Inspiration 4 Mission


Inspiration4 is the world’s first all-civilian mission to space, and the second fully private crewed spaceflight, after Soyuz TM-30 in 2000. The mission will be commanded by Jared Isaacman, the 37-year-old founder and Chief Executive Officer of Shift4 Payments and an accomplished pilot and adventurer.

Inspiration4 will leave Earth from Kennedy Space Center’s historic Launch Complex 39A, the embarkation point for Apollo and Space Shuttle missions, and travel across a low earth orbit on a multi-day journey that will continually eclipse more than 90% of the earth’s population.

Named in recognition of the four-person crew that will raise awareness and funds for St. Jude Children’s Research Hospital, this milestone represents a new era for human spaceflight and exploration, according to the company.

The crew is composed of Jared Isaacman, Hayley Arceneaux, Christopher Sembroski and Sian Proctor.

About the Crew

Billionaire Jared Issacman, founder of Shift4 Payments, purchased the flight as part of an effort to raise millions for St. Jude Children’s Research Hospital. He is joined by Haley Arceneaux, Sian Proctor and Chris Sembroski. 

Arceneaux, a childhood bone cancer survivor and St. Jude physician’s assistant, was chosen to represent the charity, while Proctor and Sembroski were selected as part of a global contest for a trip on the flight.


The group has been busy the last few months training for their flight. On Friday (Sept. 3), those efforts have paid off as teams from both SpaceX and Inspiration4 officially greenlit the flight.

Both the Dragon crew capsule and Falcon 9 rocket have flown before and are cleared to fly after teams thoroughly reviewed each of the crafts’ systems as well as ground support system data from the launch pad. 

The exact liftoff time will be determined just a few days before launch. Three days before liftoff, the team will narrow the 24-hour launch window down to five hours, taking into account the weather conditions at the launch site, the flight trajectory and at potential emergency landing sites off the Florida coast. 

Once in orbit, the crew will circle the Earth for three days before splashing down in the Atlantic ocean. Since the Dragon will stay free-flying in orbit and not visit the International Space Station, as previous Crew Dragon missions have done, 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 Sept. 9, ahead of their planned launch.
