Oblique view of Ceres’s bright spots

Occator Crater on Ceres

Cool image time! The image above is a newly released image of Occator Crater on Ceres, the location of the dwarf planet’s double bright spots, taken by Dawn in October.

I have cropped the image to focus on the crater and the bright spots. Unlike most previous images, this one is taken from an angle to bring out the topography, which also confirms what other data had shown, that the bright spots are not on top of any peaks. If anything, they appear to be located at low spots in the crater, as that previous data had suggested.

Though the spots are not really very bright, they are very bright relative to the dark surface of Ceres. This is why it is difficult to get a good image of them. Either you have to over-expose the spots to see the surface details around them, or under-expose the surface around them to see some detail in the spots. This image tries to find a middle ground.

Eventually they will move Dawn in very close to try to get higher resolution images of the spots alone. At that time we might finally be able to get a better understanding of what causes them.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Available everywhere for $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from the ebook publisher, ebookit. And if you buy it from ebookit you don't support the big tech companies and I get a bigger cut much sooner.
