The far side of Phobos
Now here is an unusual image of Phobos, Mars' moon. We are looking onto the side of Phobos that faces away from Mars. ESA's Mars Express is the only spacecraft currently in Mars orbit -- the only one since the Viking orbiters -- that is capable of... More»

Soviet landers Luna 20, 23, and 24, plus the tracks of Lunokhod 2
Today is the bonanza day for Lunar Reconnaissance Orbiter: the first formal release of orbiter data happened this morning, including 10 Terabytes (that is 10 million Megabytes!) of camera data. I am in the middle of writing a lengthy post on that... More»

Phobos from Mars Express
ESA has released the first image from Mars Express' recent close flybys of Phobos, posted below! For a little review on Phobos' geography and why Mars Express is uniquely suited to imaging it, check out this earlier blog post on some of the many... More»

LPSC: Wrapping up Tuesday: The Moon, Mars, Mercury, Vesta, and back to Mars
Well, it's already mid-day on the Friday a week after the Lunar and Planetary Science Conference ended and I'm STILL not done writing up my notes. In the interest of moving on to other things, I am now posting pretty much everything I have left,... More»

Pretty pictures: Europa from Galileo and Voyager
For some reason both Jason Perry and Ted Stryk took it upon themselves to produce new, pretty versions of Jupiter's moon Europa this week, so I'm hereby featuring them! Europa is picturesque and strange both from a distance, as seen by Voyager, and... More»

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, another one of the amateurs who hangs out on unmannedspaceflight.com. Unlike Ted Stryk and Gordan Ugarkovic,... More»

Unbelievably spectacular flight through Candor Chasma
This is one of the things that came out during LPSC last week and all I could do at the time was Tweet it, which doesn't serve most of my readers, I realize. So here it is in blog form: the most unbelievably spectacular 3D animation of a bit of... More»
