NASA sends drones into volcano plume

NASA flew three small unmanned aerial vehicles through the noxious sulfur dioxide plume escaping Costa Rica’s active Turrialba Volcano in March.

The repurposed military drones were outfitted with special instruments to gather data about the gas and volcanic ash.

The agency launched 10 flights using Aerovironment RQ-14 Dragon Eye drones acquired from the U.S. Marine Corps because manned flight into plumes is dangerous and the vehicles’ electric engines are less susceptible to ash damage.

Data acquired by the drones was matched up to that of the Terra spacecraft, one of the agency’s Earth-observing satellites, to calibrate spacecraft-based sulfur dioxide measurements.
