MAVEN: Exploring solar wind beyond Earth

As part of its goal to explore Mars’ upper atmosphere and its interaction with the Sun and the solar wind, MAVEN is exploring propagation of the solar wind and solar energetic particles (SEPs) beyond 1 Astronomical Unit [the distance between Earth and Sun] during its cruise to Mars. Solar wind density compressions from stream interactions and interplanetary coronal mass ejections (ICMEs) and SEP events are seen at the orbits of Earth and MAVEN… [More at link]
