Let
me share Technology News about NASA Mission Sending Unmanned Aircraft Over
Hurricanes in 2012 – This year. Beginning this summer and over the next several
years, NASA will be sending unmanned aircraft dubbed “severe storm sentinels”
above stormy skies to help researchers and forecasters uncover information
about hurricane formation and intensity changes.
Several
NASA centers are joining federal and university partners in the Hurricane and
Severe Storm Sentinel (HS3) airborne mission targeted to investigate the
processes that underlie hurricane formation and intensity change in the
Atlantic Ocean basin.
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.
HS3
will use two Global Hawk aircraft and six different instruments this summer,
flying from a base of operations at Wallops Flight Facility in Virginia.
“One
aircraft will sample the environment of storms while the other will measure
eyewall and rainband winds and precipitation,” Braun said. HS3 will examine the
large-scale environment that tropical storms form in and move through and how
that environment affects the inner workings of the storms.
