NASA says it's time to "touch the sun." In 2018, the agency will send a spacecraft close to the sun's surface. NASA says the mission could help us understand some of the mysteries involving the star: why its atmosphere is hotter than its surface; what allows it to fling winds out at supersonic speeds; and more. Our guests walk us through the details and explain what they mean for the future of space research and travel.
