NASA/GSFC Heliophysics Science Division Seminar

Heliophysics Science Division Seminar

About the Seminar

The Heliophysics Science Division conducts weekly science seminars. Heliophysics is a new division in the Science Mission Directorate at NASA's Goddard Space Flight Center. It has been formed out of portions of the former Laboratory for Extraterrestrial Physics (LEP, 690), Laboratory for Astronomy and Solar Physics (680), and Space Science Data Operations Office (630). It was previously known as the Laboratory for Solar and Space Physics (LSSP). At present, seminars are held on Fridays at 1:00pm in the Conference Room (Room 183) in Building 21 at Goddard. The topics cover the interests of the Laboratory, including astrochemistry, interplanetary physics, solar physics, planetary systems, planetary magnetospheres, and electrodynamics.

Year 2013

Information for Speakers and Visitors

Speakers interested in speaking at the Heliophysics Seminar are encouraged to contact the organizer, currently Nicki Viall, 301-286-4054, The duration of the seminar is typically one hour, with questions asked during and after the seminar. The audience is usually diverse, including scientists with interests ranging throughout the heliosphere. Visit the Heliophysics Science Division Home Page for a more complete summary of interests

As most of you know, in the last few years it has become harder to get visitors from outside of NASA on center, and the number of days needed to get unescorted access is subject to change. Thus we ask that if a visitor wants to attend a talk and needs a non-escort badge they should request one as soon as possible. We will help to the best of our ability, but can't make any guarantees.
