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
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.
Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.
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.
I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.
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.
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.
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.
Just a pretty picture post, a dramatic Cassini shot on the outer edge of the A ring captured earlier this month.
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.
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.
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.
Here's a lovely picture whose components came down from Cassini a few days ago.
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.
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.
I was much anticipating Cassini's encounter with Helene on Wednesday.
Cassini got pretty close to Calypso yesterday, on the way in to Mimas. Calypso is one of the smaller moonlets of Saturn.
There were many, many treats waiting on the Cassini raw images website this morning. Yesterday, Cassini traversed the G ring, taking photos all the way.
The January 1, 2010 Cassini imaging data release includes everything acquired by Cassini from January 1 to March 30, 2009 in all its high-quality glory.
This one is fresh from the spacecraft! The data were captured yesterday, December 26, by Cassini during its best yet imaging encounter with the small ringmoon Prometheus, and showed up on the Cassini raw images website today.
