Inspiration4 is a planned SpaceX Crew Dragon mission to low Earth orbit operated by SpaceX on behalf of Jared Isaacman. The flight is scheduled to launch on 15 September 2021.[3] With four crew members aboard Crew Dragon Resilience,[4][5] Inspiration4 will be the first crewed space mission to orbit Earth with only private citizens on board,[6][7][8] and the first crewed orbital mission whose primary objective is not to visit a space station since STS-125.


On 1 February 2021, SpaceX announced plans to launch Inspiration4 during the 4th quarter of 2021.[9] It is scheduled for 15 September 2021.[3]


The four crew members have been selected based on four different attributes. As an experienced pilot, including qualification in multiple military jets,[10][11] and as the financial backer for the flight, Jared Isaacman will also be the flight's commander (Leadership). Isaacman purchased two other seats for St. Jude Children's Research Hospital. One seat will be filled by Hayley Arceneaux (Hope), 29 years, a St. Jude employee and former bone cancer patient, now a physician assistant at St. Jude Hospital.[12] The other is Christopher Sembroski (Generosity), who donated and participated in the raffle as part of an attempt to raise US$200 million for the hospital.[13] Sembroski's raffle ticket was not selected[14] but an unnamed friend of his, who was initially selected to fly but declined for personal reasons, gave his seat to Sembroski.[15] The fourth crew member, Sian Proctor (Prosperity), is an entrepreneur who was selected using a format similar to the reality television series Shark Tank.[4] The panel of judges included Marc Benioff, Stephanie Mehta, Mark Rober, and Jon Taffer.[16]

Isaacman and all crew members will undergo commercial astronaut training by SpaceX,[4] including orbital mechanics, operating in microgravity and zero gravity environments, stress testing, emergency preparedness training, mission simulations, and learning about the Falcon 9 launch vehicle and Dragon spacecraft.[17]

The mission will use the Crew Dragon Resilience capsule. This will be the second flight of the spacecraft, which first flew as part of the SpaceX Crew-1 mission and splashed down in the Gulf of Mexico on 2 May 2021.[4][5] The capsule docking adapter, which is normally used to dock with the International Space Station, will be replaced for this mission by an acrylic window, providing views of space and the Earth.[18]


The mission is expected to launch in September 2021 atop a Falcon 9 Block 5 launch vehicle from Kennedy Space Center's Launch Complex 39A (LC-39A). Following three days in orbit, the spacecraft will return to Earth via splashdown in the Atlantic Ocean.[9] The apogee will be 540 km and the inclination will be 51.6°.[3]
