Excellent!  I've always been somewhat skeptical of dark matter.  It just seemed like too much of a fudge to preserve some pretty math.

He's already won the Danish (IIRC) version for this work, and well...if this goes through and gets enough verification can you imagine the blood in the halls of physics labs?  Not to mention what this could do to grants everywhere.

Then again, aether was a scientific bet for well over a century IIRC...

Animation of Occator Crater on Ceres:

http://www.dlr.de/dlr/en/Portaldata/1/Resources/videos/2016/Dawn_Ceres_Occator_600.mp4

It's the crater with the white spots. Video was created by taking 548 images shot by the framing camera onboard Dawn and plugging them into a analysis model that produced 106 million distinct surface points for a 3D terrain model.

The white stuff are the famous white spots seen on initial approach, by now found to likely by calcerous salt. There are by now various theories on how those came to be there, mostly in that the impact that formed the crater either evaporated ice leaving salt and mud or the energy of the impact hydrodynamically changing crustal material to produce salt.

Researchers from the University of Amsterdam's (UvA) GRAPPA Center of Excellence have just published the most precise analysis of the fluctuations in the gamma-ray background to date. By making use of more than six years of data gathered by the Fermi Large Area Telescope, the researchers found two different source classes contributing to the gamma-ray background. No traces of a contribution of dark matter particles were found in the analysis.

...

To date, the Fermi telescope has not detected any conclusive indication of gamma-ray emission originating from dark-matter particles. Also, this latest study showed no indication of a signal associated with dark matter. Using their data, Fornasa and colleagues were even able to rule out some models of dark matter that would have produced a detectable signal.

Read more at: http://phys.org/news/2016-12-dark-gamma-ray-background.html

Emphasis above, mine.  They've gotten to the point where they're outright killing theoretical models, which...is going to put a pinch on the theory.  Makes me wonder if it might be a point in favor of Verlinde's gravity theory.

Flight over Mawrth Valley, Mars.

http://www.dlr.de/dlr/en/Portaldata/1/Resources/videos/2016/794-MawrthVallis-movie-ArsSonor_600.mp4

Generated similarly to the above Occator Crater video, using HRSC images from Mars Express for overlay of the terrain model. The overflight begins in the North where Mawrth exits into the lowlands about where Chrysae Planitia and Utopia Planitia meet; the crater flown towards at the end should be Rutherford (or possibly Trouvelot).

HRSC takes real color imagery. The white deposits in this case are clay minerals while the black deposits are volcanic ash.

The name of the valley might be recognized by some from the Martian movie. A considerable portion of it was set there.

Clearly we need to research this phenomenon. We'll need a research grant in order to obtain a bucket of dark matter. We'll perform experiments to see how many and how large research grants we can generate with that bucket. As a control group, we'll also have an empty bucket, and see how many grants we can get by just telling folks we want to see if there's any dark matter inside.

It's official, Pluto became edgy and gothy names!

Chutho a thing now on Pluto! So is the other names used by the New Horizon team when it first arrived.



Take that Disney themed Pluto, Chutho is in charge!

Interesting Development with the Rosetta Team who's little probe had been orbiting Comet 67P/Churyumov–Gerasimenko. The Team apparently caught on imaging a cliff side collapsing.  This revealed some  of the interior of the Comet that hadn't been seen before.

Looks like new Administration has jumped started NASA into planning something.

Space.com has reported NASA has plans to established a Luna Station in orbit of the Moon in order gain more experience handling deep exploration.  Also the small space station is to sever as a jump point for robotic missions going to the surface of the Moon and other efforts. 

Is this good step?  They still need learn how to control radiation exposure from the sun for the longer trips.
Will ISS be able be sustained?

The SLS apparently going to be powering much of the missions.  I do wonder why no serious efforts were made try go explore while Obama Administration was around.  (I'm not trying get political here.)

Didn't Obama try to call for manned expeditions to asteroids?  Both as practice for longer range missions and practice for resource exploitation.

Realistically, a manned lunar station is a better bet than going straight to the asteroids. We don't really have that much experience outside Earth's magnetosphere; ISS is too low.

Plus lunar station managing lunar probes maps to Phobos landing managing Martian probes, which is a great precursor to getting back-hoes to Mars.

(Personal obsession. I've been predicting sub-soil ice since the 1980s, and almost every mystery about Mars can be answered by getting some people there with a back-hoe.)

Putting a base on the Moon would be a logical step before putting one on Mars.
It is closer, and thus cheaper and safer. However it would require some digging to give the base some extra protection.
