The quality of continuing steadfastly despite difficulties, obstacles, or discouragement.
From Old French perseverance, from Latin perseverantia, from perseverare 'to persist' (per- 'through' + severus 'strict'). The word literally means 'to continue being strict or steadfast throughout.'
NASA's Mars rover 'Perseverance' was perfectly named - it took over a decade of planning and survived the infamous 'seven minutes of terror' during Mars landing. The word itself embodies the human spirit of exploration, as it takes the same quality to send robots to Mars as it does to master a musical instrument or learn a new language!
