True or myth: no gravity in space?

True or myth: astronauts float because there’s no gravity in space. Myth. About 250 miles up, where the ISS flies, gravity is still about 90% as strong as on the ground. Astronauts float because they’re falling. The station flies sideways at about 17,500 mph, so as it falls toward Earth, the ground curves away beneath it just as fast. That’s an orbit: a fall that never lands. The station, the crew and everything inside fall together, so nothing presses on anything, and they float. Did this one get you?
