Free Fall/Falling Objects Centers Explanation
... The astronauts experience weightlessness not because there is no gravity. Rather, weightlessness occurs because they and their spacecraft are free-falling in gravity. When two objects fall freely, one can float inside the other until they both reach the ground. The astronauts float inside the space ...
