Limpets, Rubber Ducks and Cookies in Space

After my recent 'Dismaland' diversion, it's back to outer space - a new photo of Ceres reveals the mysterious mountain in greater detail.
The frustration increases, however, as we realise that this is the only close-up view we currently have, taken from some 900 miles above.
The strange mountain is also bizarre because it really is alone in an otherwise flat landscape, which is surely suggestive of an artificial origin.
I find this both fascinating and totally frustrating.
Frustrating because we won't get any more detailed images until December, when spacecraft Dawn enters a much lower orbit , taking closer shots from just 275 miles above.
Theories abound as to the nature of the 'mesa', with some saying it's material excavated from the nearby crater, and others declaring the 'spurs'  to be ice water.
The site has already been dubbed 'lonely mountain' by some Tolkien - lovers :
and I wouldn't be surprised if there was a dragon guarding treasure there...

Conjecture is all we have until further evidence arrives - I think it's amazing, especially given that our initial interest in Ceres was piqued by the highly reflective areas in what is now called the 'Occator' crater  - also still a mystery -
infact there has been a dearth of new information on that front, which has allowed exotic theories to abound.
There is conjecture that the mysterious 'reflections' are atop tall pillars which project above the crater edge ( giving us pillar / structures some two miles high)
An abandoned city / mining site has also been mooted - this is no longer such an outlandish idea , don't forget that we already have companies in place gearing up for offworld mining, after all.

Personally, I wonder if such ideas are being encouraged, purely to keep people interested in the otherwise quite 'dry' science of 'space-geography'.
Speaking of which, is there such a thing?
There should be, with the incoming data helping to create a database - after all, surely many of the oddities we are seeing arise because we try to make otherworld  geology match our own:
but our own knowledge is limited to this little blue planet.
Oh, and the moon.
Mars can be partly included as well, with Curiosity continuing its examination of ancient sedimentary rock and the like.
The recent flypast of Pluto / Charon gave us dramatic new geology with flowing water / methane ice, and changing, active landscapes.
The next focus for New horizons will be a Kuiper Belt object , 2014 MU69, about a billion miles beyond Pluto.

As we speak, tests are being run for Orion, NASAs next big thing, which will launch into lower Earth - orbit on December 4th as a test prelude to manned deep space missions, ultimately using a module which will facilitate deep space missions, but hasn't been created yet !
I'm a little dubious, given that the new Orion craft will be capable of  twenty- one days in space - surely not long enough to go anywhere meaningful - or is there some as yet unexplained quantum secret ?
As well as this, rather strangely, objects to be carried include a rubber duck, and a giant cookie - I kid you not !
So the next 'big' proposal from NASA involves astronauts circumnavigating the moon with the munchies and toys...

Surely the widespread legalisation of pot in the U.S.A. has affected hitherto serious decisions ?
Good to know then, that in this new space race, priorities are suitably warped...
