The Soviet-era spacecraft was intended to land on Venus in the 1970s, and is expected to return to Earth and be restrained soon.
According to experts in space fragment tracking, it is too early to know where the mass of halfton metal will descend, and how much of it will survive the re-entry.
Dutch scientist Marco Langlock predicts that the spacecraft's failure will re-enter the country around May 10th. He estimates that if it remains unharmed it will crash at 150mph (242km/h).
“It's not without risks, but you shouldn't be too worried,” Langbroke said in an email.
Even if the objects are relatively small and do not fall apart, “the risk is similar to the risk of a random metstone fall, some of which occur every year. There is a greater risk of being hit by lightning in your lifetime,” he said.
He added that there is a possibility that the spaceship could actually attack someone, or something is small. “But that cannot be ruled out entirely.”
The Soviet Union launched the spacecraft known as the Cosmos 482 in 1972. This is one of a series of Venus missions. However, it never did it from Earth orbit due to the rocket's malfunction.
Most of them fell within ten years. However, Langbroek and others believe that the landing capsule itself, a sphere about three feet (1 meter) in diameter, has been circling the world in a very elliptical orbit for the past 53 years, gradually decreasing at altitude.
It is highly likely that a 1,000lb-plus (nearly 500kg) spacecraft will survive the re-entry. It was built to withstand the descent through the atmosphere of Venus' carbon dioxide and thickness, according to Langbrog of Delft University of Technology in the Netherlands.
Experts doubt that the parachute system will function for many years. Also, heat shields can be compromised in orbit for a very long time.
Jonathan McDowell of the Harvard Smitonian Astrophysics Center says that the spacecraft burns out when the heat shield breaks down and the spacecraft burns into the atmosphere. However, if the heat shield is held, “it reenters unharmed and causes a halfton metal object to fall out of the sky.”
The spacecraft could travel almost all the way to Cape Horn in South America, 51.7°N, 51.7°S, or London and Edmonton in Alberta, Canada. However, since most of the planets are water, “opportunities can be good.
In 2022, the Chinese booster rocket returned to uncontrolled Earth, and in 2018, the Tiango-1 space station re-entered the South Pacific Earth atmosphere after an uncontrolled re-entry.
