A daredevil billionaire rocketed back to space Tuesday, aiming to perform the first private spacewalk and venture farther than anyone since NASA's Apollo moonshots.

Unlike his previous chartered flight, tech entrepreneur Jared Isaacman shared the cost with SpaceX this time around, which included developing and testing brand new spacesuits to see how they'll hold up in the harsh vacuum.

If all goes as planned, it will be the first time private citizens conduct a spacewalk, but they won’t venture away from the capsule. Considered one of the most riskiest parts of spaceflight, spacewalks have been the sole realm of professional astronauts since the former Soviet Union popped open the hatch in 1965, closely followed by the US. Today, they are routinely done at the International Space Station.

Isaacman, along with a pair of SpaceX engineers and a former Air Force Thunderbirds pilot, launched before dawn aboard a SpaceX Falcon 9 rocket from Florida. The spacewalk is scheduled for late Wednesday or Thursday, midway through the five-day flight.

But first the passengers are shooting for way beyond the International Space Station — an altitude of 870 miles (1,400 kilometers), which would surpass the Earth-lapping record set during NASA’s Project Gemini in 1966. Only the 24 Apollo astronauts who flew to the moon have ventured farther.

The plan is to spend 10 hours at that height — filled with extreme radiation and riddled with debris — before reducing the oval-shaped orbit by half. Even at this lower 435 miles (700 kilometers), the orbit would eclipse the space station and even the Hubble Space Telescope, the highest shuttle astronauts flew.

All four wore SpaceX’s spacewalking suits because the entire Dragon capsule will be depressurized for the two-hour spacewalk, exposing everyone to the dangerous environment.

Isaacman and SpaceX's Sarah Gillis will take turns briefly popping out of the hatch. They’ll test their white and black-trimmed custom suits by twisting their bodies. Both will always have a hand or foot touching the capsule or attached support structure that resembles the top of a pool ladder. There will be no dangling at the end of their 12-foot (3.6-meter) tethers and no jetpack showboating. Only NASA’s suits at the space station come equipped with jetpacks, for emergency use only.

Pilot Scott “Kidd” Poteet and SpaceX’s Anna Menon will monitor the spacewalk from inside. Like SpaceX’s previous astronaut flights, this one will end with a splashdown off the Florida coast.

At a preflight news conference, Isaacman — CEO and founder of the credit card processing company Shift4 — refused to say how much he invested in the flight. “Not a chance,” he said.

SpaceX teamed up with Isaacman to pay for spacesuit development and associated costs, said William Gerstenmaier, a SpaceX vice president who once headed space mission operations for NASA.

“We’re really starting to push the frontiers with the private sector,” Gerstenmaier said.

It’s the first of three trips that Isaacman bought from Elon Musk 2 1/2 years ago, soon after returning from his first private SpaceX spaceflight in 2021. Isaacman bankrolled that tourist ride for an undisclosed sum, taking along contest winners and a childhood cancer survivor. The trip raised hundreds of millions for St. Jude Children’s Research Hospital.

Spacesuit development took longer than anticipated, delaying this first so-called Polaris Dawn flight until now. Training was extensive; Poteet said it rivaled anything he experienced during his Air Force flying career.

As SpaceX astronaut trainers, Gillis and Menon helped Isaacman and his previous team — as well as NASA’s professional crews — prepare for their rides.

“I wasn’t alive when humans walked on the moon. I’d certainly like my kids to see humans walking on the moon and Mars, and venturing out and exploring our solar system,” the 41-year-old Isaacman said before liftoff.

Poor weather caused a two-week delay. The crew needed favorable forecasts not only for launch, but for splashdown days later. With limited supplies and no ability to reach the space station, they had no choice but to wait for conditions to improve.

Heavy snowfall in Poland caused tailbacks stretching as far as 20 km (12.43 miles) on a motorway between ​the capital Warsaw and the Baltic port city of Gdansk during the night, police said on Wednesday.

While the situation left hundreds of people trapped in their cars in freezing conditions, by the early hours of ‌Wednesday morning traffic ‌was moving again, ‌according ⁠to ​police.

"The ‌difficult situation began yesterday after 4 p.m., when the first trucks on the S7 route... began having trouble approaching the slopes," said Tomasz Markowski, a spokesperson for police in the northern city of ⁠Olsztyn.

"This led to a traffic jam stretching approximately ‌20 kilometers overnight." Deputy Infrastructure Minister ‍Stanislaw Bukowiec ‍told a press conference that nobody had ‍been hurt as a result of the difficult situation on the roads.

Anna Karczewska, a spokesperson for police in Ostroda, said officers had ​tried to help drivers who found themselves stuck. Ostroda lies on ⁠the highway about 40 km west of Olsztyn.

"We helped as much as we could, and we had coffee and hot tea for the drivers, which the Ostroda City Hall had prepared for us," she said.

State news agency PAP reported that there had also been some disruption to railways and airports, ‌but that services were returning to normal.

Children exposed to high levels of screen time before age two showed changes in brain development that were linked to slower decision-making and increased anxiety by their teenage years, according to new study released by the Agency for Science, Technology and Research in Singapore.

Prepared in collaboration with the National University of Singapore (NUS) Yong Loo Lin School of Medicine, the study focuses on infancy, a period when brain development is most rapid and especially sensitive to environmental influences.

The amount and type of screen exposure in infancy are largely determined by parental and caregiver awareness and parenting practices, highlighting a critical window for early guidance and intervention, showed the study, published in eBioMedicine on Tuesday.

It said the researchers followed 168 children before age two and conducted brain scans at three time points (ages 4.5, 6, and 7.5), which allowed them to track how brain networks developed over time rather than relying on a single snapshot.

Children with higher infant screen time showed an accelerated maturation of brain networks responsible for visual processing and cognitive control.

The researchers suggest this may result from the intense sensory stimulation that screens provide. Notably, screen time measured at ages three and four did not show the same effects, underscoring why infancy is a particularly sensitive period.

The study showed that children with high screen exposure, the networks controlling vision and cognition specialized faster, before they had developed the efficient connections needed for complex thinking. This can limit flexibility and resilience, leaving the child less able to adapt later in life.

It said this premature specialization came at a cost: children with these altered brain networks took longer to make decisions during a cognitive task at age 8.5, suggesting reduced cognitive efficiency or flexibility.

Those with slower decision-making, in turn, reported higher anxiety symptoms at age 13. These findings suggest that screen exposure in infancy may have effects that extend well beyond early childhood, shaping brain development and behavior years later.

In a related study, the same team found that infant screen time is also associated with alterations in brain networks that govern emotional regulation — but that parent-child reading could counteract some of these brain changes.

Researchers found that their results give a biological explanation for why limiting screen time in the first two years is crucial.

“But it also highlights the importance of parental engagement, showing that parent-child activities, like reading together, can make a real difference,” said Asst Prof Tan Ai Peng, Clinician-Scientist at NUS, and the study's senior author.

The study concluded that children exposed to high levels of screen time before age two are exposed to endure adolescent mental health, particularly on cognitive performance and anxiety levels.

Indonesian authorities have raised the alert level for the Mount Bur Ni Telong volcano in the country’s westernmost province of Aceh to its second highest following a series of increased activity and volcanic earthquakes, official said Wednesday.

The 2,624-meter (8,600-foot) stratovolcano in Aceh's Bener Meriah regency recorded at least seven earthquakes on Tuesday evening that were felt about five kilometers (three miles) away, while seismographs also detected seven shallow volcanic earthquakes along with 14 deep quakes and two tectonic quakes, said Lana Saria, the acting head of the Geological Agency at Energy and Mineral Resources Ministry.

She said based on the results of visual and instrumental monitoring which show the occurrence of increased volcanic activity for Mount Bur Ni Telong, scientists raised the alert level from the third to the second highest level Tuesday evening.

“Aftershocks following local tectonic events indicate magma activity is easily triggered by tectonic disturbances,” Saria said, adding that the increase in seismic activity has been ongoing since July and became more intense and shallow in the past two months.

According to The Associated Press, the agency's visual monitoring showed the volcano clearly visible with no crater smoke. However, she warned of possible eruption, including phreatic blasts and hazardous volcanic gases near areas with fumaroles and solfataras, openings in the Earth’s crust that emit steam and gases.

Authorities urged residents and visitors to stay at least 4 kilometers (2.4 miles) from the crater and avoid fumarole and solfatara zones during cloudy or rainy weather because gas concentrations can be life-threatening.

The heightened alert came as the Bener Meriah area is still recovering from catastrophic floods and landslides earlier this month that struck 52 cities and regencies on Sumatra island, leaving 1,141 people dead with 163 residents still missing and more than 7,000 injured, the National Disaster Management Agency said. In Bener Meriah alone, 31 people died and 14 are still missing after the floods and landslides hit the regency, disrupting access to remote villages and displacing more than 2,100 residents.

Local media said people living in three villages within a 2-kilometer (1.2-mile) radius from the crater are being evacuated as officials fear that heavy rains combined with volcanic activity could worsen conditions and complicate evacuation efforts.

Indonesia, an archipelago of more than 280 million people, has over 120 active volcanoes. It is prone to volcanic activity because it sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
