The first all-civilian launch from the Space Coast will take place within a five-hour launch window that is set to begin at 8:02 p.m. EDT. Unlike the billionaires before them, these four private citizens will orbit the Earth for three days before splashing down somewhere in the waters off Florida.

Tech billionaire Jared Isaacman is commander of the Inspiration4 mission. Hayley Arceneaux, Inspiration4 astronaut, is a cancer survivor and health care worker. Chris Sembroski, an Inspiration4 astronaut, won his seat via a raffle. Dr. Sian Proctor, Inspiration4 astronaut, is an educator and trained pilot. MORE
