A \u223c37 kg meteoroid entered the atmosphere with a speed of 13.68\u00b10.09km s\u22121 and was observed ablating from a height of 85 km down to 18 km, having slowed to 3.28\u00b10.21km s\u22121. Despite the relatively steep 68.5\u2218 trajectory, strong atmospheric winds significantly influenced the darkfight phase and the predicted fall line, but the analysis put the fall site in the centre of Kati Thanda &#8211; Lake Eyre South. Kati Thanda has metres-deep mud under its salt-encrusted surface. Reconnaissance of the area where the meteorite landed from a low flying aircraft revealed a 60 cm circular feature in the muddy lake, less than 50 m from the predicted fall line. After a short search, which again employed light aircraft, the meteorite was recovered on the 31st December 2015 from a depth of 42 cm. Murrili is the first recovered observed fall by the digital Desert Fireball Network (DFN). In addition to its scientific value, connecting composition to solar system context via orbital data, the recover demonstrates and validates the capabilities of the DFN, with its next generation remote observatories and automated data reduction pipeline. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>E.
