Colonization of Ceres by a Breakaway Civilization?

Here is a very interesting post by Paul LaViolette.

Dwarf planet Ceres

When NASA’s Dawn ion propulsion spacecraft approached Ceres and began relaying back photos clearer than any seen to date, astronomers were surprised to find two bright spots within a crater on its surface.  The suggested explanation is that these spots are either surface ice or a whitish salt deposit.  So they are anxious to have a closer look when Ceres makes its close encounter in a few weeks and begins taking close up photos of its surface.

Here are some media links about this:

• Video showing the planet rotating:

I don’t buy the given explanations for several reasons.

• First, the spots are brighter than the illumination of the day side.  Ice or salt would not do this.  This might be possible in the above photo if there were surfaces oriented at 45° angle to the Sun reflecting sunlight toward the spacecraft.  But look at the next photo below.  The spots stay illuminated even at sunset.  If it were ice, sunlight should be reflecting at low angle from the surface; not toward the spacecraft.  Now look at the photo below that where Ceres has rotated a bit more.  The spots are at the terminator shadow and still illuminated.  Now check out the image below that.  The spots are now on the night side of the terminator and we still see them illuminated.  They are not as bright as in the first photo because now we are seeing them at a low angle.  Light reflecting off of ice or salt does not do this.
