Mystery object that washed up on Australian coast could be a piece of Indian rocket: Space experts
Melbourne (PTI): A dome-shaped mysterious object has washed up on a remote Australian beach, amid speculation that it could be from a 20-year-old Indian rocket that was used for launching a satellite.
The canister was discovered near the beach in Green Head in Western Australia (WA) about 250 kilometres north of the city of Perth on Saturday. When contacted by PTI, the Indian Space Research Organisation (ISRO) sources confirmed receipt of a formal communication from the Australian Space Agency. However, they did not provide the details.
The bizarre-looking object has been declared a piece of space junk, while national agencies, including the Australian Space Agency (ASA), continue working to identify its origin.
The copper-coloured bulky cylinder, which stands taller than a human, appears to be damaged at one end and is covered with barnacles, indicating that it has spent a significant amount of time at sea before washing up.
"We are currently making enquiries related to this object located on a beach near Jurien Bay in Western Australia. The object could be from a foreign space launch vehicle and we are liaising with global counterparts who may be able to provide more information," the ASA said in a series of tweets on Monday.
As the origin of the object is unknown, the community should avoid handling or attempting to move the object, it said, adding that if the community spot any further suspected debris they should report it to local authorities and notify the agency.
"We are committed to the long-term sustainability of outer space activities, including debris mitigation, and continue to highlight this on the international stage," the agency said.
In a statement, Western Australia Police said that it is believed the item is space debris and will be managed as such until it can be determined otherwise. However, a space expert says the object could be from a 20-year-old Indian rocket.
European Space Agency engineer Andrea Boyd said experts believed the item fell from an Indian rocket launching a satellite, the Australian Broadcasting Corporation reported.
"We're pretty sure based on the shape and the size, it is an upper-stage engine from an Indian rocket that's used for a lot of different missions," she said.
"Based on the amount of barnacles, it's probably not the one from this year," she said. She said it could be 20 years old, the report added.
"But at the same time, when it gets thrown around the ocean it does tend to look older than it would normally."
Boyd said the engine was designed to fall off after the launch.
"It takes a lot of effort to get up to orbit, so the first and second and third stage (engines) usually fall off and end up in the Indian Ocean, so it's probably come from that with the currents and washed up on the beach," she said.
Within an hour of the first media report on the unusual find, many social media users already came up with a theory the object was a piece of space junk from an Indian rocket, the Sydney Morning Herald newspaper reported.
Space experts agreed, with Australian National University astrophysicist Dr Doris Grosse and Flinders University space archaeologist Dr Alice Gorman believing it was likely a fuel cylinder from the third stage of a launch by India's space agency, it said.
Some even theorised the debris could have come from a specific mission PSLV-CA C46 which launched in May 2019 and dropped some debris in the ocean to Australia's north-west and south-east, the report added.
Police earlier labelled the object as "hazardous" as they worked to identify if there was a risk to the community.
After analysis of the object, the Department of Fire and Emergency Services and the Chemistry Centre of WA found it posed no risk to the community. But Boyd said it was important people did not touch the object.
"It might still have some residual fuel and you just don't want to get people touching that," she said.
Western Australia Premier Roger Cook said the object could end up at the WA Museum.
"I did make the observation this morning that perhaps this will be an addition to the Sky Lab pieces that we have in the museum and might add to our growing collection of space debris that seems to be collecting in WA," he said.
Space debris both man-made and natural has a habit of coming down in WA's vast outback, although it is rare for it to be found washed up on the state's 12,895 kilometres of coastline. Most famously, the Skylab space station came hurtling back to Earth in 1979, with pieces of the rogue station found in the most remote of outback locations in Balladonia, north-east of Esperance in WA's south.
The local council hit NASA with a USD 400 littering fine, which reportedly remains unpaid. But scientists with their eyes trained on the skies have also recovered fragments of space rocks which have made it through the atmosphere and slammed into the ground in WA's outback.

Rupee falls 8 paise to hit all-time low of 84.50 against US dollar
Mumbai, Nov 21: The rupee depreciated 8 paise to settle at an all-time low of 84.50 against the US dollar on Thursday, dragged down by massive sell-off in domestic equity markets and surging crude oil prices amid a volatile geopolitical situation.
According to forex traders, the American currency strengthened due to safe-haven appeal amid escalating tension between Russia and Ukraine, while the continuous outflow of foreign funds also put pressure on the domestic unit.
At the interbank foreign exchange, the rupee opened at 84.41 and touched the lowest-ever level of 84.51 against the greenback during intra-day. The unit ended the session at 84.50 against the dollar, surpassing its previous all-time low closing level of 84.46 recorded on November 14.
On Tuesday, the rupee had settled flat at 84.42 against the US dollar.
The foreign exchange market was closed on Wednesday on account of assembly elections in Maharashtra.
"We expect the rupee to trade around 84.5 against the dollar by end December. A strong dollar continues to create a depreciating bias for currencies globally and is likely to sustain FPI outflows from Indian markets in the near-term.
"However, interventions by the Reserve Bank of India (RBI), supported by India's healthy foreign exchange reserves, should help keep rupee volatility in check," said Rajani Sinha, Chief Economist, CareEdge Ratings.
FPIs have withdrawn approximately USD 4 billion from Indian markets in November, following a record USD 11 billion in outflows in October. While high US Treasury yields and a strong dollar have contributed to these outflows, other domestic factors have also been at play, such as muted corporate earnings and high valuations.
"Over the medium-term, we expect the rupee to trade around 84 by the end of FY25, supported by India's strong fundamentals, including a manageable current account deficit, inclusion in global bond indices, fiscal consolidation and stronger growth relative to other emerging markets. These factors should help maintain India's attractiveness as an investment destination," Sinha added.
Sinha further said "going forward, it will be crucial to monitor the implementation of Trump's policies and China's response, as these will play a key role in shaping market dynamics."
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading lower by 0.02 per cent at 106.66.
Brent crude, the global oil benchmark, surged by 1.84 per cent to USD 74.15 per barrel in futures trade.
Jateen Trivedi, VP Research Analyst - Commodity and Currency, LKP Securities, said the rupee weakened as pressure mounted due to the dollar scaling higher above 106.65 amidst renewed global uncertainties with geopolitical tensions between Russia and Ukraine adding to global risk aversion.
At the same time, sell-off in domestic equity markets was fuelled after the Adani Group faced bribery and fraud charges in the US. "This has further fuelled FII outflows, continuing the trend of capital flight from Indian markets," Trivedi said.
In the domestic equity market, the 30-share BSE Sensex tumbled 422.59 points, or 0.54 per cent, to close at 77,155.79 points, while Nifty tanked 168.60 points, or 0.72 per cent, to settle at 23,349.90 points.
Foreign Institutional Investors (FIIs) were net sellers in the capital markets on Thursday, as they offloaded shares worth Rs 5,320.68 crore, according to exchange data.
