From the LITD Archives: Eclipsing Mimas

Originally published on May 16, 2009. LITD is almost 3 years old! This animation, made from a series of 8 raw images taken by Cassini on May 14, shows Saturn’s moon Mimas being eclipsed by another object…..a neighboring moon, perhaps? It’s not mentioned, but it definitely seems to be something of similar size, and round….

Mimas and the Rings

Mimas hovers in front of Saturn’s rings in a color image composed from raw Cassini data taken on January 31, 2011. I used data taken with Cassini’s green, infrared and ultraviolet spectral filters to compose this colorized version. Known as the “Death Star” moon, 250-mile (400 km) -wide Mimas’ northern hemisphere is dominated by the 80-mile…

Eclipsing Mimas

  This animation, made from a series of 8 raw images taken by Cassini on May 14, shows Saturn’s moon Mimas being eclipsed by another object…..a neighboring moon, perhaps? It’s not mentioned, but it definitely seems to be something of similar size, and round. Mimas is best characterized by its large-scale Herschel crater in its…

Cassini Mission Highlight: Mile-High Spikes Along Saturn’s B Ring

A field of spike-like structures rise up over two miles from the outer edge of Saturn’s B ring in the amazing image above, captured by Cassini during Saturn’s spring equinox in August 2009. These pointy perturbations are caused by the gravitational nudges of tiny (~1/2 mile) embedded moonlets traveling around Saturn within the B ring, causing fine icy…

Yes, Obi-Wan, That’s a Moon

Saturn’s 250-mile-wide icy moon Mimas shines in direct sunlight and reflected light from Saturn in this image, a composite of raw images acquired by NASA’s Cassini spacecraft on Jan. 30, 2017 and received on Earth today, Feb. 1. This is a bit of a “Frankenstein” job I made, assembled from five separate narrow-angle camera images taken in…

That’s No Space Station, It’s a MOON!

First Alderaan, then Prometheus?? Here we go again! Saturn’s moon Mimas looks uncannily like the Death Star, and this animation by Diamond Sky Productions makes the resemblance even more apparent. Now witness the power of this fully-armed battle station! (No shepherd moons were harmed in the making of this video.) Video © Diamond Sky Productions,…

Daphnis Is Back!

It’s been a while since I posted an image of my favorite moon of Saturn, but while looking through some recent raw images returned by the Cassini spacecraft I spotted it: Daphnis, the little sculptor shepherd moon!

A Golden Oldie

Time to go “all way back” to 2006! In this Cassini image beautifully color calibrated by Gordan Ugarkovic we see the moon Mimas tucked into the shadow of Saturn’s rings. Nicknamed the “Death Star” moon, Mimas features a large crater with a sharp central peak, giving it a striking resemblance to the infamous sci-fi space…

Textured Trojan

First of all, get your mind out of the gutter. 😉 21-mile (35 km) -wide Helene is a “Trojan” moon of the much larger Dione, so called because it orbits Saturn within the path of Dione, 60º ahead of it. (Its little sister Trojan, 3-mile-wide Polydeuces, trails Dione at the rear 60º mark.) The Homeric…

Blowing off Steam

Remind me again why I love Cassini? Oh yeah, because of images like this. 🙂

May the 4th be with you…

Happy Star Wars Day! Now there’s a holiday I can really get into. 🙂 To celebrate, I felt that it would be appropriate to post about the most Star-Warsy object in our solar system: Saturn’s moon Mimas! Below is a repost from March 29, Now That’s a Moon! Here we go again… This portrait of…

This Week in Space

The Discovery crew outlines the upcoming STS-131 mission (scheduled to launch at 6:21am EST tomorrow), new ISS team members blast off to work from Kazakhstan, Toyota teams up with NASA to investigate some out-of-this-world causes to their products’ malfunctions, Spirit settles down for a long [Martian] winter’s nap,  Saturn’s moon Mimas shows off its retro…
