Hurricane and Severe Storm Sentinel (HS3)

The Hurricane and Severe Storm Sentinel (HS3) mission overflies tropical storms and hurricanes using NASA's Global Hawk Unmanned Aircraft Systems (UAS) in the Northern Atlantic, Caribbean, and Gulf of Mexico. These flights will improve our understanding of the processes that lead to the development of intense hurricanes. The mission will take place for one-month periods during the 2012, 2013, and 2014 Atlantic Basin hurricane seasons. To learn more about HS3 visit
