A half-ton Soviet spacecraft that never made it to Venus 53 years ago is expected to fall back to Earth this weekend.

Built to land on the solar system's hottest planet, the titanium-covered spacecraft may survive its fiery, uncontrolled plunge through Earth's atmosphere, predicted to occur on Saturday. But experts said it likely would come down over water, covering most of the world, or a desolate region.

The odds of it slamming into a populated area are “infinitesimally small,” said University of Colorado Boulder scientist Marcin Pilinski.

“While we can anticipate that most of this object will not burn up in the atmosphere during reentry, it may be severely damaged on impact,” Pilinski said in an email.

By Friday, all indications pointed to a reentry early Saturday morning, US Eastern Time, give or take several hours. While space debris trackers around the world converged in their forecasts, it was still too soon to know exactly when and where the spacecraft known as Kosmos 482 would come down. That uncertainty was due to potential solar activity and the spacecraft’s old condition. Its parachutes were expected to be useless by now and its batteries long dead.

Dutch scientist Marco Langbroek estimated the impact speed at 150 mph (242 kph) if the spacecraft remains intact.

The Soviets launched Kosmos 482 in 1972, intending to send it to Venus to join other spacecraft in their Venera program. But a rocket malfunction left this one stuck in orbit around Earth. Gravity kept tugging on it and was expected to finally cause its doom.

Spherical in shape, the spacecraft — 3-foot (1-meter) across and packing more than 1,000 pounds (495 kilograms) — will be the last piece of Kosmos 482 to fall from the sky. All the other parts plummeted within a decade.

Any surviving wreckage will belong to Russia under a United Nations treaty.



Record Cold Grips Argentina, Chile and Uruguay

A polar air mass has brought record low temperatures to Argentina, Chile and Uruguay, causing at least 15 deaths and forcing governments to restrict gas supplies and activate emergency shelters.

The three South American countries have all recorded sharply below-zero temperatures as the polar air originated from Antarctica and swept across the region, said AFP.

In Argentina, at least nine homeless people have died from the cold this winter, according to NGO Proyecto 7.

The capital Buenos Aires recorded its lowest temperature since 1991 at -1.9 degrees Celcius (28.6 Fahrenheit) on Wednesday, while the coastal city of Miramar saw snow for the first time in 34 years. Further south, the town of Maquinchao recorded -18C on Tuesday.

Electricity demand caused cuts across Buenos Aires, leaving thousands without power for over 24 hours in some areas.

The government suspended gas supplies to industries and petrol stations Wednesday to ensure household supplies, and removed price controls on gas cylinders Thursday.

Desert snow

Uruguay declared a nationwide "red alert" after six people died, allowing President Yamandu Orsi's government to forcibly move homeless people to shelters.

Montevideo recorded its lowest maximum temperature since 1967 at 5.8C on June 30, according to meteorologist Mario Bidegain.

Chile also activated homeless shelter plans during the coldest days. The city of Chillan, 400 kilometers (250 miles) south of Santiago, hit -9.3C, according to the Chilean Meteorological Directorate.

"What happened this week in Chile and the Southern Cone in general is a cold wave caused by an escape of a polar air mass from Antarctica," climatologist Raul Cordero from the University of Santiago told AFP.

Snow even fell in parts of the Atacama Desert, the world's driest, for the first time in a decade.

"It is not so common for these cold air masses to extend so far north, so we cannot rule out that this is also caused by climate change," meteorologist Arnaldo Zuniga told AFP.

The region expects relief in the coming days, with Buenos Aires reaching 12C on Thursday, Montevideo 14C and Santiago 24.7C.

"I was quite surprised by the change from cold to hot -- the change was very drastic," student Dafne Naranjo, 18, said in Santiago.

Climatologist Cordero said heatwaves have become more frequent than cold spells in recent years.

"The frequency of heatwaves has tripled, whether in summer or winter, not only in the Southern Cone but throughout the world," he said.
