Bunburra Rockhole Meteorite: Introduction

Before dawn on a July morning in 2007, a streak of fire crossed the sky above the Nullarbor and burned out high over the saltbush. No one was awake to see it. But cameras were. Two weather-proof observatories, staring patiently upward through the desert night, caught the entire flight on film - and from those two photographs, scientists did something that had never been done before. They calculated where the rock would land, drove out across the plain, and found it. They also calculated where it had come from: not just "space," but a specific orbit, a specific corner of the solar system. The meteorite they recovered is called Bunburra Rockhole.

Meteorites are common; meteorites with a known address are vanishingly rare. Most are stumbled upon long after they fall, with no record of where in the sky they came from. Bunburra Rockhole changed that. It was the first meteorite recovered by the Desert Fireball Network, a chai...

Bunburra Rockhole Meteorite: Reading an Orbit Backwards

Knowing where a meteorite fell is useful. Knowing where it lived for the previous few hundred million years is extraordinary. Because the cameras recorded not just the brightness but the precise geometry of the fireball, the team could reconstruct the rock's orbit around the Sun ...

Then the rock itself began to surprise everyone. At first glance it looked like a familiar kind of meteorite - a basaltic achondrite, born of ancient volcanism, of the sort usually traced to the giant asteroid Vesta. But its chemistry refused to fit. The ratios of oxygen and chro...

Bunburra Rockhole Meteorite: Why the Nullarbor

Mon, 22 Jun 2026 00:00:00 GMT

It is no accident that this happened here. The Nullarbor is one of the best places on Earth to hunt for fallen stars. The land is flat, pale, and almost treeless, so a dark meteorite stands out like a smudge on a tablecloth. Rain is scarce, so stones weather slowly and lie undist...
