(edit)
moved the post into correct thread. (edit) Anyways, this was really an exciting mission to watch since it was so dynamic! |

The OSIRIS reference paper, posted here, says this about the wide angle camera: On <ahem> April 1 of this year, the OSIRIS team posted an image of the principal investigator taken by the wide angle camera’s ground reference unit at a distance of 15 meters: https://planetgate.mps.mpg.de/Image_of_the_...016-04-01a.html To my eye the test image looks less fuzzy than the actual final image, but the test image might not have been compressed, and of course the conditions and subject matter were different. Congratulations and thanks to the team, and to the people who wrote about the mission for us. I think you may be making an interesting point (prepare for lay-person reporting). I know nothing about imaging, but Holger did say yesterday that he was surprised that the last image was somewhat more in focus than the immediate predecessors. He seemed to say that they did not really know the effect of removing the filters and would need to look at this to understand the last few frames. |

There's no reason to think that their ground unit is focused identically to the flight unit, especially for distances well inside the requirements. -------------------- Disclaimer: This post is based on public information only.

Sleep well, Rosetta, we will miss you.
I particularly love this descent image Rosetta took (enhanced by Ted Stryk) Could somebody please "drop" an astronaut into this image, for scale reference, just like it was done with MSL pictures. -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

Could somebody please "drop" an astronaut into this image, for scale reference, just like it was done with MSL pictures. the pixel scale, according to ESA, is about 30 cm/pixel, so the astronaut would be about 6 pixels tall |

Someone already did this (the tiny red line is on top of the cliff). Somewhere there's a picture of this with the ISS to scale, but I can't find it right now. Phil -------------------- ... because the Solar System ain't gonna map itself.

These sharpened images (as well as Philaes descent sequence) show pretty nicely how the stuff which looks like sand from far away is more like rubble close up.

Inspired by the work of Roman Tkachenko I made this photo where I compare the size and details of the various photos in high resolution taken during the Rosetta-Philae mission. Great job! -------------------- |

And an unexpected final image was recently gleaned from the telemetry.

Sky@night article i must have missed that incredible Rosetta image taken on 7/3/2016, better yet, research deepens the mystery suggesting the plume is not mere sublimation of an icepack, but due to '..Possible scenarios include the release of pressurized gas stored below the surface or the conversion of one kind of frozen water into an energetically more favorable one.."

Excellent news! The images from the rest of the Post-Landing phase of the mission have been posted to the Rosetta archive. They include the final descent imagery.

Some mosaics assembled from the recent batch...

Very nice as usual! I think the lower right of this image has what I noticed back during the mission, a possible impact crater candidate (albeit almost filled in) and maybe the only one on the whole nucleus? It's much more circular than the other depressions. Plausible?
A little postscript to Philae: it is faintly visible in this image from August 30th, 2016. |
