The Inspiration 4 crew is slated to launch Wednesday at 8.02 p.m. ET atop SpaceX's Falcon 9 rocket, reports The Verge.
Jared Isaacman, a billionaire entrepreneur and philanthropist, booked the Crew Dragon capsule last year and picked three normal folks to ride with him. The exact price he paid SpaceX hasn't been disclosed, but it runs into the tens of millions of dollars.
The crew includes Hayley Arceneaux, a cancer survivor, and physician assistant; Sian Proctor, a geology professor, and Christopher Sembroski, a data engineer.
Since the Dragon will not visit the International Space Station, unlike previous Crew Dragon missions, its docking port was removed and replaced with a dome window.
The window, inspired by the Cupola on the International Space Station, will provide the crew with incredible views of Earth, according to the Inspiration4 team.
Issacman, Arceneaux, Proctor, and Sembrowski are set to arrive at Kennedy Space Center on September 9, ahead of their planned launch, the report said.
The Inspiration4 mission marks SpaceX's latest private astronaut mission.
The company's Ax-1 mission, also planned for the end of 2021, hosts a crew of four private astronauts paying $55 million each for an eight-day trip to the ISS.
In 2018, Musk also announced Japanese billionaire Yusaku Maezawa will hitch a ride around the moon on SpaceX's new rocket system Starship, which is under development.
