This backpack can create 3D map of its surroundings without GPS

Engineers have now designed a backpack that will generate a real-time 3D map of the terrain aiding moonwalkers in uncharted territory.

The remote sensing mapping system could be a key to survival in the airless wastes of the lunar South Pole. Using the backpack, astronauts will be able to precisely map the topography of the landscape, including deep ravines, mountains, and caves.
