SpaceX successfully carried out the first commercial spacewalk in human history

On September 12, Musk's SpaceX successfully carried out the "Polaris Dawn" commercial spacewalk mission. Billionaire Jared Isaacman and SpaceX engineer Sarah Gillis each went out of the spacecraft and took a short "walk" in space.

On September 12, Musk's SpaceX successfully launched the "Polaris Dawn" commercial spacewalk mission. Billionaire Jared · Isaacman and SpaceX engineer Sarah · Gillis each went out of the capsule for a short "walk" in space.

This was the first commercial spacewalk in human history, and Isaacman became the first non-professional astronaut to complete a spacewalk, and none of the four people in the space capsule were from a government agency. During this space flight, Isaacman also created an interesting history, becoming the first person to bet on a sports game in space.

It was the first commercial spacewalk ever made, and Isaacman became the first amateur astronaut to complete a spacewalk, and none of the four people in the capsule were from government agencies. In this space flight, Isaacman also made interesting history by becoming the first person to bet on a sports game in space.

In recent years, major companies have entered the space travel market, and SpaceX expects that 3-6 commercial space flights per year will become the norm in the future. Some billionaires are willing to "spend a lot of money" just to experience the short-term weightlessness in space for even a few minutes.

Unlike simply paying for a ticket to enter the capsule, Isaacman is working with SpaceX this time by sharing the R&D costs, with the goal of testing SpaceX's spacesuit in space. Isaacman declined to disclose how much money he has borne, but it is estimated that his share is about $200 million. In addition, another purpose of his trip is to do public welfare publicity for St. Jude Hospital, which focuses on cancer research. His goal is to raise $200 million, half of which he will pay himself.

As early as 2021, Isaacman led the "Inspiration 4" space mission. The four crew members who went into space were all civilians, including bone cancer survivors, veterans, and amateur flying enthusiasts. In order to complete this mission, Isaacman and his friend, former Air Force fighter pilot Scott Poteet, and two SpaceX engineers trained for several months, and the launch was delayed for several weeks due to weather reasons.

At 5:23 a.m. EST on September 10, the Falcon 9 rocket carrying the Dragon spacecraft was launched from the Kennedy Space Center in Florida. On the 11th, the Dragon spacecraft and the Polaris Dawn mission team entered an orbit with a perigee of about 190 kilometers and an apogee of about 1,400 kilometers. After completing six orbits at this altitude, the Dragon spacecraft switched to an orbit with a perigee of about 190 kilometers and an apogee of about 700 kilometers, and planned to conduct the first commercial spacewalk at an altitude of about 700 kilometers from the ground.

The spacewalk officially began at about 6:50 a.m. EST on September 12. Isaacman opened the hatch, climbed up the ladder to look out, and bent his elbows to test the material of his space suit. From the camera on his helmet, it can be seen that the spacecraft is over the South Pacific. Isaacman sighed, "Although there is a lot of work to do after returning home, the earth is really a perfect world at this time."

At about 6:50 a.m. ET on September 12, the spacewalk officially began. Isaacman opened the hatch, climbed the ladder to look out, and performed movements such as bending his elbows to test the spacesuit material. As can be seen from the camera footage on his helmet, the ship is over the South Pacific Ocean at this time. Isaacman lamented, "Even though I have a lot of work to do when I return home, the Earth is a perfect world at this time."

Isaacman returned to the space capsule ten minutes later, and SpaceX engineer Sarah Gillis took over his space suit test, which also took about ten minutes. The hatch of the spacecraft is open for only more than half an hour, while in NASA's space missions, the hatch often needs to be open for more than ten hours, and astronauts will go out of the cabin in pairs, performing tasks in groups of two.

The hatch of the spacecraft is only open for more than half an hour, while in the space missions of the United States Space Agency, the hatch often needs to be open for more than ten hours, and the astronauts will go out of the capsule in pairs to perform the task in pairs.

In addition, during this mission, although most of Isaacman and Gillis' bodies were outside the cabin, their feet were still inside the cabin and their hands were tightly holding the stairs, so they were not "floating in space" in the strict sense. Even so, the danger they faced was still very high, and there were phenomena such as the hatch failing to open automatically and bulging at the seal.

In addition, during this mission, Isaacman and Gillis were not strictly "space floating", although most of their bodies were leaning out of the capsule, their feet were still in the capsule, and their hands were tightly clutched to the stairs. Even so, the danger was high, and there were cases where the hatch could not open automatically and the seals were raised.

Isaacman was born on February 11, 1983 in unx City, New Jersey. He claimed that he was "a bad student since childhood and didn't like being in the classroom." He dropped out of high school at the age of 15, and at the age of 16, he founded the successful payment company Shift4 Payments in the basement of his parents' home. The company is currently responsible for processing payments for one-third of restaurants and hotels in the United States, including well-known brands such as Hilton, Four Seasons, KFC and Arby's, and processes more than $260 billion in transactions each year.

After his success in the payment field, Isaacman also founded Draken International in 2011, which trains Air Force pilots. The company currently owns the world's largest private military aircraft fleet. In 2019, Isaacman sold a majority stake in Draken International to Wall Street's Blackstone Group, making himself a billionaire. Forbes magazine estimates that Isaacman's personal net worth is approximately US$1.9 billion.

Isaacman is a "thrill seeker" in life. His biggest hobby is "flying a MiG fighter at supersonic speed to get rid of the tension and boredom of working more than 80 hours a week." In 2009, he also set the fastest time record for round-the-world flight, which was broken by New Zealander Andrew in 2018.

Isaacman once said: "I do believe that you only get one chance at life. You have an obligation to live it to the fullest, as long as you are able. You never know when it will be your last day."

In 1965, Soviet cosmonaut Alexi Leonov opened the precedent of spacewalking, and a few months later, Ed White of NASA also performed a spacewalk. As of the 12th of this month, a total of 263 people from 12 countries have performed spacewalks. Spacewalks have always been considered very dangerous and were previously performed by professional astronauts.

"A spacewalk is completely different than just riding on a rocket, getting some zero-G time and coming back to Earth," said retired NASA astronaut Chris Cassidy.

Chris ·Cassidy, a retired NASA astronaut from United States, said, "A spacewalk is completely different from just taking a rocket, getting some zero-gravity time and returning to Earth."

Cassidy worried that Isaacman was setting a bad precedent by which wealthy people could "jump the queue" for spacewalks with minimal training.

Cassidy fears that Isaacman has set a bad precedent that a wealthy man might jump into a queue for a spacewalk with little training.

Ilan Kelman, a risk and disaster analyst at University College London, said it was "inevitable" that non-professionals would eventually participate in spacewalks, but he expected that there would be casualties in the process. "There are many things we can and should do to reduce the risk, but we have to be completely honest with anyone involved, especially when a major accident occurs, the chances of being rescued are low."

"There are many things we can and should do to reduce the risk, but we have to be completely honest with any involved, especially when there is a major accident and the likelihood of being rescued is low."

Isaacman himself admitted after returning to the capsule that the mission was very difficult, but he hopes to contribute to the exploration of space. "I was not born when humans walked on the moon. I want my children to be able to jump and walk on the moon and Mars in spacesuits and venture out to explore our solar system."
