NASA to Spend US$2,941,394,557 on SpaceX’s Lunar Starship

If I were inclined toward a cynical, Stygian, and conspiratorial outlook instead of my customary sunny and optimistic disposition, I might interpret this news as follows.

Look, NASA doesn't really want to land on the Moon. If they did, they'd have been working on, you know, landing on the Moon, instead of spending billions on a Lunar Tollbooth which will complicate any missions to the surface but spread that delectable taxpayer (and borrowed, and freshly-printed) money around to the congressional districts and states of the politicians who fund the agency. As Robert Zubrin has observed, “NASA used to spend money to fly missions. Now they fly missions to spend money.” If those pesky politicians should demand they actually land on the Moon, which might get the juices up among the hoi polloi and motivate demands for NASA to actually expand the human presence beyond Earth as opposed to flushing money down the toilet on the Space Launch System (SLS) and other grotesque extravagances, then why not choose the cheapest alternative, one with (under the NASA view of things) the highest technological risk and then, when it inevitably fails, say “We told you so. Now, can we return to our incremental plan for flags and footprints sometime around 2030, or 2040, or, well…when we're ready? And how about a budget bump in the next fiscal year?”

Further, in choosing the SpaceX Starship, they not only get the NASA camel's nose under the SpaceX frenetic incremental refinement development tent, they, by spending less than what they're wasting every year on SLS, its ground support equipment, and Orion (the “deep space exploration vehicle” without a toilet), get the whole NASA camel into the heart of Starship development, sending “hither swarms of Officers to harrass our people, and eat out their substance”, bury it in paperwork, cripple it by hordes of inspectors, sub-sub administrators for diversity, and all of the other reasons no human has ventured beyond low Earth orbit since 1972.

But this may all backfire on NASA, and that would be just wonderful. If there's one thing we've learned over the years, it's not to bet against SpaceX. (Eric Berger's wonderful book, Liftoff, which chronicles the start-up and hard-scrabble years developing and debugging the Falcon 1, is an excellent look into the driven SpaceX culture.) What if SpaceX takes the three billion, nods to the NASA minions, continues their frenetic development pace, and succeeds? A functioning Super Heavy, reusable tankers, and lunar Starship, all of which are required to deliver on the NASA contract, will render SLS, Orion, Gateway/GLOP/whatever they're calling it, impotent and obsolete, and be able to deliver tens of tonnes of cargo and dozens of paying passengers to the Moon on a monthly schedule, while NASA is still pursuing its plans to send four civil service space cadets on brief excursions “every year or two” at a billion or so a pop.

Well, at least when they get there, they'll be able to stay at Bigelow’s lunar hotel, which will have toilets, even in the economy rooms affordable on NASA per diem.

Robin Hanson—Explaining Stylized UFO Facts: Panspermia Siblings, World Government, Moral Ideology, and Complexity Rot

Might millions of years of woke ideology, ever-increasing sclerotic regulation, and pervasive incompetence due to lack of competition explain the seemingly irrational behaviour of aliens responsible for the UFO phenomenon? Also see the earlier post, “UFO Stylized Social Facts”.

I continue to think they're dumber still: “Flying Saucers Explained”.

Age of Stupid—Academic Journals Are Omitting the Titles of Cited Papers

This makes citations almost worthless unless you want to look up every one to see what it's about. The “saving paper” argument is absurd in an age where the vast majority of publication is electronic and actual printed journals go for exorbitant prices. You almost wonder if academics don't want you to check the cited papers.

The Bitcoin Blockchain: A Secure, Worldwide, and Unjammable “Numbers Station”?

Here is more about numbers stations. Of course, you'll want to encrypt any message you embed in a blockchain transaction with, for example, my JavaScrypt.

It appears everybody hasn't yet gotten the message. Here is a numbers station broadcasting in Russian, recorded earlier today (2021-04-05) in Finland.

Estimating the Probability We Are Living in a Computer Simulation


It is shown that under reasonable assumptions a Drake-style equation can be obtained for the probability that our universe is the result of a deliberate simulation. Evaluating loose bounds for certain terms in the equation shows that the probability is unlikely to be as high as previously reported in the literature, especially in a scenario where the simulations are recursive. Furthermore, we investigate the possibility of eavesdropping from the outside of such a simulation and introduce a general attack that can circumvent attempts at using quantum cryptography inside the simulation, even if the quantum properties of the simulation are genuine.

The authors do note, however, that one potential solution to the Fermi paradox might be that we are in a simulation and the absence of aliens is due to the simulators using a variable level of complexity to reduce the computing power required. If the simulation is confined to Earth, there would be no reason to include intelligent aliens from other planets. Here is a PDF version of the paper.

The Book Even Theodore Dalrymple Couldn't Finish

Here is the book, The Ahuman Manifesto: Activism for the End of the Anthropocene. A brief quote from the volume:

The negative value of the end of anthropocentrism is where the jubilance of the world begins. The everything else that comes at the end of these systems is primarily only really the end of the primacy of one isomorphic functioning mode of knowledge. Difference and proliferation which seethes beneath in a germinal state has the capacity to express when the anthropocentric mode is diminished to one of many ways, historical or majoritarian-hysterical.

The Kindle edition sells for US$ 26.95.
