NASA will fly two unmanned aircraft over Atlantic hurricanes this summer. Join us for this live Google+ Hangout featuring a NASA pilot and one of the two Global Hawk aircraft in its hangar at NASA's Dryden Flight Research Center in California. The Hurricane and Severe Storm Sentinel, or HS3, mission is a five-year project that first took to the field in 2012 from NASA's Wallops Flight Facility, Wallops Island, Va. HS3 is investigating the roles of the large-scale environment and storm-scale internal processes in hurricane formation and intensity change in the Atlantic basin. HS3 scientists will use two NASA Global Hawks during the campaign, one with instruments measuring the environment around a tropical cyclone and the other with instruments looking into the storms. Participants in the event will hear about the 2012 mission and preparations underway at Wallops for this summer's flights. The HS3 lead scientist will explain how NASA will peer into hurricanes. And a Global Hawk pilot will discuss remote flying over tropical cyclones. Participants for the Google+ Hangout are: * Scott Braun, HS3 principal investigator, Goddard Space Flight Center, Greenbelt, Md. * Tom Miller, Global Hawk pilot, Dryden Flight Research Center, Edwards, Calif. * Marilyn Vasques, HS3 project manager, Ames Research Center, Moffett Field, Calif. * Brian McNoldy, senior research associate, University of Miami Rosenstiel School of Marine and Atmospheric Science NASA social media followers may submit questions on Google+ or Twitter in advance and during the event using the hashtag #NASAHS3. Before the Hangout begins, NASA will open a thread on its Facebook page where questions may be posted.
