NASA’s Perseverance Now Autonomously Pinpoints Its Location on Mars

There is no GPS at the Red Planet, but a new technology called Mars Global Localization lets Perseverance determine precisely where it is — without human help.  Imagine you’re all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are.&
