It was delayed by around four hours earlier this morning – with no explanation given – before final safety checks of the spacesuits and equipment were carried out and SpaceX officials confirmed the mission was “go for spacewalk”.
First images broadcast from inside the Dragon capsule showed the four-strong crew preparing for the historic event – and sharing fist bumps with each other.
Daredevil Jared Isaacman, 41, was the first to exit the capsule – joining a small, elite group of spacewalkers who until today had included only professional astronauts.
After opening the hatch, a body camera showed his ascent through the narrow opening before incredible footage showed the spacewalk taking place to huge cheers from mission control at Cape Canaveral.
“It’s gorgeous,” he said, in awe of what he could see, as he eased out of the spacecraft into the vacuum of space, hundreds of miles from Earth.
He kept a hand or foot attached to the capsule the whole time as he flexed his arms and legs to see how the new spacesuit held up.

“The handsfree demonstration is very comparable to the trainer, in terms of the foot restraint,” he added, as he tested his spacesuit.
He had said before lift-off earlier this week: “Whatever risk is associated with it, it is worth it.”
“I wasn’t alive when humans walked on the moon,” he said. “I’d certainly like my kids to see humans walking on the moon and Mars, and venturing out and exploring our solar system.”
The tech entrepreneur blasted into space from Cape Canaveral in Florida before dawn on board a SpaceX Falcon 9 rocket on Tuesday for the five-day flight – along with mission pilot Scott Poteet, 50, a retired US Air Force lieutenant colonel, and SpaceX employees Sarah Gillis, 30, and Anna Menon, 38, both senior engineers at the company.
Ms Gillis followed Mr Isaacman out of the capsule on Thursday to carry out the same mobility tests.
The pair bobbed up and down in weightlessness, no higher than their knees out of the capsule.
The mission, called Polaris Dawn, to test a new line of spacesuits is the Elon Musk-led company’s riskiest mission yet – from a space capsule that doesn’t have a safety airlock, and in suits far slimmer than the bulky protective layers worn by NASA astronauts.
It is the first of three funded by Mr Isaacman – a pilot and the billionaire founder of electronic payment company Shift4.
He has refused to say how much he is paying for the missions, but they are believed to have cost hundreds of millions of dollars based on Crew Dragon’s roughly $55m (£42m) per-seat price for other flights.

Ms Gillis could be heard saying “pretty good” as she carried out her spacewalk – before she followed Mr Isaacman back into the capsule, after being told what sounded like she had less than six minutes of oxygen supply left.
“Pressure indicates good seal,” mission control told the astronauts, reassuringly, as the hatch was shut again.
“That was really cool,” said one of the presenters on the SpaceX live stream.
Mr Menon and Mr Poteet remained inside the spacecraft during the spacewalk.
Only government astronauts with several years of training have done spacewalks in the past.
There have been around 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 Atlantic hurricane season got off to a slow start this year, but there have now been 13 named storms – and there could be even more to come.
Back in May, the National Oceanic and Atmospheric Administration (NOAA) warned that this year’s season – running from 1 June to 30 November – had an 85% chance of being more active than usual.
An average year will see a total of 14 named storms, of which seven will be regular hurricanes and three will be major ones.
After a slow start – the slowest in 10 years – things have picked up recently. Of the 13 named storms, nine became hurricanes, with four reaching major hurricane status (rated category 3 and above on the Saffir-Simpson scale).

The science behind Hurricane Milton
August was unusually quiet, likely due to thunderstorm activity over Africa being further north than usual, but things picked up through September and early October.

We are past the peak of the season but there are more than six weeks left – so there is still time for more hurricanes to form.
And people in Florida know all too well the chance of hurricanes arriving later in the year.

In 2005, Hurricane Wilma hit towards the end of October, causing 30 deaths and around $19bn (£14.5bn) worth of damage.
With sea surface temperatures still above average, there’s a real chance of more hurricanes this season.
But that doesn’t mean any that do form will have an impact on land or Florida itself, in fact, Hurricane Leslie is currently in the central Atlantic not affecting any land masses.
And although major hurricanes can occur in November, they are rare. All we can do is wait and see.
I’ve spent the day driving north along Florida’s west coast from Fort Myers.
The coastline from Fort Myers to Tampa and a little beyond was all part of an evacuation zone as the authorities warned of a once-in-a-generation storm and the meteorologists tried to determine where it would hit.
Milton was, meteorologists said, behaving very unusually. That worried them. It also wobbled north and south as it approached the coastline overnight, compounding the concern.
The only encouraging news overnight was that it reduced in intensity from a category 5 down to a category 3. That lessened the impact from wind but not the concerns over a storm surge of water engulfing low-lying areas.
We stopped first at Punta Gorda where boats were overturned in the marina but there was no major structural damage. They dodged the bullet here.
Further north, the coastal highway passes Venice. There we found the streets littered with foliage from the palm trees, tiles ripped from roofs and billboards down but again, no major damage.

Lieutenant Dan safe and well after Hurricane
On foot we joined the National Guard and the local sheriff as they went house-to-house checking for anyone who may have tried to sit it out.
The storm surge here entered the houses but locals we spoke to guessed that it was only a foot or two high. Much lower than they had feared, about the same as the surge from Hurricane Helene two weeks ago and a huge relief for them.
Checking the major bridges for structural damage is important but the authorities had opened the Sunshine Skyway Bridge leading north to St Petersburg by the time I arrived.
The focus in St Petersburg itself is the Tropicana Field stadium. Home to Major League Baseball’s Tampa Bay Rays, it was being used to house emergency workers but the soft roof was ripped off in the storm.
All in all, the west coast of Florida has been very lucky. This is in part because so many followed the advice and evacuated.

Florida escapes worst of hurricane
Of course, the danger is that people may feel the warnings were overblown. The mayor of Tampa warned people that they would die if they stayed. Over the top? People did stay and they didn’t die. We spoke to people who said it was all exaggerated – politicians and media to blame as usual.
I do wonder if the massive pre-storm warnings this time are in part an over-correction by the Biden administration following the remarkable disinformation campaign from Donald Trump and his cohort.
He has spent the past few weeks since Hurricane Helene claiming that the federal authority has been hindering rescue and recovery efforts, contrary to fact.
And his surrogate, Georgia congresswoman Marjorie Taylor Greene, wrote on social media: “Yes they can control the weather,” adding “It’s ridiculous for anyone to lie and say it can’t be done.” It is not clear quite who “they” is.
The FEMA Administrator said the conspiracies were “absolutely the worst I have ever seen”.
Hurricane Milton could have been huge, yes, and given this barrage of conspiracy theories, especially about the authorities failing during Helene, they absolutely had to be prepared (over-prepared?) for this.
The hurricane was not the storm people feared. But the storm of American politics is just getting going. Less than a month until the election.
One person has been killed and 12 are trapped about 300m (1,000ft) underground at a former Colorado gold mine that’s now a tourist attraction.
It happened around noon on Thursday when a lift failed at Mollie Kathleen Gold Mine attraction in Cripple Creek.
Rescuers are trying to repair the elevator to bring the trapped people back to the surface.
With one group already below ground, the lift had a mechanical fault with another group inside as it was about halfway down the mineshaft, said Teller County Sheriff Jason Mikesell.
The incident killed one person – although it’s not been revealed how they died – and four others suffered minor injuries.
That group was able to return to the surface but the lift is out of commission until the problem is identified and fixed.
Radio communication with the trapped group – 11 tourists and their guide – is working and they have water, blankets and chairs, said the sheriff.

He said they hadn’t been told someone had died, only that there’s a problem with the lift.
Firefighters are on standby for a rescue operation if the fault can’t be fixed.

“If we have to, we can bring people up on those ropes, but it also subjects those first responders now to the threat and endangerment of doing so,” said Mr Mikesell.
The former mine is about 110 miles (180km) south of Denver and has been operating tours for 50 years.
