When astronauts do a task on the International Space Station, they should have the flashlength. It’s a lamp and the light can transform become a tape measure, that can also clip to an astronaut’s belt or anything else. When one needs to measure length you use the tape measure and use the flashlight to make sure the line is straight. The lamp part comes in handy when an astronaut needs to see something clearly in the dark. They can also use their hands for something else when carrying the flashlength because of the clip. Than after you finish using it, it is small and compact so it won’t take up too much space. This tool is small and portable. It won’t take up much space. The flashlength is a must have for occasions when light is needed, something needs to be measured or both on the ISS.
