Is There Zero Gravity On The ISS? Here's How It Works
SMRTR summary
The International Space Station experiences microgravity, not true zero gravity, as Earth's gravitational pull remains at 90% of surface strength at the station's 250-mile altitude. Astronauts float because the ISS and everything inside continuously free-fall around Earth at 17,500 mph, creating a weightless environment essential for space research.
