Soviet-era probe meant for Venus crashes off Indonesia
A Soviet-era space probe launched in 1972 has re-entered earth's atmosphere and crashed into the Indian Ocean, Russian authorities say.
The Russian space agency Roscosmos said the spacecraft, known as Kosmos 482, entered the atmosphere at 4.24pm AEST before hitting the waters west of Jakarta, Indonesia.
No information was provided on potential damage or debris.
The European Space Agency also concluded that re-entry had likely occurred.
Between 1961 and 1983, the Soviet Union sent several probes to Venus as part of the Verena program to explore the planet.
While several succeeded in landing on the planet's surface and transmitting data back to earth, Kosmos 482 went astray shortly after lift-off.
Kosmos 482 was launched on March 31, 1972 and was scheduled to make a controlled landing on Venus.
However, due to a failure of the launch vehicle, the capsule failed to escape the earth's gravity and has been orbiting the planet for 53 years.
"The device was launched to explore Venus but remained in a high elliptical orbit around earth due to a malfunction in the upper stage and gradually approached the planet," Roscosmos said.
The probe's descent was monitored by an automated system designed to detect hazards in near-earth space, according to the agency.
Weighing nearly 500kg and measuring about a metre in diameter, the probe's crash had been widely anticipated by space agencies although its final landing site had remained uncertain.
Before Saturday's uncontrolled return to earth, experts had warned the spacecraft could survive re-entry intact due to its robust construction, originally built to withstand the harsh descent through Venus's atmosphere.
However, Roscosmos stated that "Kosmos 482 no longer exists".

Aussies stunned by ‘fireball' meteor
Residents in Western Australia have been stunned by a 'fireball' meteor that lit up the skies. The bright fireball passed through the skies about 6am on Sunday over the Central Wheatbelt, producing a brilliant yellow flash and a trail of bright green. Witnesses were able to catch a glimpse of the early-morning meteor from Perth to the Goldfields, however, experts are yet to determine where it eventually landed. Residents in Western Australia have been stunned as a meteor lit up the skies on Sunday morning. Supplied Credit: Supplied The Perth Observatory said the astronomical sight was 'most likely an iron meteor' which had been 'orbiting within the inner Solar System'. 'To shine that brightly, the fireball — technically known as a bolide — would have been about the size of a cricket ball to a basketball,' the observatory said online. The 'fireball' meteor left a green trail in its wake Supplied Credit: Supplied According to Perth Observatory's Matthew Woods, the meteor would have been travelling between 16 to 60km per second, leaving behind a trail of green as the built-up friction melted. He told 9News it was 'one hell of a meteor'. 'That was very nice … little surprise for Mother's Day,' he said. Some thought the light was the moon. Supplied Credit: Supplied The meteor was spotted across much of the state. Supplied Credit: Supplied Online, witnesses were dumbfounded by the 'spectacular' sight, with some believing it was an aeroplane. 'Never seen anything like it,' one person wrote. 'Thought someone was driving at us with high beams on at first,' said another, who watched it pass overhead from Newdegate. A resident from Mt Magnet said they initially thought the 'huge and burning bright orange-red' light was 'the moon until it moved'. The meteor created a bright orange and red light. Supplied Credit: Supplied Some thought the meteor was the Kosmos 482, a Soviet-era spacecraft that plunged back to earth more than 50 years after its failed launch to Venus. However, Curtin University astrophysicist Steven Tingay told the ABC it was unlikely the fallen spacecraft, which likely landed over the Indian Ocean on Saturday, though European and US agencies are yet to confirm its exact location.

Western Australia dodges bullet as Soviet-built Kosmos 482 lands in Indian Ocean, ending 53 years in orbit
WA had a 'lucky escape' after it avoided being hit by a doomed Soviet spacecraft at the weekend, with the State at one point right in the firing line. Kosmos 482 finally made its way out of orbit and back to Earth on Saturday after being launched by the Soviet Union in 1972. According to EU Space Surveillance and Tracking, the spacecraft likely landed in the Indian Ocean west of Indonesia after 2pm Perth time, just 38,000,000km away from its planned destination of Venus. While it appears the capsule ended up landing in the ocean, the uncontrolled nature of its re-entry meant there was a large degree of uncertainty as to where it would land, with some modelling predicting it could hit WA. University of Western Australia Professor David Coward, one of two Australian signatories to the International Asteroid Warning Network, a UN-backed planetary defence organisation, said WA was almost in the firing line. 'It was a lucky escape, it's all about probability,' he said on Sunday. 'The satellite track, because the satellite orbits the Earth is every 90 minutes or so, follows a slightly different track, one of the tracks crossed Western Australia around Exmouth and then exited WA around Esperance. 'There was a real probability and in fact if this probe had a delayed re-entry it would have re-entered over WA and in fact only yesterday the best prediction for re-entry was over Western Australia.' Encased in titanium and weighing in at almost half a tonne, Kosmos 482 was a landing module which never left orbit due to a malfunction of the launch vehicle. Professor Coward said the chances of the craft hitting a suburban area was always slim but the impact if it did could have been deadly. 'If it actually re-entered over a city, there could be a fatality,' he said. 'The probability of it actually causing injuries is quite remote, mainly because of the vastness of the land mass compared to the size of the satellite. 'The satellite would essentially be like a bullet, it travels at what's called terminal velocity which is hundreds of kilometres a second so it would have formed a crater. 'There would have been a small explosion, because the body is about a metre if I recall in size so it would have been like a projectile coming down from space.' According to Professor Coward international rules state the launcher of spacecrafts are responsible for collecting any space junk that returns onto Earth but it is unclear yet whether Kosmos 482 would be retrievable as it may have sunk to the bottom of the ocean. Perth Observatory's Matt Woods said WA was a magnet for space junk. In 2023, an old Indian rocket washed up on a beach in Green Head. And in 1979, Sky Lab famously plummeted back to Earth and crashed near Esperance. '(Kosmos 482) was designed to survive the atmosphere, so you don't really want that falling on you at any time,' Mr Woods said. 'This one was kind of rare in the sense that it was a failed mission to Venus, it just never escaped Earth's atmosphere,' he said. 'Basically what ended up happening was it just orbited around the Earth for ages until the orbit decayed so much that it came back after 50 years. 'But we do get a lot of space junk hitting our atmosphere and burning up in the atmosphere.'
