dark side of the earth
Astronauts at the International Space Station can make one request to talk to an earthling of their choice. For some reason, Astronaut Mark Vande Hei chose Radiolab. A couple weeks ago, we were able to video chat with Mark and peer over his shoulder through the Cupola, an observatory room in the ISS. Traveling at 17,000 miles an hour, we zoomed from the Rockies to the East Coast in minutes. And from where Mark sits, the total darkness of space isn’t very far away.
