The Ed Scott Lecture Series is a tribute to Ed Scott who died in 2021. It is comprised of online lectures, each dealing with developments in a particular field of meteorite studies. The lectures will be presented for a general scientific audience so that members of the Meteoritical Society can learn about questions that drive research in areas outside their own. The series is supported by a donation from Ed’s family.

The Ed Scott Lecture Series is organized through the Membership Committee, with Ian Sanders as the current lead for 2023–2024.

2023 – 2024 Ed Scott Lecture Series

Connection information is provided to MetSoc members via email. Lectures will be recorded and posted to this website for public viewing.

Achondrite Meteorites: Messengers of Early Planetary Accretion and Evolution

Recorded Lecture:

Primitive and basaltic achondrite meteorites provide insights into planetesimal formation and differentiation processes. The increasing number and diversity of achondrite meteorites contribute to a better understanding of chemical reservoirs, accretion timescales, and dynamical evolution of planetary bodies throughout the Solar System. This presentation will give an overview of their petrological significance and comparative chronology in addressing several key questions about the formation of the protoplanetary disk and planets.

Lecture by: Audrey Bouvier, University of Bayreuth

Audrey Bouvier is a cosmochemist and professor at the Bavarian Research Institute of Experimental Geochemistry and Geophysics at the University of Bayreuth. In her research, she principally uses petrological and metal isotope studies of meteorites and returned samples to assess the origin, evolution, and impact histories of planetary materials and their parent bodies. She was a member of the JAXA Hayabusa2 initial analysis chemistry team of Ryugu, and is currently an ESA-appointed member of the Mars Sample Return Campaign Science Group and of the Science Strategy Team on Early Solar System Evolution and Sample Analysis Working Team of the Martian Moons eXploration (MMX) JAXA mission. She received the Nier Prize (2013) and is a Fellow (2018) of the Meteoritical Society.

Mars Sample Return: Why Martian Meteorites and Rover Missions Are Not Enough

Recorded Lecture:

Mars Sample Return is among the most challenging (and costly) mission concepts ever attempted. This presentation will consider why the almost 200 martian meteorites now available are not sufficient to address critical questions about Mars geologic (and possibly biologic) history, and what we might learn from returned samples.

Lecture by: Dr. Harry "Hap" Y. McSween, University of Tennessee

Hap McSween is a petrologist/cosmochemist who has been involved in Mars research since he was one of the original proponents of the idea that we have martian meteorites. He has been involved in multiple Mars spacecraft missions, as well as investigations of many other meteorite types.

IIE Iron Meteorites as Ordinary Chondrites: Surprising Insights into the Chemical Evolution of the Solar Nebula

Recorded Lecture:

Even though the IIE meteorites are irons, a few contain chondrule-bearing clasts. These clasts and the metal fraction have chemical and isotopic compositions that show that they constitute the fourth major ordinary-chondrite group. Considered collectively, these four groups provide insights into the nature of the chemical fractionations that occurred in the solar nebula.

Lecture by: Dr. Alan E. Rubin, UCLA

Alan Rubin received a B.S. in Astronomy from the University of Illinois, Urbana in 1974, after which he worked part-time at the Adler Planetarium in Chicago. He obtained an M.S. in Geological Sciences from the University of Illinois, Chicago in 1979, and a Ph.D. in Geology from the University of New Mexico in 1982. Ed Olsen was his M.S. advisor and Klaus Keil his Ph.D. advisor. While at New Mexico, Rubin also worked with Jeff Taylor and Ed Scott. Rubin was a post-doctoral fellow at the Smithsonian from 1982-1983 under the supervision of Roy Clarke. He went on to UCLA where he joined John Wasson’s group. Rubin has published about 220 research papers on all varieties of meteorites, as well as 50 popular-level articles and three non-fiction books. He notes that, as a garnet, his eponymous mineral is semi-precious.
