According to Jared Isaacman, the four-person crew who will be on the upcoming all-civilian Polaris Dawn mission will begin training this month for the first commercial spacewalk in history.
The Polaris Dawn trek, led by Inspiration4 billionaire Jared Isaacman, will also reach the highest level of altitude Earth orbit ever encountered, beating the current record of853 miles above Earth to reach a peak altitude of 870 miles.
If everything goes to work, it will be the furthest people to flee from Earth since the last Moon landing in 1972.
Isaacman wrote in his tweet that he was ready to "rejoin the Polaris Programcrew next week for training."
According to SpaceflightNow, Isaacman announced in a recent interview that the Polaris Dawn crew would complete training after SpaceX completed its busy period of astronaut missions last month, including the return of Crew-3, the launch of the private Ax-1 mission, and the launch of Crew-4.
The Polaris Program team will send the first crew to space on Starship.
Isaacman will conduct a series of launches in the Polaris Program, all of which will be overseen by him.Isaacman has announced that he has an agreement with SpaceX to launch the third Polaris program to become the first human spaceflight aboard its fully recycled launch vehicle Starship.
Before that happens, SpaceX must wait for the Federal Aviation Authority (FAA) to submit its environmental review, giving Starship the lead for the launch of its orbital maiden flight. President Gwynne Shotwell has announced that the launch may take place as early as June or July.
In the meantime, the Polaris Dawn mission will begin early than November, allowing Isaacman and the rest of the crew to have a decent time to prepare for the historic first commercial spacewalk, though Isaacman said he will have a "jammed" training schedule before the liftoff.
Both Isaacman and Sarah Gillis will wear a new extravehicular suit for the spacewalk. All of the crew will have to wear the same suit as the entire Crew Dragon capsule, which will be depressurized for the spacewalk. Both astronauts remaining in the capsule will be exposed to the harsh conditions of space.
