AstronautsĀ“ tools are always floating away because of microgravity, so the astronauts have to leave what they are doing and go get their tools. Astronauts also have to use different tools to repair different parts of the interior of the International Space Station, (ISS). The Double Wrench-Driver is a double sided wrench with two different kinds of screwdrivers inside the wrench that can be taken out but still be attached to the wrench. The Double Wrench-Driver will be able to be tethered to the astronauts. The Double Wrench-Driver will be used to fasten and unfasten nuts, bolts, and screws. In order for the astronauts to be able to use the tool they will need to glue the parts of the Double Wrench-Driver together.
