The
MRO team seemed determined to make a good first impression. They came
into the arena of public opinion brimming with enthusiasm and glasnost,
proud of their mission and eager to please. Unlike Some Other NASA
resources, they solicited feedback and suggestions and
promised to deliver results promptly. Their releases , after
the inevitable delays any new project encounters, were even ahead of
schedule. The images were every bit as good as anyone had predicted.
Unfortunately, they were almost too good.

: This particular one isn't quite as sharp as one might think it
should be, since it is from a supposedly full-res close-up (what they
call a "cut out"). Interesting, though. Rotated left
from the posted orientation so you can see the cast of
characters a little easier. Notice the arch at
the top- and the face next to it. Click HERE

Because
of the high resolution of the images, they were very, very big. Previous
missions had not routinely posted the actual full-size images to the
public archives for just that reason. Even the images from Viking were
available on back-channel, intended-for-Scientists archives in much
larger formats. I know that one because I accidentally found some of
those years ago . JPL had built in a shortcut to the big versions on the
regular archive, which involved ignoring the download instructions.
Anyway, this does not contradict what I said before about "no
secret archives", because they weren't different, just bigger.
But let's stick to topic.
The
MRO people had discussions on this issue, and posted the notes of the
meetings on their blog. They voted, and by a split decision, decided to
switch to the JPEG2000
(usually called jp2)
format for the releases, as the files were getting too large for the
regular JPEG format. The science-beloved high-resolution TIFF and
PNG
formats would yield preposterously huge files. So the jp2 wavelet
compression format, a civilian cousin to various arcane
formats used in the geosciences, seemed like a good choice.
| I am
explaining this, by the way, because most people, including probably
most of you reading now, never see any space pictures other than the
Press Release ones. Relatively few "civilians" actually personally download images from
NASA archives, or care anything about file formats. I meet people constantly who ask, "Where did you get
this? They have no idea there even are public archives. So the word
enhancement
would be assumed to refer
to some sort of cosmetic surgery. Back
before the Internet existed, space fans could actually order custom prints of
space images from NASA. They do want you to look at their stuff. After
all, you paid for it. But do not expect NASA to show you what is
really there, 'cause then they'd have some
'splainin' to do, as Ricky Ricardo put it. |

The
MRO team has continued to introduce improvements to their website,
trying to make it more user-friendly, and now the curious can select a small area of interest on one
of the huge pictures and then view it at full resolution. But if you
want your own copy of the original, well, some of the images are over 2
gigabytes in size- in the highly compressed jp2
format ! This translates
to more than twice that, at a minimum, when you try to open the file,
which is larger than the hard drives on my first three computers were.
OK, so you have a huge hard drive, you say? The problem is this- the jp2
format was not designed for nor tested with such big files. The
available viewing software sometimes doesn't even work. So the website
is friendly, but the files are problematical. Thus far, therefore, most of those full-size MRO images are inaccessible
to most people- not impossible, but more effort than most people will be
willing to put to the task. That's OK, they may want you to look, but in
the best NASA tradition, they don't particularly want you to mess with
them (almost any image enhancement technique will involve upsampling,
which results in an even larger file). Take what's offered and be quiet. Let's assume (and hope) that this is not some
stealth method to keep the good stuff away from the peons. The evidence
on their website is that they are doing everything possible to make the
data public-accessible. In any case,
the reasonably sized JPEG "browse" versions are still often the equal of most of the earlier mission High-Res images. And maybe someone will
eventually write some better consumer software to handle this
problem. Meanwhile, you can always grab the RAW format image strips
from the archive and assemble them yourself. Right, that's going to
happen. We already talked about this in the last chapter anyway.

A
little piece of PSP_004981_1435, from the small version of
the image. The JP2 file is over a gigabyte in size, too big for
me to use, sorry. This is one of the extra images
added to the archives outside of the regular releases. The
description merely calls it an "unusual feature". This
represents maybe 5% of the area on the posted image, so I am not
sure where the unusual
part is supposed to be. |

Here's
part of PSP_004089_1065, down at the bottom, though this view is
rotated. Don't worry- that feature at upper right here is easy
to spot. I was initially thinking how much it resembles a number
of similar features that appear on MGS images, and then I
realized it also resembles in some ways the Cydonia Face complex
(now that we know what that really looks like). Which, of
course, means a whole new bunch of stuff to investigate in the
search for patterns. Sigh. Why don't they just tell
us, already? Thumbnail below, close-up, you know the drill... |

As usual, you
can generally see more in the long view, but close ups are
important , too. Some might actually be interested in how the structural design
works. Not particularly easy to figure out, but interesting
nonetheless. |

The
short answer
to why I spent so much time on this topic, despite the fact that I am
not weaving the MRO people into any new part of the Conspiracy: to explain why there are few
examples here of entire MRO images, or even large sections. I use small
segments of the full-res originals when I can, for close-in details, but
for wider sections, the files are simply too big for me to work with.
For some that my resources can just barely handle, the results would
have to be reduced so much, or cropped to such a tiny piece of the
whole, that it makes more sense to start with the small versions. A
related issue is the selection of a target zone on a raw image. I have
gotten fairly good at that, but you really cannot tell what is going to
be revealed by enhancement, so it is better to start with a larger area.
The esa and MRO images may be "honest", in comparison to the
tweaked earlier pictures, but the best features are not usually obvious
on the originals. Images like the Coprates Catena image shown earlier
are not the norm. Once you get a sense of what is really there, it all
becomes easier, but I am still constantly surprised. Speaking of having
to use the smaller version to enhance the majority of an image, here
is the MRO Face. Yes, I know it's a little dark. I had to leave the
saturation fairly high to accent the detail, and because...Where Is My
Monkey !?!

Given
the mutable nature of the tolas designs, it is not surprising
that different views of the same location show different things.
After all, this was the most perplexing and infuriating aspect
of Mars to the Insiders from the very beginning. But to
establish any sort of claim of evidence, there has to be
some repeatability demonstrated. Fortunately, the framing of the
MRO image is close enough to compare with the MGS one on the
previous page, even though the perspective is slightly
different. |

I'll
just concentrate on a couple of things. You can see the
Martians in the upper right and lower left corners (or, the
skeptic will say, the lumps I am imagining to be Martians). They
typify a Cydonia feature I have not pointed out before. On
all
the various dioramas revealed by all
the diverse combinations of angles and filters and cameras used
to photograph Cydonia over the past 30-plus years, all
the nearby figures are always
pointing toward the Face. It may be on the edge of the group of
structures there, but it is still the focus of attention.
You have to get a fair distance away before that situation
wanes. Now we just have to figure out why.
Continuing
with the comparison: if you look closely, the stressed out
ladies from the MGS image are just visible, though not distinct
in color here. The monkey should be right above that little
hook, but is not clear at all. To me, this indicates he is not
as three-dimensional a form as he appears to be on the other
image, but a tolas that relies on a specific light angle to
show, just like the color of the female faces. Not really a
surprise, but it is striking how defined he is when you can
see him. I told you there is a lot of glass (and refractive
effects) involved. I see enough other correspondences with the
contents of other Cydonia images to validate this one, but
I am not going to fill six more pages with them here. Even if it
did not bore you, it would bore me. You will have a much more
entertaining and enlightening time doing the cross-comparison
yourself, I think. There is a certain separate fascination in discovering how
one picture can agree point by point with several others,
yet not always the same points. It is somewhat of a mathematical
metaphor- in some advanced mathematical models of the Universe,
you need eleven dimensions to fully describe everything, yet to
define any individual specific thing, you only need to use six.
But not always the same six, thus the need for a bigger toolbox.
Who knows? Maybe that is one of the messages here. |

Here's
a close up look at the area. To look for the specific tolas
discussed above, you'd have to walk back halfway across the
room. But the detail is interesting. This is the thumbnail, the
great big version awaits your click. The extremely attentive may
be able to tell where the faces visible on the
"monkeyview" are, though different things are visible
from this angle. |

Here's
the less-noticed of the two circular features near the Face. No
one seems to have named it, so I call it the Hubcap. From PSP_003234_2210br |

Looks
like something from a Tomb Raider level. I suppose that fellow
is waiting for Lara Croft... |

From
the full JP2 version. Oddly, the browse version seems to yield
better results (certainly better color), although the full one
has more detail, especially in those three "windows".
There are really fascinating faces, with some wild tolas action,
in them- but so far I am not satisfied with the enhancement
results, so there is no close-up worth posting yet. Sorry. It
almost seems like the Cydonia Curse, but once again we have a
file that is not as good as it should be. The MRO people have
commented that 3234_2210 is not their best, either, so maybe a
reshoot will happen eventually. I just hope they include the
Hubcap and that other round feature in full when they do. |
