Paul Schenk, a scientist who like me is interested in the Galilean moons of Jupiter, works at the Lunar and Planetary Institute and helps put together their Lunar and Planetary Information Bulletin.
When I was there last month he asked if I could contribute an article about Galileo. You can see it in the most recent issue – see:
Lunar and Planetary Information Bulletin
I was thinking of publishing the whole thing here, but you’d probably enjoy reading the other features of this newsletter as well, so go to that site and download it. (It comes as a PDF file. You can also subscribe to it, and have a message appear in your email box every month when a new issue is ready for download.)
