The balloons, originally designed to monitor on Earth, can collect data and detect low-frequency, infrasound using micro barometers.
Researchers tracked the routes of these balloons using GPS as they can sometimes sail for hundreds of miles and land in hard-to-reach places.
¡°Our balloons are basically giant plastic bags with some charcoal dust on the inside to make them dark. We build them using painter¡¯s plastic from the hardware store, shipping tape, and charcoal powder from pyrotechnic supply stores,¡± Dr Bowman said.?
¡°When the sun shines on the dark balloons, the air inside heats up and becomes buoyant. This passive solar power is enough to bring the balloons from the surface to over 20km (66,000 ft) in the sky,¡± he explained.?balloons, originally designed to monitor on Earth, can collect data and detect low-frequency, infrasound using micro barometers.
