Regarding the OPs second video:
It is not a NAVCAM image from the 8th August, it is an image from the OSIRIS camera retrieved on the 6th August - original here:
blogs.esa.int...
Vertical scan lines have been added and the object superimposed, with the image being panned around to give the impression of movement.
The Navcam cannot even be re-orientated, it is fixed on the spacecraft.
The OSIRIS camera does not send a daily image, it is more like once a week. The Navcam images are daily images, they are composed of one image, not a
video feed, and therefore before even considering anything else would not be able to provide a sequence as shown. If you look at the Navcam daily
images you'll note that the comet's orientation is changed greatly, again rendering this sequence impossible.
THE real image from the Navcam on the 8th August is here:
www.esa.int...
In addition:
Data is downloaded from Rosetta at around 9 kbps
blogs.esa.int...
It would not be physically possible or viable to even acquire a sequence as implied in the video. This data stream has to carry all telemetry,
instrument data and image data. You're simply not going to get a video as depicted whichever way you look at it!
So to summarise the 2nd video:
1) Not a Navcam image from 8th August, it is an OSIRIS image from 6th August
2) The image has been zoomed in on and is panned around to create the illusion of tracking or movement
3) Scanlines have been added in
4) Only 1 image is taken daily, a sequence like this is not possible
5) The data rate is ~9kbps for all telemetry and instrument data - not exactly a video streaming connection!
As for the first video, starting with the letter itself.
1) "Spoofed through multiple anonymous proxy servers?" - Sounds like a hollywood description, there are plenty of of services which anonymise your
original IP and Tor is an obvious popular choice, which basically does exactly that. How was conclusion even come to? Sounds like BS if you know how
email routing works, you would just use something like Tor when accessing the originating SMTP server which records the IP address visible in the
header. Which email service was used? Can we see the full header? Was it sent through a web based client, is this what you mean? Was the email
encrypted? Does Secureteam have a public GPG key? Anyone leaking information would at least use this simple, effective system to ensure data is not
intercepted.
2) Why is the date of the email being received omitted from the screenshot? - I'll come to this later.
3) Not sure I've ever heard anyone from ESA say they work at 'the ESA' - while technically correct it's just not commonplace - though of course
this is a pretty meaningless by itself.
4) No one at ESA has a 'rank' nor would they refer to themselves as having one! It's not the military!
5) Rosetta hasn't just gone to take random close up images, while a lot of valuable science will be carried out from orbit for many the highlight is
the lander Philae, which will land on the comet in November to carry out experiments. No one from ESA or with any real knowledge in their right mind
would omit this from a mission description! Even most of the public know about and are excited about this!
Now the images:
1) The first image - There isn't a grid imposed on images from the Navcam or OSIRIS! This is originally from
www.esa.int... - a Navcam image from 5th August. And who the hell would
'sharpen' such a low resolution image? If you 'sharpen' any picture you could find Santa on your wallpaper if you look hard enough! You can click
on the full size link on the ESA page for the 1024x1024 image.
And if you doubt that the Navcam images at 1024x1024 then it is confirmed here:
starbrite.jpl.nasa.gov...
Only an imbecile would try and pick out tiny details and sharpen them for any serious analysis in such photos!
2) The second image - original taken by OSIRIS on the 3rd August here
www.esa.int.... The 'original' version in the video with the 'airbrushing
removed' looks like someone clicked with the blur tool!
Funnily enough, the 'feature' from the first image is also clearly visible as just part of formation of the surface and a shadow. No sharpening
required!
Of course, the lack of a date being visible on the email conveniently allows some leeway in 'adjusting' when it was received. So was it a scoop or
was it sat on for a couple of weeks before being brought to the viewers attention? Were this secret images already public when it was received? We can
never know now, all we do know is that the video was released on the 11th August almost a week after the images were available to everyone anyway.
It's obvious that these exclusive 'real' images in the video are faked, but other than using ones eyes and common sense it can't really be proven
realistically. Metadata can be changed easily, anything in retrospect now would be meaningless, I just hope that people are able to actually come to
the rather obvious conclusion.
