A rare bird has been flying over the Great Lakes
recently, and it isn't migrating or searching for prey.
This hawkeyed species is a Learjet aircraft outfitted with an advanced
imaging system. Engineers at NASA's Glenn
in Cleveland modified the plane to help the
National Oceanic and Atmospheric Administration (NOAA) monitor algae in western
Lake Erie and Lake Huron's Saginaw
Bay. The Glenn team began
its latest round of flights in August.
