"On July 31 2013 a constellation of US defence satellites saw a streak of light
over South Australia as a rock from outer space burned through Earth’s
atmosphere on its way to crash into the ground below.
The impact created an explosion equivalent to about 220 tonnes of TNT. More
than 1,500km away, in Tasmania, the bang was heard by detectors normally used
to listen for extremely low-frequency sounds from illegal tests of nuclear
weapons.
These were two excellent indications that there should be a patch of ground
covered in meteorites somewhere north of Port Augusta. But how could we track
them down?
My colleagues and I who work on the Desert Fireball Network (DFN), which tracks
incoming asteroids and the resulting meteorites, had a couple of ideas: weather
radar and drones."
