Space travel is growing rapidly, and one billionaire businessman has purchased three SpaceX flights in order to push the industry forward. The Polaris Dawn, the first of three flights, will launch later this year, and its crew will conduct the first commercial spacewalk after they've reached the highest orbit in over 50 years. Jared Isaacman, Polaris Program Mission Commander and Founder & CEO of Shift4, joins Closing Bell to discuss the Polaris program's mission, when the first launch will happen and what it will entail, balancing his business with space exploration efforts, charitable efforts with St. Jude Children's Research Hospital, and more.
