A The Soviet era A spacecraft aims to land On Venus In the seventies of the twentieth century, it is expected to collapse soon to Earth.
It is too early to know where the mass of half a ton of metal can descend or the amount of what will return to his return, according to what he said Tracking space debris Experts.
Dutch scientist Marco Langberck predicts that the failed spacecraft will return to about 10 May. It is estimated that he will collide at 150 miles per hour (242 km per hour), if he remains intact.
“Although there is no danger, we should not be very concerned,” Langbroke said in an e -mail.
The object is relatively small, and even if it does not collapse, “the danger is like a risk Naisurit random fallAnd many of them happen every year. You are at greater risk of beating in your life. “
He added that the chance of the spacecraft hits someone or something small. “But it cannot be completely excluded.”
The Soviet Space Contest, known as Kosmos 482 in 1972, launched one of a series of flower tasks. But it did not come out of the Earth’s orbit due to a missile defect.
Most of them came down within a decade. But Langbroek and others believe that the landing capsule itself – a spherical object about 3 feet (1 meters) in the country – has been around the world in a very oval orbit over the past 53 years, as it gradually decreased on the height.
It is completely possible to survive the space vehicle with an area of 1000 pounds (approximately 500 kilograms). “It was built to bear the landing through the atmosphere of Venus Carbon dioxide.”
Experts doubt that the umbrella system will work after many years. The heat shield may also be at risk after a long time in orbit.
The Harvard Smithson Center for Astronomical Physics, Jonathan McDawell, said in an email, that it would be better if the heat shield fails, which could cause the spacecraft burning while diving during the atmosphere. But if the heat shield is steadfast, “it will return to healthy and you have a metal body half a ton that falls from the sky.”
The spacecraft can re -enter anywhere between 51.7 degrees north and south, or north in the far north of London and Edmonton in Alberta, Canada, almost to Cape Horn in South America. But since most of the planet is water, “good opportunities will actually end in some oceans.”
