Jared Isaacman's big space dream

• The new mission — called Inspiration4 — effectively ushers in a new age of private spaceflight that goes beyond government customers and missions.
• "I'm not nervous at all," Isaacman told me. "I'm immensely confident in SpaceX's technology. I think they're true pioneers, visionaries."

What's happening: Isaacman is giving away one seat on the Crew Dragon to someone who donates to St. Jude Children's Research Hospital and another seat to the winner of a contest for entrepreneurs.

• The fourth seat has been given to a yet-to-be-named St. Jude ambassador who was once treated by the hospital and is now a medical worker.
• So far, the raffle has generated more than $8 million for the hospital, according to the Inspiration4 website.
• The mission also aired an ad during the Super Bowl this weekend.

Behind the scenes: This mission came together in just about two months, Isaacman said, adding that he always knew it wouldn't just be "a couple buddies going up in space together," instead opting for a more impactful message.

• And it's going to be a sprint to launch before the end of the year.

• Once the final crewmates are announced in about 20 days, they will embark on a rigorous training schedule to get everyone up to speed on what it will take to launch to space and return safely home, even as a passenger.
• "I'm certainly not asking people who are fortunate enough to get selected as part of this process to give up their day jobs. But we might be asking for a little bit of flexibility from their employers ... to give us a day here or there, but what we're trying to do is a lot of three- and four-day weekends," Isaacman said of the training.
