Here’s a Look at Saturn’s Most Tortured Moon
time ^ | Jeffrey Kluger

Posted on 06/15/2015 5:46:56 PM PDT by BenLurkin

Merely one of 62 confirmed or provisional moons orbiting Saturn, Tethys is easily the one with the most compelling life story.

For one thing, it is a good sister to the other moons in the Saturnian brood. At 660 mi. (1,062 km) across, it’s the fifth largest of all of Saturn’s satellites and orbits at an altitude of 182,689 miles (294,009 km). But it does not fly alone. Its tiny siblings Telesto and Calypso—19 mi. and 16 mi. across (31 km and 26 km) respectively—fly with it, with Telesto in front Calypso in the rear, and Tethys herding them along gravitationally like a mama duck

Orbiting lower than Tethys, at 147,572 miles (237,494 km) is the fanciful Enceladus. Squeezed by the gravity of both Saturn below and Tethys and other moons above, Enceladus emits sparkling, ice plume volcanos, which leave bright tendrils behind it and continually fall back down to dust the moon’s face. The result is a world that has been eternally battered by incoming meteorites but never shows the scars, since no sooner does one appear than it is covered up.

Tethys enjoys no such cosmetic advantages. Nearly every one of the uncounted hits it has taken in its 4-plus billion years of life is stamped in its face, giving the rocky, icy world an almost sponge-like appearance. On the moon’s eastern limb is the biggest scar of all, the crater Odysseus, which covers 18% of Tethys’s surface. On the far-larger Earth, that would be the equivalent of a crater the size of Africa.

A crack that runs nearly three-quarters of the way around the moon suggests that it almost didn’t survive the collision. Had the projectile that caused the crater been just a little bigger or moved just a little faster, it would have murdered Tethys outright

You know I considered putting a “purpose prose alert” in the headline. Probably should have.

There’s no telling how many other moons in Saturn’s litter did suffer that fate. It is a matter of cosmic history that Tethys didn’t. And it’s a matter of cosmic fact that we have reason to be grateful.

Curious closing statement. Not only isn't anyone cosmically grateful that Tethys didn't shatter, no one even gives a damn it exists.

It never ceases to amaze me just how many wondrous and awesome (in the original, take-your-breath-away sense of the word) things there are in our little solar system. I admit I’m a little envious of the future generations who will get to see some of those great mysteries unraveled.

Quite shilling for Hillary! *SMIRK*

Reads like a journalism degree trying to wax romantic about science. Ohhh... Time.

Leave it to those ditzy broads at Time.

Planets can be murdered, but not fetuses.

Those coneheads in my father's squadron used bondo to "fix" a crease in the wing of an F8U-2N.

They didn't bother to tell the pilot how they fixed it until after the supersonic test flight...
