LPSC 2011: Day 4: Ted Stryk on icy moons and The Moon
Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.
Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing
Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.
Goodies from the January 11 Rhea flyby
Cassini got some incredibly tricky shots during its January 11 Rhea flyby!
Door 1 in the Planetary Society Blog 2010 advent calendar
December really has arrived, and that means that the year is racing to a close. Continuing last year's tradition, I'm counting the days to the New Year with an advent calendar, where each
Pretty picture: Three moons of Saturn
The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.
An update to the Cassini Tour Page
Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.
Cassini catches four little moons in motion
I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.
Goodies from the latest Cassini data release
I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.
Watching the birth and death of moonlets in Saturn's F ring
The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.
Cassini eyes Janus
Four times a year, the Cassini mission releases three months' worth of data gathered from Saturn and its moons to NASA's Planetary Data System.
Sharpest-ever images of Daphnis
As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.
Two moons making waves in the rings
Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.
Dione and Telesto, close on camera but far apart in fact
This image, released today by Cassini's imaging team, is pretty cool; it shows one of Saturn's larger moons together with one of its smaller ones. I probably noticed the nice photo of Dione when it appeared on the Cassini raw images page two months ago, but I know I didn't notice the little speck below and to the left of the bigger moon. That speck is a small moon, Telesto.
A feast of pretty pictures from Cassini
Cassini has it almost too easy. Point at anything in the Saturn system and you're guaranteed of a shot that looks, at least, pretty.
A busy day for Cassini: Dione plus bonus Enceladus and Janus
The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.
Pretty picture: Rhea, rings, and two little moons
Here's a lovely picture whose components came down from Cassini a few days ago.
Helene has two faces
Yes, it's yet another post on Helene! I keep on finding new stuff to post. This time it is a really cool montage assembled by Ian Regan.
Pointing at Helene
I posted already some neat images from Cassini's flyby of Helene last week, and commented on how most of the images from that encounter missed Helene entirely or only caught the moon at one edge of the camera field of view. Here's an example of one of those images.
Cassini's Helene flyby
I was much anticipating Cassini's encounter with Helene on Wednesday.
Calypso coolness
Cassini got pretty close to Calypso yesterday, on the way in to Mimas. Calypso is one of the smaller moonlets of Saturn.
