The November JASA Express Letters cover features a depiction of four autonomous stations used for taking acoustical measurements of the SLS Artemis-I mission. The image comes from the article, “Sound power of NASA’s lunar rockets: Space Launch System versus Saturn V,” by Makayle S. Kellison and Kent L. Gee.

This month’s issue also included an Editor’s Pick you don’t want to miss: “Tidal modulation of very-low-frequency and ultra-low-frequency ambient noise levels,” by Anthony I. Eller, Kevin D. Heaney, and David L. Bradley.
