Astronomy Picture of the Day -- A Hole in Mars
NASA ^ | July 18, 2012 | (see photo credit)

Posted on 07/18/2012 3:21:59 AM PDT by SunkenCiv

Explanation: What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image right. Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep. Why there is a circular crater surrounding this hole remains a topic of speculation, as is the full extent of the underlying cavern. Holes such as this are of particular interest because their interior caves are relatively protected from the harsh surface of Mars, making them relatively good candidates to contain Martian life. These pits are therefore prime targets for possible future spacecraft, robots, and even human interplanetary explorers.

I wonder... is there a hole in Uranus ?

Lava tube buried in the sand would be my guess. I know similar caves have been spotted elsewhere on mars.

Personally I think canyons and caves are the places we really need to look but its easier to land on open plains.

They are also good candidates for home bases, if we ever do manned missions.

It would be a nice project, but you’d have to oxygenate the hole, otherwise there will be no fire.

The near perfect circle and smooth contours suggests a direct hit by a comet traveling at such a high rate of speed it liquefied the ground and caused the “bouncing drop” effect one observes when a water drop falls in water...the final fall of the now partially cooled ball of Martian turf forming the cone while the still hot and gooey inner core collapses back into the depression to make the hole...

...just a guess-and if I am right the interior of the formation would resemble a domed stadium with a skylight--good location for shelter and terraforming.

Could be—perhaps Haliburtan developed a time machine star ship that allowed Dick Cheney to travel back to prehistoric Mars in time to divert the comet to smash into a herd of Martian puppies.

To the Left this hypothesis would have legs.

How on Eart...on MARS, did Neil Armstrong miss this last time he was there??

Image and video hosting by TinyPic

On a visit to the NASA Jet Propulsion Laboratory in 2005, Jackson Lee made embarrassing news by asking if the Mars Pathfinder had taken an image of the flag planted there in 1969 by Neil Armstrong.[2]

Prior to the 110th Congress, Jackson Lee served on the House Science Committee and on the Subcommittee that oversees space policy and NASA.

"The Land That Time Forgot"

"Negotiating an underwater tunnel [beneath the ice] to gain the island's interior, those aboard U-33 are amazed to discover a tropical prehistoric world kept warm by volcanic forces. Here dinosaurs that should be long extinct live and roam, as do a curious race of humanoid savages that appear to exhibit all the various phases of Man's evolutionary development. To survive long enough to repair and replenish the U-boat, wartime enemies must put aside their differences and cooperate with one another. But not everyone is playing from the Kumbaya songbook...

The Land That Time Forgot is a thoroughly old fashioned sci-fi/fantasy adventure of the type they weren't really making anymore even in 1975. A lot of this has to do with the script sticking to Burroughs' Victorian style. (His Caprona tales were first published in 1918; as late as World War II he'd still be cranking out novels in the writing style of the 19th Century.) The film's a throwback to the likes of the original King Kong and potboilers such as Unknown Island (1948) and The Land Unknown (1957), only in color."

Exactly what I was going to say. Once the lava passes through, it leaves behind a tunnel.

Time travel means you can be taxed for the same income earned at any particular moment over and over...

"Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep."

I really wish that US government agencies would quit expressing measurements in metric units. I understand that the base ten system is superior to our ancient English system of measure, but few Americans can really think with meters, liters, millimeters, kilometers, etc.

I watched a science program the other night, and for once, the commentators expressed all measurements in miles, pounds, feet, and inches. It was surprisingly refreshing, because I was able to visualize the quantities and scales involved with no effort.

As far as I know, the US hasn't officially converted to the metric system. My generation (boomers) didn't learn it in school, even though we had a basic introduction to it. I don't know if children in US public schools are learning it today. If the science community insists upon using it in their work, that's fine, but they should understand that they put the general public in a fog when they attempt to communicate with us, using metric terminology.

There have been so many discoveries of “new” (previously unknown) microbes in the past decade, microbes that have developed metabolic processes that defied previous understandings of “the essential ingredients for life”.

So, if I were any scientist I would be very careful about declaring any part of any other world as an area that cannot sustain life. All such claim can really apply to is “life as we know it”.

As we start to “explore the universe” I think the best expectation we can is to expect the unexpected.
