Celebrating Yuri's Night 2016 with Astronaut Samantha Cristoforetti

Happy Yuri’s Night! We’re partying under Space Shuttle Endeavour in the first of two shows featuring interviews from the worldwide celebration of space. Star Trek’s Robert Picardo will talk about his new video newsletter, the Planetary Post, and we’ll visit with Samantha Cristoforetti, who returned last June from 200 days aboard the International Space Station. Emily Lakdawalla reports on the spacecraft exploring our solar system this month, while Bruce Betts tells us What’s Up.
