OK, so how soon could this be available for a planetary mission? What’s the power/mass ratio, and cost, compared to an RTG?

Orbital ATK
This is interesting. The company is getting into the orbital assembly business:
Phase one of CIRAS began in September 2016 and will last a total of two years. During this period, Orbital ATK will lead the team in maturing technologies necessary for robotic assembly of large space structures, such as next-generation telescopes or solar-powered structures for transport or communications. These capabilities include methods to connect or disconnect joints on a structure and address precision measuring and alignment through a 15-meter robotic arm and a precision robot. The team will also develop the technology needed to conduct in-orbit modular assembly of structures, allowing parts to be brought to space as needed via multiple launches, which simplifies the design of spacecraft and reduces cost. [Emphasis mine]
They must realize that this increases the risk to SLS, and their SRB production. Have they decided that this new business focus is a better bet?
A Good Space “First”
Thanks to SpaceX and ULA, the US is set to outlaunch Russia this year, for the first time ever.
Meanwhile, in Huntsville, NASA is trying to figure out just how low a flight rate they can get to.

Unsurprisingly, the Coalition for Deep Space Exploration’s “roadmap” includes the dead ends of SLS and Orion.
The Recount Circus
It should effectively be over, because Michigan has certified for Trump. Even if Wisconsin hadn’t rejected the request for a hand recount, and Pennsylvania would allow one, Trump would still (absent faithless electors) have a majority of the Electoral College which (I don’t know why the ignorant continue to whine about the popular vote — Oh, wait, yes I do) is how we elect presidents in the United STATES of America. But it will continue, because it has nothing to do with the “integrity of the vote,” and everything to do with Green Party fundraising, and continuing chaos.
The Uncanny Valley
…still has yet to be traversed.
Statins
“No scientific evidence for their use.”
It’s not just nutrition that’s a scientific Charlie Foxtrot. I had a cardiologist in Florida try to put me on Lipitor a few years ago. I told her, “there’s no scientific evidence that it reduces heart risk in people like me,” I told her. “Where did you hear that?” she demanded. “The Pfizer web site,” I replied. She was flabbergasted.
Elon Musk And “Space Exploration”
Here‘s kind of a typically dumb piece, which reeks of Apolloism:
I am a big fan of space exploration and I think that Elon Musk’s SpaceX is a visionary company that is trying to conduct meaningful space exploration. Yet, Congress might want to take a hard look at the ticket price for Musk’s latest endeavor before spending $10 billion to populate Mars.
First, SpaceX is not “trying to conduct meaningful space exploration.” It is trying to establish human settlements on Mars. And if it could really be done for as little as $10B, that would be an incredible bargain to the taxpayer, compared to (say) spending that same amount on SLS/Orion in the next three years, as NASA currently proposes.
I am a limited government conservative, yet I fully support government funded space travel. But it must be smart and it can’t fund risky adventures. The one concern I have about SpaceX’s plan to travel to Mars is that, on its face, the plan seems more like a for-profit enterprise than true space exploration. I would support pure exploration of Mars and a project that has a stated goal of forwarding humanity. Musk’s idea seems like he is more in it for profit than science.
#ProTip: “Limited-government conservatives” do not spurn profit. And even if making a profit on “science” was really a bad thing, settling Mars has nothing to do with “science.”
According to the Los Angeles Times, Musk has received about $4.9 billion already in government subsidies for his three companies. Now he comes to the federal government wanting more. And he has been the beneficiary of many contracts to put satellites into space that run in the billions.
#ProTip: Tesla and Solar City get subsidies. SpaceX gets contracts. One is nothing like the other two, other than federal dollars are involved.
This is a laudable idea and Elon Musk should be celebrated as one of the great innovators of our time, yet the taxpayers should not be funding for profit space exploration and may want to find another contractor who wants to go to space for purely scientific space exploration.
This is a perfect example of the mental confusion that occurs when (as many ignorantly did with Apollo) we conflate “exploration” with “science” with space development and settlement. Mr. Woodson needs to go read my recent screed.

As usual, the comments over there are idiotic, including a couple appearances of the ignorant “NASA’s Muslim outreach.”
Starship Troopers
…is the new Art of War.
And in that vein, it’s worth noting all the amusing butthurt among moron fans of the original Verhoeven dreck at the news that someone is going to do it right.

Speaking of classic science fiction, an ode to Harlan Ellison, who is still with us.
And from occasional commenter Laura Montgomery, “How John Varley Broke My Heart But Other Science Fiction Writers Shouldn’t Have To“: some thoughts on space regulations.

Link to Laura Montgomery’s blog was broken. Fixed now. Sorry!

The GAO has issued a new report. I haven’t read it yet.

Are we on the verge of a cure? That would be nice.
