Our summer science series continues this week with an episode of The Otago Chronicles podcast, hosted by Max Balloch. In this episode, Max talks to Associate Professor James Scott from the University of Otago Department of Geology about looking up at the night sky and the hunt for what would’ve been New Zealand’s 10th meteorite.

At a few dozen schools across New Zealand, special cameras are keeping watch for meteors streaking across the inky darkness. They’re part of a network called Fireballs Aotearoa – detecting meteors and connecting schoolkids to the night sky – established in early 2022.
Most meteors – space rocks usually originating from the asteroid belt – burn up as they fly through the atmosphere, dying in a blaze of glory. A handful might make it to the Earth’s surface intact.
On 28 August 2022, three of the cameras picked up a fireball – an especially bright meteor that “winks out” just above the ground. “We couldn’t believe that it had landed right in the middle of our camera network, that we’d just deployed,” says James.

The meteor’s trajectory was calculated, narrowing its potential point of impact to a farm west of Outram in Otago. Once a meteor touches the Earth’s surface, it’s known as a meteorite.
A two-day meteorite hunt ensued – about 100 students, researchers, and volunteers scoured the countryside for what would be New Zealand’s tenth meteorite.
