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.

Today is a good day to reread this @jerusalem.bsky.social piece on Paul Ehrlich, Zero Population Growth, the Green Revolution, ecofascist immigration politics, and NIMBYism.

The People Who Hate People
Of all the objections NIMBYs raise to new housing and infrastructure, perhaps the most risible is that their community is already too crowded.
