You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

Asteroid Steins Flyby

Asteroid Steins

Asteroid Steins seen from a distance of around 800 km by Rosetta. This tiny asteroid is only around 5 km at it’s largest dimension with a crater on the top right that is approximately 1.5-km in size. That is a large impact for such a tiny body, but we have seen small bodies survive such large impacts before (Phobos, moon of Mars for instance). It seems like a pretty typical asteroid thus far and joins the growing family of such bodies visited by we humans. As a matter of fact, if I didn’t know where this came from — I would have assumed it was just another tiny moonlet imaged by Cassini in orbit around Saturn.

See the flyby animation on the official ESA Rosetta site. For those keeping score… the next major encounter in our Solar System is in just about a month with another Messenger visit to Mercury.

    It’s a real shame about the narrow-angle camera.
