Congratulations to the hundreds of collaborators at NASA, for the successful landing of the Perseverance rover on Mars. The mission was eight years in the making.
[From CNN online] The path Perseverance will traverse on Mars is about 15 miles long, an ‘epic journey’ that will take years. What scientists could discover about Mars, though, is worth the journey. To accomplish its goals, Perseverance will drive a little less than 0.1 mile per hour, three times faster than previous rovers.
