Unlocking its secrets with lasers. Sure would be nice if we could figure out how to a) manufacture in quantity and b) use it for propulsion.

Swiss Space Systems
They’ve gone belly up, but this is bizarre:
The news comes at the end of a difficult year for S3.
In August its founder and CEO, Pascal Jaussi, was left seriously injured after being beaten up and set on fire by two attackers in a forest.
The media reported at the time that Jaussi was forced to drive his car into a forest, where he was doused in petrol and set on fire. He managed to get himself out of the vehicle and call a friend, who alerted emergency services.
The investigation is ongoing.
The space business can be dangerous, but I’d sure like to know the back story here.
Densifying Hydrogen
The irony I find here is that this technology will be more useful in space than for a first stage, which wants higher-density fuel. And with low-boiloff propellant depots in orbit, the case for SLS looks even weaker.
Rogue One
…makes white guys the enemy of the future. Of course, it’s coming from people who think they’re the enemy of the past and present. But Christian Toto liked it.
I haven’t seen it yet.
[Sunday-morning update]
I’ve never been a huge Star Wars fan. It’s not really SF, or at least not hard SF. The effects were great for their time, but for my generation, 2001 is the touchstone.
Make NASA Great Again
My thoughts on the passing of John Glenn, over at National Review.

Buzz Aldrin remembers his former colleague.

Dear President Trump, here’s how to make space great:
This list of goals sounds audacious, perhaps outrageous, but it is entirely within the capability and character of the people who built the Transcontinental Railroad, the Hoover Dam, and conquered a continent. Americans are leaders in every one of these fields. It is only necessary for the new President to unleash America’s potential—once unleashed, American innovators will move these dreams toward reality faster than anyone can imagine.
Asteroid mining, moon mining, propellant depots, solar-power satellites, asteroid deflection? Crazy talk, when instead we could be building a giant rocket.
I had dinner with Coyote in Seattle last June.

Bill Gates’s and America’s false memory of Apollo:
So whether you agree with Bill Gates and his assessment of Trump or not, it’s important to remember that funding for the Apollo program was opposed by the majority of Americans. Why then does America have this bizarre memory of the program? You can blame the baby boomers like Gates.
The baby boomers were kids during the Apollo space program. And when you’re a kid you don’t have much to worry about in the way of paying the bills or public policy. You certainly don’t have fully formed political ideas about, say, ways that government funds can be better used than blasting people into space.
But that was precisely what happened. Baby boomers, as children of the 1960s, just remember the speeches on TV and watching the moon landing. They don’t remember that the majority of Americans (American adults, as those are the people who get polled) thought that the Apollo space program was a waste of money.
Roger Launius, chief historian at NASA, put it best in a 2005 paper: “While there may be many myths about Apollo and spaceflight, the principal one is the story of a resolute nation moving outward into the unknown beyond Earth.”
This is why, as I wrote a few months ago:
Because they view Apollo as the model for how large space programs should operate, and because they believe that Apollo represented a moment of national unity, they seem to think that we ought to recreate it.
In a sense, however, a critical reason that we cannot do what they want is because we never really did it the first time.
Stop trying to make Apollo happen again.
The New Attorney General
This is bad news:
Mr. Sessions has heavily influenced the makeup of the transition team for the National Aeronautics and Space Administration, these people said, with many of those appointed favoring greater emphasis on manned exploration missions to the moon and deeper into the solar system.
Candidates for NASA administrator also are being vetted, in part, by Mr. Sessions or his associates, while officials at Boeing Co. and other legacy aerospace giants increasingly believe Mr. Sessions will help temper possible changes inside NASA that would hurt existing, big-ticket projects to ultimately send astronauts to Mars.
Not coincidentally, such exploration would rely heavily on scientists, workers and rocket technology based in Alabama, at NASA’s Marshall Space Flight Center in Huntsville. Mr. Sessions over the years has been a champion of the agency’s proposed heavy-lift rocket, dubbed Space Launch System, or SLS, and helped protect its roughly $2 billion-a-year price tag from cutbacks proposed by the Obama White House.
I like how Pasztor unironically talks about SLS/Orion as part of sending “astronauts to Mars,” when they’re almost completely irrelevant to it. This pork-mongering is part of the tragedy of Apollo.
This is the first time I’ve seen Doug Cooke’s name as a potential NASA administrator. He’d be as bad as, or worse than, a second stint by Mike Griffin.
[Update a while later]
Yes, Trump should focus on the government, not Boeing or Lockmart. They’re just doing what they’re incented to do.
And he should take a look at SLS.
No Guts, No Glory
NASA wants to see SpaceX do a test landing on Mars before they’ll commit any instruments to it.
Meanwhile, in addition to delaying return to flight into January, they’ve now officially slipped first crew Dragon launch into 2018. Not really surprising, given the recent setback.
Bootstrapping The Solar System
Advances in robotics and additive manufacturing have become game-changing for the prospects of space industry. It has become feasible to bootstrap a self-sustaining, self-expanding industry at reasonably low cost. Simple modeling was developed to identify the main parameters of successful bootstrapping. This indicates that bootstrapping can be achieved with as little as 12 metric tons (MT) landed on the Moon during a period of about 20 years. The equipment will be teleoperated and then transitioned to full autonomy so the industry can spread to the asteroid belt and beyond. The strategy begins with a sub-replicating system and evolves it toward full self-sustainability (full closure) via an in situ technology spiral. The industry grows exponentially due to the free real estate, energy, and material resources of space. The mass of industrial assets at the end of bootstrapping will be 156 MT with 60 humanoid robots, or as high as 40,000 MT with as many as 100,000 humanoid robots if faster manufacturing is supported by launching a total of 41 MT to the Moon. Within another few decades with no further investment, it can have millions of times the industrial capacity of the United States. Modeling over wide parameter ranges indicates this is reasonable, but further analysis is needed. This industry promises to revolutionize the human condition.
Looks interesting. I remember talks like this at the Princeton conferences 35 years ago. It’s technology is finally starting to evolve to allow it to happen.

Sorry for missing link on Carlos’s piece, fixed now.
“Space Exploration”
A list of reasons we do it that have nothing to do with, you know, space. It gets back to my theme that “exploration” is not an end in itself; it’s a means. But we have to decide what we’re trying to accomplish, and kumbaya isn’t sufficient.
The First Americans
How did they get here? Apparently not across the Bering land bridge.
It’s interesting to see how much “science” has been overturned since I was kid, about things like dinosaurs, space and human migration. I suspect that the same will occur in nutrition and climate.
