NASA astronauts Butch Wilmore and Suni Williams returned to Earth in a SpaceX capsule on Tuesday with a soft splashdown off Florida's coast, nine months after their faulty Boeing Starliner craft upended what was to be a week-long stay on the International Space Station.
Their return caps a protracted space mission that was fraught with uncertainty and technical troubles, turning a rare instance of NASA's contingency planning - and the latest failures of Starliner - into a global and political spectacle, Reuters reported.
Wilmore and Williams, two veteran NASA astronauts and retired US Navy test pilots, had launched into space as Starliner's first crew in June for what was expected to be an eight-day test mission. But issues with Starliner's propulsion system led to cascading delays to their return home, culminating in a NASA decision to fold them into its crew rotation schedule and return them on a SpaceX craft this year.
On Tuesday morning, Wilmore and Williams strapped inside their Crew Dragon spacecraft along with two other astronauts and undocked from the ISS at 1.05 a.m. ET (0505 GMT) to embark on a 17-hour trip to Earth.
The four-person crew, formally part of NASA's Crew-9 astronaut rotation mission, plunged through Earth's atmosphere, using its heatshield and two sets of parachutes to slow its orbital speed of 17,000 mph (27,359 kph) to a soft 17 mph at splashdown, which occurred at 5:57 p.m. ET some 50 miles off Florida's Gulf Coast under clear skies.
"What a ride," NASA astronaut Nick Hague, the Crew-9 mission commander inside the Dragon capsule, told mission control moments after splashing down. "I see a capsule full of grins, ear to ear."
The astronauts will be flown on a NASA plane to their crew quarters at the space agency's Johnson Space Center in Houston for a few days of routine health checks before NASA flight surgeons say they can go home to their families.
"They will get some well-deserved time off, well-deserved time with their families," NASA's Commercial Crew Program chief Steve Stich told reporters after the splashdown. "It's been a long time for them."
POLITICAL SPECTACLE
The mission captured the attention of US President Donald Trump, who upon taking office in January called for a quicker return of Wilmore and Williams and alleged, without evidence, that former President Joe Biden "abandoned" them on the ISS for political reasons.
NASA acted on Trump's demand by moving Crew-9's replacement mission up sooner, the agency's ISS chief Joel Montalbano said Tuesday. The agency had swapped a delayed SpaceX capsule for one that would be ready sooner and sped through its methodical safety review process to heed the president's call.
Trump told Fox News on Tuesday that Wilmore and Williams will visit the Oval Office after they recover from their mission.
Wilmore earlier this month told reporters on a call from the ISS that he did not believe NASA's decision to keep them on the ISS until Crew-10's arrival had been affected by politics under the Biden administration.
SpaceX CEO Elon Musk, a close adviser to Trump, had echoed Trump's call for an earlier return, adding the Biden administration spurned a SpaceX offer to provide a dedicated Dragon rescue mission last year.
NASA officials have said the two astronauts had to remain on the ISS to maintain adequate staffing levels and it did not have the budget or the operational need to send a dedicated rescue spacecraft. Crew Dragon flights cost between $100 million to $150 million.
Crew Dragon is the only US spacecraft capable of flying people in orbit. Boeing had hoped Starliner would compete with the SpaceX capsule before the mission with Wilmore and Williams threw its development future into uncertainty.
Stich said on Tuesday that Starliner might need to fly another uncrewed flight - which would be its third such mission and fourth test overall - before it routinely carries US astronauts.
Boeing, which congratulated the astronauts' return on X, did not respond immediately to a request for comment.
286 DAYS IN SPACE
The ISS, about 254 miles in altitude, is a football field-sized research lab that has been housed continuously by international crews of astronauts for nearly 25 years, a key platform of science diplomacy managed primarily by the US and Russia.
Swept up in NASA's routine astronaut rotation schedule, Wilmore and Williams worked on roughly 150 science experiments aboard the station until their replacement crew launched last week.
The pair logged 286 days in space on the mission - longer than the average six-month ISS mission length, but far short of US record holder Frank Rubio, whose 371 days in space ending in 2023 were the unexpected result of a coolant leak on a Russian spacecraft.
Living in space for months can affect the human body in multiple ways, from muscle atrophy to possible vision impairment.
Williams, capping her third spaceflight, has tallied 608 cumulative days in space, the second most for any US astronaut after Peggy Whitson's 675 days. Russian cosmonaut Oleg Kononenko set the world record last year at 878 cumulative days.
"We came prepared to stay long, even though we planned to stay short," Wilmore told reporters from space earlier this month.
"That's what your nation's human spaceflight program's all about," he said. "Planning for unknown, unexpected contingencies. And we did that."

Moon Race: How China is Challenging the US

Walking on the Moon by 2030, building a lunar base, and then perhaps on to Mars: after 30 years of honing its expertise, China is challenging the United States' supremacy in spaceflight.

As US space agency NASA prepares for its crewed lunar flyby mission, Artemis II, we take a look at China's ambitions in space:

- What is China's crewed program? -

China's crewed space program -- known as Project 921 -- was launched on September 21, 1992, aiming to develop its own expertise and space station.

The program has conducted around 15 crewed missions since the first flight of a Chinese astronaut, Yang Liwei, in 2003.

Blocked from the International Space Station (ISS) in 2011 by the United States, China built its own orbital hub.

The Tiangong, or "Heavenly Palace", space station welcomed its first occupants in 2021.

Three Chinese astronauts -- known as "taikonauts" -- are currently staying there.

The station allows China to accumulate crucial experience in spacewalks, docking, maintenance and effects on the body.

None of China's crewed launches have been fatal, and the program is following a long-term roadmap rather than a series of isolated projects.

"This effectiveness stems from strong political commitment at the highest level of the state, stable funding... and the integration of the entire industrial chain into the project," said Richard de Grijs, professor of physics and astronomy at Australia's Macquarie University.

"Compared to the Western, and particularly US, approach, where priorities can shift with each political cycle, this model offers clear advantages in terms of predictability and risk management," he told AFP.

While China's space program has been historically slower, "it won't change course at the whim of its leadership either".

- When will Chinese astronauts land on the Moon? -

The Chinese space agency (CNSA) hopes to put astronauts on the Moon by 2030.

China has already sent several robots to the Moon and brought back lunar samples.

But a crewed mission requires different equipment, which is currently being tested.

China is set to conduct a test flight of its new Mengzhou ("Dream Ship") spacecraft in 2026. Replacing the ageing Shenzhou, it will carry astronauts into lunar orbit.

Engineers are also developing a new ultra-powerful rocket around 90-metres (295-feet) long -- the Long March-10, essential for propelling the spacecraft to the Moon. It made its first low-altitude flight on February 11.

The Lanyue ("Seize the Moon") lander, which will transport the astronauts from orbit to the lunar surface, could also make its maiden flight between 2028 and 2029.

- Does China want a lunar base? -

China hopes to build a basic version of a crewed scientific base, called the International Lunar Research Station (ILRS), by 2035.

The base will be built near the Moon's south pole, where water in the form of ice is believed to be present.

China is collaborating with Russia on the project.

The base is expected to be built with bricks made on-site from lunar soil using 3D printers. Tested on Earth and on Tiangong, the technique is to be tested on the Moon during the uncrewed Chang'e-8 mission, scheduled for around 2028.

The CNSA says it wants to carry out archaeological research into the origin of the Moon, achieve breakthroughs in strategic technologies and exploit lunar resources.

An expanded version of the base is planned for around 2040.

China is also developing a constellation of relay satellites around the Moon to communicate between its far side and Earth.

- Is this a race with the United States? -

China never talks about a "Moon race" or competition with the United States.

"They are ambitious for the future of their program and see the Moon as the logical next step, for its own sake, not for any rivalry. I don't think it would change anything for them if America wasn't going," said Jonathan McDowell, astrophysicist and space analyst.

"Having said that," he added, "the establishment of a lunar base by China would be a real challenge to America's ability to establish such a base -- there's only a small amount of suitable area near the lunar south pole."

For now, China lags behind the United States in terms of crewed flights, according to Chen Lan, a specialist in the Chinese space program.

NASA's Dragon and Orion spacecraft remain superior compared to China's Shenzhou, he noted.

"However, I expect when China realizes manned lunar landing by 2030 with the new spaceship and lunar landing vehicle, it will catch up with the US in the human spaceflight field."

- Mars next? -

After 2040, the Chinese lunar base will be used to "validate technology and capabilities for a manned mission to Mars", according to the CNSA.

Chinese space manufacturing companies and scientists have previously pointed to the Red Planet as a potential destination for astronauts.

"But I don't think that there will be serious plans to Mars before completion of the lunar landing and the initial lunar base," Chen said.

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."
