Was it a left at that last crater or a right? Without GPS, NASA needs to come up with clever ways to navigate. KNaCK is a realtime mapping system worn on the back. Via Gizmodo:
The Kinematic Navigation and Cartography Knapsack (KNaCK) is a collaborative effort between NASA and its private industry partners to help future explorers find their way around the less-explored south polar regions of the Moon. KNaCK allows for an on-demand, real-time navigation system, and it works by using a pulsed laser that measures distances to nearby objects and surface features. On the Moon, the system could provide backpack-wearing astronauts with a 3D, high-resolution map of their surrounding area, according to NASA.
