Juicy Planets

This is the one thousandth essay on this site. Let’s celebrate with a whiff of optimism. We found, for sure, three habitable planets. Close-by. And maybe four. Or five. Europa, Callisto, Ganymede, and Enceladus. They are all in the Solar System. Why habitable? Because they all have liquid water.

And massive quantities of it. Europa’s ocean seems greater in volume than Earth’s… by a long shot. Ganymede’s ocean maybe 800 kilometers deep… This is astronomy, in full, with its proverbial astronomical numbers.

Juicy Planets In The Habitable Zone

Juicy Planets In The Habitable Zone

The total land area of Earth’s continents is 148,647,000 square kilometers (57,393,000 sq mi), or 29.1% of Earth’s surface. This is just a tiny bit larger than Mars’ total area (145 million square kilometers). Mars has lots of water. However, except for (rock covered) glaciers and ice caps, most of it is ice mixed with the soil.

It is welcome news that planetary bodies close-by have plenty of water, and land. Europa’s land area is 30 million square kilometers. Ganymede is 87, and Callisto 73 million square kilometers. Thus the total land area of water loaded Jupiter satellites is 190 million square kilometers, much larger than the grand total of Earth’s continents. That’s plenty of room for human civilization to expand into.

As I related, civilizations come and go, and one of the main mechanisms, if not the main mechanism, has to do with the entangled exhaustion of increasingly impotent technology and waning resources. This is fully in evidence now in our case: although not all resources are exhausted, yet, others are exhausting: the CO2 pollution, and similar, entangled crises, have reached the stage of a mass extinction.

A race is engaged between the deployment of more renewable energy and multiple singularities from pollution and resource exhaustion.

Once, when still a child, I met a poet and philosopher from a family of poets and philosophers. He read some poems. I was impressed. The conversation, though, turned to space exploration. My youthful enthusiasm was quickly dashed. The poet told me that space would not help humanity’s problems. Actually throwing money at space prevented to feed children, he opined. Walking on the Moon was mostly a folly darkly connected to imperialism, colonialism, materialism, nihilism.

As a teen, but a teen experienced from having lived in Africa most of my life, who had endured through wars and coups d’état, I doubted the wisdom of the poet. (When I was 11 years old, I made a sing-song about a coup d’état enfolding in the African country in which I lived. Retrospectively strange…)

I knew very well that there are monsters out there. But then, again, I also knew monsters, properly handled, could learn to behave properly. A leopard entered an open hut I was sleeping in, and walked out (don’t ask me about what I view as my parents’ irresponsibility: there was just another child in that hut, smack dab in the center of a national park, full of panthers). I once walked around a bend on a dirt road, in the same national park, to find a lion spread all across said road, looking at me calmly. I did not panic, and respected away.  

Differently from the European poet, I knew the world was richer than just a zero sum (where what you put in is what you get out). I knew starvation was entirely due to war. If you don’t want children to starve, the first thing needed is a strong stater, with a constitution centered on human rights (instead of the Catholic or Islamist creeds).

As it turned out, in its rush to the Moon, and Mars, as ordered by its Guide (USA president JFK), NASA and its Nazi engineers, helped develop plenty of new technologies, from fuel cells to solar panels. Now Photo Voltaic Solar energy is, with wind turbines, the cheapest, safest form of energy (fossil fuels get more than 5 trillion dollars of subsidies, each year). In a way PV solar energy is feeding the world, and saving it too, being non polluting. Solar PV arose in space, to feed satellites with electricity.

To this day PV energy panels used in space are much more efficient than any used on the ground (but also much more expensive, as they use different very expensive materials). The research goes on: the requirements of space did not just bring Teflon.  The technological push impelled by space exploration keeps on going. The giant infrared telescope NASA wants to launch (with an Ariane V rocket!) has been delayed for years by setbacks while developing new technology to make it possible. Engineers have perfected the efficiency of space probes and solar PV, to do away with plutonium to energize them.

Far from being weird and unusual, expanding human civilization throughout the Solar System is the most conservative behavior to behold.

It’s revolutionary in the sense of evolving again, as we used to.

Indeed, how did our species arise? Our family, hominidae, arose from a separation from chimpanzee like ancestors. Basically, our distant ancestors were motivated enough to come down from the trees and imitate baboons (giant or not), and conquer the savanna. Giant baboons, who could weigh up to 200 kilograms, and stand two meter tall, besides being extremely dangerous, were probably an inspiration, as they dominated the savanna-park.

Conquering new land, and new environments, is what our species does. Our species shipped to Australia in prehistoric times, and conquered the Americas, and the Arctic, also in prehistoric times.

Now the juicy planets of Jupiter beckon. This summer, Europe attributed to Airbus the JUpiter ICy moons Explorer (JUICE), to launch in 2022, and NASA announced that its “Europa Clipper” mission was feasible. It will “clip” Europa’s atmosphere 45 times, to analyze it for organic materials.

Some may object that, before we conquer space, we could conquer the oceans. It seems an obvious extension from swimming. However, going to space means a difference of one atmosphere of pressure, just as going down ten meters in water. Going down in the ocean at its average depth, 6,000 meters, means 600 atmospheres of pressure, a much greater challenge than the one and only one of pressure difference space requires.

With present technology, extrapolated a bit, Earth’s life could be implanted in these icy moons of Jupiter, one way, or another. It’s imaginable that present day life, recently discovered 850 kilometers from the lighted ocean, under Antarctica’s ice shelves, could survive in Europa’s ocean.

And it will need to. It’s not just a question of our nature, and respecting it. Or of our tradition, Charles Quint’s “Plus Oultre”, and respecting them. It’s a precaution. We are using Earth far beyond sustainability. Yet, out there, in proximal space, lays in waiting another 230% worth of the entire land area of Earth, complete with abundant water.

After 1,000 essays on this site (and more on Tyranosopher.com), what’s the obvious verdict?

If you want to be popular, write about simple things, for simple people, in the most simple fashion. Cats, witchcraft, celebrities, flowers, home remedies, and logic for the mentally underperforming. People want to forget about their condition: those who are going to die do not salute me.

Another dismal conclusion is that censorship is strong, out there: the New York Times boast of having censored hundreds of my comments (they sent me an email about that). It’s more like thousands. The Guardian, a British daily supposedly on the left, just informed me I my comments were censored, because I am culprit of “blogging the Qur’an“. So the Guardian has decreed that Patrice Ayme, is a well-known… Jihadist? Complain about something will get you accused of it: one of the logics of the vicious.

The New York ran a long article on Islam Rape Kit, but systematically censored any direct quote from the Qur’an supporting that criminal habit. To blare as a subtitle that:

“ISIS Enshrines a Theology of Rape. Claiming the Quran’s support, the Islamic State codifies sex slavery in conquered regions of Iraq and Syria and uses the practice as a recruiting tool.” is alright. Claiming that ISIS claims the “Quran’s support” is fine. Demonstrating it is presumably “Islamophobia” (thus racism, thus censored).

Meanwhile, pretty much unfazed, I have been trying to think, as honestly as I can, precisely, and beyond (“plus oultre“) what has been said, on the most difficult problems, trying to find possible issues to them. Escapism, if you will, the hard way. As Montaigne caustically preempted, in the introduction to his “Essays”, paraphrasing:”Passant passes ton chemin, there is nothing for you here, Adieu.” (Amusingly, Montaigne, who was familiar with the most powerful, such as the future king Henri IV, was actually seriously manipulative in his essays, as demonstrated by the fact that he spent lots of pages crawling on his belly, singing the praises of most plutocrats… This is not the case here, as witness the evidence that I should have antagonized everybody by now.) 

Ultimately, I write just for my little girl, who has called me (with a slight twinge of irony perceptible) “the One Who Knows Everything”. That’s good enough, it’s the greatest honor, and all the meaning one needs in the world. Camus claimed one must find a meaning to rock and roll. Silly. Those who love a child do not need to impose meaning onto themselves. They have found it already.

One day, human children will bathe on Europa.

    On your 1000th, thanks for giving us so much. In 2010, a space odyssey, the ET says: all these world’s are yours, speaking of Jupiter’s satellites!

  2. stevedude Says:

    Late to the party, but congratulations nonetheless. Here’s to the next thousand posts and beyond. Thank you, gracias, et merci!

    • Patrice Ayme Says:

      Thanks Steve! As I told Paul, encouragements are pretty much the fuel of this site. This way I do not differ much from the average pet… But so it is. After all, it is not necessarily demeaning: quite the opposite, it means I am fueled by love…

  3. Paul Handover Says:

    Quite an achievement, well done.

    • Patrice Ayme Says:

      Thanks Paul, your encouragements are always appreciated. Things are a bit slow right now, as I try to reset my wild spirits in wild setting (restarted outside climbing with a dangerous solo, hahaaaaa…)
