SpaceX has blasted off a crew of four private astronauts for the first-ever private spacewalk.
A billionaire entrepreneur, a retired military fighter pilot and two SpaceX employees are using the company’s new spacesuits and a redesigned spacecraft for the mission which launched on Tuesday morning from the Kennedy Space Center in Florida.
It is the riskiest private space mission so far – only highly trained, well-funded government astronauts have done spacewalks in the past.
An attempt to launch last month was postponed hours before lift-off over a small helium leak in ground equipment on SpaceX’s launchpad.
The company fixed the leak, but its Falcon 9 was then grounded by US regulators over a booster recovery failure during an unrelated mission, further delaying the Polaris launch.
Risky Polaris mission is neccesary if Musk wants a city on Mars
Astronauts need courage, and never more so than on the Polaris Dawn mission now in orbit around the Earth.
The four crew members are all civilians. Only one has ever been to space before. Just once.
And if that wasn’t enough, the SpaceX Dragon capsule will take them further from Earth than anybody since the Apollo missions, through radiation belts around the planet.
Then the crew will attempt the first spacewalk by private astronauts, testing a new suit in the vacuum of space, from a spacecraft that doesn’t even have an airlock.
The mission is so full of risk it’s a wonder it ever got insurance.
Jared Isaacman, the billionaire commander and funder of the mission, is a space geek.
He believes in humanity’s journey away from our home planet. And the experiments and proof of technology on this flight are part of that.
Isaacman has paid SpaceX for three Polaris missions. He hopes the third will be on Starship, the mega-rocket that Elon Musk hopes will take people to Mars.
He said recently that uncrewed flights should happen in two years.
If they land successfully, astronauts will be on board two years after that and a self-sustaining city will exist on Mars in 20 years.
It sounds far-fetched.
But daring missions like Polaris could make it more likely.
“Crew safety is absolutely paramount and this mission carries more risk than usual, as it will be the furthest humans have travelled from Earth since Apollo and the first commercial spacewalk!,” Elon Musk, SpaceX’s chief executive, wrote about the mission last month on his social media site X.

There have been roughly 270 spacewalks on the International Space Station (ISS) since its creation in 2000, and 16 by Chinese astronauts on Beijing’s Tiangong space station.
The SpaceX mission, called Polaris Dawn, will last about five days in an oval-shaped orbit that passes as close to Earth as 190km (118 miles) and as far as 1,400km (870 miles), the furthest any humans will have travelled since the end of the United States’s Apollo moon programme in 1972.

Now the spacecraft has launched, it will begin a “two-day pre-breathe process” to prepare the crew for their upcoming spacewalk on Thursday.
Israeli defence minister Yoav Gallant has held talks over the possibility of expanding Israel’s military offensive – as tanks were pictured on the country’s border with Lebanon.
In a statement on Saturday, Mr Gallant’s office said he was conducting “an operational situation assessment” regarding what it called “the expansion of IDF (Israel Defence Forces) activities in the northern arena”.
Israeli tanks and troops were later pictured near the border, in what Sky News’ security and defence editorDeborah Haynes said is the “clearest sign yet” that Israel’s conflict with Hezbollah is “about to expand even further”.
The military said it was mobilising three more battalions of reserve soldiers to serve across the country. It had already sent two brigades to northern Israel to prepare for a possible ground invasion.
The deployment comes after Hezbollah confirmed that its leader of more than three decades Hassan Nasrallah was killed in an Israeli airstrike in Beirut on Friday.
The militant group – which is aligned with Iran – vowed to continue its fight against Israel even as attacks continued to bombard areas around Lebanon’s capital.
At least six people were killed in the strikes – not including Nasrallah – and 91 were wounded, according to preliminary figures from Lebanon’s health ministry.
The United Nations high commissioner for refugees said that airstrikes led to the displacement of “well over 200,000” people inside Lebanon.
“More than 50,000 Lebanese people, and Syrians living in Lebanon, have crossed the border into Syria,” Filippo Grande wrote on X on Saturday.

‘Israel is on the move’
In his first public remarks since the killing, Israeli Prime Minister Benjamin Netanyahu described Nasrallah as a “terrorist” and said his killing would help bring displaced Israelis back to their homes in the north and would pressure Hamas to free Israeli hostages held in Gaza.

Netanyahu: Nasrallah ‘was the terrorist’
But with the threat of retaliation high, he said the coming days would bring “significant challenges” and warned Iran against trying to strike.
“There is no place in Iran or the Middle East that the long arm of Israel will not reach, and today you already know how true this is,” Mr Netanyahu said.
“We have great achievements, but the work is not yet complete. In the coming days we will face significant challenges, and we will face them together,” he added.
“We are determined to continue to strike at our enemies, return our residents to their homes, and return all our abductees. We do not forget them for a moment.
“Israel is on the move.”
Iranian Supreme Leader Ayatollah Ali Khamenei condemned the killing and announced five days of mourning. He said Lebanon will make Israel “regret their actions” and Nasrallah’s blood “will not go unavenged”.
In a letter to the UN Security Council, Iran’s UN ambassador Amir Saeid Iravani asked for an “emergency meeting” of the 15-member body, calling on it to “compel Israel” to cease all military action in both Gaza and Lebanon and “comply with relevant UNSC resolutions”.
Meanwhile, hundreds of protesters took to the streets of Tehran, waving Hezbollah flags and chanting “death to Israel” and “death to Netanyahu the murderer”.
People also gathered in the Lebanese city of Sidon and in Amman, Jordan, to mourn Nasrallah. The 64-year-old had countless followers across the Arab and Islamic world, but was viewed as an extremist in much of the West.
Most of all, is the Middle East about to erupt into a regional conflict that threatens us all? That’s been the warning for almost a year, so is it about to happen?
Hezbollah is a designated terrorist organisation for the US, UK and other Western nations. It has killed hundreds of their citizens over the years.
There is no doubt President Joe Biden has felt what he called a “measure of justice” that Nasrallah has been killed.

US-led diplomacy to contain the Middle East crisis has failed.

A senior Middle Eastern diplomat told Sky News the assassination is a kick in the teeth for the US president.
“For all the bombs and billions he has given the Israelis,” he said, “the least they could have done for him in the last weeks of his presidency was a ceasefire in the region”.
With diplomacy stalled, what happens next depends on both Iran and Israel.
For its part, Iran may feel it has no alternative but to weigh in. It may fear the massive missile arsenal it supplied is so jeopardised it must intervene and save Hezbollah.
Iranians have long regarded Hezbollah as an insurance policy for the day Israel might attack Iran itself. If it sees its ally close to total collapse, might it then weigh in?
If it does, Israel’s allies led by America might feel compelled to come to its defence. The full scale war feared for almost a year could engulf the region.
But there are good reasons for Iran not to rush to action.
The Middle East seems a dangerous and unpredictable place but certain rules and assumptions apply, even in all its chaos.
For all their fanaticism, the ayatollahs of Tehran are pragmatic and seek the preservation of their grip on power above all. That has been a rule of the Middle Eastern jungle since they seized power 45 years ago.
Is it pragmatic or wise to up the ante and more directly support Hezbollah, when it is at its weakest? The Iranian regime is not that strong either, crippled economically by sanctions and mismanagement, and socially and politically by months of civil unrest, albeit now quashed.

There are limits too to what Iran could achieve with direct military intervention anyway in a war that is 2,000km from its borders. The Iranians may conclude this round in the war against Israel is over. They think in long time spans, after all. Time to regroup and move on to fight another day?
There will no doubt be days more of sound and fury, like we have seldom seen before. The mourning and funerals of Nasrallah and his lieutenants are likely to be the focus of intense anger and will raise tensions. But what happens afterwards?
That also comes down to Israel.
It may now feel it has the wind in its sails and seize the moment to invade Lebanon on the ground to push Hezbollah back from the border. That would be an extremely dangerous moment too, potentially drawing in supportive militia and Iranian forces based in Syria.
The hills of southern Lebanon are a treacherous country for a military like Israel’s that relies on infantry and tanks. They could be drawn into a lengthy and punishing campaign that could then destabilise the region.

Then there is Lebanon itself. An uneasy compromise between the warring factions of its civil war in the 1970s and 80s has held for decades but its always fragile status quo is now threatened. The chessboard of its multi-denominational politics has potentially been upended by the removal of its most powerful player.
If Lebanon descends back into factional fighting, regional stability will be undermined too.
The Middle East is in grave danger of further escalation. Western and regional diplomats are working round the clock to pull it back from the brink but recent efforts have all ended in failure and neither Israel nor Hezbollah seem to be listening.
The Israel Defence Forces (IDF) said it carried out a “precise strike” on Hezbollah’s “central headquarters”, which it claimed was “embedded under residential buildings in the heart of the Dahieh in Beirut”.
The first wave of attacks shook windows across the city and sent thick clouds of smoke billowing into the air.
While Israel stressed it had been a “precise” strike, preliminary figures from Lebanon’s health ministry confirmed at least six other people were killed and 91 were wounded.
Israel said Nasrallah was the intended target and initially there were claims he had survived.
However, after several hours of confusion, his death was confirmed by Israel.

“Hassan Nasrallah will no longer be able to terrorise the world,” the IDF said.
Hours later, a defiant Hezbollah confirmed Nasrallah’s death but vowed their fight with Israel would continue after confirming they had fired upon sites in northern Israel.
“The leadership of Hezbollah pledges to the highest, holiest, and most precious martyr in our path full of sacrifices and martyrs to continue its jihad in confronting the enemy, supporting Gaza and Palestine, and defending Lebanon and its steadfast and honourable people,” they said.
Alongside claiming to have killed Nasrallah, the IDF said it had killed a number of other commanders, including Ali Karaki, the commander of the southern front.
The country’s military said the strike was carried out while Hezbollah leadership met at their underground headquarters in Dahieh.
In the aftermath of the most recent attacks, an Israeli military spokesperson declined to comment on whether US-made Mark 84 heavy bombs were used in the strike against Nasrallah.
“The strike was conducted while Hezbollah’s senior chain of command were operating from the headquarters and advancing terrorist activities against the citizens of the State of Israel,” Lieutenant Colonel Nadav Shoshani said in a media briefing.
He continued: “We hope this will change Hezbollah’s actions.”

Hezbollah leader killed says IDF
He added the number of civilian casualties was unclear but blamed Hezbollah for positioning itself in residential areas.
“We’ve seen Hezbollah carry out attacks against us for a year. It’s safe to assume that they are going to continue carrying out their attacks against us or try to,” he said.
Meanwhile, Iran said it was in constant contact with Hezbollah and other allies to determine its “next step”, but Reuters reported the country’s supreme leader was transferred to a secure location in light of the latest attack.
Speaking after the attack, Ayatollah Ali Khamenei called on Muslims “to stand by the people of Lebanon and the proud Hezbollah” and said: “The fate of this region will be determined by the forces of resistance, with Hezbollah at the forefront,” state media reported.
Nasrallah’s death will be a blow to Hezbollah as it continues to reel from a campaign of escalating Israeli attacks.
Nasrallah is latest Hezbollah leader to fall
While Nasrallah’s death is certainly the most high-profile of recent attacks, it continues a trend of Israel targeting Hezbollah’s leadership structure.
Also on Saturday, in the early hours of the morning, the commander of the group’s missile unit and his deputy were killed in another Israeli attack in southern Lebanon.
