On Florida On the shore, at Launch Complex 39A at NASA’s Kennedy Space Center, the SpaceX team is preparing a historic Historic Inspiration 4 mission for the liftoff. It will be the first all-private, all-civilian spaceflight in orbit. Four crew members – Jared Isaacman, Sean Proctor, Chris Sembrowski and Haley Arsenox – have undergone intensive training for the day, although none of them are professional astronauts. The SpaceX crew dragon spacecraft previously took NASA astronauts to and from the International Space Station, but everyone aboard the flight is traveling as a guest of billionaire CEO Isaacman of Shift 4 Payments, who paid for all four seats and participated in the selection of others. Passengers through a series of competitions. (You can read more about the selection process and mission here.)

The Inspiration 4 crew has a five-hour launch window that opens east at 8:02 a.m. Wednesday night. If the weather cooperates and all systems are turned on, the team will explode on their Falcon 9 rocket, and after a little over eight minutes, their space capsule will move into orbit. They will be able to fly about six times more than Richard Branson and Jeff Bezos during their edge-space travel earlier this summer and will be in orbit for about three days.

As early as Saturday evening, the Dragon spacecraft will land on Earth and splash on one of the many potential landing sites off the coast of Florida, where the SpaceX team will be waiting for them, ready to take new astronauts to shore.

How to watch

The launch’s SpaceX webcast will go live on Wednesday, September 15, at 4 p.m. Eastern Time, about four hours before the launch window opens. SpaceX’s preview coverage will include crew features and their lead-up activities. You can stream it here on YouTube or the SpaceX website.

The weather condition forecast has recently been 70 percent to 90 percent favorable, so it is likely to launch tonight. But if they want to scrape tonight, they will try again tomorrow. Their backup five-hour launch window begins Thursday, September 16, at 8:05 p.m.
