Days after four "non-astronauts" made history by launching into space, the SpaceX Inspiration4 crew landed Saturday night. The crew included tech billionaire Jared Isaacman, who served as mission commander; Hayley Arceneaux, a health care worker and cancer survivor; Dr. Sian Proctor, the fourth Black female astronaut; and Chris Sembroski, a data engineer who won his seat on board the SpaceX Crew Dragon capsule atop a Falcon 9 rocket. They launched Wednesday night from Kennedy Space Center. The group's space trip ended with a splashdown at about 7:07 p.m. ET in the Atlantic Ocean off Florida. The crew of Inspiration4, the first private orbital space mission, spent Friday conducting medical research, talking to pediatric cancer patients via Zoom, giving a live video update on YouTube, playing the ukulele and chatting with movie star Tom Cruise. The Inspiration4 mission is being paid for by Isaacman, who's promoting the flight as a massive fundraising effort for St. Jude Children's Research Hospital. 📸: Associated Press
