The St. Louis Science Center is hosting the traveling Mars Rover exhibit, featuring full-scale models of the Perseverance Rover and the Ingenuity Mars Helicopter from now until June 24, 2024. To kick off the exhibit, there was a special panel on Saturday, June 24, 2023, featuring Ray Arvidson, Mars rover expert and MCSS and James S. McDonnell Distinguished University Professor Emeritus; John Christian, who received his PhD from the Department of Earth and Planetary Sciences in May; and Matt Muszynski, a JPL engineer, as panelists in the Planetarium StarBay. Christian is now a PIXL member on Perseverance. Muszynski has worked with Curiosity, Perseverance, and is now involved with the Mars Sample Return lander development. There were about 200 people in attendance. It was a good panel, with each panelist feeding off of the others. Based on the number of people who came up after the panel discussion, there was enormous interest.
