Massive Cave Found on Mars

Zonk posted more than 7 years ago | from the anybody-home dept.

Mars 310

mrcgran writes "Space.com is reporting a very deep hole found on Mars: 'The geological oddity measures some 330 feet (100 meters) across and is located on an otherwise bright dusty lava plain to the northeast of Arsia Mons, one of the four giant Tharsis volcanoes on the red planet. The Mars Reconnaissance Orbiter (MRO) used its High Resolution Imaging Science Experiment (HiRISE) instrument to draw a bead on the apparent deep hole — a feature that may cause more scientists to ponder about potential subsurface biology on Mars. Because the spot lacks a raised rim or tossed out material called ejecta, researchers have ruled out the pit being an impact crater. No walls or other details can be seen inside the hole, and so any possible walls might be perfectly vertical and extremely dark or — more likely — overhanging.' The original image and its cutout at full resolution can be found in the HiRISE site."

That's no cave! It a giant pool of Purity [wikipedia.org] .

Seriously though, the absolute absence of albedo in the visible spectrum is stunning. I wonder if there are multi-spectral images of this site? I expect this location will be of intense study in the future as there is little more than a complete absence of something to stir the human imagination.

However, I have to disagree with the analysis in that you can see shallow walls at the very edges of the crater if you stretch the image some and examine the profiles. It also appears to match the brightness of the elevation changes from one rim of the hole to the other which should give some idea for how tall the lip of the hole is to where the "blackness" starts presuming they know the angle of the sun and lat and long. Depending upon how far up the sun can get in the sky at a different season, there may be a possibility of seeing further into the hole, presuming of course it is not a giant pool of Purity.... :-)

Toad-san (64810) | more than 7 years ago | (#19425253)

Agreed. Well, maybe not the Purity contents .. but something apparently is on the bottom of a hole. Maybe a sinkhole, true, but still a hole. A sinkhole opening into a huge dark cavern would not have inward slanting edges, they'd be outward slanting (getting wider toward the bottom, where it caved in).

Hmmmm .. oil?

Oh oh .. don't tell this Administration that! We'll be invading Mars, and you know how that upsets the locals.

Smidge204 (605297) | more than 7 years ago | (#19425709)

From the summary: "No walls or other details can be seen inside the hole, and so any possible walls might be perfectly vertical and extremely dark or -- more likely -- overhanging."

If you look at the image more carefully, you can clearly see shades and highlights that suggest the terrain slopes into the hole all around. That pretty much excludes equipment faults. One possible theory is that the cavern is conical in shape, getting wider as it goes down, which would certainly explain why it's so dark.

Also remember this picture is taken from a satellite. I'm sure they'll be taking more as soon as they get an opportunity.

We've a photo that shows soemthing that might be a hole in the ground. If people went to Mars then they could live in the hole instead of on the surface... don't think that's a /. story. But:

I'm no geologist but possibly is the story how the hole was made ?

Because the spot lacks a raised rim or tossed out material called ejecta, researchers have ruled out the pit being an impact crater.
So that leaves wind(?) , water(which would be a story) but a big river at 330 feet across, X ? , Y? , Z ?. What might make this story would be some informed geological speculation. Otherwise someone has just found a hole in the ground.

It's a slashdot story because it proves Mars is a cleverly conceiled Death Star type spacestation, constructed by George Lucas.

Not wind, because the surface appears to be fairly flat, and I'm not aware of wind ever punching a hole straight down into the surface like that (at least not without other nearby protrusions to force the wind into some sort of vortex). Not a surface river, because there are no flow indications on the surface. Possibly a subterranean river or something which has eroded the material from the surface, leaving behind a thin crust on top. An impact would then break through the surface and not scatter ejecta around. But what exactly caused the erosion of the subsurface material?

NO one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable. It is curious to recall some of the mental habits of those departed days. At most terrestrial men fancied there might be other men upon Mars, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us. And early in the twentieth century came the great disillusionment.

There is so much to know about Mars that we don't.

No light is reflected back, which is kind of spooky. What can be inferred about the depth? How deep would it have to be for the HiRES camera stop sensing the light that is reflected?

It's nice and round, that's unusual. There is no crater ejecta so I'm guessing nothing hit it. I'm not a geologist, but aren't giant round holes in otherwise homogeneous flat terrain a bit uncommon?

Is there any radar in orbit with enough resolution to bounce a signal down one of these? I'm just so full of questions and awe.

Re:Oh man (5, Informative)

PFI_Optix (936301) | more than 7 years ago | (#19425727)

Y'know, if the UAC would follow a few simply rules of planetary colonization, they wouldn't have such problems.

1) When your life depends on the structural integrity of your base/space station, keep it well lit. Dark corners and unlit passageways invite unobserved problems and make excellent hiding places for demonic hordes.

2) Emergency lighting is your friend. Self-contained lights that can run off batteries for days have existed since the 20th century. USE THEM.

3) Teach your space marines how to use a pistol and flashlight at the same time. Television actors pretending to be cops can do it, so can they.

4) Keep hidden compartments, passageways, and crawlspaces to a minimum. This will drastically reduce construction and maintenance costs by keeping the design simple, and make it far easier for a lone marine to save all of humanity.

5) Develop lockdown procedures. They're useful in the event of a sudden loss of pressure to prevent your entire base from leaking air out a single fracture. They can also come in handy when your absurd experiments fail and you find yourself surrounded by blood-thirsty monsters. Seal all the doors. Combine this with #4 so that they can't simply bypass the doors by crawling through unnecessarily large ventilation shafts or open ceilings.

Why is it so hard to believe that there is a massive cave under a lava plain? 300ft isn't that huge considering the other features on this planet. If the hole opens to a larger underground area...the light may not as easily reflect back up out of the cave. Think about it...if you have a deep cave that is 300ft wide and it opens up into a vase like structure...the light will have a dificult time reaching back out of the cave.

The article says that the lack of ejected material rules out an impact, but it certainly does not rule out an impact into the roof of a dome (likely a lava-formed dome given the material)... whether from space or from a volcano (any within several miles?). There'd be little to no kick-back of debris if it simply punhced through.

It could be a structural collapse, but it's awfuly round.

Obligatory "The Far Side" cartoon reference (slightly embellished):
Upon investigating further, scientists discovered a broken piano in the large black spot (as well as thousands if not millions of missing aircraft, broken computers, loose change, small animals and socks)... it turns out that the spot the sun never shines wasn't in Iowa! It was on Mars!

Well, now we know where to stick it where the Sun don't shine.

Lava Tube (4, Informative)

jnaujok (804613) | more than 7 years ago | (#19425745)

Given the fact that it's on the side of a volcano, and the fact that it's in the middle of a lava field, the most likely answer is that it opens into a lava tube [wikipedia.org] . Most likely a small meteorite hit the center of the circle and caused a circular fracture that fell into the underlying tube.

Or the ground just shifted... Or even better, someone took some white paper, and used a hole puncher on it, photographing it with a black background!

Deep enough? (1)

Dimwit (36756) | more than 7 years ago | (#19425755)

According to one source, they've estimated that the hole is about 130 meters deep.

How deep would the hole need to be to provide a reasonable atmospheric pressure at the bottom? I realize it wouldn't be *breathable* atmosphere, but at least the pressure would be survivable.

Any ideas?

Vacated worm home (5, Funny)

Clearly it's the vacated home of the Asteroid Worm in Star Wars: Episode V. He couldn't afford the rent anymore.

Cheers.

Miniature black hole? (0)

I know it sounds stupid - but could it be that it was an impact from a miniature black hole?

Nope because the whole planet would have been sucked in and probably Earth as well.

After a giant cave was found on the plains of Arsia Mons scientists called a press conference to announce they have named it Mons Veneris.

And then they spent the rest of the press conference giggling and nudging each other.

Subterrain Realestate (1)

OverlordsShadow (1034748) | more than 7 years ago | (#19425999)

When and how can I purchase some of this new found realestate. Was thinking it might be a good site for future filmings of Batman and other movies which may involve caves as Hollywood is usually willing to pay big bucks for prime locals.

"I am inclined to think that this blaze may have been the casting of the huge gun, IN THE VAST PIT SUNK INTO THEIR PLANET, from which their shots were fired at us."
Wow... H.G. Wells was ahead of his time.

You can see on the one edge, at about 11:00-12:00 on the "cave" edge, where there is a string of tiny islands in the black goop. Explain that to me in terms of a cave feature... good luck!
