WASHINGTON — NASA will hold a news briefing on Wednesday, Oct. 12, at 1 p.m. EDT, on the agency’s next Earth-observing satellite mission, the National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP), scheduled to launch on Oct. 27 from Vandenberg Air Force Base, Calif.

NPP is the first of a new generation of satellites that will observe many facets of our changing Earth. The mission will collect critical data to improve our understanding of long-term climate change and short-term weather conditions. With NPP, NASA continues many key data records of Earth’s atmosphere, oceans, vegetation, and ice initiated by the agency’s Earth Observing System satellites.

The panelists are:

– Andrew Carson, NPP program executive, NASA Headquarters
– Ken Schwer, NPP project manager, Goddard Space Flight Center, Greenbelt, Md.
– Dr. Jim Gleason, NPP project scientist, Goddard Space Flight Center
– Dr. Louis Uccellini, director, National Oceanic and Atmospheric
Administration’s National Centers for Environmental Prediction, Camp Springs, Md.

The briefing will be held in the James E. Webb Auditorium at NASA Headquarters, 300 E St. SW, Washington. Reporters unable to attend in person may ask questions from participating NASA centers or by telephone. To participate by phone, reporters must contact Dwayne Brown at 202-358-1726 or dwayne.c.brown@nasa.gov by 9 a.m. on Oct. 12.
