I designed a device that can help you find near by life and or transportation.
you use the three knobs to search the area and can send a blue light for a living thing or red for transportation. It is an evolution of a regular GPS, but i fit it with a satellite and a motion sensor. It is made so the small built-on satellite can retract back into the device so it can be very portable. I think it would help explore space because it would allow people who get lost find a form of life to guide them to safety and give them access to find transportation as well as set coordinates to your original location. It also allows you to input cordinates so you can travel to a specified location.
