Windows onto the abyss: cave skylights on Mars
Planetary Society ^ | 5-23-07 | Emily Lakdawalla

Posted on 05/27/2007 1:21:33 PM PDT by Renfield

Today's set of image releases from the Mars Reconnaissance Orbiter HiRISE team included this one, of a fairly bland-looking lava plain to the northeast of Arsia Mons. Bland, that is, except for a black spot in the center. What's that black spot? It's a window onto an underground world.....

What are these? Sinkholes? What are the diameters?

The entire planet is hollow. This is just a hole in it.

Cave entrance on the flank of Arsia Mons At its highest resolution of 25 centimeters per pixel, the HiRISE camera can see the detailed shape of the slightly scalloped edge of a hole on the flank of Mars' Arsia Mons (left), but no amount of image enhancement (right) can bring out any further details inside the hole. That means that the walls of the cave are overhanging -- the cave is larger below the ground than the entrance we can see at the surface -- and that it is very deep. Mars' dusty atmosphere produces enough scattered light that "skylight" would illuminate the floor of a shallow cavern well enough for HiRISE to detect it. Credit: NASA / JPL / U. Arizona

A 100 meter black hole on Mars? I would be more inclined to believe that the HiRise Team blacked this crater out for some unknowned reason.

This proves MARS is hollow and all the martian aliens and spacecraft hide inside waiting to overthrow the EARTH!

Remember when some nuts thought the earth was hollow and flying saucers came from there?

That is a very round hole, and no doubt it was perfectly round at one time, shortly after the mighty launch of a spacecraft of obviously huge proportions which carried the survivors of the great Martian apocalypse. I wonder where they went?

This looks like a bullet hole in a piece of blotter paper.

As far as I know, the Planetary Society is a legitimate organization, but I sure am suspicious of this photo. It makes the surface of mars look as thin as an eggshell.

Sure is. Also, fun for comparisons with some science fiction movies and series such as B5 and the Shadow vessel dug up on Mars.

We assume the light from the sun and the camera are right above the whole. If the light is at an opposite angle as the camera, the whole could be shallow and the same effect would occur.

I don’t know. It looks like a black spot on the picture! It seems that it’s too perfectly round. Just a glitch with the camera?

Worth examining in depth. The South Pole-Aitken Basin on the Moon has an apparant impact crater 12 km deep - more than seven times as deep as the Grand Canyon - and 300 km wide. It's by far the deepest impact crater in the solar system.

This may have been the pivot point for a massive boom-arm used by ancient space-farers to fling carbonaceous chondrites mined from Earth's surface to the vicinity of what is now called the asteroid belt.

All connected guys ~ caves with skylights, pivot points, mining residue, except that all this stuff is 3 billion years old and the detailed remains have withered away into space dust.

Suspicious ...looks more like a touch up job to blot out something the public is not supposed to see. Look along the left edge of the enhanced ... OTH a solidified then indented pool of oil would allow for the same effect of light absorption, wouldn’t it?

Interesting, but I would need to see several more images of the exact same area, taken at different Sun angles.

Physically, these are crater chains in the images provided, and it does not make since how the larger craters would not punch a deeper hole into the surface than the little ones.

At the moment, I will label this as: Interesting, but most likely, only an angle of illumination phenomenon.

Note the pocket of black at the 11 Clock position. This might have some characteristic’s of a liquid filled crater. Anybody have a picture of a water filled crater on earth taken from a satellite? I bet the liquid looks dark.

Look at “D”. That is not a crater, it’s a high prominence with Sun high from two o’clock a shadow to the four o’clock.

Interesting that some of those holes are rather close to impact craters. If the impacts were after the holes were formed one would expect to see them caved in or perhaps even collapsed if such a large opening existed underneath...
if the holes came after the impacts then their origins could be fairly recent.

Many questions.

As Glenn Beck says: I'm no scientist but I am a thinker. Something is rotten on Mars. For one thing if it was a cave, If the sun was shining directly into it one would see the sides for a ways down. If the sun was to the right or left of it, one would see one side or the other for a distance inside.

Also the pictures of A and B, I detect a thin ridge or mountain on the right. If it had a round hilled top it would make the round shadow. The near craters have shadows on the same side as this one.

I believe it is a phony picture put on the web by Al Gore and in a week he will tell us that it is from the Global Warming on Earth.

On the "100 meter" pic, the irregularities at the top and bottom of the rim seem impossible... if it's a hole, they're just hanging in midair. It really does look like a lake of something dark.

OK, bad phrasing. By “top and bottom of the rim” I mean the (roughly) twelve and five o’clock positions where the rim meets the dark whatever-it-is. Sorry.
