How do they make International space station to orbit the earth beyond earth's gravity acting on it? We all know that ISS is rotating at an altitude of just 350km away.How could ISS escape earth's gravitational pull?
Your question presumes that the ISS is beyond Earth's gravity, that it has escaped earth's gravitational pull. This is not correct. All objects with mass in the universe affect all other things with mass in the universe, the effect just gets weaker with distance. So the ISS is feeling the effect of gravity from Earth significantly more than the moon is.
The reason the ISS doesn't just fall to the earth, either directly or gradually spiralling towards the earth, is that it is travelling fast enough around the earth that it is continually "missing" earth. It is sometimes described as 'falling' constantly around earth.
If I am to be properly correct though, the reality is that ISS is in fact falling towards the earth, getting closer and closer to Earth all the time. It needs occasional boosts to push it further back out in it's orbit.
Just to blow your mind a little bit: The ISS is pulling on the Earth with the same force that the Earth is pulling on ISS.
Centrifugal force is too small to cancel gravity. The ISS, as all the satellites, are actually "always falling", but the horizontal component of their speed will always take them over the horizon line, keeping the distance to Earth constant. You have a very good explanation here
