Space Physics & Aeronomy (SPA)

The Space Physics and Aeronomy Section is united by its interest in the Sun, the heliosphere, and the upper atmospheres and magnetospheres of solar system planets and small bodies. 

Stop OMB From Erasing Federal Research!

AGU has an easy site to email or call your legislators to ask them to push back against the proposal.

Context: In late May, the Office of Management and Budget (OMB), released a proposed rule that could fundamentally change how scientific research is funded in the United States. If finalized as written, this rule would give political appointees veto power over peer review, allow the government to cancel active grants mid-project with minimal justification, ban entire categories of science from federal funding, and restrict researchers' ability to publish their work and attend scientific conferences. 

This is not a routine regulatory update. This is a restructuring of the foundational rules of U.S. science funding. If implemented, the consequences would be devastating. We need as many researchers as possible to speak up and submit substantive comments spelling out the impact this rule would have.

About SPA

The Space Physics and Aeronomy (SPA) Section is united by its interest in the Sun, the heliosphere (the region around the Sun that is permeated by the solar wind and the interplanetary magnetic field), and the upper atmospheres and magnetospheres of solar system planets and small bodies. To maintain the integrity of its scientific endeavors and to make participation in AGU activities more manageable, the Section is organized into three subsections:

  • Concerns of the Aeronomy (SA) subsection include the Earth’s ionosphere, thermosphere, and mesosphere, auroras and airglow, lightning, and planetary atmospheres and ionospheres.

  • Researchers affiliated with the Solar and Heliospheric physics (SH) subsection study the solar wind, coronal heating, flares, coronal mass ejections, magnetic reconnection, collisionless shocks, and helioseismology.

  • The Magnetospheric physics (SM) subsection’s focus is on geomagnetic storms, magnetospheric substorms, the magnetic fields and currents of the magnetosphere, the magnetopause, and the magnetospheres of planets and small bodies in the solar system.

All in the SPA Section share in the challenge to plan future space investigations that will lead to new discoveries. To generate excitement and understanding of space physics and aeronomy among the public, the SPA Section is involved in a number of educational initiatives.


Thank you to our sponsor, Lockheed-Martin, whose generosity enables many who would otherwise be excluded to attend the conference
