Spacewalk Repair
Open to everyone until Wednesday, September 30
To keep it, print it while it is open.
Astronauts sometimes go outside a spacecraft to replace or fix equipment that cannot be handled from inside. Tethers attach them and their tools to the structure so nothing floats away.
In the picture
- Waist tether: a line clipped from the suit’s hip ring to the station rail, keeping the astronaut attached.
- Tool tether: a short cord from the tool to the suit cuff, keeping the tool from drifting away.
- Power tool: a handheld driver that loosens or tightens fasteners on the battery unit.
- Battery unit: a rectangular module on the station truss that can be swapped during a spacewalk.
Examples
- A climber clipped to a safety rope while working on a cliff.
- A phone secured by a wrist strap so it does not fall from a balcony.
Key takeaways
- Tethers keep astronauts and their tools from drifting off into space.
- Tools are designed to be held and secured while wearing thick gloves.
