My guess is ice below the surface revealed by an impact.

The one on the right with lighted corners is oddly symetrical.

There is more to worry about in space than dust, rocks, and radiation ...

Ice or fresh debris gouged out from a comet or meteor.

Does anyone know how big an area that is?I can confidently say the answer is "yes".
As for us, it says 700m per pixel, so you could guess the pixel width, or go to the Dawn site and get the true resolution. I'm gonna say "tens of kilometers wide" for the big one.

That spy satellite only had 22000 miles to travel, 22000 miles to transmit data back, and only had a couple of years to live.
Dawn has to travel hundreds of millions of miles, has multiple destinations to go to and orbit, and has to transmit its findings up to ~360 million miles back to earth.
Furthermore the imaging systems on Dawn need to take care of multiple roles. Spy satellites have but one job: image minute detail from just one focal distance: 22000 miles.
Rocket science ain’t easy
To: sten
4500 miles and a resolution of 700m per pixel?! spy satellites from the early 70s could take pictures from 22,000 miles and had a resolution of < 1m per pixel. ONE METER. 40 year old tech was 490,000x (700x700) better?! You don't actually think they're showing us what NASA has to work with, do you? I have a leaked photo of one of the REAL Ceres photos here - just a tad better than what they let US see...

Those are some tough-looking spots. I hope we sent the ultra-concentrated Dawn!
Ice.

Current position. Its only made one close pass about 8000 miles away from the surface. Yer way out of date. That was the initial pass back in March or so. Right now, as of May 26, 2015 02:03:09 UTC, it's at an altitude of 3750 miles, with rockets on!

Actually no I’m not out of date. The NASA data is current.
Science writers are morons.

Dude, its on the dark side just over 40,000 miles out. My data is from NASA and is in real time whether you like it or not.
