'Welease Wosetta!'

Suddenly a clamp has gone on to the Rosetta Comet missions video data with the ESA team demanding a proprietary period.

Fred - as you know we have a proprietary period on Chandra too but I think for planetary encounters it's a bit of a different situation. I think it would be a reasonable approach to release in real time jpg images with no metadata - which you can't do publication quailty science on - and keep the science grade data proprietary. (Actually I personally feel we should do this with Chandra and other missions too).

Last images they published are 5 days old. New ones should now be much better. What the...!

Do they find the images embarrassing? Does the comet not look like a rubble pile which they have always said that it is? Are there jets?

What's the world coming to? Spin doctoring in science...

Images so far are from the Navcam, which is a Star Tracker, built by the same folk who build nearly all the similar devices used on most probes. So what are they seeing from Rosetta? Is it UV or IR? Certainly not visible wavelengths out there, it will be as black as a coalies arse. I geuss they will leave it white as it suggests that it is a snowball type object. Star Tracker cameras can only be used on very dim objects due to the nature of their design.
The specifications do not mention anything about wavelengths, so it is likely wideband, no filtering.

The NavCam for the Rosetta mission was designed and built by Galileo
Avionica, building on a heritage of existing models, to satisfy the
requirements of the Rosetta Autonomous Navigation Component.

It was only begining with Clementine that the Military allowed some of their technology to be used on civilian missions.

More images due tomorrow according to the site 4real linked to:

This is an outrage that they would refuse to give us images of the comet at this time.

Here is the best image they have given us so far, which was the narrow angle cam; I have interpolated it crudely and then used unsharp mask to bring out as much detail as possible. Low quality navcam images just won't do it for us.

A larger size version of this pic is where I derived my data for. This image below is an "original" of the narrow angle camera.

Shouldn't that be "Wewease Wosetta" to parody "The Life of Brian"?

Well, here is another navcam image that they have deigned to give us. I have sharpened it for increased visibility of features.

Oops! Here is the processed version:

Here's what I could find about the comet. Again, they are hiding the best data and that's just wrong.

Here is the official picture and of course my processed picture.

Edit: the processed picture is the top one.

Sorry about that, that's just how it came out.

Okay, I found a 'hidden' Narrow angle camera image of the comet.

First temperature of the surface came in at -70C, much warmer than predicted. The nucleus is now said to have a dark, dusty surface too hot to be covered in ice. Shocker, eh?

I'm not surprised at the much higher temperatures. Comets are just asteroids under great electric stress, that's all.

Here is the latest Navcam image from Rosetta and of course my processed version.

Looking like another object with an oversize crater at one end, which did not destroy the icy rubble pile. Amazing how that happens. And the waist is suggesting a z-pinch?

Here's the comet at 1000km distance using the NAC:
