Houston, We Have Short Wave On The Line - a podcast by NPR

Speaking to Short Wave from about 250 miles above the Earth, Josh Cassada outlined his typical day at work: "Today, I actually started out by taking my own blood," he said. The astronauts aboard the International Space Station are themselves research subjects, as well as conductors of all sorts of science experiments: Gardening in microgravity, trapping frigid atoms, examining neutron stars. Then, there's the joy of walks into the yawning void of space. Speaking from orbit, Cassada told fellow physicist and Short Wave Scientist in Residence Regina G. Barber about research aboard the station, what it takes to keep the ISS going and which countries' astronauts make the best food.
