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 old 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 the present time, seminars are held on Fridays at noon 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.

Have an Idea for a Speaker?

The seminar organizer (currently Menelaos Sarantos, 301-286-2945, menelaos.sarantos-1@nasa.gov), is always appreciative of ideas for seminar speakers. Please contact him EARLY to avoid scheduling conflicts.

    Space & Solar Physics Meetings

    Year 2008

    Information for Speakers and Visitors

    Speakers interested in speaking at the Heliophysics Seminar are encouraged to contact the organizer, currently Menelaos Sarantos (301-286-2945, menelaos.sarantos-1@ nasa.gov). 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.

    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.
