In general, the kind of year we’ll experience gets its label at the end of the year. 2005 was the year of the never-ending hurricane season. 2017 was the year we experienced an eclipse and lost Cassini. 2020 was the year satellite constellations went from a handful to hundreds of spacecraft. 2022 was the year of Mars exploration with Curiosity, Percy, Ginny, Insight, and Tianwen-1. Each year gets to define itself, and it is up to us to fight or embrace what that year brings us. This year, 2023, is still young, but I’m going to guess that come January 2024, this will be the year of Io. (This episode originally aired on television March 11, 2023)
