Jared Issacman (billionaire founder of Shift4 Payments), purchased the plane as part of an effort raise millions for St. Jude Children's Research Hospital. Haley Arceneaux and Sian Proctor are also present.

Arceneaux was a child bone cancer survivor who is now a St. Jude physician's assistant. Proctor and Sembroski were chosen as part of a global competition for a flight on the flight.

The Dragon crew capsule and Falcon 9 rocket were both previously flown and have been cleared for flight after the launch pad teams reviewed all systems and ground support data.

Space.com received a statement from Inspiration4 officials stating that liftoff is scheduled for Sept. 15 with an alternate launch date of Sept. 16.

Only a few days prior to launch, the exact liftoff time will have been determined. The team will reduce the 24-hour launch window to just five hours three days before liftoff by taking into consideration weather conditions at launch site, flight trajectory, and potential landing sites off Florida's coast.

The crew will orbit the Earth for three more days, before splashing down into the Atlantic ocean. The docking port of the Dragon was removed to make sure that it does not touch the International Space Station as the previous Crew Dragon missions did. Instead, the dome window was installed.

According to the Inspiration4 team, the window was inspired by the Cupola at the International Space Station and will offer crew incredible views of Earth.

Kennedy Space Center will receive Issacman and Proctor on Sept. 9, just ahead of their scheduled launch.
