Spacecraft corresponding to the Pioneer, Vela, and Voyager have explored the interplanetary medium among the orbits of Mercury and Pluto. The insights derived from those missions were effectively utilized to magnetospheric, astro-solar, and cosmic ray physics. This publication is an outline of those insights, utilizing magnetohydrodynamic (MHD) flows because the framework for studying gadgets and tactics saw within the interplanetary medium. themes comprise quite a few forms of MHD shocks and interactions between them, tangential and rotational discontinuities, force-free box configurations, the formation of merged interplay areas linked to quite a few sorts of flows, the destruction of flows, the expansion of the Kelvin-Helmholtz instability and formation of a heliospheric vortex highway, the improvement of multifractal fluctuations on numerous scales, and the evolution of multifractal intermittent turbulence. scholars and researchers in astrophysics will worth the knowledge from those missions, which supply affirmation of many theoretical types of the interstellar medium.
