University of Iowa Will Lead NASA Space Mission to Learn the Music of the Spheres

The big news for University of Iowa will be a NASA satellite mission to investigate how solar wind interacts with Earth’s magnetosphere. You can read the whole fascinating story in this issue of Iowa Magazine.

According to the story, “twin spacecraft known as TRACERS—Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites—will begin their journey to study Earth’s mysterious magnetic interactions with the sun. The satellites will be packed with scientific instruments along with two small, but meaningful, tokens.”

The two small tokens happen to be purple guitar picks that belonged to University of Iowa physicist, Craig Kletzing, who died from cancer in 2023. Kletzing and colleagues got a $115 million contract from NASA for TRACERS. It’s the largest research award in University of Iowa history.

Kletzing played guitar in a few bands, and one them was named Bipolar—which is the only connection to psychiatry that I could see. He was dedicated to work in basic science, and he was often heard to ask “How can we make this simpler?” referring to chunking big scientific challenges into manageable goals. He was a rare person in that he was both a brilliant scientist and a great teacher. One example of his work ethic was that he skipped a meeting with NASA’s top brass in order to deliver a morning lecture on introductory physics to 275 students.

The members of the UI TRACERS team call the project “Craig’s mission.” I’m pretty sure he would have called it a team effort “… to help scientists better understand the powerful forces harmonizing throughout the universe—something the ancient Greeks described as the music of the spheres.”

And that’s what the purple guitar picks represent.
