SpaceX has successfully launched the first all-civilian flight into orbit. The mission, known as Inspiration4, lifted off on Wednesday and is expected to orbit around Earth for three days, making it the first space mission without any professional astronauts on board. Leroy Chiao, former NASA astronaut and ISS commander, joined Cheddar to discuss the significance of the mission, the many safety redundancy checks it had to go through, and what it means for the future of space tourism.
