2025 Graduation Special (part 1)

diploma-and-graduation-hatWith graduation season upon us, today’s edition of How on Earth is Part 1 of our annual “Graduation Special”. Our guests in the studio today are scientists and engineers who have or will soon receive their Masters or Ph.D. from the University of Colorado in a STEM-related field.  They talk about their thesis research, their grad school experiences, and what they have planned next.

The Lucy Mission

Our guest today is Dr. Simone Marchi, Institute Scientist in the Solar System Science & Exploration Division at the Boulder office of Southwest Research Institute. Dr. Marchi is the Deputy Principal Investigator for NASA’s Lucy mission.  Lucy will be the first space mission to explore a population of small bodies known as the Trojan asteroids, which orbit out at the distance of Jupiter. Lucy has two “practice” flybys of main belt asteroids: Dinkinesh in November 2023, and Donaldjohanson coming up in just a few days on April 20, 2025.

April Foolish Science

Today is April Fools’ day, when jokes and pranks are played, sometimes among friends and family, sometimes on a more public scale.  But why is there such a day for culturally-accepted foolishness? To delve into the origins and history of April Fools’ Day, we talk with Dr. Angus Kress Gillespie, folklorist and professor of American studies at Rutgers University.

You might find it shocking that scientists have a sense of humor, so we also talk with, Dr. Mike Lund from the NASA Exoplanet Science Institute at the Infrared Processing & Analysis Center / CalTech about the tradition among Astronomers to write and even review  humorous research papers for April Fools’ day. These papers are often posted on the arXiv preprint server, and Dr. Lund, the author of several such papers, also is the editor of the Acta Prima Aprilia that shares some of those papers.

Europa Clipper

Today’s show features NASA’s Europa Clipper mission, which launched on October 14th, 2024 on a Falcon Heavy rocket, setting the spacecraft on its 10-year journey to explore Jupiter’s moon Europa.  Europa Clipper carries nine instruments to study this ocean world covered by an ice shell to determine if there are places in the watery depths below the surface that could support life.  The mission’s goals are to study ice shell, the sub-surface ocean, and the moon’s composition and geology.  Our guest is Dr. Bonnie Buratti, a Senior Research Scientist at the Jet Propulsion Laboratory, and Deputy Project Scientist for the Europa Clipper mission.

Science from The Moon

When people talk about going to the Moon, it is often in terms of establishing a station there, or finding water, or doing science about the Moon such as studying moon rocks.  But we can do interesting science from the Moon that can’t be done on Earth, which is our topic today with guest Dr. Jack Burns, Professor Emeritus in the University of Colorado Department of Astrophysical and Planetary Sciences and Department of Physics.  We talk about doing radio astronomy with instruments on the Moon such as ROLSES, LuSEE-Night, and FarView.

Fire Resistant Homes

In this fire prone season, we talk with experts about an ancient building technique that might reduce the chance that a building’s going to burn. Unfired, compressed earth blocks are a building material that involves clay, sand and lime.  Our guests are architect-engineer Lisa Morey and one of her clients, Matteo Rabescini, who had such a home built in Superior, Colorado after the 2021 Marshall fire.  You can read more at Colorado Earth/Nova Terra, Heart of A Building, and Lisa Morey’s substack.

Our Moon

In this episode, we talk with journalist and author Rebecca Boyle about her book Our Moon – How Earth’s Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are. We discuss how the Moon impacts all aspects of our lives including the creation of life. It is a key component to philosophy and religion, culture and agriculture, art and science, sense of time, and sense of our place in the universe.
