Sleeping, Eating and Cleaning in Orbit
Age 11 · Daily Life
In orbit, astronauts float because they are falling around Earth. They attach their sleeping bags, food trays and washing cloths so nothing drifts away.

In the picture
- A sleeping bag fixed to the cabin wall: it keeps a floating sleeper from drifting.
- A meal tray strapped to a table: it holds food packets in place while hands are free.
- A drink pouch with a straw: it lets an astronaut sip without spilling liquid.
- A sealed wet-wipe packet tethered to a rail: it gives a cloth for wiping skin without running water.
Examples
- A water bottle with a straw in a backpack stays closed so it does not leak.
- Velcro straps hold a phone on a bike handlebar.
Key takeaways
- In weightlessness, objects float unless they are attached.
- Astronauts use straps, tethers and sealed containers for everyday tasks.
