The solar wind plasma reaches supersonic speeds at a distance of a few solar radii from the Sun. From there, the solar wind carries its energy and momentum through interplanetary space, interacting with the magnetic fields, atmospheres, or surfaces of solar system bodies along the way.

These highly energetic cosmic rays have important space weather implications for exploration beyond our home planet. 1.2 FUNDAMENTAL PHYSICAL PROCESSES IN HELIOPHYSICS Heliophysics research provides an opportunity to explore fundamental plasma processes that also have important applications in laboratory plasma physics and for other astrophysical systems.

Important Solar and Planetary Winds for the solar wind, Earth's ionosphere wind into the magnetosphere, and stellar wind. Process of magnetic field of opposite direction annihilating each other to explosively convert magnetic energy into heat, radiation, and energetic Magnetic Reconnection particles.

Reconnection is the fundamental process responsible for solar flares and CMEs, for the dynamic coupling of the solar wind to the near-Earth space environment, and the ultimate driver for space weather. It is also thought to be responsible for many explosive phenomena in astrophysical plasma environments, such as acceleration of astrophysical jets, pulsars, and possibly gamma-ray bursts and cosmic ray acceleration (e.g., Lazarian et al., 2014; Zweibel and Yamada, 2009)

Such measurements help us better understand the shock structure and physics responsible for particle acceleration processes during varying solar wind conditions and space weather events. Understanding shock-driven acceleration processes from a basic physics perspective is essential for the better prediction of the energetic particle environment and for keeping technological societies safe at Earth, and eventually perhaps the Moon, Mars, and beyond.

This energy terminus forms the basis of "space weather" in Earth's geospace system with plasma-neutral interactions playing a critical role in spawning ITM variability that continues to limit predictability and plague our space assets. That one of the most complex examples of plasma-neutral interactions -- Earth's ITM -- is readily accessible to all modern research tools for investigation offers an extraordinary opportunity not only to advance understanding of Earth, but to expand knowledge of the nature of plasma-neutral interactions everywhere.
