Spectacular animation of Halley's comet
It's a holiday and I'm enjoying time with the family, so rather than write a lot, I will let a spectacular image do the talking for me. Here is an animation of data from ESA's first interplanetary spacecraft, Giotto, launched to study Halley's... More»

Saturn's aurora, even better than before
The Cassini imaging team have posted their own processed and captioned version of the Saturn's aurora movie that I posted a preview of about six weeks ago, and it was worth the wait. It turns out that the video covers an amazing 81 hours of auroral... More»

Two more awesome pictures from the Enceladus flyby
I'm getting to be a broken record here, but I can't stop looking at these photos from the Enceladus flyby. This first one I put together from two of the south polar plume images – you can see all four of the tiger stripes, and the plumes issuing... More»

Another great Enceladus shot
Here's a 4-frame mosaic of Enceladus images -- just another everyday spectacularly alien landscape.
By the way, if you checked the Cassini raw images website earlier in the day, you should return, because there are more photos from the Enceladus... More»

Prepare for your jaw to hit the floor when you see these pictures of Enceladus
Wow, just wow. I didn't know what to expect from the second flyby of Saturn's geyser moon Enceladus in November, which happened yesterday. I knew the cameras were given control of spacecraft pointing during the closest part of the flyby, so that... More»

Space Imaging II: Getting Started with MER and Cassini Raw Images now available for download
I probably crammed too much into today's class: an hour-and-a-half whirlwind tour through the cameras on the rovers and Cassini, how to access their raw images on the Internet, and some basic processing that you can do with each of them.
If you... More»

Hayabusa's still coming home: JAXA engineers come up with yet another creative solution
Ideally, you'd like to have a space mission that faces no problems. But in the real world, spacecraft run into trouble. Trouble has come time and again to JAXA's little Hayabusa asteroid sample return mission, yet the mission's engineers always... More»

Opportunity's poking at Marquette Island; Cassini's catching dancing moons
Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working... More»
