My tool is used for saving lives. Its an invention that has never existed before. This tool can be very useful in the future, if an astronaut is in danger and needs to be rescued immediately. How it works: When needed, astronauts will type their ID number to so a dispatcher will know their identity. Then they will press the glowing blue button. It will send a very bright light, which will automatically send the signal to the satellite. After that, it will send their location to people on Earth. Then a rescue ship will come and save the day.This tool is very effective in helping save lives, data, and other information. It is charged by solar and electrical components.
