How Do We Do Research in Zero Gravity? We Asked a NASA Expert: Episode 62

How do we do research in zero gravity? Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity.
