[fieldmarshaldj]

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

[cripplecreek]

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.

There’s a hole in the bottom of the sea,
There’s a hole in the bottom of the sea,
There’s a hole, there’s a hole,
There’s a hole in the bottom of the sea.

What created this unusual hole in Mars?

It was an accident! I tripped and fell, all right -- ?!?

There’s some salty talk on this here thread:

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

[cripplecreek]

I’d like to cover one and let some heat build up to see what happens.

[Jonty30]

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.

[danielmryan]

You mean it's not man's fault??

[fieldmarshaldj]

Uranus is a very interesting place. Maybe I’ll get to explore it up close and personal one day.

[Happy Rain]

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.

Well, there's only one solution then: ban time travel ;)

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

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.

There’s a hole in the world tonight
There’s a cloud of fear and sorrow
There’s a hole in the world tonight
Don’t let there be a hole in the world tomorrow
