SpaceX: Billionaire CEO Jared Isakman is on the right track to go into space more than any human in 50 years

The first flight in the series of missions, dubbed “Polaris” after North Star, is scheduled to begin later this year and will last up to five days and include a crew of Isaacman and three other people. It is expected to travel to the Van Allen radiation belt, which has an inner range extending from about 400 to 6000 miles above Earth, in part to help the crew research how radiation in space affects the human body. Radiation remains a major concern for spaceflights to the Moon and Mars, SpaceX says, because it requires prolonged exposure to radiation, which could lead to an “increased risk of cancer and degenerative diseases” and other long-term effects, according to NASA.

During this mission, the crew will conduct a space walk, a first for anyone traveling aboard a SpaceX Dragon capsule. Isaacman announced on NBC’s Today Show Monday morning and in an interview with Washington Post.

“We’re going to go further into space than humans have gone since we last walked on the moon,” he said on the Today programme.

It’s not clear if all of this will go according to plan, nor has SpaceX said if it will need to complete additional testing before Isaacman can make his journey into deep space. SpaceX also didn’t address whether there were any updates the Crew Dragon would need to safely complete the mission. So far, the spacecraft has only carried astronauts on flights to low Earth orbit, or the area of ​​space immediately surrounding Earth. Mission Inspiration 4 marks the Crew Dragon’s tallest flight to date, at nearly 360 miles, and Monday’s announcement indicated that Polaris’ first mission will fly at least twice as far.

“We know the space is expensive,” Isakman said when asked about the costs of the Polaris program during a media call, adding that it was already “fully funded.”

“Costs will come down just as with any other groundbreaking technology,” he said. “This is a contribution from myself and SpaceX towards the important goals we want to achieve with the Polaris program.”

Described as a fundraising drive from St. Jude’s Children’s Hospital, Mission Inspiration 4 has generated a total of $243 million for the organization. Isaacman donated about $100 million, Musk gave another $50 million and the rest was raised through public donations. Polaris missions are also expected to support the same cause.

On Polaris’ first mission, Isaacman will be joined by veteran Air Force fighter pilot Scott Poteet and two SpaceX operations engineers – Sarah Gillies and Anna Menon, who will serve as the onboard medical officer. Isaacman will be the only crew member with previous spaceflight experience.

Poteet is a former Vice President of Shift 4 who spent 20 years in the Air Force. Petit has also served as flight director on the ground in support of Ilham 4. He and Isaacmann are also frequent aviation partners.

Gillis and Menon may be the first SpaceX employees to travel to space.

Details about the spacewalk the Polaris crew plans to perform on the first flight are light, but a press release states that they will use a “SpaceX-designed Extravehicular Spacesuit (EVA), which has been upgraded from the current in-vehicle (IVA) suit.” The IVA suit refers to the black and white compressed spacesuits worn by NASA astronauts and the Inspiration 4 crew aboard the Dragon during launch and return.

According to its website, the space march will take place when the Crew Dragon flies 300 miles above Earth, or roughly the same height as the International Space Station.

Many technical details are still unknown. The Crew Dragon, for example, does not have an airlock lock, which would allow one person to exit the spacecraft in the EVA while the remaining crew members remain safely locked inside their airtight, pressurized cabin. Without the airlock locked, the entire cabin would become hypo-pressurized – as happened during spacewalks conducted by NASA astronauts during the Gemini missions.

“For this mission, the suit that we will design will be one suit that we will launch [in] Then use similarly with EVA,” Gillis said.

“We will certainly do it safely,” Menon added.

Also on Polaris’ first mission, the crew will test the use of Starlink – SpaceX’s satellite internet business – for communications in space. So far, Starlink has only been used to send internet connectivity to customers on the ground, but Polaris’ press release notes that the system could be used to support communications during orbital flights.

Starship

The flight schedule of the Isaacman spacecraft is not entirely clear. During a presentation about the Starship in Texas last week, Musk said that while he hopes the vehicle — which has so far conducted short, sub-orbital “jump tests” — will conduct its first orbital flight test this year, without a crew. However, that may depend on whether federal regulators give SpaceX approval to launch the Starship from southern Texas, where the company has already built an orbital launch pad and the vast majority of the Starship’s resources are located.

It could mean that Isaacman jumps to the first billionaire who bought the Starship mission – Japanese fashion mogul Yusaku Maezawa. Maezawa has paid SpaceX an undisclosed amount of money to secure a seat for himself and a group of artists on the spacecraft’s flight around the moon, hoping to take off as soon as 2023. Maezawa is still in the process of deciding who to take with him.

Musk also said during the presentation that he hoped the Starship would cost less than $10 million per flight within a few years, which, if possible, would be much cheaper than any other rocket on the market.

The spacecraft is expected to be far more powerful than any rocket ever built by mankind. Musk said he would boast about the poor thrust of the Saturn V rockets that drove moon landings in the past century.
