Man Keeps Rock For Years Thinking It's Gold. Turns Out It's a Super Rare Meteorite

Man kept a rock for years thinking it’s Gold but it turned out to be Super Rare Meteorite

David Hole in 2015 found a heavy reddish rock which was resting in yellow clay. He found this while prospecting in Maryborough Regional Park near Melbourne. He made every efforts to open it in the hope of finding gold nuggets inside the rock since the Australian gold rush peaked in the 19th century in Maryborough.

For cracking it, he used rock saw, angle grinder even a sledgehammer but all efforts went in vain since there was no gold nugget in it. He later discovered it to be a rare meteorite. 

Dermot Henry, Melbourne museum geologist said that it had a sculpted, dimpled look. It is formed when it comes through the atmosphere, where they melt on the outside as atmosphere sculpts it. He said that in his 37 years of experience at the museum he identified only two of the offerings to be genuine meteorites. David Hole took the ‘rock’ to the Melbourne Museum for identification and it turned out to be a meteorite. If you saw a rock on Earth like this, and you picked it up, it shouldn’t be that heavy

Researchers have published a paper to describe the 4.6 billion-year-old meteorite which has been named as Maryborough after the town near which it was found. The study has been published in Proceedings of the Royal Society of Victoria

 It weighs 17 kilograms and has a high composition of iron which makes it an H5 ordinary chondrite. There are small crystallised droplets of metallic minerals throughout it which are known as chondrules

Henry says that meteorites provide the cheapest method of space exploration. They provide clues to the formation of the solar system. Some of them provide information about the interior of the Earth. Some contain ‘stardust’ which is older than the solar system showing us the formation of stars. There are also rare meteorites which contain amino acids that are the building blocks of life. 

Researchers do not know exactly where the meteorite came from or how long it is present on Earth. Our solar system was a spinning pile of chondrite rocks and dust. Gravity pulled this material to form planets while the leftovers ended up in an asteroid belt. Henry explained that this meteorite might have come from the asteroid belt located between Mars and Jupiter. It crashed on Earth leaving the belt due to collisions between asteroids. 

Carbon dating suggests that it has been on Earth between 100 and 1000 years. It is much rarer than gold and is one of the 17 meteorites recorded in the Australian state Victoria. It has the second largest chondritic mass behind the 55-kilogram specimen found in 2003. It is quite amazing that this space rock got identified however it is not the first one to have an amazing story. One space rock took 80 years to make it to the museum after being through two owners.

Google drone delivery gets approval in Australia

Drone company “Wing“—an offshoot of Google’s parent company Alphabet, has been trialling deliveries of coffee and local medication using drones for past 18 years and will now go full time ahead as it receives approval from Aviation Watchdogs on Tuesday.

The spokesman for CASA, Australian aviation authority – Peter Gibson, told the media that the safety of the drones, traffic management system, drone pilot training and operational plans have been verified as 3,000 deliveries have been made which allowed the regulators to judge the safety of the project. He also said that the project was approved with strict conditions which included daylight operating hours around 11-12 hours a day and that they should not be fully automated but need to be piloted, banning the drones from crossing over main roads and staying at a specified altitude.

There were two issues that the regulators did not judge or focus upon which included the invasion of privacy of the residents as they fear that the drone might hinder with it and also the noise created by the drone which disturbed the residents , above whom it flew, since, they claim that the noise could be heard from even a double- glazed glass window. On the other hand, Gibson claimed that CASA did consider the noise issues of the project when it had given the green signal.

The initial area from where the operation will commence covers only one hundred homes lying in the suburbs of Crace, Palmerston and Franklin in Canberra as of now. However, the number is said to expand quickly as per the demand from the public. It is claimed that it will soon expand to Harrison and Gungahlin also.

When a customer uses an app to order any product , it is loaded onto a drone. The drone then hovers over its destination and lowers down the goods on a winch-line cable delivering it directly to the customer before flying away.

In the United States of America, UPS launched the country’s first authorised use of unmanned drones for transporting packages to recipients last month.

The drone delivery is believed to add $30m to $40m of additional annual revenue for ACT(Australian Capital Territory) businesses as estimated by the company.

The project is trumpeting reductions in delivery cost and also in the carbon emissions and predicts that these drones could deliver more than one in four takeaway food orders. It is estimated that this project could deliver 4-6% of all purchases in the Australian Capital Territory(ACT) by 2030.
