UPDATE: After 53 years in orbit, an errant spacecraft is expected to imminently fall back to Earth, but space tracking researchers aren’t exactly sure where the craft will come screaming back into our atmosphere, or when.
The European Space Agency (ESA) predicts that the half-ton Kosmos 482 will crash-land on the surface of our planet sometime between Friday evening and early Saturday morning.
The Centre for Orbital and Reentry Debris Studies (CORDS) more specifically puts the timing somewhere in a nine-hour window of 1:54 a.m. ET on May 10, meaning reentry could happen any time between late afternoon Friday to the early hours of Saturday.
Aerospace, the American nonprofit research and development center that runs CORDS, currently predicts that the craft could land anywhere between 52 degrees north and 52 degrees south latitude.
The irony in the location is that the area covers almost every country on Earth, except Russia — the successor to the USSR, who launched the rocket as part of their Venus exploration program in 1972.
Aerospace is reassuring earthlings that while there is a small risk of being in the path of the falling craft, “any one individual on Earth is far likelier to be struck by lightning than to be injured by Kosmos 482.”
“We definitely do not expect Kosmos 482 to land in your yard specifically. Given the nature of its orbit, most of the Earth is still in play for its reentry, and consequently it is far more likely to land in the ocean or an unpopulated area.”

The craft, called Kosmos 482, was launched in 1972 with the intended destination of Venus. However, a rocket malfunction kept the probe inside of Earth’s orbit and it’s been stuck there, gradually decaying for more than 50 years.
Dutch scientist Marco Langbroek, with Delft University of Technology, told The Associated Press that while the mass of metal weighs about half a ton, it’s relatively small.
There’s a chance it will break up on re-entry into Earth’s atmosphere, but even if it doesn’t, “the risk is similar to that of a random meteorite fall, several of which happen each year. You run a bigger risk of getting hit by lightning in your lifetime,” Langbroek said.
The chance of the spacecraft hitting someone or something “cannot be completely excluded.”
Langbroek told Space.com that he pegs the current forecast for its re-entry for May 10, plus or minuAerospace, the American nonprofit research and development center that runs CORDS, currently predicts that the craft could land anywhere between 52 degrees north and 52 degrees south latitude.

He estimates that Kosmos 482 will land with an impact velocity of approximately 242 km/h.
After the craft was originally launched, most of it returned to Earth within a decade. Researchers believe the landing capsule — a spherical object about one metre in diameter — has been circling the world in a highly elliptical orbit for the past 53 years, gradually dropping in altitude.
In the 1970s, the highest point of the orbit was almost 10,000 kilometres above Earth’s surface, but now it’s below 400 kilometres and rapidly dropping.
There are concerns that after more than half a century in orbit, both the heat shield and parachute may be compromised or out of order.
A failure in the heat shield would be preferable, Jonathan McDowell with the Harvard-Smithsonian Center for Astrophysics told AP in an email, explaining that the spacecraft would burn up in its dive through the atmosphere.
If the heat shield holds, he said, “it’ll re-enter intact and you have a half-ton metal object falling from the sky.”
The spacecraft could re-enter anywhere between 51.7 degrees north and south latitude — as far north as Edmonton, Alta., and almost all the way down to South America’s Cape Horn. But since most of the planet is water, “chances are good it will indeed end up in some ocean,” Langbroek said.
