A billionaire spacewalker returned to Earth with his crew on Sunday, ending a five-day trip that lifted them higher than anyone has traveled since NASA’s moonwalkers.

SpaceX’s capsule splashed down in the Gulf of Mexico near Florida's Dry Tortugas in the predawn darkness, carrying tech entrepreneur Jared Isaacman, two SpaceX engineers and a former Air Force Thunderbird pilot.

They pulled off the first private spacewalk while orbiting nearly 460 miles (740 kilometers) above Earth, higher than the International Space Station and Hubble Space Telescope. Their spacecraft hit a peak altitude of 875 miles (1,408 kilometers) following Tuesday’s liftoff.

Isaacman became only the 264th person to perform a spacewalk since the former Soviet Union scored the first in 1965, and SpaceX’s Sarah Gillis the 265th. Until now, all spacewalks were done by professional astronauts.

During Thursday's commercial spacewalk, the Dragon capsule’s hatch was open barely a half-hour. Isaacman emerged only up to his waist to briefly test SpaceX’s brand new spacesuit followed by Gillis, who was knee high as she flexed her arms and legs for several minutes. Gillis, a classically trained violinist, also held a performance in orbit earlier in the week.

The spacewalk lasted less than two hours, considerably shorter than those at the International Space Station. Most of that time was needed to depressurize the entire capsule and then restore the cabin air. Even SpaceX's Anna Menon and Scott “Kidd” Poteet, who remained strapped in, wore spacesuits.

SpaceX considers the brief exercise a starting point to test spacesuit technology for future, longer missions to Mars.

This was Isaacman’s second chartered flight with SpaceX, with two more still ahead under his personally financed space exploration program named Polaris after the North Star. He paid an undisclosed sum for his first spaceflight in 2021, taking along contest winners and a pediatric cancer survivor while raising more than $250 million for St. Jude Children’s Research Hospital.

For the just completed so-called Polaris Dawn mission, the founder and CEO of the Shift4 credit card-processing company shared the cost with SpaceX. Isaacman won’t divulge how much he spent.



Europe's Oldest Lake Settlement Uncovered in Albania

Archaeologists working on the shores of Ohrid Lake in Albania are convinced they have uncovered the oldest human settlement built on a European lake, finding evidence of an organized hunting and farming community living up to 8,000 years ago. The team, from Switzerland and Albania, spends hours each day about three meters (9.8 feet) underwater, painstakingly retrieving wooden stilts that supported houses.

The are also collecting bones of domesticated and wild animals, copper objects and ceramics, featuring detailed carvings.

Albert Hafner, from the University of Bern, said similar settlements have been found in Alpine and Mediterranean regions, but the settlements in the village of Lin are half a millennium older, dating back between 6,000 and 8,000 years.

"Because it is under water, the organic material is well-preserved and this allows us to find out what these people have been eating, what they have been planting," Hafner said.

Multiple studies show that Lake Ohrid, shared by North Macedonia and Albania, is the oldest lake in Europe, at over one million years.

The age of the findings is determined through radiocarbon dating and dendrochronology, which measures annual growth rings in trees. More than one thousand wood samples have been collected from the site, which may have hosted several hundred people.

It is believed to cover around six hectares, but so far, only about 1% has been excavated after six years of work.

Hafner said findings show that people who lived on the lake helped to spread agriculture and livestock to other parts of Europe.

"They were still doing hunting and collecting things but the stable income for the nutrition was coming from the agriculture," he said.

Albanian archaeologist Adrian Anastasi said it could take decades to fully explore the area.

"(By) the way they had lived, eaten, hunted, fished and by the way the architecture was used to build their settlement we can say they were very smart for that time," Anastasi said.
