NASA’s Perseverance Rover is the most recent U.S. mission to the Red Planet. I watched the landing Thursday afternoon on NASA’s YouTube channel along with 2.2 million others (note – the broadcast was shared on other channels, so I’m not sure of the total viewership worldwide). The sequencing and animation of final events of the seven-month, 292-million-mile journey was impressive, but the enthusiasm of the Jet Propulsion Laboratory Mission Control team during the final minutes, including the spontaneous celebration after notification of the landing, was inspiring.
