Massive ‘lighthouses’ on the moon could light the way for future lunar astronauts

A lighthouse for the moon — what a bright idea. 

In long-form engineering speak it is called Lunar Utility Navigation with Advanced Remote Sensing and Autonomous Beaming for Energy Redistribution, or LUNARSABER. The idea comes from Honeybee Robotics, a concept selected as part of the Defense Advanced Research Projects Agency’s 10-year Lunar Architecture (LunA-10) initiative.
