With hours to go before the Great American Eclipse, nine outstanding guests joined host Mat Kaplan for Planetary Radio Live in front of 1,100 rowdy eclipse and space science fans. Also at Southern Illinois University Carbondale for the show was the Jenny Johnson Band with its new song, “Solar Eclipse.” Bruce Betts arrives later with a post-eclipse What’s Up report. The guys have found one last rubber asteroid to give away in the space trivia contest.
