Environments of Terrestrial Planets Under the Young Sun: Seeds of Biomolecules
9-13 April, 2018 – NASA Goddard Space Flight Center, Greenbelt, MD, USA

Hosted by the Sellers Exoplanet Environments Collaboration, this symposium is a major international interdisciplinary conference in the emerging area of astrobiology covering astrophysical, physico-chemical, atmospheric and geological aspects of environments of early terrestrial planets with a focus on the impacts of the young Sun’s space weather on the precursors of life. 

The central objective of the Symposium is to unify and coordinate these efforts to understand, and characterize heliophysical, magnetospheric, ionospheric, climate and their interaction with geological environments on the early Earth, Mars and Venus and their impacts on the initiation of prebiotic chemistry.

The official web site for the symposium is available at https://science.gsfc.nasa.gov/600/seec/Events/Environments_of_Terrestrial_Planets_Under_the_Young_Sun.htmlPlease register and submit your abstract (at no cost) at https://asd.gsfc.nasa.gov/conferences/seec/2018_Symposium/ . 

Please contact Prof. Vladimir Airapetian at NASA/GSFC and American University at vladimir.airapetian at nasa.gov

TESS Session: Abstract Reminder and General Contributions Session

From: Holly Gilbert (holly.r.gilbert at nasa.gov)

This is a reminder that the TESS abstract submission deadline is February 20, 2018. This meeting will function as the 2018 meeting of the SPD.  

Please note there is a "session" called General Contributions intended for contributed submissions of any nature that do not fit into a designated special session.  We understand that many contributions are not appropriate for one of the special sessions.  This applies to the majority of SPD contributions. These should be submitted as General. The organizing committee will construct cohesive, theme- based sessions out of these contributions, including both oral and poster sessions.  This is the conventional approach during stand- alone SPD meetings

Please note you do not have to be an AGU member to register for the meeting or to submit an abstract. You may need to create an account on the server for this purpose.

The Triennial Sun Summit (TESS) will be held on May 20-24, 2018 at the Lansdowne Resort and Spa in Leesburg, VA (http://connect.agu.org/tess2018/home). TESS is 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 Session: Sources for Suprathermal Ions

From: Yuan-Kuen Ko, George C. Ho, Nariaki Nitta (yuan-kuen.ko at nrl.navy.mil)

We invite contributions to the session “Sources for Suprathermal Ions” (https://agu.confex.com/agu/2018tess/preliminaryview.cgi/Session40387)
at The Triennial Earth–Sun Summit (TESS) that will be held on May 20-24, 2018 at the Lansdowne Resort and Spa in Leesburg, VA, USA (https://connect.agu.org/tess2018/home). 

Abstract submission deadline: February 20, 2018

Session Description:
Suprathermal ions (ions of a few times the solar wind plasma energy up to 100s of keV per charge) are known to play a significant role as the seed population in the acceleration to high energy particles by coronal mass ejection (CME) shocks. In the quest for a reliable prediction of the properties of large solar energetic particle (SEP) events, one crucial element is a quantitative understanding of how the suprathermal particles are produced and distributed in the solar corona and the solar wind, especially as a sustained source. Another crucial element is a quantitative understanding of how the variation in the suprathermal seed population contributes to the variation in SEP properties. This session invites contributions from theories, models and observations that aim toward this aspect of research.

Confirmed invited speakers:
Martin Lee (University of New Hampshire)
Richard Mewaldt (Caltech)
Elena Provornikova (George Mason University)

Origin, evolution, and Earth impact of energetic particles from solar, magnetospheric and galactic sources

Session Description: 
The radiation effects of energetic particles have not only severe implications for interplanetary manned space missions but can also cause fatal damage of satellites due to charging or radiation damage of electronic components. Although the intensity of galactic cosmic rays that have their origin outside the heliosphere varies by less than an order of magnitude over the solar cycle flux GCRs form the most energetic radiation component. Less energetic are solar energetic particles. Energetic electrons in the outer radiation belts have been known to increase by several orders of magnitude for sustained periods of time and cause spacecraft damage via deep dielectric discharge. Together with energetic particles of magnetospheric origin like those in the dynamic radiation belts these particles have their impact on the Earth’ environment. We invite contributions that present modeling as well as observational results on the origin, evolution and impact of these radiation components.
