This NASA 'lunar  Artemis Astronauts Explore Moon

Backpack' will help

NASA has invented the backpack

which  will use lidar, or light detection and ranging laser light, to generate centimeter-level 3D maps of the moon's surface as Artemis program astronauts do their activities. 

 Lidar will especially be a

  benefit even in low lighting conditions such as what astronauts will encounter near the south pole, their planned landing zone. 

NASA has invented the

  Kinematic Navigation and Cartography Knapsack (KNaCK) .KNAcK's work not only places local features into a larger geologic context, but also will assist with astronaut safety

As future Artemis astronauts 

explore the moon, a new high-tech backpack will assist their mapping as they step into the unknown.

NASA does have high-definition lunar 

maps of the surface to assist in landing activities so ground surveys of the moon will need a helping hand to assist astronauts with selecting rocks for samples

With no GPS within range to map 

features, the backpack will show actual distances to landmarks, which was something that bedeviled astronauts during the Apollo surface missions of the 1960s and 1970s. 

Solar power is better  astronauts on Mars
