Abstract
The moon Io plays major role in the giant magnetosphere of Jupiter. At the same time, the magnetospheric particles and fields affect the moon. The impact of magnetospheric ions on Io’s atmosphere supplies clouds of escaping neutral atoms that populate a substantial fraction of its orbit. At the same time, ionization of atoms in the neutral cloud is the primary source of magnetospheric plasma. The stability of this feedback loop depends on the plasma-atmosphere interaction. The purpose of this review is to describe the physical processes that shape the space environment around Io and to show the impact from the planet Jupiter out into interplanetary space.
