NASA and SpaceX on Wednesday delayed the launch of a replacement crew of four astronauts to the International Space Station that would have set in motion the long-awaited homecoming of US astronauts Butch Wilmore and Suni Williams.
NASA had been set to launch a SpaceX rocket from Florida carrying a replacement crew for the International Space Station in a mission that would set up the return to Earth of Wilmore and Williams - stuck in space for nine months after a trip on Boeing's faulty Starliner.
The launch was called off due to a hydraulic system issue with a ground support clamp arm for the Falcon 9 rocket, Reuters quoted NASA as saying in a statement.
Launch teams are working to address the issue, it said in another statement.
NASA said it is now targeting a launch no earlier than 7:03 p.m. EDT (2303 GMT) Friday after mission managers put off a launch attempt on Thursday because of high winds and rain forecast in the flight path of Dragon.
With a Friday Crew-10 launch, the Crew-9 mission with astronauts Wilmore and Williams would depart the space station on Wednesday, March 19, it said.
The US space agency had moved up the mission by two weeks after President Donald Trump and his adviser Elon Musk, CEO of SpaceX, called for Wilmore and Williams to be brought back earlier than NASA had planned.
A planned eight-day stay on the orbiting station has dragged on for Wilmore and Williams, both veteran astronauts and US Navy test pilots. Starliner returned to Earth without them last year.
SpaceX's rocket had been scheduled to blast off from the Kennedy Space Center in Cape Canaveral at 7:48 p.m. ET (2348 GMT) with a crew of two US astronauts and one astronaut each from Japan and Russia.
Wilmore and Williams have been working on research and maintenance with the space station's other astronauts and have remained safe, according to NASA. Williams told reporters in a March 4 call that she is looking forward to seeing her family and dogs upon returning home.
"It's been a roller coaster for them, probably a little bit more so than for us," Williams said of her family. "We're here, we have a mission - we're just doing what we do every day, and every day is interesting because we're up in space and it's a lot of fun."
The flight, known as Crew-10, normally would be considered a routine astronaut rotation. Instead, it has become entangled in politics as Trump and Musk have sought - without offering evidence - to blame former President Joe Biden for the delayed return of Wilmore and Williams.
The demands by Trump and Musk for an earlier return were an unusual intervention in NASA's human spaceflight operations. The mission previously had a target date of March 26, but NASA swapped a delayed SpaceX capsule with a different one that would be ready sooner.
When the new crew arrives aboard the station, Wilmore, Williams and two others - NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov - can return to Earth in a capsule that has been attached to the station since September, as part of the prior Crew-9 mission.
Wilmore and Williams cannot leave until the new Crew-10 craft arrives so that the ISS staffed with enough US astronauts for maintenance, according to NASA.
Wilmore and Williams flew to the station in June as the first test crew of Boeing's Starliner, which suffered propulsion system issues in space. NASA deemed it too risky for the astronauts to fly home on the Boeing craft. This led to the current plan to bring them home in a SpaceX capsule.

The veterinary staff at a Florida sea turtle hospital is getting help from space to monitor the animals they have rehabilitated. They're particularly interested in amputees.

Using satellite tracking devices in a collaboration between the Loggerhead Marinelife Center and the Smithsonian Conservation Biology Institute, scientists are learning how well sea turtles can survive in the wild after losing a limb.

Amelie, a Kemp's ridley sea turtle who lost her right forelimb to a predator — most likely a shark, the center said — was taken to the beach on Wednesday for her highly anticipated release. The turtle paused for about 30 seconds, then slowly made her way into the Atlantic Ocean as onlookers cheered.

Amelie had been rescued and brought to the center by the Inwater Research Group in Port St. Lucie, Florida, seven weeks earlier after a traumatic amputation. She underwent surgery to clean and close the wound, and was treated for pneumonia while in a tank at the center.

When veterinarians deemed her healthy enough to return to the sea, they glued a tracking device to her shell.

An ultrasound confirmed that Amelie is developing eggs, giving researchers another reason to track her movements.

Kemp's ridley turtles, the rarest of sea turtle species, are more typically found on Florida's Gulf Coast, so treating Amelie was especially significant, said Andy Dehart, the center's president and CEO.

Amelie is actually the fourth amputee sea turtle being tracked by the enter, Loggerhead research director Sarah Hirsch said. They include a three-limbed turtle named Pyari who has traveled nearly 700 miles since her release in January, her tracker shows.

“We do know that they can be successful in the wild because we have seen them on our nesting beaches, but we really want to understand their dive behaviors, how they’re migrating once they’re back in the wild," The Associated Press quoted Hirsch as saying.

The satellite tags have a saltwater switch that detects when the turtle comes up to the surface to breathe, triggering the transmission of data to the satellites. Their location appears online after a 24-hour delay. To view Amelie and other turtles tracked for various research projects, visit the Loggerhead website.

“They’ve been through a lot," Hirsch said. "They’ve gotten a lot of medical care here, and to see them be able to go back out and contribute to the population is really rewarding.”

Dogs have been loyal companions to people since we made them our first domesticated animals, descending long ago from gray wolves - though precisely when, where and why have remained unanswered. New genetic research now is offering valuable insight, including identifying the earliest-known dog, dating to 15,800 years ago, Reuters reported.

This dog, known from bones found at the Pinarbasi rock shelter site in Türkiye used by ancient human hunter-gatherers, is about 5,000 years older than the previous earliest-known, genetically confirmed canine, the researchers said.

The date of the Pinarbasi dog and several others almost as old identified at other sites in Europe shows that dogs already were widely distributed and an integral part of human culture millennia before the advent of agriculture, they said.

The new findings were presented in two scientific papers published on Wednesday in the journal Nature.

William Marsh, a postdoctoral researcher in the Ancient Genomics Laboratory at the Francis Crick Institute in London who was co-lead author of one of the studies, said the DNA evidence suggests dogs were present in various locales in western Eurasia by 18,000 years ago and already ⁠were quite different ⁠genetically from wolves.

"We putatively predict that dog and wolf populations diverged a lot earlier, likely before the last glacial maximum (of the Ice Age), so before 24,000 years ago. Although saying that, there is still a great degree of uncertainty," Marsh said.

The dog, descended from an ancient wolf population separate from modern wolves, was the first animal domesticated by people, with animals such as goats, sheep, cattle and cats coming later.

"Dogs have been by our side as humans underwent major lifestyle transitions and complex societies emerged," said geneticist Anders Bergström of the University of East Anglia in England, lead author of the other study.

"I think it's also interesting that, unlike most ⁠other domesticated animals, dogs do not always have very clearly defined roles or purposes for humans. Perhaps their primary role is often just to provide companionship," Bergström said.

Bergström and his team performed a large-scale search for the early dogs of Europe, using a new method to differentiate genetically between wolves and dogs among 216 ancient remains ranging from 46,000 to 2,000 years old from Belgium, Denmark, France, Germany, the Netherlands, Scotland, Sweden, Switzerland and Türkiye. This was the largest study of such remains to date.

The researchers managed to identify 46 dogs and 95 wolves. Because the skeletons of dogs and wolves were so similar in the early stages of canine domestication, genetic studies are needed to distinguish between them in ancient remains.

The oldest of the dogs identified by Bergström's team was one dating to 14,200 years ago from Switzerland's Kesslerloch Cave site. The oldest of the European dogs identified in this study were found to have shared an origin with dogs in Asia and the rest of the world, showing that ⁠these various canine populations did not ⁠arise from separate domestication events.

The Pinarbasi dog, identified in the study Marsh worked on, showed how much dogs were valued by the hunter-gatherers who kept them.

"At Pinarbasi, we have both human and dog burials, with dogs buried alongside humans," Marsh said.

There also was evidence that the people at Pinarbasi fed their dogs fish.

This study identified five dogs dating to between 15,800 and 14,300 years ago, including canine remains from Gough's Cave near Cheddar in England.

"At Gough's Cave, we have butchering and processing of humans after death that included cannibalism, as a funerary behavior akin to burial. Similar post-mortem modification, albeit not definitively for consumption, was found on the dog remains," Marsh said.

The Pinarbasi and Gough's Cave dogs were found to be more closely related to the ancestors of present-day European and Middle Eastern breeds such as boxers and salukis than to Arctic breeds like Siberian huskies.

Beyond companionship, the ancient dogs may have helped people hunt or perhaps served as watchdogs, sort of Ice Age alarm systems, according to the researchers. Unlike the many exotic dog breeds around today, these early dogs still likely closely resembled the wolves from which they descended, they said.

"The questions of when, where and why people domesticated dogs still remain largely unanswered," Bergström said. "We think it probably happened somewhere in Asia, but more precisely remains to be determined."

An Australian dog credited with saving over 100 koalas from bushfires is retiring after a decade of service.

Bear, an 11-year-old Australian Koolie, was one of the first dogs in the country to be trained on the scent of koala fur.

The International Fund for Animal Welfare called using dogs to detect koalas a "novel" approach.

"No one knew if it could be done," IFAW head of programs Josey Sharrad wrote in a statement about Bear on Monday.

As a pup, the four-legged hero's boundless energy made it tough to stay indoors, but he found his true potential in the bush.

"He literally went from chewing the walls of a Gold Coast apartment to roaming through the Aussie bush on a mission to save our most iconic species," Sharrad said.

Bear's skills saved over 100 koalas as the Black Summer bushfires raged across Australia's eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

The tail-wagging detective with a "joyful and goofy" personality retires with an extensive list of accolades, including an Animal of the Year award and Puppy Tales Photos Australian Dog of the Year award.

He also features in a "dogumentary" called "Bear: Koala Hero", and in a book, "Bear to the Rescue".

Bear will embark on a slower-paced chapter on the Sunshine Coast with one of his former handlers, getting belly rubs and playing his favorite game, fetch.

One of his former handlers, Romane Cristescu, said Bear had been a "tireless ambassador for koalas for a decade".

"He melted hearts all around the world, and opened many doors so we could have critical and difficult conversations about climate change and its impacts on the threatened koalas, as well as so many other species."
