The Western Australian and South Australian museums are both collaborators on the project.<\/p>\n<p>Team leader and planetary geologist, Professor Phil Bland, hand-dug the meteorite from a 42cm deep hole in a remote section of the lake bed just hours before the arrival of heavy rains that would have wiped away all trace of the fall site.<\/p>\n<p>\u201cIt was an amazing team effort &#8211; we got there by the skin of our teeth,\u201d Professor Bland said.<\/p>\n<p><iframe loading=\"lazy\" title=\"Curtin team successfully tracks and recovers a meteorite.

The impact site had deteriorated quite considerably in recent rain, and as a result was quite hard to see from the ground.\u201d<\/p>\n<p>Team member Robert Howie said the meteorite was embedded in the thick salt lake mud, and covered by softer and wetter mud due to rain which had fallen between the time of impact and recovery. Heavy rainfall has since started to fill Kati Thanda-Lake Eyre with water.<\/p>\n<p>Professor Bland said the meteorite \u2013 thought to be a chondrite or stony meteorite &#8211; provided an example of material created during the early formation of the Solar System more than 4.5 billion years ago.<\/p>\n<p>\u201cThis meteorite is of special significance as the camera observations used to calculate the fall positions have also enabled the solar system orbit of the meteorite to be calculated, giving important contextual information for future study,\u201d<\/p>\n<p>Professor Bland, who is supported by an Australian Research Council Laureate Fellowship, said the discovery held added significance for the Desert Fireball Network team.<\/p>\n<p>\u201cIt demonstrates beyond doubt that this giant machine that we\u2019ve built really works.<\/p>\n<p>\u201cWe\u2019ve got a lot more rocks on the ground. This recovery will be the first of many &#8211; and every one of those meteorites will give us a unique window into the formation of the Solar System.\u201d<\/p>\n<p>Professor Bland said the team certainly hadn\u2019t expected to spend New Year\u2019s Eve digging for a meteorite on Lake Eyre, but the result had made it all worthwhile.<\/p>\n<p>\u201cA big thanks to the Arabana people as well for giving us access to the lake surface at such short notice. We couldn\u2019t have done this without them.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Âé¶¹Ö±²¥&#8217;s Desert Fireball Network team has celebrated the New Year in style by
