Episode 661: Q&A 121: What Stops the Space Station from Re-Entry? And More... Featuring Michael Rodruck
In this week's questions show, I answer questions about how the International Space Station stays above the Earth's atmosphere, does dark matter need a better name? And how do astronomers know they're looking at exoplanets and not sunspots?
