Thanks, mikesingh.
As these images have a 26.7 cm/pixel resolution, this feature is some 24 metres long by 8 metres wide.
This is the full sized IRB version.
The IRB images are not true colour (or even approximate true colour) because they are made with infra-red, red and green+blue filter instead of red,
green and blue.
This is the RGB version.
Although called RGB, these images are not really created with red, green and blue filters because the camera is not equipped with individual green and
blue filters, it has only a filter for both green and blue. The RGB images are created by using a synthetic blue and the green+blue filter as green.
The synthetic blue is create by multiplying the values of each pixel from the green+blue filter by 2 minus 30% of the values from the red filter.
As they say
here (from where I got this information):
"This is not unique data, but provides a more appealing way to display the color variations present in just two bandpasses, RED and BG."
And this is the grayscale image from the red filter.
Mikesingh (or anyone else), if you want to look for strange features, "anomalies" or just look at those photos I suggest that you download IAS
viewer (link available on the bottom left of
this page) and use it, it has many good features and it
allows the viewing of the JPEG2000 files online, downloading only the area we are looking at.
Those JPEG2000 files are the only files available at full resolution. The image you use is only 2048x10345 (including the title) while the full
resolution JP2000 file is a 12952x64193 image.
That sure looks like a buried spacecraft like that one on the Moon (Apollo 20). I've tried enlarging it further to see what it looks like.
Note that 'bubble' on the nose cone.
