The scheduled October 1 launch of NASA’s CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellites will be previewed at a news media briefing at 1 p.m. EDT, Thursday, September 15. The briefing is in NASA’s Webb Auditorium, 300 E St. SW, Washington.

CloudSat and CALIPSO will provide new perspectives on Earth’s clouds and aerosols. The satellites will answer questions about how they form, evolve, affect water supply, climate, weather and air quality. The satellites will be launched into an orbit, where they will fly just 15 seconds apart as members of NASA’s “A-Train,” a constellation of several Earth-observing satellites.

Briefing participants:

Dr. Steve Volz, NASA CloudSat-CALIPSO program executive, Science Mission Directorate (SMD), Washington Dr. Don Anderson, NASA CloudSat-CALIPSO program scientist, SMD Dr. David Winker, CALIPSO principal investigator, Langley Research Center, Hampton, Va. Dr. Graeme Stephens, CloudSat principal investigator, Colorado State University, Fort Collins, Colo.
