The ISS is accelerated, and thus it is a non-inertial frame of reference. As the ISS is accelerated towards the earth, the pseudo force will be act in the direction away from the earth. This pseudo force cancels the gravitational force acting on the objects inside the ISS.

Can space stations have artificial gravity?
Artificial gravity can be created using a centripetal force. A centripetal force directed towards the center of the turn is required for any object to move in a circular path. In the context of a rotating space station it is the normal force provided by the spacecraft's hull that acts as centripetal force.
Is there simulated gravity on the space station?
Short-term space travel doesn't really need artificial gravity. In fact, most of the research done on ISS relies on the lack of gravity. And on a long-term mission, say, to Mars, the last thing NASA wants is an even bigger, fuel-hungrier, more expensive spacecraft.
Is there no gravity on the International Space Station?
Yes, astronauts are in free fall on space stations. There is gravity on space stations, and that's the only force acting on astronauts. Since the only force working on the space station itself is also gravity, both the astronauts and the space station are in free fall together.
How fast would a space station have to spin to simulate gravity?
They envisioned a rotating wheel with a diameter of 76 meters (250 feet). The 3-deck wheel would revolve at 3 RPM to provide artificial one-third gravity. It was envisaged as having a crew of 80.
How do space stations create gravity?
Dave: In space, it is possible to create "artificial gravity" by spinning your spacecraft or space station. When the station spins, centrifugal force acts to pull the inhabitants to the outside.
Would a spinning space station create artificial gravity?
Dave: In space, it is possible to create "artificial gravity" by spinning your spacecraft or space station. When the station spins, centrifugal force acts to pull the inhabitants to the outside. This process could be used to simulate gravity.
Why do the astronauts in the ISS float freely?
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. The mass of the object does not matter.
Is the Von Braun Station real?
According to Timothy Alatorre, the lead architect of this space station, who also works as the treasurer and an executive team member at the Gateway Foundation, the Von Braun station is designed to be the largest human-made structure in space and will house up to 450 people.
How fast does a space station have to spin to generate gravity?
An artificial gravity level of 0.1 g can be achieved by a reasonably low rotation rate (5 rpm) at radius as low as 4 m (see Figure 2-04). Likewise at a radius of 4 m, about 15 rpm would be required to produce Earth gravity at the feet (although gravity would be 50% less at the head), or 21 rpm to produce 2 g.
