Alert – Billionaire steps outside his SpaceX capsule in ‘dangerous’ first ever private spacewalk… as his historic first words are revealed

Although the spacewalk mission was carried out successfully, it has now been revealed there was one minor glitch along the way.

When Jared Isaacman was exiting the capsule, the automatic door mechanism did not work properly and the crew had to open it manually.

This could have been ‘really dangerous’ and could have ‘changed the whole course of the mission’, according to Sky News’s Thomas Moore.

Images shown on the SpaceX live feed show members of the crew safely back inside the Dragon capsule and sitting behind their screens.

Everyone back at the company’s HQ will no doubt be breathing a sigh of relief.

The spacewalks – which saw mission commander Jared Isaacman and mission specialist Sarah Gillis exit the aircraft and complete a series of mobility tests – have now ended.

The mission sees them become the first two people to carry out a privately-funded spacewalk.

Everyone is back inside and the hatch has been closed, once again separating the Polaris Dawn crew from space.

The crew is now waiting patiently while the atmosphere inside the craft depressurises.

It is expected that this process could take up to 50 minutes.

According to SpaceX, the mission is going smoothly.

The first words of billionaire Jared Isaacman as he stepped out of the spacecraft have been revealed.

‘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.

Isaacman, 41, exited first about 6:52 a.m. ET (1052 GMT) as the craft was flying over Antarctica and .

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.

Sarah Gillis was told she had to reutrn to the capsule as she only had what sounded like 5.9 minutes of oxygen supply remaining.

She replied ‘Copy’ and the crew remained calm.

However, this was certainly a reminder of one of the perils of the mission.

Sarah Gillis has left the capsule and is carrying out mobility tests.

She has around one minute left of her spacewalk before returning.

It is now Sarah Gillis’s turn to exit the capsule and carry out mobility tests.

We are now seeing the first views of the first ever commercial space walk.

Mr Isaacman has emerged from the capsule and is now in space as the space craft flies over and Antarctica.

Jared Isaacman has opened the hatch allowing the crew to exit the capsule.

He started turned the leaver, while his fellow crew member Sarah Gillis pushed the button to release the hatch.

Cheers of celebration could be heard on the broadcast from the control room.

The pre-breathing process has now finished and the crew has started venting the cabin.

Spacce X has said the pressure inside the cabin has started to go down.

Astronauts must complete the pre-breathe phase before they are able to exit the capsule.

The process takes around 19 minutes and involves astronauts breathing in oxygen to purge the body of nitrogen.

Divers use a similar procedure.

The astronauts are still in the ‘pre-breathe’ phase and are waiting to be given the clear to open the hatch.

The pressurisation of the space suits has started – a process which is due to take around three and a half minutes.

This means the spacewalk has officially begun!

The astronauts have been given the go ahead to complete the mission.

The audio from Space X’s live broadcast indicated that the initial safety checks on the spacesuits have been carried out.

The final checks on the safety equipment are currently underway.

The faces of Jared Isaacman and Scott Poteet have been seen for the first time today inside the capsule.

The final checks are now being carried out and the mission is due to begin within minutes.

The first live footage has also been shown from inside the Dragon capsule on the SpaceX broadcast.

The astronauts have already put on their space suits and have started ‘pre-breathing’ .

A host on the SpaceX live broadcast said: ‘They’ve been undergoing a process called pre-breathing, where the atmosphere pressure inside Dragon is slowly decreased and oxygen is increased, to prepare their bodies for the [spacewalk] suit environment.’

He added that they began putting on their space suits ‘some time ago’.

Spaceflight safety experts have warned the crew faces potentially deadly risks of radiation exposure and rapid changes in pressure that can cause life-threatening sickness.

The billionaire Jared Isaacman, 41, is most well known as the founder and CEO of the American payment processing company Shift4.

Isaacman founded the company in 1999 out of his parent’s basement when he was just 16 years old.

After dropping out of high school to work as a cybersecurity consultant, Isaacman used a $10,000 loan from his grandad to convince a bank to certify him to sell credit card terminals.

That business ballooned and now handles transactions for a third of America’s restaurants and hotels – processing more than $200 billion in payments every year.

Previously only state-backed space agencies have sent astronauts on spacewalks due to the extremely high risks involved.

Floating beyond the protective walls of a spacecraft is considered to be one of the most dangerous tasks an astronaut can undertake.

In this case, that risk will only be heightened by the fact that none of the crew except for Isaacman have ever been in space before.

Additionally, since the Dragon spacecraft does not have an airlock, the entire craft will need to be depressurized at once.

That will expose all four crew members to the harsh conditions of low orbit and will break the current record for most people simultaneously in the vacuum of space.

The Polaris Dawn mission launched from the Kennedy Space Centre in Florida on September 10 at 5:23 am ET after days of delay due to weather and a helium leak.

Yesterday, the SpaceX Dragon Crew spacecraft carried its crew to an altitude of 870 miles (1,400 km) above Earth – the highest any human has been since NASA’s Apollo missions.

The crew have already made a pass through Earth’s Van Allen Belt – a region of extremely high radiation.

However, the mission’s most dangerous moment will come today as the crew embark on the first private spacewalk.

10.58am UK time: The mission begins

11.28am: Hatch will be unlocked and opened

11.31am: Mission commander Jared Isaacman will exit and begin suit tests

11.44am: Isaacman goes back to his seat

11.49am: Mission specialist Sarah Gillis exits

11.57am: Gillis returns to her seat

11.58am: Hatch is shut and repressurisation begins

12.48pm: Repressurisation finishes

Onboard are the billionaire Jared Isaacman, former airforce commander Scott ‘Kidd’ Poteet, and SpaceX employees Sarah Gillis and Anna Menon.

Apart from Isaacman, none of the all-civilian crew attempting this dangerous mission have any experience in space.

The first ever privately funded spacewalk is due to start just before 11am (5.58 E.T.) UK time.

It had been due to start at 7am but this was pushed back without any reason given for the delay.
