Newman space junk likely part of Chinese rocket says experts as authorities flag months-long investigation
A Chinese rocket ship fuel tank that was discarded as the craft entered orbit and crashed back down to earth is the most likely source of the space junk that landed in WA’s north on Saturday, experts predict.
But police estimate it could take months to find the origins of the wreck which crash landed on a remote access road 30km east of Newman in WA’s Pilbara region on Saturday.
The wreckage — which measured more than 1m in diameter — was still yet to be moved on Monday afternoon.
According to police the debris was first found by mine site personnel at around 2pm on Saturday still on fire.
Eerie footage was released of police officers in full PPE inspecting the debris in the middle of the road.

As officials begin the potentially lengthy task of identifying where the carbon fibre fuel tank came from, experts have predicted it is most likely from the fourth stage of the Jielong rocket from China.
Flinders University associate professor and space archaeologist Alice Gorman said the orbital path and dimensions of the object makes it the likely culprit.
“It’s likely the fourth stage of a Chinese Jielong rocket, this is a fairly recent rocket which was made operational in 2022, only eight launches so far and they’ve all been successful,” she said.
“It’s a fourth-stage rocket with solid propellant and has been delivering a bunch of satellites every time it’s launched.
“This one looks like it was from the fourth stage which would’ve been discarded in orbit and so it’s returned to earth from orbit.”
The theory was backed by Dorota Mieczkowska of the UWA International Space Centre who said the re-entry prediction made it likely the object was part of the Jielong rocket body.
Not all were so quick to speak with confidence however, as Curtin Institute of Radio Astronomy executive director Steven Tingay said it was too soon to tell.
“I’ve seen that speculation online and I guess that’s possible but there’d need to be some evidence pinning it back to any particular object,” he said.
Officials were also careful not to lay the blame, saying it could take weeks or months of investigating.
Acting Pilbara Superintendent Les Andrews said there were no indications yet.
”There’s no specific nation involved or suggestion at all, there are 1000s and 1000s of satellites up in the sky, in orbit,” he said.
“They all require rocket propellant to obviously get launched out there, it’s certainly not something that we’re looking at regards to country of origin, because there’s so many out there, it’s not really relevant.”
Mr Andrews said the object was first thought to be a plane tyre, but he ultimately turned to AI for help to work out what it was.
“A few other suggestions were put forward, which proved incorrect so I punched a photo into artificial intelligence, and it provided these suggestions, it basically went off from there,” he said.
“The AI indicator was possibly space debris reentry, and that appears to be where we’re at.”
An Australian Space Agency spokesperson confirmed it was working with teams on the ground to identify the object.
“The debris is likely a propellant tank or pressure vessel from a space launch vehicle,” they said.
“The Agency is continuing the process of determining the exact nature of the debris and its origin through engagement with global counterparts.”
It comes more than two years after space debris from a satellite launch vehicle was found on Green Head beach — about 250km north of Perth — in July 2023.
The object was eventually traced back to an Indian rocket.
Mr Tingay said space junk re-entry was becoming more common with several dozen each year in Australia, most of which happening and are never found.
He said the risk to safety was ever increasing.
“The probability is low, but overtime as the number of these events increases then obviously the chances become higher, “ he said.
“This particular object landed on a road, on a mine site so the chances of a car going past or something else going past is obviously low but it’s sort of a matter of time until there’s a re-entry event over a populated area.”
Science and Innovation Minister Stephen Dawson said the Government was looking to technology to mitigate the risk of space junk falling.
“It’s not every day that we come across space debris, and I look forward to hearing more updates on this discovery in our State’s north,” he said.
“With Western Australia’s large size and sparse population density, the risk space debris poses is low.
“However, the Cook Labor Government understands that having access to the latest technology and data available to monitor space debris is paramount for space agencies, international governments, and the private space sector.”
