“Here Is the Beautiful Place: Who Could Mistake It? Here Is Odysseus' Hall!”

The airless moons of our solar system are testaments to impacts; their surfaces peppered with craters large and small.

And I do mean large. Saturn’s moon Tethys is an interesting place all on its own — an icy world a thousand kilometers across — but its captivating mien is punctuated by an ungodly vast impact basin named Odysseus.

Did I say “ungodly”? It’s actually quite the opposite, or at least “gods-like”. I explain what I mean in my bi-weekly article for sen.com: “Space Odyssey”.

The article is subscription only, but for five bucks a month you get a lot of really solid content — not just me, but also from folks like Emily Lakdawalla and Lucie Green. I could compare that price to a cup of coffee (and its ephemeral effects), or downloading an app you’ll never use, or getting a forgettable movie off pay-per-view, but you know what things cost versus their impact on you. $5 ain’t much, and it delivers space right to your browser.
