NASA's known for space flight, but next week one of its airplanes is going to start buzzing low over central Maryland, dipping down to 1,000 feet off the ground at times.
The series of overflights beginning Monday are part of a monthlong mission to sample the region's air pollution. Federal, state and university scientists hope the data gathered will help them design new air monitoring satellites and ground stations.
For more on the flights and the region's air quality, read my colleague Frank Roylance's story in baltimoresun.com
