Toward understanding the nature and structure of our Heliospheric shield

Session ID#: 158239

Session Description:
The heliosphere is an immense shield that protects the solar system from harsh, galactic radiation. The radiation that enters the heliosphere affects life on Earth as well as human space exploration. Galactic cosmic rays are the dominant source of radiation and principal hazard affecting space missions within our solar system. To understand the heliosphere’s shielding properties, we need to understand its structure and large-scale dynamics. Although a fortunate confluence of missions such as Voyager, IBEX, and Casini has provided the scientific community with a treasury of heliospheric data, fundamental features remain unknown. Knowledge gaps include the basic shape of the heliosphere, the extent of its tail, the flow pattern and the width of the heliosheath, and the filtration of galactic cosmic rays in the heliosheath. In this session, we solicit observational and modeling studies that advance our understanding of the global nature and shape of the heliosphere, pickup ion evolution from the termination shock to the heliotail, turbulence in the heliosheath, and the modulation and filtration of galactic cosmic rays through the heliosphere.
