I figure that it is time for another thread like this. I still find it astonishing to see the versions of a lot of images that are reproduced over and over again. For example, this is the last mosaic of Triton taken before the close encounter began. The version on the Planetary Photojournal is on the left, my version on the right. Clearly, this image was produced as part of the "instant science" campaign. They did a superb job getting images to the public in a speedy manner, but they are extremely rough, since the team was busy running the spacecraft. However, it is this version that keeps being recycled. Worse, the version on the photojournal is clearly scanned from a printed copy, causing further degradation.
Here is a similar comparison, this time using Proteus (still 1989N-1 on the Planetary Photojournal!). This discussion started in the thread about Viking crescents but was getting off topic, so I thought I would start a new thread here. -------------------- |

I would agree - Stefan, you're not reading what Ted has posted in response to your initial scepticism and doubts. To be honest, my patience would have evaporated long ago.

This is another image that I find interesting. I have always wondered why some areas, even under low solar illumination, look very smooth on a fine scale, while some areas do not. I had always faulted the image data, but given the smoothness of portions of some of the small Saturnian moons, I have come to question that.
