The briefing will be held at NASA Headquarters at 300 E St. SW in Washington and air live on NASA Television and the agency's website. IRIS is scheduled to launch June 26 from Vandenberg Air Force Base in California. IRIS is a NASA Small Explorer Mission to observe how solar material moves, gathers energy, and heats up as it travels through a little-understood region in the sun's lower atmosphere. This interface region between the sun's photosphere and corona powers its dynamic million-degree atmosphere and drives the solar wind. The region is the origin of most of the ultraviolet solar emission that impacts the near-Earth space environment and Earth's climate. The panelists for the briefing are: -- Jeffrey Newmark, IRIS program scientist, NASA Headquarters, Washington -- Alan Title, IRIS principal investigator, Lockheed Martin's Advanced Technology Center, Palo Alto, Calif. -- Gary Kushner, IRIS program manager, Lockheed Martin's Advanced Technology Center, Palo Alto, Calif. -- John Marmie, IRIS assistant project manager, NASA's Ames Research Center, Moffett Field, Calif.
