stargazer terminate 2015 by find a cute meteorite just hours before floods would have hidden it forever . They then narrowly avoid getting trapped by the same floods . All following remarkable detective study to locate the place rock .
Most meteorites are found without us knowing anything about their track to Earth . “ It ’s like having a crew of random rocks dumped in your backyard , ” Curtin University ProfessorPhil Blandtold IFLScience . However , if we have photographic grounds of their path through the atmosphere , we can calculate their area , making meteorites we can agree to these image terrifically valuable .
Bland told IFLScience it is sometimes possible to couple the meteorite to a family of asteroids , and sometimes even a specific asteroid from which the meteorite came . Almost all meteorites are 4.5 billion years old , former than the Earth , and base their origins could tell us how rock geological formation take issue with length from the Sun .

Half of the 20 meteorites whose course have been photographed were complete luck , fit in to Bland , such as the one that landed near a football game mate , its path filmed by numerous fan . The rest ensue from a internet of cameras that scan the sky looking for fireballs ( undimmed meteors ) and compute the landing place sites of those prominent enough to make it to the ground .
Bland leads the Desert Fireball internet , 32 photographic camera strategically place across Western and South Australia . “ Our advantage is that we are doing this in a place where we have it away we can retrieve meteorite on the ground , ” Bland tell IFLScience . Other meshing fall back most of their chase meteorite in the vegetation .
The meteorite Bland ’s squad has recall landed in Kati Thanda - Lake Eyre on November 27 . This dry lakebed normally represents a perfect post to discern something unusual , but big rains have produced one of its rare , butspectacular , flood . The level of mud and salt deposited in the process would have exit no hope of finding the meteorite in their wake , urge on a desperate pursuance to find the landing site in prison term .
Combining trail picked up by four cameras , reports from topical anaesthetic , airy watch , a droning and the local knowledge of the Arabana indigenous population , Bland manus - dig the 1.7 - kilogram ( 4 - pound ) rock from a 42 - cm ( 17 - inch ) kettle of fish at a site 6 kilometers ( 4 miles ) from the lake ’s border . After hightailing it back to the near hotel on New Year ’s Eve , Bland says the squad had expected to be flooded in , and may have been the last car out before the dirt cut was keep out for the floods ' continuance .
Professor Phil Bland celebrate finding his first Desert Fireball internet meteorite . He called the task punk compared to distance agencies ' billion dollar missions to revert samples from asteroid . Curtin University / Desert Fireball connection
The team have track record for 10 other fireballs they expect to have produce meteorites , but Bland is n’t upset about floods at these placement . The success , he say , “ demonstrates beyond dubiousness that this giant machine that we ’ve built really works . ”
The rock itself is a chondrite , easily the most common type of meteorite , but Bland hope isotopic analysis will reveal when it was tap off a larger physical object and help us determine its history .
