Today's 'guest' is HAD's This Month in Astronomical History. I'll be reading more essays from the archives: Emily McMahon's November 2020 essay titled, "Sedna: In the Depths of the Solar System", and Dr. Ken Rumstay's November 2022 essay titled, "Lunokhod 1 - The First Extraterrestrial Rover". Please note that Emily was a high school student when she wrote her essay, so you don't have to be an astronomer or astrophysicist to write for TMIAH.
H'ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society. We're here to share stories from and about the people who study the stars, planets, and the cosmos. We'll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were "in the room" during pivotal events within the last 50 years or so.

Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes outer space and the people who study it. She quite enjoys working as HAD's podcaster, sharing astronomy stories to you.
