The 126th Space Carnival is live over at Jason Perry's always-excellent (if rather narrowly focused) Io blog The Gish Bar Times.

Here's a neat animation captured last month by Cassini and assembled by Mike Malaska: spokes in Saturn's B ring.

So many goodies on the Cassini raw images website lately! I am especially excited when Cassini takes photos through red, green, and blue filters so that it's possible to create views that look roughly like what you'd see with your own eyes.

Checking in on Cassini's raw images this weekend, there are several nice shots to play with, including the many frames from which I tossed together this cute animation.

Opportunity's been making tracks lately, with brief stops to check out a couple of meteorites. I thought this view of its surroundings on sol 2,034 (a couple of days ago) was neat.

I was debating whether to write anything about a reported fireball that streaked across the sky in the Netherlands at roughly 19:00 local time (17:00 UTC) yesterday, October 13, but seeing this image ended my internal debate.

Advance warning: this entry may be a little technical for some.

Unmannedspaceflight.com member Astro0 was fiddling around with an interesting-looking sequence of Cassini images when he discovered their purpose -- they were gathered in order to see if Cassini could catch aurorae flaring into being near Saturn's north pole. Cassini sure did!

Quite a night! I set my alarm for 3:15 am in order to get up and watch LCROSS crash into the Moon.

I wonder if this came from the same original body as Block Island, or if Meridiani is the kind of slowly deflating landscape that accumulates meteorites at its surface, like the ANSMET meteorite hunting spots in Antarctica?

Opportunity rover is driving, driving, driving. It departed the meteorite named Block Island on sol 2,004 and has routinely clocked 70 meters per driving day (with drives every other day).

Doug Ellison has done it again: he's created a spectacular overflight of Gusev crater based upon digital elevation models of the terrain produced by the United States Geological Survey from HiRISE data.

Just a cool image to start the morning: after a 70-meter drive yesterday, Opportunity's following not one but two sets of its own tracks.

For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.

While Spirit has been stuck at Troy, it's been taking numerous opportunities to capture photos with dramatic twilight lighting. On sol 2,002 (three sols ago, or August 21), it gazed toward the setting Sun, snapping the shutter roughly once a minute.

The Cassini spacecraft made its 59th flyby of Titan, Saturn's largest moon, on Friday, July 24, and in the last few hours we have received images from the RADAR instrument in SAR (Synthetic Aperture Radar) mode.

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.
