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.

Daylight saving time, a practice affecting almost 400 million people across North America, is once again in the spotlight as debates over its necessity continue. This twice-a-year ritual of adjusting clocks forward in spring and back in autumn has been ingrained in American, Canadian and Cuban life for more than a century. However, recent legislative proposals and shifting public sentiment are prompting a reevaluation of its relevance in today's society, Reuters said.
WHEN DO THE CLOCKS CHANGE?
Daylight saving time in the US and some other countries ends on Nov. 3 at 2 a.m. local time, meaning people will gain an extra hour of sleep. Mornings will be brighter but it will get dark earlier in the evening. The saying "spring forward, fall back" serves as a helpful reminder for adjusting clocks.
In the UK and other European countries, daylight saving time, also known as summer time, ends on Oct. 27.
Daylight saving time always starts on the second Sunday in March and ends on the first Sunday in November in the United States. This contrasts with the UK and European Union, where summer time begins on the last Sunday in March and ends on the last Sunday in October.
WHEN IS THE SHORTEST DAY OF THE YEAR IN 2024?
The shortest day of 2024 will be on Dec. 21, which marks the winter solstice. Daylight hours vary significantly across latitudes in the Northern Hemisphere. Areas near the North Pole will be plunged into complete darkness while southern regions will still get over 10 hours of sunshine.
Next year, daylight saving time will start on March 9 and end on Nov. 2.
WHY WAS DAYLIGHT SAVING CREATED IN THE US AND HOW DID IT START?
The modern idea of changing the clocks with the seasons can be traced back to at least the late 19th century, when New Zealand entomologist George Hudson proposed it to conserve energy and extend summer daylight hours, something which would have benefited his own hobby of collecting insects after work. The idea was slow to gain traction until World War One, when European states sought any strategies to conserve fuel. Germany was the first country to adopt daylight saving time in 1916. The United States followed in 1918.
The practice went through many variations before the United States standardized it in 1966 in the Uniform Time Act, which allows states to opt out of it but not to stay on daylight saving time permanently.
WHY IS DAYLIGHT SAVING TIME CONTROVERSIAL?
A common myth is that the US adopted daylight saving time to benefit farmers, but in reality many farmers are opposed to the practice for being disruptive to their schedules. The original motivation to conserve fuel is also under debate, as studies have found little, if any, energy savings from the shift, according to the US Congressional Research Service. Opponents point to other studies that have found adverse health effects linked to daylight saving time, such as a spike in fatal traffic accidents, heart attacks, strokes and sleep deprivation in the days after clocks are moved forward an hour every March.
A March 2023 YouGov poll found that 62% of Americans want to end the practice of changing clocks, though only 50% preferred to keep permanent daylight saving time.
DO ALL US STATES OBSERVE DAYLIGHT SAVING TIME?
No. Hawaii and Arizona, with the exception of the Navajo Nation, do not observe daylight saving time. The US territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the US Virgin Islands also observe permanent standard time. While daylight saving time is widespread across the United States, 19 states have passed legislation to permanently use daylight saving time if Congress were to allow it, according to the National Conference of State Legislatures.
IS THE US ENDING DAYLIGHT SAVING TIME?
The United States is not ending daylight saving time any time soon, though there is proposed federal legislation called the Sunshine Protection Act that would make daylight saving time permanent. The legislation, introduced by a bipartisan group of senators, was passed by the Senate in 2022 but stalled in the US House of Representatives because lawmakers could not agree on whether to keep standard time or permanent daylight saving time.
The group of senators reintroduced the bill last year and it has been referred to the Committee on Commerce, Science and Transportation to review. The bill would need to pass the Senate and House before President Joe Biden could sign it into law.
