H'ad Astra Historia - Ep 304: More 'This Month in Astronomical History' Sedna & Lunokhod

from The 365 Days of Astronomy

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.     Podcast theme music: "Frost Waltz" Kevin MacLeod (incompetech.com), licensed under creative commons: by attribution 4.0 license (http://creativecommons.org/licenses/by/4.0/)    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.   This Month in Astronomical History:   https://had.aas.org/resources/astro-history   Dr. Mugdha Polimera:   https://www.mugdhapolimera.com/   Sedna: In the Depths of the Solar System   TMIAH  Nov 2020  "Sedna: In the Depths of the Solar System":   https://aas.org/posts/news/2020/11/month-astronomical-history-november-2020   Emily McMahon:   https://www.linkedin.com/in/emilykmcmahon/  https://aas242-aas.ipostersessions.com/Default.aspx?s=88-6D-5F-F3-FF-2E-D2-CD-AA-94-0C-FA-DE-FF-11-5E   Sedna (2003 VB12):   https://en.wikipedia.org/wiki/Sedna_(dwarf_planet) Sedna (Inuit legend):   https://en.wikipedia.org/wiki/Sedna_(mythology)   Kuiper Belt:   https://science.nasa.gov/solar-system/kuiper-belt/   Oort Cloud:   https://science.nasa.gov/solar-system/oort-cloud/   Palomar Observatory:   https://sites.astro.caltech.edu/palomar/homepage.html https://sites.astro.caltech.edu/palomar/about/chronology.html   Mike Brown (CalTech):   https://mikebrown.caltech.edu/   Chad Trujillo (NAU, Gemini):   https://directory.nau.edu/person/cat382 https://www.sciencefriday.com/person/chad-trujillo/   David Rabinowitz (Yale):   https://en.wikipedia.org/wiki/David_L._Rabinowitz https://physics.yale.edu/people/david-rabinowitz   Samuel Oschin 48" Schmidt Telescope:  https://sites.astro.caltech.edu/palomar/about/telescopes/oschin.html   Quasar Equatorial Survey Team (QUEST) Camera:   https://www.astro.yale.edu/mschwamb/Quest_La_Silla_KBO_Survey/Telescope_and_Camera.html   SkyMorph program:   https://ui.adsabs.harvard.edu/abs/1998BAAS...30.1036L/abstract   Palomar Sky Survey:   https://voyages.sdss.org/expeditions/expedition-to-galaxies/sky-surveys/the-palomar-sky-survey/   Gemini Telescope:   https://www.gemini.edu/   Keck Observatory:   https://keckobservatory.org/   Hubble Space Telescope:   https://science.nasa.gov/mission/hubble/ NASAs's Dwarf Planets (including Pluto, Eris):   https://science.nasa.gov/dwarf-planets/   Mike Brown's paper describing Sedna's discovery:   https://web.gps.caltech.edu/~mbrown/sedna/#planets   Sedna webpage (by Mike Brown):   https://web.gps.caltech.edu/~mbrown/sedna/#planets   animation of Sedna's orbit by Robert Hurt (Spitzer Sci Ctr):   https://www.spitzer.caltech.edu/video/ssc2004-05v1-orbit-of-sedna   2012 VP113 'Biden':   https://en.wikipedia.org/wiki/2012_VP113   2015 TG387 'The Goblin':   https://en.wikipedia.org/wiki/541132_Lele%C4%81k%C5%ABhonua https://www.npr.org/2018/10/02/653453443/a-small-planet-with-big-implications   Lunokhod 1 – The First Extraterrestrial Rover TMIAH  Nov 2022  "Lunokhod 1 – The First Extraterrestrial Rover":   https://aas.org/posts/news/2022/11/month-astronomical-history-november-2022   Prof Kenneth Rumstay:   https://www.valdosta.edu/about/news/releases/2017/09/dr.-kenneth-rumstay-honored-with-presidential-excellence-award-for-teaching.php https://meritpages.com/KennethRumstay   HAD News:   https://had.aas.org/news/had_news   Mars Curiosity rover:   https://science.nasa.gov/mission/msl-curiosity/   Soviet Union:   https://en.wikipedia.org/wiki/Soviet_Union   Soviet N1 rocket:   https://en.wikipedia.org/wiki/N1_(rocket)   NASA's Apollo program:   https://www.nasa.gov/the-apollo-program/   Lunokhod ('moonwalker') 1:   https://en.wikipedia.org/wiki/Lunokhod_1   Baikonur Cosmodrome:   https://en.wikipedia.org/wiki/Baikonur_Cosmodrome   Lunar Reconnaissance Orbiter:   https://science.nasa.gov/mission/lro/      Sky and Telescope magazine:   https://skyandtelescope.org   NPR article on Lunokhod 2 rover (discusses Garriott's purchase):   https://www.npr.org/2010/03/20/124956591/lunar-rover-is-spotted-for-first-time-in-37-years   China's Yutu rovers:   https://en.wikipedia.org/wiki/Yutu_(rover) https://www.planetary.org/space-missions/change-4   Sputnik I:   https://en.wikipedia.org/wiki/Sputnik_1   Artemis Program:   https://www.nasa.gov/humans-in-space/artemis/   A Little Bit of Trivia – NASA mission patches Artemis Program:   https://www.nasa.gov/humans-in-space/artemis/   Artemis I:   https://www.nasa.gov/mission/artemis-i/   Marvel's Agents of S.H.I.E.L.D., season 3:   https://en.wikipedia.org/wiki/Agents_of_S.H.I.E.L.D._season_3   Mission patch:   https://en.wikipedia.org/wiki/Mission_patch https://www.nasa.gov/gallery/human-spaceflight-mission-patches/   Loretta Cannon's LinkedIn page (for transcripts' pdf files):   https://www.linkedin.com/in/lorettajcannon-neptuneedit/   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
