Teleconference panelists are:
- Jon Morse, director, Astrophysics Division, NASA Headquarters in Washington
- Julie McEnery, Fermi project scientist, NASA's Goddard Space Flight Center in Greenbelt, Md.
- Doug Finkbeiner, associate professor of astronomy, Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass.
