Sleeping, Eating and Cleaning in Orbit
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
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.
