00:00Why doesn't the International Space Station crash into Earth if it's constantly falling?
00:04Here's the mind-blowing answer.
00:06The ISS orbits Earth at 250 miles high and speeds through space at 7.6 kilometers per second.
00:14Yes, it's falling, but it's falling sideways so fast that it keeps missing the planet.
00:19A viral simulation by Zack D Films explains this with stunning visuals.
00:23As the ISS falls, Earth curves away beneath it.
00:27This creates a never-ending loop around the planet.
00:30But it's not totally free from danger.
00:32The ISS still skims through the outer atmosphere.
00:35And that thin air causes drag.
00:38It slows the station down.
00:40Which pulls it a little closer to Earth every day.
00:42Without help, it would eventually fall and burn up like a meteor.
00:46So how do we save it?
00:47Every few weeks, small rocket boosts push it higher.
00:50These little nudges keep it in perfect orbit.
00:53It's a dance between speed, gravity, and altitude.
00:57A concept that dates back to Newton himself.
00:59Space is wild, and this simulation makes it clear.
01:03Even something as massive as the ISS is held up by the perfect balance of physics.
01:08the ship is face fromstellar and time is mostly on the planet.
01:11Remember he could've turned up to Earth.
01:13There is no difference.
01:14The ship can befriend with fish.
01:15It's much moreplexed.
01:16The ship can be seen from the Pacific Ocean.
01:17Over the ship.
01:18Then there is a引 bawl and the ship can be added.
01:19There is no difference in doute.
01:20The ship can be added to Earth.
