Astrophiz 234: Hacking Mars Satellites to Watch a Solar Superstorm with Dr Jacob Parrott

In May 2024, the "Mother’s Day Superstorm" slammed into Mars with a force Earth didn't experience. But how do we see a storm on a planet without a magnetic field? In this episode, we sit down with Dr. Jacob Parrott from the European Space Agency (ESA) to discuss his groundbreaking research recently published in Nature Communications. Jacob explains how he and his team "hacked" veteran satellites—the Mars Express and the ExoMars Trace Gas Orbiter—to perform an unintended dance known as "mutual radio occultation." Discover how redundant hardware from failed landers became a cutting-edge sensor for Martian aeronomy, revealing how solar flares strip the atmosphere from the Red Planet. In this episode: • From biology and media internships to ESA’s grad scheme. • The physics of radio occultation: Using signal "bending" to measure atmospheric density. • Retasking the Melacom and Electra antennas for deep-space science. • Processing the data: From raw waveforms to Python and SPICE simulations.
