When a space capsule landed in the South Australian outback in December, it was carrying precious items from deep space that had never been seen on Earth.
Scientists have revealed what they have found so far inside the Japanese capsule. Their trove* includes the world’s first samples of gas from deep space and sub-surface material from an asteroid — and also a mystery artificial object that has them stumped*.
They are hoping that the sub-surface material, a cluster* of different-sized grains of black sand, will help answer important questions about how life evolved on Earth, such as whether key ingredients actually came from asteroids.
The samples were collected from the 4.5 billion-year-old Ryugu asteroid, which is more than 15 million kilometres from Earth.
Scientists were impressed by the 5.4g collection — more than 50 times the 0.1g target — retrieved from the capsule that was launched from the Japanese spacecraft Hayabusa 2.
The collection included the mysterious “artificial object”, which the Japan Aerospace Exploration Agency (JAXA) said could possibly be “aluminium separated from the sampler horn (a tube used to pick up rock and sand)” during the collection process.
Expedition photographer Anthony Gordon, who took photographs of the capsule landing near Woomera in the South Australian outback, said he was excited by what had been found.
“It is ridiculous what they’ve been able to achieve,” he said.
“The fact that they were expecting to get 0.1g of dirt out of it and they end up getting 50 times that is extraordinary.
“It could have massive implications* for medicine and for science, for a lot of things, just from a pile of dirt.”
Meanwhile, the Federal Government has announced a plan to make Australia a space manufacturing* hub by 2030.
Under the plan, Australia will take part in international space missions, make its own satellites and be globally recognised for its rocket launch pads.
The plan was unveiled* on February 19, the same day NASA’s Perseverance rover touched down on Mars in a mission to look for signs of ancient life.
South Australia is increasingly seen as the space jobs hub of Australia and is home to the Australian Space Agency.
Adelaide start-up* Southern Launch has already established rocket launch sites at Whalers Way on the tip of the Eyre Peninsula and at Koonibba, near Ceduna.
The company successfully launched two rockets in 2020.
Queensland and the Northern Territory are also looking to establish rocket launch sites as the Federal Government aims to triple the size of Australia’s space business to $12 billion a year and to create up to 20,000 extra jobs in the industry by 2030.
