What are microgravity effects?

Microgravity effects are what happen when things feel almost weightless, like when you're on a really bouncy trampoline.

Imagine you’re floating in a giant pool of air, that's kind of how astronauts feel in space. On Earth, gravity pulls everything down, but in microgravity, that pull is much weaker, so objects and people float around like bubbles in water.

If you’ve ever been in a bouncy castle, you know how it feels to jump and float up, that’s similar to microgravity. In space, astronauts can move easily from one part of the spaceship to another without needing steps or stairs. They just push off walls or objects to float somewhere else.

Your body also changes in microgravity. Without gravity pulling your blood down, it spreads out more, making your face look rounder and your legs feel lighter, like when you take off your shoes and socks at the end of a long day and your feet feel super relaxed.

Microgravity effects are all about how things behave when they’re not pulled strongly by Earth’s gravity, just like floating in a giant bouncy castle!
