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.

that’s the white side of Obama’s family passin a bit o wind
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.
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.

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.
I’d like to cover one and let some heat build up to see what happens.
It would be a nice project, but you’d have to oxygenate the hole, otherwise there will be no fire.
...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.
Uranus is a very interesting place. Maybe I’ll get to explore it up close and personal one day.
To the Left this hypothesis would have legs.
Well, there's only one solution then: ban time travel ;)
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
