CAPE CANAVERAL, Fla. (AP) — A U.S. billionaire is buying an entire SpaceX flight for himself and three people to circle the globe. The deal announced Monday is the latest for private space travel. Pennsylvania entrepreneur Jared Isaacman aims to use the trip to raise $200 million for St. Jude Children’s Research Hospital. At the same time, he’ll be fulfilling a dream to fly in space. He’s offering the three other seats in the SpaceX capsule to a St. Jude’s health care worker, a donor to St. Jude’s and a customer of his credit card processing business. The orbital mission is planned for October.
