They will participate in a daylong Tweetup program at Vandenberg Air Force Base in California on Thursday, Oct. 27 and view the launch of NASA’s NPP satellite, which is scheduled to lift off aboard a United Launch Alliance Delta II rocket between 2:48 and 2:57 a.m. PDT on Friday, Oct. 28.
The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) will collect critical data on long-term climate change and short-term weather conditions. With NPP, NASA continues gathering key data records initiated by the agency’s Earth Observing System satellites, monitoring changes in the atmosphere, oceans, vegetation, ice and solid Earth.
Tweetup participants were selected from more than 625 people who registered online. They will share their experiences with their followers through the social networking site Twitter. Attendees are coming from California, the District of Columbia, Illinois, Kansas, New York and Oregon.
Beginning at 9:30 a.m. PDT on Oct. 27, NASA will broadcast a portion of the Tweetup when attendees talk with NASA Astronaut Piers Sellers, the deputy director of the Sciences and Exploration Directorate at NASA’s Goddard Space Flight Center in Greenbelt, Md.; NPP Project Scientist Jim Gleason; NPP Systems Manager Janice Smith; NASA Launch Director Tim Dunn; and Scott Asbury, a senior program manager with Ball Aerospace & Technologies, Corp. in Boulder, Colo.
