Perseverance. Noun. Meaning: steady persistence in a course of action, a purpose, a state, etc., especially in spite of difficulties, obstacles, or discouragement. As I write this, images have begun to be sent back to earth from the Mars Rover “Perseverance” that touched down on the surface of Mars in February. It took only 215 days to travel from Cape Canaveral in Florida to Mars, however it took decades of planning and learning from previous missions. It will be fascinating to follow the Perseverance’s journey over the next couple of years and see more of the images and data that it sends back.
