MARS • Moon Phobos Electric Charging 17.12.23 VIDEO: The interaction of the solar wind with the Martian moon Phobos creates a complex electrical environment that could impact future exploration. (full credits below) • Mars has two moons, Phobos and Deimos. Both are small, airless bodies with irregular shapes. Because they lack protective atmospheres and magnetospheres, Phobos and Deimos are directly exposed to the solar wind for part of their orbits. The solar wind is a stream of electrically ch
