Spacecraft Flying in Polar Orbit

Caption

MEME-X's two spacecraft would fly in a polar orbit to find out how plasma escapes from Earth's ionosphere, which lies 50 to 620 miles above the surface, into the protective magnetosphere that shields the planet from potentially harmful solar wind and other space weather, and then out into space.
