SpaceX But the centerpiece of Polaris Dawn is the planned spacewalk.
Five day mission plan Polaris Program / John Kraus Isaacman also detailed the day-to-day schedule for Polaris Dawn, which will be in space for up to five days.
Day one is all about looking for a time when there’s minimal risk from micrometeorite orbital debris, which will determine exactly when Polaris Dawn will launch.
Day two will focus on some of the science and research that Polaris Dawn plans to accomplish — which will total about 40 experiments.

SpaceX is getting ready to launch its next private mission, which will include the first attempt to send humans into space, by the end of the month.
Launched from Florida in the early hours of August, the Polaris Dawn mission is the first of three flights billionaire and Shift4 founder Jared Isaacman purchased from SpaceX in 2022 for his human spaceflight endeavor known as the Polaris Program. 26.
In an interview with CNBC’s Investing in Space last month, Isaacman stated, “We don’t get the freedom of any time of day to launch but I think it’ll work out to [be] pretty close to dawn, which is very appropriate given the mission.”.
Just as he did in 2021 during the historic Inspiration4 flight, Isaacman will be leading this mission. He is once again in charge of a team of four, consisting of his longtime coworker Scott Poteet, who is flying, and two SpaceX workers, Anna Menon and Sarah Gillis, who are the flight’s medical officer and mission specialist, respectively.
Instead of traveling to a specific location, the crew’s multi-day journey will involve free-flying and tracking orbits that they hope will be far from Earth.
“Humans haven’t traveled to such a high altitude in more than 50 years,” stated Isaacman.

Polaris Dawn’s planned spacewalk, however, is its focal point.
For many years, astronaut missions at NASA have included extravehicular activities, or EVAs, when maintenance outside the International Space Station is required. But an EVA has never been attempted by a private company.
Isaacman acknowledged that he and his crew have been thoroughly trained for the moment when they will be “surrounded by death,” which comes with doing a spacewalk.
The vacuum chamber is the only object that can be compared to it, and there you will experience the closest thing to being in vacuum or space. In addition to the psychological strain of being in such a hostile environment, that undoubtedly gives you the actual feelings of pressure and temperature changes, according to Isaacman.

The Polaris Dawn crew schedule, which will be in space for up to five days, was also described by Isaacman.
The first day’s work is to pinpoint the exact launch time of Polaris Dawn by identifying the lowest risk window for micrometeorite orbital debris. Isaacman stated that the crew will perform comprehensive inspections on SpaceX’s Dragon capsule Resilience once they have reached an orbit spanning 190 kilometers to 1,200 kilometers.
Before traveling up to 1,400 kilometers in altitude, it is crucial to ensure that the vehicle is error-free, according to Isaacman.
Additionally, the spacecraft will make early passes over the South Atlantic Anomaly, a region of high radiation.
Our two or three high-altitude passes through the South Atlantic Anomaly will account for nearly all of the mission’s radiation load and be comparable to three months on the International Space Station. Therefore, you should ideally take that as low as you can because, even at 200 kilometers, the radiation level there is significantly higher, according to Isaacman.
The second day will be devoted to a few of Polaris Dawn’s planned forty-odd experiments in science and research. In addition, the team will test the EVA suits in preparation for the spacewalk.
In order to confirm that dot. When comparing microgravity to what we have tested on Earth, nothing is unexpected, according to Isaacman.
The EVA is the main event on day three.

Watch now.
So who will make the spacewalk on behalf of the crew?
It’s being vented down to vacuum inside the spacecraft, and we’d say all four of us are doing it, according to Isaacman.
Merely providing support, Poteet and Menon remain inside Dragon, while Gillis and Isaacman venture outside.
It is anticipated that the entire EVA will take two hours to complete. It was important for Isaacman to emphasize that the spacewalk “is really a test and development” procedure.
There is a limited amount of oxygen and nitrogen available, so we want to learn as much as we can about the suit and the operation, according to Isaacman.
The mission commander stressed that “a lot of cameras” will be dispersed both inside and outside the capsule as part of Polaris Dawn’s plans to livestream the spacewalk.

SpaceX’s spacesuits are a vital piece of equipment meant to enable the EVA.
Over the last few years, the company has been developing its EVA suit by utilizing its black-and-white, minimalist IVA suit, which is used by astronauts for intravehicular activity in case of emergency. According to Isaacman, the EVA suits are the outcome of years’ worth of testing various materials over hundreds of hours.
Therefore, Isaacman stated, “learning as much as we can about the suit is our primary goal.”.
“Creating the future generation is the focus of everything. The design of these suits is still being refined so that SpaceX will eventually have hundreds or thousands of them for use on the moon, Mars, in [low Earth orbit], and other locations. It’s not an easy task to build a new EVA suit, he continued.

Like his first orbital flight, Isaacman hopes that Polaris Dawn will inspire others while also pushing the envelope of private spaceflight.
“This is the inspirational aspect of it. People get excited about anything that differs from what they’ve seen in the past 20 or 30 years, asking themselves, ‘Well, if this is what I’m seeing today, I wonder what tomorrow’s gonna look like, or a year after that.'”
