I sincerely hope that you haven't joined ATS just to post this.
As I asked before, what's the problem with PNGs converted to TIFFs?
They were all probably converted to PNG or directly to TIFF (in the other cases) from the format used also in other space missions.

I will ask you one more time, since you haven't answered yet.
What is the problem in converting from PNG to TIFF?
(including those who believe in 10 years old Obama witnessed Apollo splashdowns in the middle of Pacific from Stanley's shoulders).
OK, I will answer that.

Please let us know which question you want to be answered:
No, I am not interested in personal, departmental or organisational problems of editing PNGs before conversion to TIFFs, because we do not know if there was any editing done. As far as I have seen we only have proof of format change.
Do NASA subcontractors have the problem of editing PNGs before conversion to TIFFs?
I don't know what you mean by QA.
Do NASA outsourcing management have the problem with QA?
I am not interested in that, and, as I said, being converted from PNG to TIFF does not mean that the images were edited in any way. Unless I am missing something.
Do public media have the problem by presenting links to TIFs and further edited JPGs as a proof of something?
Who cares? I thought the discussion was about the images presented this month, not about someone's childhood memories.
Do Barack Hussein have childhood memory problems related to Apollo program?
Who cares? I thought the discussion was about the images presented this month, not about someone's childhood memories.
Do NASA enthusiasts have a problem of finding a photo of 10 years old Obama, as they believe in his waving American flag to Apollo capsules brought to Hawaii?
What do you mean by that? I never had any problem converting PNGs, either from TIFF, GIF, JP2000 or CUB.
Do you have a personal problem while converting PNGs?

Maybe you would be taken more seriously if you removed this particular chip from your shoulder.
You seem to be asking a serious question (about arcane things that I don't understand, such as image file formats) but you toss in this canard about Stanley Kubrick (I'm assuming you are referring to the now deceased Mr. Kubrick, and not some modern bloke with a screen name 'Stanley Kubrick'???

OK, maybe I should rephrase the question, it looks like I am having problems (again) in making myself understood by other people.
My question is:
Does the fact that those files were converted from PNG to TIFF pose any problem with the files themselves?
Or, in another way:
The fact that the TIFF files do not come directly from a IMG or CUB file but from a PNG file affects their capability of reproducing what the camera "saw"?
Or:
Does the fact that those files were PNGs before mean anything besides a file conversion?
I hope you understand my question now. What I want to know is why do you (apparently) find the conversion from PNG to TIFF so important.
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the lunar surface that resemble channels. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length. However, the term has also been used loosely to describe similar structures on a number of planets in the Solar System, including Mars, Venus, and on a number of moons. All bear remarkable structural resemblance to each other.
*****
Structures
Three types of rille are found on the lunar surface:
Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface. Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille.
Arcuate rilles have a smooth curve and are found on the edges of the dark lunar maria. They are believed to form when the lava flows that created a mare cool, contract, and sink. This are found all over the moon, examples can be seen near the south-western border of Mare Tranquillitatis and on the south-eastern border of Mare Humorum.
Straight rilles follow long, linear paths and are believed to be grabens, sections of the crust that have sunk between two parallel faults. These can be readily identified when they pass through craters or mountain ranges. Vallis Alpes is by far the largest graben rille, indeed it is regarded as too large to be called a rille and is itself bisected by a straight rille; Rupes Recta in Mare Nubium is a clearer example.
Rilles which show more than one structure are termed hybrid rilles. Rima Hyginus in Sinus Medii is an example, initially formed through a fault and subsequently subject to volcanic activity.
Formation
Precise formation mechanisms of rilles have yet to be determined. It is likely that different types formed by different processes. Common features shared by lunar rilles and similar structures on other bodies suggest that common causative mechanisms operate widely in the solar system. Leading theories include lava channels, collapsed lava tubes, near-surface dike intrusion, nuee ardente (pyroclastic cloud), subsidence of lava-covered basin and crater floors, and tectonic extension.

AS TO Apollo 15, and those photos of Hadley Rille area, the vicinity in which they landed, perhaps some more information is in order:
OK, I understand what happened.

That is why
I don't need to wait until 2020, I already know some things about graphics formats, and to learn more I just have to look for the right information. Now with this Internet thing it's even easier than it was when I was in school.
As for your (apparently genuine) interest in graphics formats and image processing, you have to wait until 2020 as Obama said about college education.
That is not my interest at the moment, I just want to know why the conversion from PNG to TIFF is presented as something suspicious or wrong.
This thread is not about education in graphics tools and I am not in a position to assist with your (apparently genuine) interest beyond the topic.

You should perhaps also mention that the three images you posted links to were taken PRIOR to the landing, so people don't start looking for the LM or Lunar Rover tracks in the images...
Unfortunately no evidence of the Apollo 15 landing is visible in these images of the area which were taken as the LM lifted off from the landing site...

The Japan Aerospace Exploration Agency (JAXA) reported on the "halo" generated by the Apollo 15 lunar module engine exhaust plume that was detected in the data from Terrain Camera (TC) image, as of May 20th, 2008:
www.jaxa.jp...
Lets compare with photos taken from Apollo 15 before Moon landing from archives and recent LROC image of A-15 site as of July 17th, 2009:
So, Apollo enthusiasts have to choose options:
1. The dust have not been blown away during A-15 moon landing and that notorious japs Kaguya images are not correct (but Pokemons are for real).
2. The dust have been blown away and Japanese are correct and then in 2008-2009 season the dust somehow returned to A-15 site (but fortunately all other A-15 moon site historical sightings have been preserved).
