NASA Readies New Type of Earth-Observing Satellite for Launch
NASA is planning an Oct. 27 launch of the first Earth-observing satellite to measure both global climate changes and key weather variables. The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) is the first mission designed to collect critical data to improve weather forecasts in the short-term and increase our understanding of long-term climate change. NPP continues observations of Earth from space that NASA has pioneered for more than 40 years. NPP's five science instruments, including four new state-of-the-art sensors, will provide scientists with data to extend more than 30 key long-term datasets. These records, which range from the ozone layer and land cover to atmospheric temperatures and ice cover, are critical for global change science. "NPP's observations of a wide range of interconnected Earth properties and processes will give us the big picture of how our planet changes," said Jim
