Unidentified object on Australian beach may be part of Indian rocket launcher

(2023/07/18)


The Australian Space Agency said on Monday it was making enquiries related to a mysterious cylindrical object that washed ashore on Western Australia's Jurien Bay.

The agency [1]detailed that it was "working to confirm whether the object could be part of a foreign space launch vehicle that has washed up on shore, and liaising with global counterparts who may be able to provide information about the object."

It warned the local population against handling or moving the object. Residents of the area were the ones to find the object and report it to the police.

Western Australian (WA) Police [3]reportedly determined the item wasn't a risk, after originally treating it as hazardous. WA Police also [4]confirmed it "did not originate from a commercial aircraft," thereby dispelling speculation that it could be from 2014's missing flight MH370.

Multiple [9]industry professionals and experts have determined the object could likely be a fuel cylinder from the third stage of India's Polar Satellite Launch Vehicle (PSLV). This is not an unfounded conclusion – the item does look eerily similar to [10]photos of the PSLV, which India has used since 1993.

The Indian Space Research Organization (ISRO) used the PSLV to launch its latest lunar mission, Chandrayaan-3, last Friday.

After the PSLV expels its spacecraft, its first three stages become debris that's typically not recovered. Its fourth stage is used as an orbital platform.

The third stage comes into play after the atmospheric phase of the launch, where it provides 250kn of thrust, burning 7.6 long tons of Hydroxyl-Terminated Poly Butadiene (HTPB) solid propellant, burnt for a few seconds shy of two minutes.

[13]

Safety data sheets do warn against human contact with HTPB, although most warnings are issued for high temperatures. Ecological dangers of HTPB are less understood.

"Uncontrolled reentry is not disposal but abandonment," [14]said space environmentalist and astrodynamicist Moriba Jah. Jah also concluded the item is "likely from India's PSLV system."

The space environmentalist warned that such events will only become more frequent with even larger items – the size of a bus or car – eventually landing in populated areas.

[15]

This kind of potential space debris problem is not isolated to India alone and space missions have become more common globally. China, for instance, is notorious for [16]ambiguous crash landings of its Long March 3B.

In June, state-sponsored media [17]reported the China Academy of Launch Vehicle Technology (CALT) had developed a parachute system to guide its rockets to a predetermined landing zone.

Here's hoping. ®

What, not alien ?

alain williams

I thought that everything unidentified had to be classed as being from a civilisation light years away.

Does this mean that we might be entering a phase of objective reality ... at the start of the newspaper silly season ?

Maybe we should get worried that the Australian government is suppressing the truth.

It's the northern hemisphere silly season - but maybe not in Oz.

BBC clickbait

FlamingDeath

They described it as mysterious, I didn’t click

Re: BBC clickbait

Jellied Eel

Pretty much everything is a mystery to the Bbc. They're currently getting all excited about hot weather and if McDonalds has a 'Me Too' problem, which the Bbc does and it still hasn't sacked it's pervy presenter.

But if anyone can prove this used to be in the air, then it was a genuine UFO! Ish. At least till it's identified.

Re: BBC clickbait

John Brown (no body)

In general, you don't sack people on medical leave and the enquiry is still ongoing, so that's not really a surprise.

Uncontrolled reentry?

Anonymous Coward

Looks like the thing floated around for a long time before washing up on a beach. The generally accepted safe deorbiting method is to bring things down in the pacific. Looks like this bit didn't sink and floated around until it eventually found land. They've been using these for ages, so it may not the one from last week.

Re: Uncontrolled reentry?

Paul Herber

Doesn't look like a floaty-float-float thing, looks more like a sinky-sink-sink metal object.

The preferred target is the [1]Spacecraft Cemetery but if this is a solid rocket stage then there wasn't much choice about where it came down. ( [2]That's not my department ...)
