A (sort of) debate between Paul Spudis and John Grunsfeld. I think that Grunsfeld is far too pessimistic about the moon, but I also think that this debate is irrelevant. Our future in space will be determined by billionaires, not Congress or NASA.

A Useful Experiment
I’ve been watching this Kickstarter project. I was talking to Jon Morse a couple weeks ago, and he didn’t expect it to succeed. He was right; it only raised a third of the million dollars it sought. But it’s a useful market test for private space exploration. Maybe if they shoot for half that. I do think we’re entering a new era of what I call “normal science,” before the Manhattan Project, the Cold War, and Apollo screwed everything up, and things like the big telescopes (the first high-tech astronomy programs) were funded philanthropically.
Satellite Servicing
NASA and DARPA are starting to get serious about it. I’ll probably try to join the consortium, for some business plans I have.
Thiel Versus Sessions
They’re battling over the future of NASA.
Thiel is pushing for a 21st-century space policy. Sessions represents the past, Apolloism, space socialism, and pork. He should stick to being AG.

@Rand_Simberg Yes. THE "A" in #MAGA does not stand for Alabama.

Not sure what “commercial space trade association” Tim Fernholz thinks that Alan Stern leads.

Tim pointed out to me that he’s chairman of the board of CSF, which I hadn’t known, or had forgotten. But I pointed out to him that Eric Stallmer is really the person who “leads” it, which he agreed was fair.
More on this topic from Eric Berger.
[Update a while later]
Not exactly space related, but sort of, in the sense that indefinite lifespan will help with opening the universe, an interesting description of what else Thiel is up to.

Speaking of the moon, Paul Spudis has some ideas about how to make space great again. I actually agree with most of it, except for this:
The Orion spacecraft and its SLS launch vehicle are currently in final stages of development, with initial test flights planned for 2018. We can use these existing systems to return to the Moon; indeed, as the remnants of the cancelled Constellation program, they are already optimized for cislunar missions. The only missing piece is a lander to put people on to the lunar surface. NASA’s Altair lander program was cancelled in 2011, but fortunately, a lander may be ready very soon. The United Launch Alliance has outlined a plan for a human-rated lander based around the venerable Centaur stage, using modified RL-10 engines. This vehicle is almost perfectly configured to return people to the Moon, as it is intended to be reusable and utilizes the LOX-hydrogen propellant that we will produce on the lunar surface.
The surest way to ensure that this doesn’t happen is to plan it around SLS/Orion, which will fly so rarely that we will make very little progress. He’s postulating the existence of a ULA lander, while ignoring the firmer plans for Vulcan ACES, which would be the natural way to carry out these mission (Orion might be usable in that scenario, but not SLS, and Dragon would probably be more cost effective). And as usual over there, the comments, particularly from “Bilgamesh,” are idiotic. And even more particularly the fantasy about flying SLS a dozen times a year.
Anti-Matter
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.
