s ionosphere, upper atmosphere, and plasmasphere. <\/p><\/blockquote>\n

\nThe spacecrafts’ orbits were such that one made high-altitude observations while the other made low-altitude observations, which could be compared to better understand atmospheric dynamics and the interaction of our atmosphere with charged particles from the Sun. Mission operations ended in 1991.<\/p>\n\"Facebook\"<\/a>\"twitter\"<\/a>\"pinterest\"<\/a>\"linkedin\"<\/a>\"mail\"<\/a>by <\/span>\"feather\"<\/a>","protected":false},"excerpt":{"rendered":"
