As the Renaissance breathes new life into Europe, Copernicus develops mathematical proofs for the sun resting in the center of the universe. And from his works, a new world is born. The scientific world gets faster and faster. Revolutions of all kinds begin to set off chains of events that reshape human history. And as science improves, so do the tools of war. Both will be necessary to propel humanity to the stars. Join us on this race through the scientific works between the Renaissance and the Industrial Revolution.
Copernicus’ publishing really came down to the wire! Legend has it that he was given the final printed pages on his death bed. When they presented him with the book, he awoke from a coma, saw his life’s work and finally passed away in peace. Or so the story goes.

What do Ptolemy and ancient Chinese rockets have in common? Without either of these things, space flight wouldn’t be possible! In order to understand how we started traveling amongst the stars, we have to talk about how we started studying stars in the first place. Since the very first civilizations we’ve always looked at the night sky with wonder & curiosity but also as a way to try and understand the future and time itself.

Gene Roddenberry was his own worst enemy
Ed Driscoll reviews the first of three volumes by Marc Cushman, relating the story behind the legendary original Star Trek TV series. Much of the first volume is apparently about the problems of getting NBC to let Gene Roddenberry back into their good graces after he humiliated the network over an earlier TV show:
Gene Roddenberry (1921-1991) was a religious agnostic and left-leaning Texan who became a WWII Army Air Force B-17 pilot, then an LA policeman who wrote numerous scripts for the burgeoning television industry in the 1950s. Eventually, he graduated to producing his own TV show in 1963, The Lieutenant, purchased by NBC and built around Gary Lockwood, the future guest star of Star Trek‘s second pilot, and the co-star of another landmark 1960s science fiction achievement, Stanley Kubrick’s 2001: A Space Odyssey.
The Lieutenant was for the most part a formulaic “military procedural” about life at Camp Pendleton, and featured numerous future Star Trek guest stars and cast members. However, Roddenberry, as was his wont, eventually decided to push the envelope, and put into production an episode on racism in the Marines called “To Set It Right,” with guest stars Dennis Hopper, future Star Trek regular Nichelle Nichols and future Trek guest star Don Marshall. The episode lost the support of the Marines, and the good will of NBC. As Roddenberry later recounted, “My problem was not the Marine Corps; it was NBC, who turned down the show flat … There was only one thing I could do, I went to the NAACP and they lowered the boom on NBC.”
As Cushman writes, this did not endear himself with NBC’s executive suit. “Roddenberry had won the battle … but lost the war. Despite satisfactory ratings, The Lieutenant was cancelled.” And NBC’s executives would not forget being hung out to dry by one of their product suppliers.
Even before The Lieutenant‘s only season of production was complete, Roddenberry began crafting a television show he called Star Trek. He had somehow stumbled into the perfect format for an hour-long network television series. While he admired shows such as Rod Serling’s The Twilight Zone and its recombinant network rival The Outer Limits for their ability to comment on American society through the metaphors of science fiction and horror, these were anthology shows, introducing a new cast each week. He knew the most successful network series were those with a recurring cast, such the many westerns that aired during the 1950s and ’60s, such as the long-running Bonanza and Gunsmoke. Viewers treated these archetypal characters almost as their own family members, which in turn encouraged them to tune in each week.
Given the networks’ love of westerns in the 1960s, it’s no coincidence that Roddenberry’s first pitch to the networks used the phrase “Wagon Train to the stars” as a metaphor to describe the show. (As Cushman writes, veteran western and science fiction writer Samuel Peeples actually coined that phrase, the first of many bits of Star Trek lore that Roddenberry would eventually co-opt and take credit for.)
It’s also no coincidence that the show’s second in command was written by Roddenberry as “a mysterious female, slim and dark, expressionless, cool, one of those women who will always look the same between years 20 and 50.” As Cushman deadpans, “To be more specific: actress Majel Barrett, Roddenberry’s lover.” (Roddenberry was also having a tryst with Nichelle Nichols; she would find her way into Star Trek‘s regular cast as well.) While the pointed-eared alien Mr. Spock was also present, he was much more in the background in Roddenberry’s first draft of Star Trek.

“… what’s happening now is even better than Apollo”
At Popular Mechanics, Joe Pappalardo reminds us that the 50th anniversary of the Apollo 11 lunar landing is coming up next month, but that current developments in space are worth celebrating too:
Apollo was born of Cold War desperation: a political exercise that paid enormous scientific and technological dividends. After the launch of Sputnik in 1957, it became vital to beat the Soviet Union to the Moon, a geopolitical urge that created an enormous budgetary effort.
The problem with politically motivated — well, anything — is that the faucet of support can be closed just as quickly as it opened. It happened to Apollo, as follow on missions were cancelled and the focus shifted to a reusable craft to service low-earth orbit. This pattern of shifting space priorities and strategies whipsawed NASA, most noticeably when the Obama administration’s cancellation of the Bush-era Constellation moon program in 2010.
But multiple private companies pursuing their niches in space have an obvious redundancy. While companies may rise and fall, the very nature of a commercial effort isn’t as dependent on government funding. If it’s worth doing, especially if it makes money, space industry will endure political shifts. The objectives of a well-run company do not change that much every four years.
That leaves today’s NASA with a choice: Do it themselves and control everything (the traditional way), or fund private companies to develop the tech the agency needs and then allow them to sell their services to any nation, company, or individual (the new way). With those services on the open market, NASA would be one of many customers for a new U.S.-based space economy.
This debate is boiling over right now. The ongoing effort to return to the moon, called Artemis (after Apollo’s sister), is becoming a lesson in the advantages of the commercial model.
[…]
If only investment guaranteed results. For those who miss bloated, government-run spaceflight, there is already a NASA spacecraft mired in the old ways of thinking. The feds have sunk a lot of money into the Space Launch System, a mega-rocket built to NASA specs for deep space missions. It was supposed to fly in 2017, but we’ll be lucky to see a first flight in 2020 — and it busted the $9.7 billion estimated budget, now costing about $12 billion.
But something happened during these SLS delays: the commercial space industry started delivering on its promises. Most visibly, private firms have been delivering supplies to the International Space Station for years and (hopefully soon) will ferry astronauts as well. Blue Origin and SpaceX has started development of crewed spacecraft able to reach to the moon and Mars. Elon Musk even sold a moon trip to a Japanese billionaire.

The real explanation for our lack of moonbases/Concorde 2’s/great walls/pyramids
Homoitalicus Blog responds to a new book [At Our Wit’s End by Edward Dutton and Michael Woodley of Menie] that concludes that we (western civilization) are headed toward a similar fate as the western Roman Empire:
The reason that these staggering feats of engineering haven’t been repeated is more to do with economics and politics than with any perceived lack of engineering Genius in the population. The authors fail to reflect that emerging from the massively centralised wartime economy of the West there was an enormous technological infrastructure of scientists and capable administrators just sat there with no more Nazis to fight, communist megalomaniacs to support, Atom bombs to build and test, or greatest seabourne invasions in history to plan and implement.
This was probably the greatest concentration of intellect ever harnessed to a single cause and hopefully we’ll never need to see its like again
With the war done and dusted some new purpose needed to be found for all this talent, the way of government being what it is, returning all these geniuses to normal boring peacetime activity was never an option.
Newly nationalised aircraft industries took the wartime inventions of jet engine and the rest and evolved them with massive amounts of financial input from the government into Concorde, truly a magnificent aircraft but one which could uncharitably be described as using taxpayers’ money to ferry plutocrats from one side of the Atlantic to the other. Whether it ever really paid for itself is a moot point and the unseemly haste with which it was dumped after the crash tends to imply that its 50-year-old airframes were becoming a burden, and the economic case for making a new generation of supersonic planes is weak – luckily the will in the west for another taxpayer-funded effort doesn’t seem to be there. That is progress.
Likewise the man on the moon, possible only because of the Cold War space race.
The authors might as well explain the fact that we haven’t build another pyramid of Giza or Great Wall of China.
Their assertion that a general decline in the amount of creativity (which is correlated strongly with g) is justified by the observable decline in the quality of the output of the BBC. However other possible reasons for this are the infestation of Cultural Marxism and its baleful handmaid, Political Correctness, which really mitigate against creative thought. It is impossible to imagine making The Life of Brian, or The Sweeney or countless other shows which we enjoyed in our youth nowadays largely for reasons of PC and the fact that the BBC’s mission is now brainwashing rather than entertainment. State broadcasters the world over will suffer from the same problem, as does (worryingly) the world of academe in which speakers of truth or opinion which lie outwith accepted and very tightly bounded acceptability, are routinely no-platformed or summarily sacked. The teaching of history and the humanities generally has been debased, and only the STEM subjects seem to have resisted (excluding the question of Climate Change which has taken on the trappings of a religion rather than serious science).
As a consequence it is impossible to separate the effects of CM from the mooted results of a generalised decline in intelligence, and the authors are wrong not to point this out.
They don’t consider either the likely effect of the 20th century’s great blood letting in the fields of Flanders. A substantial proportion of the best and brightest of a generation were ground into the mud there before being able to procreate. I would be surprised if that had no effect on the quality of the gene pool.

NASA to export bullying off the Earth to small, harmless objects in the solar system
Colby Cosh on NASA’s latest plan for “nudging” an asteroid out of its orbit:
NASA has a plan — a serious plan, which it intends to carry out pretty soon — to smash a spacecraft into an object in the solar system and intentionally change its orbit. I confess I don’t quite know why this act of awesome American techno-hubris hasn’t been bigger news. I think partly it is because the mission comes under the heading of “planetary defence” against small natural objects straying into the path of the Earth. Science reporters on that beat are easily distracted by apocalyptic fantasies, and by smirking anthropology about the actually-quite-numerous band of researchers trying to deal with this arguably-quite-important subject.
Part of the problem may be that NASA’s mission to mess with the asteroid Didymos B is hidden under a mountain of technical jargon about “kinetic impactors” and “xenon thrusters.” And part of it is surely the hard-earned professional knowledge that NASA ends up implementing about one plan for every 10 it makes. Accountants have a way of showing up with an axe at the last minute.
Still, the idea is pretty neat, and not just because it appeals to everyone’s natural appetite for destruction. The basic premise of the DART (Double Asteroid Redirection Test) is that our planet may one day face the asteroid/meteor/comet collision scenario outlined in a vast corpus of books and movies (Lucifer’s Hammer, Armageddon, Deep Impact). If that day comes, we as a species don’t want to just be winging it — so let’s go out now, find some innocent chunk of rock that isn’t bothering anybody, and see if we already have the technological capability to change its course.
This turns out not to necessarily involve Bruce Willis or Robert Duvall; mostly we just need Isaac Newton. The scheme of planetary defence now emerging from decades of speculation and effort emphasizes systematic tracking of near-Earth objects and early detection of potentially dangerous ones. If we can spot an approaching impactor soon enough, we don’t need to deliver a bundle of explosives: we can just nudge it out of the way.
Humanity has been pretty lucky that the asteroid impacts have been relatively rare since we started keeping track of important things like the planting calendar, the seasonal flooding of the rivers, and the ever-important (to the rulers) tax records. It wouldn’t take a particularly large object hurtling into the atmosphere at interplanetary speeds to ruin our collective day (year, decade, century, etc.). We think we know how to divert incoming dangerous objects … but we need to actually do it successfully before it becomes the last headline of all recorded history.

So.
The original line was, “If they give you ruled paper, write the other way.” As far as I can tell it’s Juan Ramón Jiménez’s.I am also now painfully aware I’ve written a half as ‘2/1’. Sorry maths.
Please note that this wasn’t intended to be a diatribe against critics or experts. They obviously play an important role. It was more directed at the recreational cynicism one comes across in daily life from time to time, generally pointed at young artists. I have had the privilege to meet plenty of people 1000x more talented than me, who are simultaneously doubting their abilities because of some stupid comment made by an unpleasant teacher or jaded family member.
If you are that artist, I really just wanted to say: You’re in good company; the Greats doubted themselves too. Don’t let the bastards get you down and I hope you make all manner of interesting and fantastic things.

QotD: The universe
There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.
There is another theory which states that this has already happened.

Stross in conversation with Heinlein
Charles Stross explains why so many Baby Boomer SF writers fall so far short when they write in imitation of Robert Heinlein:
RAH was, for better or worse, one of the dominant figures of American SF between roughly 1945 and 1990 (he died in 1988 but the publishing pipeline drips very slowly). During his extended career (he first began publishing short fiction in the mid-1930s) he moved through a number of distinct phases. One that’s particularly notable is the period from 1946 onwards when, with Scribners, he began publishing what today would be categorized as middle-grade SF novels (but were then more specifically boys adventure stories or childrens fiction): books such as Rocket Ship Galileo, Space Cadet, Red Planet, and Have Space Suit, Will Travel. There were in all roughly a dozen of these books published from 1947 to 1958, and as critic John Clute notes, they included some of the very best juvenile SF ever written (certainly at that point), and were free of many of the flaws that affected Heinlein’s later works — they maintained a strong narrative drive, were relatively free from his tendency to lecture the reader (which could become overwhelming in his later adult novels), and were well-structured as stories.
But most importantly, these were the go-to reading matter for the baby boom generation, kids born from 1945 onwards. It used to be said, somewhat snidely, that “the golden age of SF is 12”; if you were an American boy (or girl) born in 1945 you’d have turned 12 in 1957, just in time to read Time for the Stars or Citizen of the Galaxy. And you might well have begun publishing your own SF novels in the mid-1970s — if your name was Spider Robinson, or John Varley, or Gregory Benford, for example.
Then a disturbing pattern begins to show up.
The pattern: a white male author, born in the Boomer generation (1945-1964), with some or all of the P7 traits (Pale Patriarchal Protestant Plutocratic Penis-People of Power) returns to the reading of their childhood and decides that what the Youth of Today need is more of the same. Only Famous Dead Guy is Dead and no longer around to write more of the good stuff. Whereupon they endeavour to copy Famous Dead Guy’s methods but pay rather less attention to Famous Dead Guy’s twisty mind-set. The result (and the cause of James’s sinking feeling) is frequently an unironic pastiche that propagandizes an inherently conservative perception of Heinlein’s value-set.
It should be noted that Charles Stross is politically left, so calling something “conservative” is intended to be understood as a pejorative connotation, not merely descriptive.
But here’s the thing: as often as not, when you pick up a Heinlein tribute novel by a male boomer author, you’re getting a classic example of the second artist effect.
Heinlein, when he wasn’t cranking out 50K word short tie-in novels for the Boy Scouts of America, was actually trying to write about topics for which he (as a straight white male Californian who grew up from 1907-1930) had no developed vocabulary because such things simply weren’t talked about in Polite Society. Unlike most of his peers, he at least tried to look outside the box he grew up in. (A naturist and member of the Free Love movement in the 1920s, he hung out with Thelemites back when they were beyond the pale, and was considered too politically subversive to be called up for active duty in the US Navy during WW2.) But when he tried to look too far outside his zone of enculturation, Heinlein often got things horribly wrong. Writing before second-wave feminism (never mind third- or fourth-), he ended up producing Podkayne of Mars. Trying to examine the systemic racism of mid-20th century US society without being plugged into the internal dialog of the civil rights movement resulted in the execrable Farnham’s Freehold. But at least he was trying to engage, unlike many of his contemporaries (the cohort of authors fostered by John W. Campbell, SF editor extraordinaire and all-around horrible bigot). And sometimes he nailed his targets: The Moon is a Harsh Mistress as an attack on colonialism, for example (alas, it has mostly been claimed by the libertarian right), Starship Troopers with its slyly embedded messages that racial integration is the future and women are allowed to be starship captains (think how subversive this was in the mid-to-late 1950s when he was writing it).
In contrast, Heinlein’s boomer fans rarely seemed to notice that Heinlein was all about the inadmissible thought experiment, so their homages frequently came out as flat whitebread 1950s adventure yarns with blunt edges and not even the remotest whiff of edgy introspection, of consideration of the possibility that in the future things might be different (even if Heinlein’s version of diversity ultimately faltered and fell short).

Books on the ISS
No, that’s not books about the International Space Station, but physical books on the ISS:
The astronauts on the International Space Station are obviously busy people, but even busy people need some time to relax and unwind. In addition to a well-stocked film library (particularly strong on movies with a space theme, including 2001: A Space Odyssey and Gravity), there are also plenty of books in their informal library.
Some are brought up by the astronauts – Susan Helms was allowed ten paperbacks and chose Gone With the Wind, Vanity Fair and War and Peace in her carryon. Others come with space tourists such as billionaire businessman Charles Simonyi, who brought Faust and Robert Heinlein’s The Moon is a Harsh Mistress.
Authors whose works appear several times in the list include Daniel J. Boorstin (3 books), Terry Brooks (5), Lois McMaster Bujold (11), John Le Carré (3), and David Weber (13).

QotD: When the “Right Stuff” becomes “old school”
Consider the popular conception of firefighters: brave, selfless, strong enough to haul an incapacitated person from a burning building.
A few years ago, at a conference, I learned that many women were failing to qualify as firefighters, because they were coming up short on the strength test. What was so interesting, though, was that in practice, it turns out that one of the most important skills a firefighter needs is not so much the strength to drag an unconscious person from a building, but, far more commonly, the ability to coax someone who’s in danger and is terrified to come with them. Apparently, many women turn out to be far more persuasive than men – highlighting the importance of selection based on real-world skills, rather than legacy stereotypes.
Space flight offers another striking example of this phenomenon. In the context of a recent Tech Tonics podcast interview with Dorit Donoviel, director of the Biomedical Innovations Laboratory at the Center for Space Medicine at Baylor College of Medicine, I had told Dr. Donoviel about my lifelong interest in astronomy and space, about launching Estes rockets and my love of the National Air and Space Museum and above all, about my affection for the heroism captured in the movie The Right Stuff, an all-time favorite.
In response, she laughed, and told me how “old school” that thinking was. When the space program started out, she explained, there was an exceptional degree of risk involved, and astronauts tended to be selected from the ranks of fighter pilots – because, in her words, they had “the skill sets and the cojones.” But today, she said, things are different – in large measure because the “space program is a lot safer than it used to be.”
Consequently, Donoviel explained, “Today what we’re looking for is less of the sort of alpha-male pilots, and more of the sort of scientists and engineers, geologists and earth scientists, folks who can work together in a cohesive manner in a team.”
Moreover, she added, the astronaut of the future needs to be able to endure long periods of boredom and the prolonged lack of stimulation – in many ways, the opposite of high-adrenaline “seat-of-the-pants flying” that in some ways characterized the early astronaut missions.
In space travel, as in firefighting, our notion of what constitutes the right skill set has evolved appreciably.

Elon Musk as Heinlein’s Delos D. Harriman – “Selling the moon is just what Musk is doing”
I suspect I’d recognize a lot of the books in Colby Cosh‘s collection, as we’re both clearly Robert Heinlein fans. In a column yesterday, he pointed out the strong parallels between Heinlein’s fictional “Man Who Sold the Moon” and his closest counterpart in our timeline, Elon Musk:
Written between 1939 and 1950 for quickie publication in pulp magazines, the Future History is a series of snapshots of what is now an alternate human future — one that features atomic energy, solar system imperialism, and the first steps to deep space, all within a Spenglerian choreography of social progress and occasional resurgent barbarity. It stands with Isaac Asimov’s Foundation trilogy as a monument of golden-age science fiction.
[…]
The result, in the key story of the Future History, is an uncannily accurate description of the design and launch of a Saturn V rocket. (Written before 1950, remember.) But because Heinlein happened not to be interested in electronic computers, all the spacefaring in his books is done with the aid of slide rules or Marchant-style mechanical calculators (which, in non-Heinlein history, had to become obsolete before humans could go to Luna at all). Heinlein sends people to colonize the moon, but nobody there has internet, or is conscious of its absence.
Given that his ideas about computers were from the pre-computer era and even the head of IBM thought there’d be a worldwide demand for a very small number of his company’s devices, that’s not surprising at all. In one of his best novels, a single computer runs almost all of the life support, heat, light, transportation and communication systems on Luna … and is self-aware, but lonely. In later works where computers appear, they tend to be individual personalities or even minor characters, but they’re anything but ubiquitous: powerful, but rare.
I suspect the lack of an internet-equivalent derives both from the nature of his conception of how computing would progress and a form of the Star Trek transporter problem – it solves too many plot issues that could otherwise be usefully woven into stories.
The “key story” I just mentioned is called “The Man Who Sold The Moon.” And if you’re one of the people who has been polarized by the promotional legerdemain of Elon Musk — whether you have been antagonized into loathing him, or lured into his explorer-hero cult — you probably need to make a special point of reading that story.
The shock of recognition will, I promise, flip your lid. The story is, inarguably, Musk’s playbook. Its protagonist, the idealistic business tycoon D.D. Harriman, is what Musk sees when he looks in the mirror.
“The Man Who Sold The Moon” is the story of how Harriman makes the first moon landing happen. Engineers and astronauts are present as peripheral characters, but it is a business romance. Harriman is a sophisticated sort of “Mary Sue” — an older chap whose backstory encompasses the youthful interests of the creators of classic pulp science fiction, but who is given a great fortune, built on terrestrial transport and housing, for the purposes of the story.
