Correcting a misconception:
Your friend Alex tells you that there is no gravity aboard the International Space Station (ISS) and that’s why the astronauts float. You, having paid attention in science class, know that this can’t be true because there’s gravity everywhere in the Universe, and the ISS isn’t that far from Earth. The Moon, in fact, experiences Earth’s gravitational pull, and it’s a lot further away. Also, you read the other day that gravity on the ISS is 90% of what you experience on Earth, which is plenty to keep you grounded. Using the website below if needed, explain why people float while on the ISS.
