Trading Onions for Oranges on the Space Station

The International Space Station is a large spacecraft and science lab orbiting Earth. The astronauts who live and work there temporarily sometimes miss the foods and other conveniences they enjoyed at home, but there is nowhere to buy them. Instead, they often trade, or barter, with fellow astronauts for the things they want. With astronauts from different countries with various skills and preferences, there are plenty of opportunities to trade. Listen to hear about a lively barter economy in space, and learn what the astronauts all agree should never be traded.
