A crew of four aboard a SpaceX capsule embarked on the world's first private spacewalk on Thursday, as an astronaut eased out of the Crew Dragon spacecraft on a tether into the vacuum of space, hundreds of miles from Earth.

Billionaire Jared Isaacman, 41, exited first about 6:52 a.m. ET (1052 GMT). After he returned a few minutes later, SpaceX engineer Sarah Gillis, 30, was scheduled to take her turn in space, all their maneuvers streaming live on the company's website, Reuters reported.

"Back at home we all have a lot of work to do, but from here, Earth sure looks like a perfect world," Isaacman said after emerging from the spacecraft, the planet glittering in half shadow below him.

Before the spacewalk began, the capsule was completely depressurized, with the whole crew relying on their slim, SpaceX-developed spacesuits for oxygen, provided via an umbilical connection to Crew Dragon.

The spacewalk was scheduled to last only about 30 minutes, but the procedures to prepare for it and to finish it safely last about two hours. It was meant to test the new spacesuit designs and procedures for the capsule, among other things.

Isaacman, Gillis, Scott Poteet, 50, a retired US Air Force lieutenant colonel, and SpaceX engineer Anna Menon, 38, had been orbiting Earth aboard Crew Dragon since Tuesday's pre-dawn launch from Florida of the Polaris Dawn mission. Menon and Poteet remained inside the spacecraft during the spacewalk.

It is the Elon Musk-led company's latest and riskiest bid to push the boundaries of commercial spaceflight.

Isaacman, a pilot and the billionaire founder of electronic payments company Shift4 (FOUR.N), opens new tab, is bankrolling the Polaris mission, as he did his Inspiration4 flight with SpaceX in 2021.

He has declined to say how much he is paying, but the missions are likely to cost hundreds of millions of dollars, based on Crew Dragon's price of roughly $55 million a seat for other flights.

-FARTHEST SINCE APOLLO

Throughout Wednesday, the craft circled Earth at least six times in an oval orbit as shallow as 190 km (118 miles) and stretching out as far as 1,400 km (870 miles), the farthest in space that humans have traveled since the last US Apollo mission in 1972.

The gumdrop-shaped spacecraft then began to lower its orbit into a peak 700-km (435-mile) position and adjust cabin pressure to ready for the spacewalk, formally called Extravehicular Activity (EVA), the Polaris program said on social media on Wednesday.

"The crew also spent a few hours demonstrating the suit’s pressurized mobility, verifying positions and accessibility in microgravity along with preparing the cabin for the EVA," it said.

Only government astronauts with several years of training have done spacewalks in the past.

There have been roughly 270 on the International Space Station (ISS) since it was set up in 2000, and 16 by Chinese astronauts on Beijing's Tiangong space station.

The Polaris crew has spent 2-1/2 years training with SpaceX mission simulations and "experiential learning" in challenging, uncomfortable environments, said Poteet.

A record 19 astronauts are now in orbit, after Russia's Soyuz MS-26 mission ferried two cosmonauts and a US astronaut to the International Space Station on Wednesday, taking its headcount to 12.

Three Chinese astronauts are aboard the Tiangong space station.

The first US spacewalk in 1965, aboard a Gemini capsule, used a similar procedure to the one planned for Polaris Dawn: the capsule was depressurized, the hatch opened, and a spacesuited astronaut ventured outside on a tether.

Since 2001, Crew Dragon, the only US vehicle capable of reliably putting humans in orbit and returning them to Earth, has flown more than a dozen astronaut missions, mainly for NASA.

The agency seeded development of the capsule under a program meant to establish commercial, privately-built US vehicles capable of ferrying astronauts with the ISS.

Also developed under that program was Boeing's Starliner capsule, but it is farther behind.

Starliner launched its first astronauts to the ISS in June in a troubled test mission that ended this month with the capsule returning empty, leaving its crew on the space station for a Crew Dragon capsule to fetch next year.

Armenia's Underground Salt Clinic at Center of Alternative Medicine Debate

A mining cage drops deep beneath the Armenian capital, carrying asthma patients in helmets down into a salt cave clinic -- an alternative treatment center whose future is now at risk.

State funding for the speleotherapy center in the Avan salt mine was recently cut as the small Caucasus nation rolls out a new universal healthcare system that does not cover alternative medicine.

The fate of the facility is a snapshot of a global debate over the effectiveness and role of alternative treatments in modern healthcare, a particularly pressing issue in developing countries, AFP said.

Speleotherapy -- where patients spend several hours a day in caves breathing mineral-rich underground air believed to reduce respiratory irritation -- has been practiced for decades in parts of Eastern Europe and the former Soviet Union.

At the bottom of the Avan salt mine, a dim tunnel carved from grey rock salt leads to the Soviet-era center.

"We are 235 meters (770 feet) underground, and yet this is a hospital," doctor Anush Voskanyan said as she guided visitors into a vast chamber illuminated by rows of electric lamps.

Opened in 1987 inside a former mine, the center spans about 4,000 square meters of tunnels converted into treatment and recreation areas. For decades, patients received therapy for free under the state's healthcare program.

But in 2019, Armenia's health ministry stopped financing the clinic, arguing that speleotherapy does not meet evidence-based medical standards required for public funding.

Annual patient numbers dropped from more than 300 to around 50.

"We struggle to pay salaries and cannot renew equipment that has not been replaced since opening," clinic director Gurgen Hakobyan told AFP, saying its future was "uncertain."

- Global strategy -

Globally, supporters of traditional or complementary remedies say they have been overlooked by Western medicine.

The World Health Organization's members have called for a global effort to build a solid evidence base, regulate practitioners and integrate treatments that are proven safe and effective.

Supporters of speleotherapy say the cave environment, free from dust and allergens and with a constant temperature of around 19-20C, helps ease symptoms of asthma and allergies.

Voskanyan, the doctor, said she had seen children make full recoveries after treatment.

But the scientific evidence remains limited.

"Since 1985, only two dissertations have been written on the subject," said Lamara Manukyan, chair of the Armenian Association of Internal Medicine.

"We lack statistics and large-scale research."

She said speleotherapy "helps conventional medicine ease a patient's condition" and should be considered a "complementary therapy rather than a standalone treatment."

- 'Salvation' -

Armenia's health ministry said its decision to stop the clinic's funding reflects broader healthcare priorities as the country transitions toward universal medical insurance.

"At this stage, priority is given to diseases with high mortality rates such as cancer and cardiovascular illnesses," ministry spokeswoman Mariam Tsatryan told AFP.

"Alternative and wellness treatments cannot be included in insurance coverage."

Many of the centers's patients -- and its doctors -- lament the decision to strip funding.

Armen Stepanyan, a 63-year-old engineer from Russia's Siberian city of Kemerovo, has travelled to Yerevan annually for more than a decade after developing severe asthma.

"I tried everything -- sanatoriums, treatments -- nothing helped," he said. "Here I felt improvement after the first course."

Supporters argue the center's significance extends beyond medicine.

Manukyan, the chair of the internal medicine association, described it as part of Armenia's tradition of natural therapies, including mineral springs and spa resorts.

"There is no reason to dismantle an existing structure and lose a valuable tradition."

The government, which holds a stake in the center, is trying to privatize its shares, raising hopes that private investment could preserve or repurpose it as a research or medical tourism center.

"It would be really sad if the clinic had to shut down because it simply ran out of funding," said Stepanyan, the patient.

"I realized this was my salvation. This is the only place where I see real results."

Hiker's Dog Lost in New Zealand Forest Rescued by Helicopter after Strangers Fund Search

When a hiker fell from a 55-meter (180-foot) waterfall in wild New Zealand bush, rescuers were forced to evacuate the badly hurt woman without her dog, which couldn't be found.

After strangers raised thousands of dollars for a search, border collie Molly was flown to safety by a helicopter pilot who was determined to reunite pet and owner.

A week earlier, an emergency rescue helicopter found the woman with bruises and lacerations after a fall at a rocky spot at the waterfall on the South Island’s West Coast. She was airlifted on March 24 but they were forced to leave without her pet, The Associated Press reported.

Molly was bedraggled and hungry when she was found Tuesday, just a few meters from the spot where the hiker had been lucky to survive.

“I contacted her in hospital and said I’d go for a look for it,” said Matt Newton, the owner-operator of Precision Helicopters New Zealand, which is based at Hokitika Gorge near the Arahura River where Molly went missing. “I went and looked for the dog several times and no avail.”

Unwilling to give up, Newton and his family launched a fundraiser to pay for more flying hours and advanced search gear. Offers of help and donations poured in, with strangers pledging more than 11,000 New Zealand dollars ($6,300) for a search.

It was enough to fund three more hours in a helicopter using thermal imaging equipment. On Tuesday, Newton took to the skies with a veterinary nurse, volunteer searchers and a dog named Bingo in a renewed search for Molly.

“We struck jackpot within about an hour,” he said. “As we made our way up the river, we could see the dog in the thermal and then we could visually see it.”

There had been no sign of Molly at the waterfall when Newton previously searched the spot, he said. It wasn’t clear if the dog had also fallen from the waterfall or if she had eventually made her way to the spot where her injured owner landed.

The helicopter dropped low enough for a volunteer to disembark with the rescue dog Bingo to help coax Molly to safety and keep her calm.

Newton thought the dog had survived by eating feral animals during her week in the wilderness.

“She knew what we were up to, I think,” he said. “She behaved real well. She didn’t run away and she was pleased to be rescued.”

The dog was in “surprisingly good condition,” the pilot said. He sent word back to the helicopter base, where other volunteers waited to take turns in the search. “Instead we just had a big barbecue and all had a cuddle with Molly."

Hours after the dog’s rescue, her owner, still battered from her fall, arrived for a tearful reunion.

“I think that’ll speed up her healing process somewhat,” Newton said. “Having your dog back, that’s for sure.”

Experts said Wednesday they were halting rescue efforts for a humpback whale struggling in shallow waters off the German coast and had given up hope for its survival.

The 13.5-metre (44-foot) animal has been floundering off Germany's Baltic Sea coast for more than a week, having first been spotted stuck on a sandbank on March 23 near the city of Luebeck.

The creature managed to free itself but then became stuck again several more times near the city of Wismar. Coverage of its struggle for survival has gripped much of the German public.

Experts had hoped the whale's odyssey would end with it finding its way back to its natural habitat in the Atlantic Ocean, AFP reported.

But on Wednesday scientist Burkard Baschek, who had taken part in the rescue efforts, told reporters: "We are convinced that the animal is going to die" near Wismar.

The whale's ordeal had severely weakened it, its breathing had become "very, very irregular" and it was exhibiting "virtually no" reaction to the presence of human beings, he added.

The chances of it freeing itself again were "very low" and any further rescue efforts would therefore "be pure animal cruelty".

Since it was spotted last week the whale had prompted a large-scale rescue operation involving firefighters, scientists and the maritime police.

"Now we have the task of giving him some peace," said Till Backhaus, the environment minister for the state of Mecklenburg-Western Pomerania.

The animal will now "have to depart this life," he said.

An exclusion zone of 500 metres will be put in place around the whale in order to avoid disturbing it.

The authorities have ruled out putting the whale to sleep, saying this would be too dangerous both for the whale itself and those taking part in the operation.

In the case of its death, Backhaus said it would be transferred ashore for investigations to determine the cause of death.
