Fears Kessler syndrome theory becoming reality as flaming space junk lands on Earth
A piece of flaming suspected space junk has landed in the desert in Western Australia, prompting fresh concerns the much feared Kessler syndrome theory could soon become reality.
The burned up, charred object landed on an access road to a mine in the Pilbara region earlier this week, with the Australian Space Agency confirming it believes the unidentified item has come from outside Earth's atmosphere.
"The Australian Space Agency is working alongside local authorities in relation to the suspected space debris discovered in the Pilbara region of Western Australia," it wrote in a statement on X.
"The debris is likely a propellant tank or pressure vessel from a space launch vehicle."

Photos taken from the moment the flaming object was discovered show it still smoking, with space junk expert Professor Steven Tingay from Curtin University suggesting it was likely still on fire when it landed in the vast desert.

Speaking to IFL Science, the professor revealed he'd 'never seen this happen before', but suggested the risk of it happening more frequently is growing.
While it's still unconfirmed what caused the falling space debris, especially since no country or space station has claimed ownership of the anonymous object, it has sparked fresh concerns about the floating space debris around our planet and crucially, the risk of the Kessler syndrome theory coming to life.
What is the Kessler syndrome theory?
Theorised by NASA scientists Donald Kessler and Burton Cour-Palais back in 1978, the idea proposes that overcrowding in space could spark a chain reaction of collisions that would have catastrophic impacts.
The fear is that this chain could destroy satellites essential to maintaining humanity as we know it, halting crop production, destroying internet connections and preventing safe international travel.
In the worst-case scenario, the area of space described as low Earth orbit will then become uninhabitable by new satellites due to the rings of debris whizzing around the planet.
According to leading space archaeologist Alice Gorman, who wrote Dr Space Junk vs the Universe, there was 'no indication' the object was due to re-enter the Earth.
"There was no indication it was going to re-enter right now so people weren’t expecting it – when I went to look for re-entry predictions I couldn’t find anything, which is an indication of the suddenness of it," she told the Guardian.
A spokesperson for WA police said: "Initial assessments indicate the item was made of carbon fibre and may be a composite over-wrapped pressure vessel or rocket tank, consistent with aerospace components.
"The object remains under investigation, though its characteristics are consistent with known space re-entry debris … further technical assessment will be undertaken by engineers from the Australian Space Agency to assist in identifying its nature and source."
