CAPE CANAVERAL, Florida: Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient water world, scientists reported Wednesday.
The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start.
“That’s the kind of environment that could have been essential to the steps that lead from elements to life,” said the Smithsonian Institution’s Tim McCoy, one of the lead study authors.
NASA’s Osiris-Rex spacecraft returned 122 grams (4 ounces) of dust and pebbles from the near-Earth asteroid Bennu, delivering the sample canister to the Utah desert in 2023 before swooping off after another space rock. It remains the biggest cosmic haul from beyond the moon. The two previous asteroid sample missions, by Japan, yielded considerably less material.
Small amounts of Bennu’s precious black grains — leftovers from the solar system’s formation 4.5 billion years ago — were doled out to the two separate research teams whose studies appeared in the journals Nature and Nature Astronomy. But it was more than enough to tease out the sodium-rich minerals and confirm the presence of amino acids, nitrogen in the form of ammonia and even parts of the genetic code.
Some if not all of the delicate salts found at Bennu — similar to what’s in the dry lakebeds of California’s Mojave Desert and Africa’s Sahara — would be stripped away if present in falling meteorites.
“This discovery was only possible by analyzing samples that were collected directly from the asteroid then carefully preserved back on Earth,” the Institute of Science Tokyo’s Yasuhito Sekine, who was not involved in the studies, said in an accompanying editorial.
Combining the ingredients of life with an environment of sodium-rich salt water, or brines, “that’s really the pathway to life,” said McCoy, the National Museum of Natural History’s curator of meteorites. “These processes probably occurred much earlier and were much more widespread than we had thought before.”
NASA’s Daniel Glavin said one of the biggest surprises was the relatively high abundance of nitrogen, including ammonia. While all of the organic molecules found in the Bennu samples have been identified before in meteorites, Glavin said the ones from Bennu are valid — “real extraterrestrial organic material formed in space and not a result of contamination from Earth.”
Bennu — a rubble pile just one-third of a mile (one-half of a kilometer) across — was originally part of a much larger asteroid that got clobbered by other space rocks. The latest results suggest this parent body had an extensive underground network of lakes or even oceans, and that the water evaporated away, leaving behind the salty clues.
Sixty labs around the world are analyzing bits of Bennu as part of initial studies, said the University of Arizona’s Dante Lauretta, the mission’s chief scientist who took part in both studies.
Most of the $1 billion mission’s cache has been set aside for future analysis. Scientists stress more testing is needed to better understand the Bennu samples, as well as more asteroid and comet sample returns. China plans to launch an asteroid sample return mission this year.
Many are pushing for a mission to collect rocks and dirt from the potentially waterlogged dwarf planet Ceres in the main asteroid belt. Jupiter’s moon Europa and Saturn’s moon Enceladus also beckon as enticing water worlds. Meanwhile, NASA has core samples awaiting pickup at Mars, but their delivery is on hold while the space agency studies the quickest and cheapest way to get them here.
“Are we alone?” McCoy said. “That’s one of the questions we’re trying to answer.”

Police video shows Vince McMahon’s 100 mph car crash in Connecticut
Newly released police video shows former WWE executive Vince McMahon ram his luxury sportscar into the rear end of another vehicle on a Connecticut highway last summer as he was being followed by a state trooper.
McMahon, now 80, was driving his 2024 Bentley Continental GT at more than 100 mph on the Merritt Parkway when he crashed in the town of Westport, according to state police.
A trooper’s dashcam video shows McMahon accelerating away, then braking too late to avoid crashing into the back of a BMW. The Bentley then swerves into a guardrail and careens back across the highway, creating a cloud of dirt and car parts.
“Why were you driving all over 100 mph?” state police Detective Maxwell Robins asked McMahon after catching up to the wrecked Bentley, which can cost over $300,000.
“I got my granddaughter’s birthday” McMahon replied, explaining he was on his way to see her. The encounter was recorded on police bodycam video.
No one was seriously injured in the July 24 crash, which happened the same day that WWE legend Hulk Hogan died of a heart attack in Florida.
Besides damage to the rear of the BMW, another vehicle driving on the opposite side of the parkway was struck by flying debris. The driver of that third car happened to be wearing a WWE shirt, according to the police video.
McMahon was cited for reckless driving and following too closely. A state judge in October allowed McMahon to enter a pretrial probation program that will result in the charges being erased from his record next October if he successfully completes the program. He was also ordered to make a $1,000 charitable contribution.
McMahon’s lawyer, Mark Sherman, said the crash was just an accident.
“Not every car accident is a crime,” Sherman said. “Vince’s primary concern during this case was for the other drivers and is appreciative that the court saw this more of an accident than a crime that needed to be prosecuted.”
State police said Robins was trying to catch up to McMahon on the parkway and clock his speed before pulling him over. They said the incident was not a pursuit, which happens when police chase someone trying to flee officers. They also said it did not appear McMahon was trying to escape — though in the video the detective suggests otherwise.
“I’m trying to catch up to you and you keep taking off,” Robins says.
“No, no no. I’m not trying to outrun you,” McMahon says.
An accident information summary provided to the media shortly after the crash did not mention that a trooper was following McMahon.
The Associated Press obtained the videos Wednesday through a public records request. They were first obtained by The Sun newspaper.
The trooper’s bodycam video also shows him asking McMahon whether he was looking at his phone when the crash happened. McMahon said he was not and adds that he hadn’t driven his car in a long time.
After Robins tells McMahon that his car is fast, McMahon replies, “Yeah, too fast.”
The videos also show McMahon talking to the driver he rear-ended. Barbara Doran, of New York City, told the AP last summer that McMahon expressed his concern for her and was glad she was OK. She said she was heading to a ferry to Martha’s Vineyard at the time of the crash.
After McMahon was given the traffic summons, he shook hands with Robins and another trooper and they wished him well.
McMahon stepped down as WWE’s CEO in 2022 amid a company investigation into sexual misconduct allegations. He also resigned as executive chairman of the board of directors of TKO Group Holdings, the parent company of WWE, in 2024, a day after a former WWE employee filed a sexual abuse lawsuit against him. McMahon has denied the allegations. The lawsuit remains pending.
McMahon bought what was then the World Wrestling Federation in 1982 and transformed it from a regional wrestling company into a worldwide phenomenon. Besides running the company with his wife, Linda, who is now the US education secretary, he also performed at WWE events as himself.
