Isaacman also revealed some details about his Inspiration4 mission, as the four gathered Tuesday at NASA’s Kennedy Space Center. Their SpaceX Dragon capsule — currently parked at the International Space Station for NASA — will launch no earlier than mid-September, aiming for an altitude of 335 miles (540 kilometers). That’s 75 miles (120 kilometers) higher than the International Space Station and on a level with the Hubble Space Telescope. AdThe capsule will be outfitted with a domed window in place of the usual space station docking mechanism for their trip.

When she was 10, she had surgery at St. Jude to replace her knee and get a titanium rod in her left thigh bone. Isaacman announced his space mission Feb. 1, pledging to raise $200 million for St. Jude, half of that his own contribution. As the flight’s self-appointed commander, he offered one of the four SpaceX Dragon capsule seats to St. Jude. One will be a sweepstakes winner; anyone donating to St. Jude this month is eligible.

(St. Jude Childrens Research Hospital via AP)NEW YORK – SpaceX’s first all-civilian space flight set for late this year will provide an out-of-this-world fundraising opportunity for St. Jude Children’s Research Hospital, which says it expects to generate $200 million for cancer research and other causes. St. Jude, which specializes in researching and treating pediatric diseases, also stands to increase awareness of its mission. The fourth seat will go to a frontline healthcare worker at St. Jude’s hospital to inspire hope about its mission. Inspiration4 should live up to its name for children at St. Jude’s hospital, Shadyac said.

A female health care worker for St. Jude already has been selected for the mission. Anyone donating to St. Jude in February will be entered into a random drawing for seat No. SpaceX founder and chief executive Elon Musk expects the flight to last two to four days. Isaacman’s $100 million commitment to St. Jude in Memphis, Tennessee, is the largest ever by a single individual and one of the largest overall. While Isaacman and wife, Monica, managed to keep his space trip hush-hush over the months, their daughters couldn’t.
