2012 NRC Solar/Space Physics Decadal Report

Unread post by Dotini » Wed Aug 29, 2012 6:32 pm

This is a report that lays out the last 10 years discoveries and the next 10 years agenda in solar and space physics. It's just about 100% concerning plasma, magnetic fields, electric fields, interdisciplinary connected systems and sciences. So it's evident a revolution is underway, and the good side is winning. Please get a grip and bite your tongue when you see the term reconnection. Really, it'll be okay!

Here is a link that will enable you to browse/skim/download the 454 page 2012 NRC Solar/Space Physics Decadal report.

For convenience, the broad discipline of solar and space physics, often referred to as heliophysics, is divided into the following three areas, each of which is described in much greater detail in separate chapters (8 though 10) of the report:

~ Sun and heliosphere (SH) - covers the physics of the outer regions of the sun and its expansion through interplanetary space;

~ Solar wind-magnetosphere interactions (SWMI) - deals with the interaction of the solar wind with magnetized bodies (principally Earth and other planets) and the resulting coupling to their underlying ionosphere or planetary surface;

~ Atmosphere-ionosphere-magnetosphere interactions (AIMI)
- concerns the dynamics of planetary ionospheres due to solar, magnetospheric and atmospheric drivers and coupling.

As discussed in table 2.1, each of these panels organized their work around 4 scientific challenges.


TABLE 2.1 Solar and Space Physics Decadal Challenges

The Sun and the Heliosphere

SH-1 Understand how the sun generates the quasi-cyclical magnetic field that extends throughout the heliosphere.

SH-2 Determine how the sun's magnetism creates its hot, dynamic atmosphere.

SH-3 Determine how magnetic energy is stored and explosively released and how the resultant disturbances propagate through the heliosphere.

SH-4 Discover how the sun interacts with the local interstellar medium.

Solar Wind - Magnetosphere Interaction

SWMI-1 Establish how magnetic reconnection is triggered and how it evolves to drive mass, momentum and energy transport.

SWMI-2 Identify the mechanism that controls the production, loss, and energization of energetic particles in the magnetosphere.

SWMI-3 Determine how coupling and feedback between the magnetosphere, ionosphere, and thermosphere govern the dynamics of the coupled system in response to the variable solar wind.

SWMI-4 Critically advance the physical understanding of magnetospheres and their coupling to ionspheres and thermospheres by comparing models against observation from different magnetospheric systems.

Atmosphere - Ionosphere - Magnetosphere Interactions

AIMI-1 Understand how the ionosphere-thermosphere system responds to and regulates magnetospheric forcing over global, regional and local scales.

AIMI-2 Understand the plasma-neutral coupling processes that give rise to local, regional and global-scale structures and dynamics in the AIM system.

AIMI-3 Understand how forcing from the lower atmosphere via tidal, planetary, and gravity waves influences the ionosphere and thermosphere.

AIMI-4 Determine and identify the causes for long-term (multi-decadal) changes in the AIM system.

PS: When you delve into this, (there is much detail), you'll find NASA is loaded to the gills with plasma physicists!

PS1: For those that prefer, here's a 70 minute video presentation of the subject report. One of the two chief authors/presenters is a plasma physicist.
