Neil deGrasse Tyson Explains Space

What is space? In this explainer, Neil deGrasse Tyson and Chuck Nice explore the boundaries of space...the definition that is. We talk about space a lot, but what is it? You’ll learn about different levels of orbit, where we draw the line of where earth ends and space begins, and how far the International Space Station is from the surface of the earth. Is the ISS always in space? Should our definition of space be based on our planet’s atmosphere? Should we change our definition? How many astronauts have actually been to space? All that and more on another StarTalk explainer! About the prints that flank Neil in this video: "Black Swan” & "White Swan" limited edition serigraph prints by Coast Salish artist Jane Kwatleematt Marston.
