If 90 percent of Earth's gravity reaches the space station, then why do astronauts float there? The answer is because they are in free fall. In a vacuum, gravity causes all objects to fall at the same rate. ... Since they are all falling together, the crew and objects appear to float when compared with the spacecraft.

Do you always float in a spaceship?

They are weightless and appear to float because they are in freefall. A spacecraft in Earth orbit is falling towards the Earth (because of gravity) but also moving forward at a speed high enough that the path traveled isn't straight down, but instead a curve that circles the Earth.

Do spaceships have gravity?

Yes, there is a gravitational force acting on everything—but there is also that air drag force that will make the spacecraft slow down as it moves down. If the human is going to stay inside the spacecraft, there must also be an extra force on that human (from the floor).
