ABSTRACT
Space weather for the extraterrestrial planets, just as at Earth, takes many different forms. This chapter covers a wide range of interplanetary and planetary space weather environments with particular stress on the characteristics of concern in the design of a reliable space system. Of particular importance to extraterrestrial space weather interactions are the planets’ magnetic fields. The magnetic field characteristics include dipole tilt, dipole offset, and magnetic moment of the magnetic field. A unique space weather feature of all bodies in the solar system is the way they interact with the solar wind. After radiation and thermal effects, dust is a major space weather hazard on the surfaces of Mars, moon, comets, and some asteroids of space systems. The dust and debris cloud associated with a comet, because of the possible hypervelocity impacts with a spacecraft, is another threat. Indeed, the dust and debris from a comet typically spread out along the comet’s trajectory giving rise to meteor streams.
