SpaceX’s first civilian crew will be four. This mission was paid for by billionaire entrepreneur Jared Isaacman, who, in fact, became the first member of the crew. These people will spend from one to several days in Earth’s orbit.
In addition to Isaacman, the doctor’s assistant at Saint Jude Hospital, 29-year-old Hayley Ansero, 41-year-old US Air Force veteran Chris Sembroski, and 51-year-old Sian Proctor, an educator and trained pilot, were selected for the flight.
