Opportunity looks down the cliff
Opportunity is continuing its circumnavigation of Victoria Crater, examining each picturesque cliff and possible entry ramp. This Navcam panorama was taken on sol 1,129 as Opportunity stood on a promontory between the Cape of Good Hope and Cape St.... More»

Io erupts, in color
The last one of New Horizons imaging instruments has finally checked in with a lovely image from the Jupiter flyby. I've already shown you plenty of images from the high-resolution LORRI camera (see, for example, this one, and these). I talked... More»

Recovering the recovered Pioneer data
I've just posted an update on the status of the Pioneer Anomaly project, written by project director Slava Turyshev, in which he reports on the work they've been doing to recover the Pioneer data from the recently recovered data files. It's a dry... More»

Infrared map of Jupiter
Most of the images that we've seen of Jupiter from New Horizons have come from the LORRI camera. These images are produced in a way that's very easy for the layman to understand: the spacecraft frames a target and takes a picture on a square CCD in... More»

Pan and Daphnis, seen together
Here's a cool recent photo from Cassini. I'm not aware that Cassini has been able to take a picture of Pan and Daphnis in the same frame before. Their orbits lie quite close to each other -- only about 3,000 kilometers separate them -- but because... More»

Spirit's cleaning event: The view from space
Last week I wrote about a new tool put together by ESA to allow online viewing the Mars Express HRSC image set called HRSCview. Rover enthusiast Daniel Crotty naturally pointed HRSCview to the Columbia Hills to see what Spirit's landing site looked... More»

Chemistry and Physics Suggest a Soup Under Enceladus' South Pole
I've just posted a news story on just two of the dozens of exciting science stories that are circulating about Enceladus right now. Both studies try to get at what's going on inside the little moon: one says there is (or was) catalytic chemistry... More»

Enceladus is a drag on Saturn's radio emissions
Just last week, I answered this question on my Q and A segment for Planetary Radio: "What does the length of a day mean for a rotating ball of gas like Jupiter?" (It was part of the Rosetta show with Gerhard Schwehm.) In my answer, I explained... More»
