"We don't get the freedom of any time of day to launch but I think it'll work out to [be] pretty close to dawn, which is very appropriate given the mission," Isaacman told CNBC's Investing in Space during an interview last month.

Isaacman will be commanding the mission, as he did while leading the historic Inspiration4 flight in 2021. He's once again leading a crew of four, with longtime colleague Scott Poteet joining him as the pilot and Anna Menon and Sarah Gillis, a pair of SpaceX employees, serving as the flight's medical officer and mission specialist, respectively.

The multi-day trip isn't headed to a destination, but instead will be a free-flying mission tracing orbits that the crew hopes will go far from Earth.
