Rachel Maxwell—Io doesn’t have a dynamo, but could Io have remnant crustal magnetism? Maybe! Lava flows on Io may freeze in the magnetic field from Jupiter. A low flying spacecraft with a magnetometer might be able to see this. (Io Workshop 2026)
A photograph of a sketch in my notebook from the Io science workshop, showing a summary of a talk by Rachel Maxwell about how I might freeze in magnetic anomalies from Jupiter’s magnetic field. The sketch shows Jupiter in the background with an enormous magnetic field, shown as green and blue magnetic field lines at emanate from the north and south pole of Jupiter. I was in the foreground and is covered in lava flows. i’ve drawn in hypothetical little magnetic anomalies with their own blue and pink magnetic field lines emanating from the surface of Io, along with a small spacecraft that’s flying low near Io that could measure these magnetic anomalies. There are some text boxes near the sketch that note of variety of things, including that the magnetic field strength at Io from Jupiter is about 1.8 micro-tesla, and that large magnet anomalies greater than 50 km in size could be detectable from a 200 km altitude. Magnetite is likely the carrier of thermal remanence.

Our new survey of parabolas on Venus, and evidence for True Polar Wander at ~1°/Myr is now published! (TLDR @jtuttlekeane.bsky.social was right. nananana BAT region) agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Sketch by JT Keane of a talk at 2025 LPSC (True Polar Wander of Venus as an explanation for misaligned parabolas). Impacts on Venus loft material into the atmosphere. As the material falls back through the atmosphere, winds push it downrange — forming a parabola. This parabola should point west... but old parabolas aren't. Perhaps Venus reoriented! Parabolas are effectively paleo-west indicators. Old, misaligned parabolas might record TRUE POLAR WANDER.

Looking into Wright's publication record, it looks like most of his published research was done with Jonathan Pruitt, a disgraced behavioral ecologist who lost his faculty job at McMaster for manipulating and fabricating data across many papers. I suspect that would be his real problem.
