Vice President (2023-2024): Br. Guy Consolmagno (Director, Vatican Observatory, Vatican City State)

 

Brief Biography:

My own passion for meteorites was born in my undergraduate studies at MIT. I remember actually leaping out of bed every Tuesday and Thursday with excitement, knowing that I would have a class in meteorites from the charismatic John Lewis.

At my first MetSoc, in 1976 in Bethlehem, Pennsylvania, I presented work on the evolution of basaltic achondrites that was directed by my PhD advisor at the University of Arizona, the late Mike Drake, himself a one-time MetSoc president. After my talk, I was met in the hallway by the very imposing figure of Jerry Wasserburg. “That was a fine talk,” he told me. I preened. Then he continued, “But tell me… do you actually believe it?” It was a great question from a great scientist, and emblematic of what made MetSoc meetings great.

When I switched my interest to planetary magnetism, writing a thesis with Randy Jokipii, I continued to rely on meteoritic data for both the nature of the dust that would interact with the magnetic fields and the possible effects of Al-26 decay in ionizing the surrounding nebula. Analyzing FUN anomaly data as a post-doc let my advisor Al Cameron to theorize a new kind of nucleosynthetic process for Calcium. And when I did theoretical models for icy moon evolution I assumed that the rocky components of those moons would be meteoritical.

In the mid 1980s I took a break from scientific research, first to teach with the US Peace Corps in Kenya and at Lafayette College in Pennsylvania (not far from Bethlehem), then to go through my requisite studies upon entering the Jesuit order. But once I was assigned to the Vatican Observatory in Rome, I was given a most welcome and challenging assignment. My boss, the observatory director George Coyne, looked me in the eye and said: “do good science.” Period. The science in question was up to me.

More moon models? More magnetism? But I discovered that the Vatican Observatory had a collection of over a thousand meteorite samples. I recalled how much I had wished that someone had measured their physical properties for values that I could have used in my models. Mostly, though, I recalled how much I enjoyed going to MetSoc meetings. That’s where I found the friends who would be interested in the stuff I had to present. That’s why I chose to concentrate my research on meteorites.

Since then, my colleagues and I have measured thousands of meteorites around the world for density, porosity, magnetic susceptibility, conductivity, heat capacity, and now even thermal expansion. Much to our delight, the data we’ve provided have helped the field understand the nature of asteroids and how they’ve evolved over time. I took part in ANSMET in 1996, hosted a MetSoc meeting in Rome in 2001, served on the MetSoc council for 2003-2006, and was named a Fellow of the Society in 2008. I was honored to give the Barringer Lecture at the MetSoc meeting in Moscow in 2018.

Meanwhile, for my sins, Pope Francis appointed me director of the Vatican Observatory in 2015; my term will expire in 2025. That has meant cutting back on a lot of my scientific activity, including turning over the curation of the meteorite collection to my colleague and friend Bob Macke. Nonetheless, MetSoc is the one meeting I still do my best to try to attend every year.

To be able to serve the Meteoritical Society, a society that has always been close to my heart, would be a tremendous honor. I thank you for this nomination, and I look forward to being of service to our Society and its members.

Statement of Priorities for the Meteoritical Society:

Three traits of the Meteoritical Society have always struck me. The first is its international nature; the second, its close ties to the amateur and collector community; and the third, its intimate and friendly atmosphere.

One of the strengths of meteoritics as a field has been that it is relatively small and informal. There are not large sums of money involved in what we do, we don’t depend on billion dollar spacecraft missions, and so there is not the same sort of intense competition for resources (or glory) that leads to tensions in other fields.

But we are now entering a time when our science is very much of interest to those who run spacecraft missions — not only sample missions, but landing missions where knowledge of the surface properties is essential to the success of the mission. And looming on the horizon is the commercial exploitation of space material which inevitably will change the way that our field is understood, and funded.

The more immediate concerns for the Society are the nature of future MetSoc meetings in the light of the uncertainties surrounding Covid and whatever future variants may affect our ability to travel and meet face to face. And of course we face the never-ending pressure on the funding for our science, modest as it may be compared to other fields. These are all tied to the looming ecological situation, with effects ranging from new pandemics to political crises that may have a large impact on the kind of science we can do and where we can do it.

The challenge thus for us will be to address these changes, immediate and long term, without losing the intimate and friendly character of our Society and its ability to welcome new contributors, both students and non-professionals, from around the world.

In that regard it is worth remembering our history. The Meteoritical Society was founded during the Great Depression and in its earliest years endured the disruption of a World War. But even in spite of that, we were able to maintain and extend our international nature, more even than our colleagues in the other astronomical sciences. And since then, the very nature of collecting meteoritical samples has kept us aware, and sensitive to, the larger international community and the need for close cooperation with those who find our samples and bring them to our attention.

What remains is to make sure that we never lose the welcoming nature of our gatherings, especially our ability to engage in lively and sometimes spirited arguments on points of science with the courage that comes from knowing that, at the end of the day, we are all kindred spirits, passionate about the same wonderful bits of space that we get to hold in our hands.

 

Secretary 2023: Jutta Zipfel

Jutta Zipfel is curator of the Max-Planck-Institut meteorite collection which is on permanent loan at the Senckenberg Naturmuseum and Forschungsinstitut in Frankfurt, Germany. She also has a teaching assignment for cosmochemistry at the Goethe University in Frankfurt.
