Why zero gravity is a myth: The amazing science of ‘floating’ astronauts | NASA’s Michelle Thaller
The lesson explains that astronauts aboard the International Space Station (ISS) appear weightless not because there is no gravity in space, but due to their continuous free fall towards Earth while traveling at high speeds. Despite being 200 miles above the Earth, gravity remains strong, and the sensation of weightlessness arises from the balance between this gravitational pull and their orbital motion. This understanding clarifies the mechanics of orbits and the nature of weightlessness experienced by astronauts and other objects in space.
