J. Marvin Herndon appears to be a crank. Never any coauthors on his papers, other scientists have mantle convection and magnetic field generation completely wrong, there's a nuclear reactor in Earth's core, he named a process he "discovered" after himself, blabbedy blah. http://arxiv.org/find/physics/1/au:+Herndon_J/0/1/0/all/0/1

Really interesting! This got me quickly checking up on what the current state of knowledge is regarding Venus' interior, and we can now say that we understand Mercury's interior better than Venus'. Extrapolating even further, Mercury gives us the only other example we're going to get of a terrestrial planet with a magnetic field that we can explore in situ and this is important for understanding what might allow terrestrial exoplanets to possess a magnetic field, and ultimately, the frequency of earthlike climates around the universe! Kudos to the team for this work.

Take a break from Perseverance's studies related to the early climate of Mars and learn about the early atmosphere of Mercury.
