The Triennial Earth-Sun Summit (TESS) was held on May 20-24, 2018 in Leesburg, Virginia. 

It was a joint meeting of the Space Physics and Aeronomy Section of the American Geophysical Union (AGU) and the Solar Physics Division (SPD) of the American Astronomical Society.

TESS welcomed participation by the entire Heliophysics community, including all four traditional sub-disciplines devoted to studies of the Sun, Heliosphere, Magnetosphere, and Ionosphere-Thermosphere-Mesosphere. TESS not only promotes greater interaction and unity within Heliophysics, but also connections to astrophysics and planetary physics.

The scientific program included four interdisciplinary plenary sessions of interest across Heliophysics: Space Weather, Heliophysics Applied to Stellar-Planet Systems, Ion-Neutral Coupling Throughout the Heliophysical System, and Magnetic Reconnection in Space Plasmas.
