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?

"It's deep, and it's big; the hole that we see really is just a skylight on a big subterranean room. How big?"

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

Then shouldn’t it be deflating like a balloon?

This is guaranteed to get the UFO bugs worked into a lather.

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.

"This is guaranteed to get the UFO bugs worked into a lather."

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

Let’s just hope they don’t begin to multiply.
