Episode 22: Journey to the Sun

Locked up on the Greek island of Crete, Icarus and his dad made wings out of beeswax and bird feathers. They soared to freedom — but Icarus got cocky, flew too close to the sun, and fell into the sea. A few thousand years later, NASA is ready to do the job right. The Parker Solar Probe is scheduled to fly in 2018. The spacecraft has a giant heat shield, tested to withstand 2,500-degree temperatures. For something so basic to all of our lives — and fundamental to the science of astronomy — the sun remains surprisingly mysterious. To learn more, Michelle meets up with Nicky Viall, a NASA heliophysicist working on the mission. She describes how direct measurements of the sun’s super-hot plasma, and solar wind, may dramatically enhance our understanding of the star at the center of our lives. Orbital Path is produced by David Schulman and edited by Andrea Mustain. Production oversight by John Barth and Genevieve Sponsler. Hosted by Michelle Thaller. Photo credit: NASA
