Happy Valentine’s Day! The three traditional symbols of this holiday are (1) a voluptuous heart-shape, (2) Cupid, and (3) a pair of doves. The first of these—the shapely heart–is a medieval symbol, but the other two holiday symbols are much older and trace their way back to the ancient Greco-Roman world. The mischievous archer Cupid was the god of infatuation and besottment—with his phallic arrow, he is so ouvert that he is barely a symbol. In the world of Christian iconography, doves represent peace, divine revelation, and the holy spirit, however in the classical world they were the bird of Aprodite/Venus. Valentine’s Day is really Lupercalia—the fertility festival to Lupercus (Pan). In the modern world it (barely) masquerades as an acceptable holiday, but its wild roots are never far away. I get the sense these doves are really the amorous doves of Venus and not representations of peace.
To celebrate, here are some Valentine’s doves from Valentines throughout the ages.
Doves pulled the chariot of Venus and they nearly always attended to her. Their tenderness with each other and their ability to rapidly proliferate made them abiding symbols of love. Additionally, doves are uniquely beautiful and otherworldly and yet also commonplace. They can fly to the heights of heaven and yet consist on meager scraps in wastelands. Maybe doves really are a good symbol of love!
Ferrebeekeeper has long served Athena, the virgin goddess of truth and wisdom (although she is never the most popular goddess, she is certainly the BEST and is always is victorious in the end), and, in my time, I have also served Dionysus. All American are compelled to serve Hera for 8 hours every workday (except the super-rich, who serve her constantly). Yet Aphrodite has almost always eluded me. Springs come and go and the long decades pass, but love is elusive. Maybe some sacred doves will please coy Aphrodite.
In the meantime, Happy Valentine’s Day to everyone. I hope you find the love you are looking for in your life. Or at least I hope you enjoy these doves and maybe some chocolate!
OK, we have a lot to get through this week. We have a new president coming along, and even though this charlatan may well usher in the end times, he is certainly known for grabbing ratings (among other things). Also, last week, I promised to write about why I am having trouble with ‘Romance of three Kingdoms.” It is a book about deceit, trickery, and cruelty as the tools of leadership. Perhaps now is a good time to talk about its dark lessons. However before we get to any of that, today let’s take a quick trip off-world to our sister planet Venus (a planet which endlessly fascinates me) where some exceedingly strange developments have been in the works.
Venus is currently being monitored and observed by the Japanese Space Agency probe Akatsuki. On December 7th, 2015, the probe spotted a huge crescent wave 6,000 miles long in the atmosphere of Venus. The probe lost sight of the massive bow shaped phenomena as it moved through its orbit, and, when it returned to position a few days later, the wave was gone.
So what produces a 6,000 mile long super cloud on a planet already known for extreme fast moving clouds of sulfuric acid. Scientists theorize that this was a gravity wave. Gravity waves are not too be mistaken for the gravitational waves of deep space (which are caused by distortion of spacetime from supermassive objects). Instead a gravity wave is a wave propagated within a fluid (like air or liquid) through the effects of gravity. When water flows over a sandbar, gravity restores equilibrium on the other side–which causes a wave effect. This is a familiar pattern in all sorts of fluid dynamics–including clouds passing over mountains. It is believed that the giant crescent wave within the atmosphere of Venus originated from the atmosphere flowing over vast mountain ranges on the surface.
Even if this is not as unfamiliar a phenomena as it might deem when first hearing the name and looking at the pictures, it is very beautiful and it is appearing on a scale hitherto unknown in terrestrial parts (although the supermassive planets have their own bizarre cloud structures which put it to shame. for now lets just enjoy looking at the huge bow shaped cloud on the closest planet to Earth. Thanks JAXA for making this discovery! What will the strange hot caustic atmosphere of Venus do next?
I promised to write about Romance of the Three Kingdoms, a book which I am planning on reading this year (after bouncing off of its deep moral ambiguity once before). However before we get to talking about great literature and right and wrong and how to cynically manipulate people, let’s indulge in some completely frivolous daydreaming.
Longtime readers know that one of my favorite concepts for the not-so-distant future is the establishment of a floating colony in the skies of Venus. A variety of considerable factors make this seem more attainable than the Martian colony which everyone is always talking about (plus I like tropical swamps better than Arctic deserts).
Alas, I am not an engineer, and I cannot bring my dream closer to reality with a slide rule and a spreadsheet full of atmospheric measurements and rocket payloads…or with a thoughtful treatise about making plastics out of the chemicals present in Venus’ thick atmosphere…or with mention of the seemingly inexhaustible thermal energy on its surface. Yet I am imaginative, and perhaps I can share a powerful passing fantasy with you. The other day, while browsing goodness knows what on the internet, I came across the picture above and it struck me forcefully as a perfect structural component of Mary Rose or Constance [astronomical convention dictates that all features on Venus be named after women, so I decided to name my cities after my grandmothers…at least until I know what my billionaire partner wishes to call things]. I had to share the image with you, even though I have lost the real context of the actual inflatable structure 9avionic saftey equipment maybe? That doesn’t actually seem so far off).
First I imagined that this is the lifting body of the colony, which would be suspended underneath…but then it occurred to me that it might be the city (since breathable Earth atmosphere mixtures of gases float on the clouds of Venus). or perhaps it is an agricultural pod or a park or a laboratory, or a factory. Who can say what is in the lovely 4/5th torus, until we complete more of the schematics? At the moment, it is a concept piece…like the whole colony, but the world is filled with clever people, and some of them read this blog. let’s keep dreaming big! Imagine this sparkling with lights as a huge yellow storm boils up beneath and a cloud of drones and gyrocopters approach from a nearby fleet of zeppelin buildings…
Hey, did I tell you about Akatsuki? It was one of the thrilling space exploration stories of 2015—and it is just now becoming germane, but it did not get a lot of press attention in the west because of the holidays and because people were busy thinking about stupid trivia (including me). Akatsuki is a Japanese spacecraft/space mission designed to research and explore the atmosphere of Venus (its other name is Venus Climate Orbiter). The mission was launched in May of 2010 and the craft was supposed to go into orbit in December of 2010, but a catastrophic failure of the orbital maneuvering engine caused it to fly off into orbit around the sun (this failure was caused by a tiny salt deposit—which quietly says a great deal about the difficulties and dangers of space travel).
The Japanese space agency turned the probe to hibernation mode to conserve energy and waited…and waited…and waited. For five years, the craft flew through interplanetary darkness, quietly orbiting the sun as rocket scientists plotted and made corrections. Then, in December of 2015 the agency tried again. The combustion chamber throat and nozzle of the orbital maneuvering engine were horribly damaged (such a problem destroyed NASA’s Mars Observer probe in 1993) so JAXA jettisoned the craft’s oxidizing fuel and attempted to enter a strange elliptical orbit by means of four hydrazine attitude control thrusters. The rendezvous between Akatsuki and Venus occurred on 7 December 2015. Using four tiny thrusters not rated for orbital maneuvering, the spacecraft made a 20 minute burn and entered Venusian orbit! I wish I could make this sound more dramatic—it was a stupendously precise and superb piece of jerry-rigged rocket science happening around a different world. It is a miracle this craft is not a splatter on the baking surface of Venus. Kudos to JAXA!
The craft was originally slated to orbit Venus every 30 Earth hours, but its wild and bumpy 5 year journey to our sister planet changed the original plans quite a bit. In March of 2016, JAXA mission control finalized the craft’s elliptical orbit to take 9 days per orbital revolution. Planetary observations are slated to start in mid-April—right about now! Akatsuki is the only operational human craft currently at Venus. Its mission is to investigate Venutian meteorology with an infrared camera (we will be talking more about the insane Venutian atmosphere in a follow-up post) and to determine whether lightning and active volcanoes exist on the hot troubled world. This information may take a while to collate and access (considering that we are only now figuring out what the results of the last Venus mission, the ESA Venus Express, actually denote.
Anyway, stay tuned for more news from Venus! Maybe Akatsuki will be broadcasting some surprises about the little known planet next door.
It’s April 12th, “Yuri’s Night” when humankind comes together to celebrate our achievements in space…and to brainstorm about where we will go next. Of course at this precise moment we are having some temporary setbacks in space—but we’ll post about NASA’s space telescope trouble tomorrow. Today is about the glory and magnificence of space exploration. And there are plenty of news stories about that too. SpaceX has finally “stuck the landing” on one of its reusable rockets (and the past year’s drama of watching them nearly land on a raft and then blow up was pretty thrilling in its own right). A private firm is building an inflatable module for the International Space Station. NASA is moving forwards with its plans to build a space probe to touch the sun! And that is not to mention the many man robot probes running around the Solar System.
Solar Probe Plus (NASA)
However, today is also a day when we whisper our heart’s dearest wishes to the stars. The Economist has abandoned its fusty articles about central banking to lovingly describe a feasible interstellar space craft! Visionary engineers keep grinding ahead with plans for a space elevator (the brainchild of a different Yuri— Yuri Artsutanov). Tech billionaires are working on their asteroid mining project (at least on paper)… and NASA continues to talk of a Mars mission.
Yet all of this pales beside my near-future space vision—a plan which is as simple as it is breathtaking and incomprehensible. I want us to come together and hang a new society in the distant skies over Venus. At first it will be a crude plastic bouncy city, but, as we drop energy transfer cables down into the atmosphere and skyhooks down to harvest raw materials from the surface things should start to get more elaborate fast. We can make floating farms, forests, and oceans. All we need to do is get a plastics factory over to Venus and uh, solve the pesky problem of shielding our new society from deadly solar winds (a real problem on Venus, since it has no magnetosphere to speak of).

With this in mind, it is time to take a much closer look at Venus. So this is my Yuri’s Night resolution. We will be revisiting our sister planet at this site and reviewing everything we know about it. Since the first humans looked up in the morning sky and saw it as the brightest star up until now Venus has always been in our hearts—but these days we know some real and meaningful things about the morning star (wisdom which did not come easily). It’s time to review that information and find out more about our closest planetary neighbor. So hang on to your (heat resistant) helmets and get ready to visit this beautiful hellish sister world!
This thing, which looks like a sad cross between an ur-robot and a space probe, is Venera 3, a uh cross between an ur-robot and a space probe (Occam’s razor sometimes works for identifying weird historical objects). Although the probe did fail…in a way… it was hardly a sad object but rather a glorious milestone for humankind. Here is the story.
The Soviet Union launched Venera 3 from Baikonur Cosmodrome in Kazakhstan in November of 1965 (as “Days of Our Lives” first went on the air, crisis threatened British Rhodesia, and Björk was born). The probe was designed to fly to Venus and deploy a probe into the (then unknown) atmosphere of that world and ultimately land/crash (?) upon the surface. Venera 3 traveled on its interplanetary journey by means of a Tyazheliy Sputnik (65-092B) craft. It took the vehicle 5 months to hurtle through space to our nearest planetary neighbor. I said that the probe was a sort of ur-robot, but that is actually being pretty generous. The planetary lander contained a radio communication system, some scientific instruments and power sources, and a bitchin’ medallion with the U.S.S.R. coat of arms.
Venera 3 has the distinction of being the first manmade object to reach a different planet. That sort of thing is familiar now (though less than it should be), but I invite you to really think about how utterly astonishing it is. Unfortunately Venera 3’s landing was more or less indistinguishable from crashing: the communications systems failed before any planetary data could be returned (probably upon first contact with Venus’ nightmare caustic atmosphere and scalding temperatures). We only know that Venera 3 is now a heap of melted metal and slag on the surface of Venus because it fell into the planet’s gravity well. Where else could it be?
Regular readers know my fascination with our sister planet. I found the story of Venera 3 on the online Venus scorecard…it appeared after a great many more pathetic stories (Venera 1 and Venera 2 for example are still out there slowly orbiting the Sun—and the Soviet program only named missions after they had attained a degree of success). Ferrebeekeeper is going to be back looking at this scorecard. There are other stories worth telling in there with all the dismal explosions, telemetry failures, miscues, and melted probes. The successes—even painful successes like Venera 3 also reveal the story of Venus (insomuch as we know its story—for the world is still an immense mystery). There need to be a lot more home runs at the bottom of that scorecard.
Once again I have been thinking about the Namib Desert–the world’s oldest desert–which calls to me for reasons I cannot fully explain. I wrote about some of the Namib’s strange animals and plants…but one thing I did not mention was its ergs. This is because I did not know what an erg is, but today I looked it up and the concept is simultaneously horrifying and beautiful. An erg is a sea of wind-blown sand. This geographic feature is not unique to the Namib Desert—or indeed to planet Earth—but they do tend to be found only in vast & mighty deserts. Such a landscape is characterized by vast dunes—mountain-like sand hills composed of immense numbers of individual sand grains.
Geographers have seemingly fixed certain parameters on how large a sandbed must be to count as an erg—but I will let you look these up on your own—I think the word “sea” covers the scope of ergs. We are not talking about a child’s sandbox here.
The word erg derives from an Arabic word “arq” which means dune landscape. The Rub al Kali Desert “the empty quarter” of Saudi Arabia is a vast erg—the world’s largest. There are a multitude of ergs throughout the Sahara (as seen on the map below) and they can also be found in central Asia, the middle of Australia, and the Atacama Desert (which I also really need to write about). Ergs are less common in North America than in Asia and Africa, but there a few notable examples mostly in the Sonoran Desert, but also including the unimaginatively named “Great Sand Dunes” in Colorado.
The geology of ergs is quite fascinating as the dominant agent of erosion and change is wind rather than water. When wind activity shapes the surface of the Earth (or another planet), geologists describe the varying sorts of erosion, deposition, and weathering as “Aeolian processes” in homage to the ancient Greek god of the winds who crops up in the Odyssey and the Aeneid. Ergs do not just feature great dunes but also strange sand sculpted rocks and dry river beds.
As noted, ergs are not a phenomena exclusive to Earth, but can be found on other planetary bodies too (if they have silica and atmospheres). Ergs have been discovered on Mars where vast erg fields ring the polar caps. The Martian winds blow the ergs into bizarre patterns and shapes (usually I would say “otherworldly”, but that seems too pedestrian a word here). Venus also has ergs (discovered by the Magellan probe) and Cassini’s radar spotted huge parallel ergs on Saturn’s great moon Titan. Indeed ergs may be the dominant surface feature of Titan.
I have never been to an erg. There are none in Brooklyn (yet). However I would like to see one…although I admit to a certain amount of trepidation. They do not seem like places for life, and indeed they are among the most lifeless places on all of Earth. Ergs are beautiful but also terrible and dangerous. At least they should stay free of suburban sprawl for long enough for me to visit one (and it will probably be a very long time indeed before we cover the ergs of Titan with strip malls).
This is the Cameo Tiara, a delicate and lovely miniature crown of pearls and feminine cameos which is owned by…King Carl Gustaf of Sweden! However the Swedish king doesn’t wear it, but rather lends it out to women in his family when they are being married. The cameos were carved separately and gathered into a crown in the first decade of the nineteenth century when cameos were all the rage. The crown was a gift from Napoleon to Josephine (or at least it is assumed that that is how she obtained it). Since the fall of the First French Empire, the little crown passed through surprisingly few hands. Orders of Splendor, a blog dedicated to such things describes its history succinctly:
Josephine left it to her daughter Princess Eugénie, who left it to her nephew Prince Eugén. Eugen loaned it to his niece by marriage, Crown Princess Margaret, and eventually gave it to Princess Sibylla of Saxe-Coburg and Gotha when she married Prince Gustaf Adolf in 1932. Sibylla lent it to her sister-in-law, the future Queen Ingrid of Denmark, for a costume ball and ultimately left it to her son, King Carl Gustaf.
The pretty crown seems ideally suited to weddings because of the central cameo—but that cameo is itself the subject of minor controversy. To me it appears to be Venus teasing her son Cupid by holding some cherished object just out of his reach (archery equipment maybe…or a girdle or even a crown). Others. However, see it as a Psyche and Cupid—although frankly I enjoy Psyche and Cupid art when the two are more evenly matched in age (and when Psyche is not unwisely tormenting her spouse). Maybe the question adds charm and interest to the piece.
Whatever the case it is a beautiful little crown. I just wish we could see what is on the other four cameos on the back! The next time a Swedish princess invites me to her wedding I will be sure to ask (in a polite and cautious manner of course, the last thing I need is to be stabbed by some rich beefy Scandinavian nobleman).
In classical mythology Anchises was a prince of Dardania who found lasting fame as the mortal lover of the goddess Aphrodite. One day when he was hunting in the forest, she appeared to him disguised as a Phrygian princess. They made love for two weeks straight (!) whereupon she vanished–much to the distress of the besotted prince. Nine months later she reappeared to him in her full glory as the goddess of love…with a baby, Aeneas, who was fated to survive the fall of Troy and found Rome. Here is a splendid, splendid painting of their meeting which was made by William Blake Richmond in 1889/1890 at the zenith of nineteenth century painterly craft.
In the painting, Venus is not working very hard to conceal her godhood (although, uncharacteristically, she is garbed). Flocks of doves spring up at her feet. Sparrows fly everywhere like confetti and the dead winter woods burst into crocuses as she passes. Glowing hawthorn flowers frame her beauty like a halo of stars and a pair of adult lions bound through the woods in front of her to herald her coming. Yet these peripheral details are clearly lost on the gobsmacked Anchises whose focus is squarely on the goddess. His horn hunting bow has dropped to his side (although the top limb juts out in a not-at-all symbolic manner).
This lovely painting is remarkable for the way it merges seemingly incompatible contrasts. The larger-than-life mythical characters somehow fit in with the hyper realism of the forest in early spring. Likewise the glowing white and gold of Venus’ glowing raiment is starkly juxtaposed with the dark earth tones of the mortal world—yet somehow they go together. Her lambent robes seem to form a swirling nebula. Richmond lavished such effort on the details of this picture. Look at each perfect crocus or the endearing little Phrygian hat. You should blow the painting up and look at it full size—it is an appropriate Valentine’s Day treat.
Tomorrow I will write the obligatory annual post about whom we lost in 2014. It’s always a solemn occasion which highlights the passing of many eminent figures (as well as the passing of yet another year) and raises troubling questions about what is truly important. But before we get to the human obituaries, I wanted to write a quick eulogy for an underappreciated figure lost to little fanfare at the end of 2014. Last month the robot explorer craft “Venus Express” was destroyed by falling into the volatile high-pressure atmosphere of our sister planet Venus (an operatic end which overshadows all but the greatest human deeds). The Venus Express was a satellite launched by the European Space Agency in November 2005. It reached polar orbit around Venus in April of 2006 and has been continuously sending back data since then until November 28th of 2014 when the last remaining fuel in the satellite was used to lift it into a high orbit. Scientists planned on monitoring the space probe during its long drift down to the top of the atmosphere, but something went wrong and the satellite was thrown into a spin (which made it unable to contact Earth). It is now presumed destroyed.
Venus Express was the first Venus mission undertaken by the ESA. Now that the craft is gone, the human race has no functional probes or spacecraft on or around Venus until the Japanese climate orbiter “AKATSUKI” is scheduled to reach there sometime in 2015 (although there have been some problems with that mission and the planned rendezvous may be postponed…or never happen).
Venus’ atmosphere is believed to have once been much like that of Earth. This is certainly not the case now! The data from Venus Express is now being analyzed in order to ascertain what happened to transform Venus into a hellish greenhouse (and strip it of its magnetosphere). Maybe we can also analyze this data with an eye on future sky colonies as well. Venus Express discovered hydroxyls in the atmosphere of Venus. It also discovered an ozone layer and a high cold atmospheric layer which is possibly dry ice. It undertook a series of aerobraking experiments which could prove very relevant to future craft inserted into Venus’ atmosphere. We need someone to analyze this data and plan those future missions! Speaking of which, why doesn’t NASA have more exploratory missions planned to this nearest planet? We should try to put a long-term floating probe into the upper atmosphere of Venus itself! That would be an amazing accomplishment and it would tell us more about whether floating sky colonies above Venus would even be possible. Nothing is more alluring than Venus! Let’s honor the Venus Express by learning from it and sending some more missions there pronto!
