CAPE CANAVERAL, Florida: The jig may be up for an “asteroid” that’s expected to get nabbed by Earth’s gravity and become a mini moon next month.
Instead of a cosmic rock, the newly discovered object appears to be an old rocket from a failed moon-landing mission 54 years ago that’s finally making its way back home, according to NASA’s leading asteroid expert. Observations should help nail its identity.
“I’m pretty jazzed about this,” Paul Chodas said. “It’s been a hobby of mine to find one of these and draw such a link, and I’ve been doing it for decades now.”
Chodas speculates that asteroid 2020 SO, as it is formally known, is actually the Centaur upper rocket stage that successfully propelled NASA’s Surveyor 2 lander to the moon in 1966 before it was discarded. The lander ended up crashing into the moon after one of its thrusters failed to ignite on the way there. The rocket, meanwhile, swept past the moon and into orbit around the sun as intended junk, never to be seen again – until perhaps now.
A telescope in Hawaii last month discovered the mystery object heading our way while doing a search intended to protect our planet from doomsday rocks. The object promptly was added to the International Astronomical Union’s Minor Planet Center’s tally of asteroids and comets found in our solar system, just 5,000 shy of the 1-million mark.
The object is estimated to be roughly 8 meters based on its brightness. That’s in the ballpark of the old Centaur, which would be less than 10 meters long including its engine nozzle and 3 meters in diameter.
What caught Chodas’ attention is that its near-circular orbit around the sun is quite similar to Earth’s – unusual for an asteroid.
“Flag number one,” said Chodas, who is director of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory in Southern California.
The object is also in the same plane as Earth, not tilted above or below, another red flag. Asteroids usually zip by at odd angles. Lastly, it’s approaching Earth at 2,400kph, slow by asteroid standards.
As the object gets closer, astronomers should be able to better chart its orbit and determine how much it’s pushed around by the radiation and thermal effects of sunlight. If it’s an old Centaur – essentially a light empty can – it will move differently than a heavy space rock less susceptible to outside forces.
That’s how astronomers normally differentiate between asteroids and space junk like abandoned rocket parts, since both appear merely as moving dots in the sky. There likely are dozens of fake asteroids out there, but their motions are too imprecise or jumbled to confirm their artificial identity, said Chodas.
Sometimes it’s the other way around.
A mystery object in 1991, for example, was determined by Chodas and others to be a regular asteroid rather than debris, even though its orbit around the sun resembled Earth’s.
Even more exciting, Chodas in 2002 found what he believes was the leftover Saturn V third stage from 1969′s Apollo 12, the second moon landing by NASA astronauts. He acknowledges the evidence was circumstantial, given the object’s chaotic one-year orbit around Earth. It never was designated as an asteroid, and left Earth’s orbit in 2003.
The latest object’s route is direct and much more stable, bolstering his theory.
“I could be wrong on this. I don’t want to appear overly confident,” Chodas said. “But it’s the first time, in my view, that all the pieces fit together with an actual known launch.”
And he’s happy to note that it’s a mission that he followed in 1966, as a teenager in Canada.
Asteroid hunter Carrie Nugent of Olin College of Engineering in Needham, Massachusetts, said Chodas’ conclusion is “a good one” based on solid evidence. She’s the author of the 2017 book “Asteroid Hunters.”
“Some more data would be useful so we can know for sure,” she said in an email. “Asteroid hunters from around the world will continue to watch this object to get that data. I’m excited to see how this develops!”
The Harvard-Smithsonian Center for Astrophysics’ Jonathan McDowell noted there have been “many, many embarrassing incidents of objects in deep orbit ... getting provisional asteroid designations for a few days before it was realized they were artificial.”
It’s seldom clear-cut.
Last year, a British amateur astronomer, Nick Howes, announced that an asteroid in solar orbit was likely the abandoned lunar module from NASA’s Apollo 10, a rehearsal for the Apollo 11 moon landing. While this object is likely artificial, Chodas and others are skeptical of the connection.
Skepticism is good, Howes wrote in an email. “It hopefully will lead to more observations when it’s next in our neck of the woods” in the late 2030s.
Chodas’ latest target of interest was passed by Earth in their respective laps around the sun in 1984 and 2002. But it was too dim to see from 8 million kilometers away, he said.
He predicts the object will spend about four months circling Earth once it’s captured in mid-November, before shooting back out into its own orbit around the sun next March.
Chodas doubts the object will slam into Earth – “at least not this time around.”

Fake asteroid? NASA expert IDs mystery object as old rocket

What did people eat before agriculture? New study offers insight
- Analysis of forms — or isotopes — of elements including carbon, nitrogen, zinc, sulfur and strontium in these remains indicated the type and amount of plants and meat they ate
WASHINGTON: The advent of agriculture roughly 11,500 years ago in the Middle East was a milestone for humankind — a revolution in diet and lifestyle that moved beyond the way hunter-gatherers had existed since Homo sapiens arose more than 300,000 years ago in Africa.
While the scarcity of well-preserved human remains from the period preceding this turning point has made the diet of pre-agricultural people a bit of a mystery, new research is now providing insight into this question. Scientists reconstructed the dietary practices of one such culture from North Africa, surprisingly documenting a heavily plant-based diet.
The researchers examined chemical signatures in bones and teeth from the remains of seven people, as well as various isolated teeth, from about 15,000 years ago found in a cave outside the village of Taforalt in northeastern Morocco. The people were part of what is called the Iberomaurusian culture.
Analysis of forms — or isotopes — of elements including carbon, nitrogen, zinc, sulfur and strontium in these remains indicated the type and amount of plants and meat they ate. Found at the site were remains from different edible wild plants including sweet acorns, pine nuts, pistachio, oats and legumes called pulses. The main prey, based on bones discovered at the cave, was a species called Barbary sheep.
“The prevailing notion has been that hunter-gatherers’ diets were primarily composed of animal proteins. However, the evidence from Taforalt demonstrates that plants constituted a big part of the hunter-gatherers’ menu,” said Zineb Moubtahij, a doctoral student in archaeology at the Max Planck Institute for Evolutionary Anthropology in Germany and lead author of the study published on Monday in the journal Nature Ecology & Evolution.
“It is important as it suggests that possibly several populations in the world already started to include substantial amount of plants in their diet” in the period before agriculture was developed, added archeogeochemist and study co-author Klervia Jaouen of the French research agency CNRS.
The Iberomaurusians were hunter-gatherers who inhabited parts of Morocco and Libya from around 25,000 to 11,000 years ago. Evidence indicates the cave served as a living space and burial site.
These people used the cave for significant portions of each year, suggesting a lifestyle more sedentary than simply roaming the landscape searching for resources, the researchers said. They exploited wild plants that ripened at different seasons of the year, while their dental cavities illustrated a reliance on starchy botanical species.
Edible plants may have been stored by the hunter-gatherers year-round to guard against seasonal shortages of prey and ensure a regular food supply, the researchers said.
These people ate only wild plants, the researchers found. The Iberomaurusians never developed agriculture, which came relatively late to North Africa.
“Interestingly, our findings showed minimal evidence of seafood or freshwater food consumption among these ancient groups. Additionally, it seems that these humans may have introduced wild plants into the diets of their infants at an earlier stage than previously believed,” Moubtahij said.
“Specifically, we focused on the transition from breastfeeding to solid foods in infants. Breast milk has a unique isotopic signature, distinct from the isotopic composition of solid foods typically consumed by adults.”
Two infants were among the seven people whose remains were studied. By comparing the chemical composition of an infant’s tooth, formed during the breastfeeding period, with the composition of bone tissue, which reflects the diet shortly before death, the researchers discerned changes in the baby’s diet over time. The evidence indicated the introduction of solid foods at around the age of 12 months, with babies weaned earlier than expected for a pre-agricultural society.
North Africa is a key region for studying Homo sapiens evolution and dispersal out of Africa.
“Understanding why some hunter-gatherer groups transitioned to agriculture while others did not can provide valuable insights into the drivers of agricultural innovation and the factors that influenced human societies’ decisions to adopt new subsistence strategies,” Moubtahij said.
Palestinian prisoner in Israel wins top fiction prize
- The mask in the novel’s title refers to the blue identity card that Nur, an archaeologist living in a refugee camp in Ramallah, finds in the pocket of an old coat belonging to an Israeli
ABU DHABI: Palestinian writer Basim Khandaqji, jailed 20 years ago in Israel, won a prestigious prize for Arabic fiction on Sunday for his novel “A Mask, the Color of the Sky.”
The award of the 2024 International Prize for Arabic Fiction was announced at a ceremony in Abu Dhabi.
The prize was accepted on Khandaqji’s behalf by Rana Idriss, owner of Dar Al-Adab, the book’s Lebanon-based publisher.
Khandaqji was born in the Israeli-occupied West Bank city of Nablus in 1983, and wrote short stories until his arrest in 2004 at the age of 21.
He was convicted and jailed on charges relating to a deadly bombing in Tel Aviv, and completed his university education from inside jail via the Internet.
The mask in the novel’s title refers to the blue identity card that Nur, an archaeologist living in a refugee camp in Ramallah, finds in the pocket of an old coat belonging to an Israeli.
Khandaqji’s book was chosen from 133 works submitted to the competition.
Nabil Suleiman, who chaired the jury, said the novel “dissects a complex, bitter reality of family fragmentation, displacement, genocide, and racism.”
Since being jailed Khandaqji has written poetry collections including “Rituals of the First Time” and “The Breath of a Nocturnal Poem.”
He has also written three earlier novels.
Mexican doctor claims victory in $28 Cartier earrings battle
MEXICO CITY: A Mexican man has claimed a victory over French luxury brand Cartier, saying an error allowed him to buy two pairs of earrings for $28 that were supposed to cost nearly $28,000.
After a four-month struggle, doctor Rogelio Villarreal said he had finally received the jewelry, which he accused the company of refusing to deliver after his online purchase in December.
According to Villarreal, he came across the low-priced earrings while browsing Instagram.
“I swear I broke out in a cold sweat,” he wrote on the social media platform X.
Cartier declined to recognize the purchase and offered Villarreal a refund, as well as a bottle of champagne and a passport holder as compensation, according to a company letter shared by the doctor.
But Villarreal refused and decided to take the case to Mexico’s consumer protection agency, which ruled in favor of the doctor.
Cartier accepted the decision, Villarreal announced.
“War is over. Cartier is complying,” he wrote.
French barber still trimming at 90
- “I love this job, it’s in my bones,” he said
- Even with arthritis, he is on his feet from Tuesday to Saturday, tending to his customers’ hair and beards in his shop in the small southern town of Saint-Girons
SAINT-GIRONS, France: French barber Roger Amilhastre, 90, could have hung up his clippers decades ago but he said his passion for hair gives him a reason to get up in the morning.
“I love this job, it’s in my bones,” he said, leaning on one of his cast-iron barber’s chairs from the 1940s.
“And despite my age, my hands still don’t shake.”
Even with arthritis, he is on his feet from Tuesday to Saturday, tending to his customers’ hair and beards in his shop in the small southern town of Saint-Girons in the foothills of the Pyrenees.
“I would have liked to retire at 60, but my wife was sick and I needed to pay for the care home,” he said, which cost more than 2,000 euros ($2,150) a month.
Even after his wife died in January, he kept going to work to stave off the sad thoughts.
“I’m not grumpy getting up” to go to work, he said.
France’s national hairdressers’ union believes Amilhastre may be France’s oldest active barber.
“We have a few who continue late in life, but 90 years old is exceptional,” union president Christophe Dore told AFP.
“I’m not sure if he is France’s oldest barber, but if not, he can’t be far off,” he added.
According to the national statistics institute INSEE, a little more than half a million people over 65 still work in France.
In the southern region of Occitanie, where Amilhastre lives, only 1.65 percent of people older than 70 years old still work, including 190 79-year-olds. But statistics do not go beyond that age.
Many of Amilhastre’s customers call him Achille, after his father who founded the barber’s shop in 1932, giving it his name and then teaching his son the profession.
The shop witnessed the German occupation of France during World War II.
“During the war, German police came to find my father to groom a captain who had broken his leg,” Amilhastre said.
German troops had taken over a large stately home in town called Beauregard.
“We were scared because they used to say that anyone who went up to Beauregard never came back,” he said.
“Luckily he did.”
The 90-year-old said he remembered a “tough period” for businesses when he first picked up the scissors in 1947 a few years after the war ended.
But then the town rebounded, he said, with its men following a flurry of new hair trends from greased back quiffs in the 1950s to 1970s bowl cuts.
The barber’s shop survived an economic downturn as local paper mills closed in the 1980s sparking mass layoffs, and supermarkets pushed small shops out of business.
“People started looking for work further afield, so we had to adapt and stay open later in the evening,” Amilhastre said.
That same decade, the AIDS epidemic sent customers into a worried frenzy.
“People were scared. They no longer asked to be shaved and when we did, we were petrified there’d be a cut, that someone would bleed and the virus would be passed on to the next customer,” he said.
Jean-Louis Surre, 67, runs the nearby cafe where Amilhastre once taught him to play billiards as a young boy.
Behind his bar, Surre said he still remembered his mother taking him across the road to see Amilhastre for a haircut every month as a child.
“He’d pump up the chair to reach the mirror, use his clippers and then at the end perfume you with some cologne — you know, squeezing those little pumps,” he said.
He is one of several old-timers to regularly drop by Achille’s — even just to read the newspaper or have a chat.
Inside the barber’s, Jean Laffitte, a balding 84-year-old, said he no longer really needed a haircut.
“With what little is left up there, these days I come out of friendship,” he said.
China’s Shenzhou-18 mission docks with space station
- The astronauts took off from the Jiuquan Satellite Launch Center in China’s northwest at 8:59 p.m. local time Thursday
- The astronauts will stay at the Tiangong space station for six months, carrying out experiments
JIUQUAN, China: A spaceship carrying three astronauts from China’s Shenzhou-18 mission safely docked at Tiangong space station Friday, state-run media reported, the latest step in Beijing’s space program that aims to send astronauts to the Moon by 2030.
The crew took off in a capsule atop a Long March-2F rocket from the Jiuquan Satellite Launch Center in China’s northwest at 8:59 p.m. local time 1259 GMT) Thursday.
By early Friday the spacecraft had “successfully docked” with the space station, state-run news agency Xinhua reported, citing the China Manned Space Agency.
The mission is led by Ye Guangfu, a fighter pilot and astronaut who was previously part of the Shenzhou-13 crew in 2021.
He is joined by astronauts Li Cong and Li Guangsu, who are heading into space for the first time.
Onlookers cheered as the rocket blasted off into the night sky, an AFP journalist at the scene said.
Xinhua said the launch had been declared a “complete success.”
The astronauts will stay at the Tiangong space station for six months.
There they plan to carry out experiments “in the fields of basic physics in microgravity, space material science, space life science, space medicine and space technology,” the China Manned Space Agency has said.
They will also try and create an aquarium onboard and seek to raise fish in zero gravity, according to Xinhua.
“Not only will the taikonauts find joy in the space ‘aquarium,’ but it may also pave the way for their future counterparts to enjoy nutritious fish from their own in-orbit harvests,” it added.
They will also conduct experiments on “fruit flies and mice,” a researcher quoted by the agency said.
The new crew will replace the Shenzhou-17 team, who were sent to the station in October.
Plans for China’s “space dream” have been put into overdrive under President Xi Jinping.
The world’s second-largest economy has pumped billions of dollars into its military-run space program in an effort to catch up with the United States and Russia.
Beijing also aims to send a crewed mission to the Moon by 2030, and plans to build a base on the lunar surface.
China has been effectively excluded from the International Space Station since 2011, when the United States banned NASA from engaging with the country — pushing Beijing to develop its own orbital outpost.
That station is the Tiangong, which means “heavenly palace” — the crown jewel of a space program that has landed robotic rovers on Mars and the Moon, and made China the third country to independently put humans in orbit.
It is constantly crewed by rotating teams of three astronauts, with construction completed in 2022.
The Tiangong is expected to remain in low Earth orbit at between 400 and 450 kilometers (250 and 280 miles) above the planet for at least 10 years.
