I laughed when I saw this cartoon by Tom Tomorrow. But it turns out Drony has some brothers and sisters who aren’t quite as threatening:
NASA’s unmanned sentinels are autonomously flown. The NASA Global Hawk is well-suited for hurricane investigations because it can over-fly hurricanes at altitudes greater than 60,000 feet with flight durations of up to 28 hours – something piloted aircraft would find nearly impossible to do. Global Hawks were used in the agency’s 2010 Genesis and Rapid Intensification Processes (GRIP) hurricane mission and the Global Hawk Pacific (GloPac) environmental science mission.
“Hurricane intensity can be very hard to predict because of an insufficient understanding of how clouds and wind patterns within a storm interact with the storm’s environment. HS3 seeks to improve our understanding of these processes by taking advantage of the surveillance capabilities of the Global Hawk along with measurements from a suite of advanced instruments,” said Scott Braun, HS3 mission principal investigator and research meteorologist at NASA’s Goddard Space Flight Center in Greenbelt, Md.
