Some Sunday Thoughts-Thanks For Stopping By

‘The same idea occurs in Schopenhauer, for whom the truth of the world is Will, which cannot be represented in concepts.  Schopenhauer devoted roughly 500,000 words to this thing that no words can capture…’

‘…I too am tempted to eff the ineffable.  like my philosophical predecessors, I want to describe that world beyond the window, even though I know that it cannot be described but only revealed.  I am not alone in thinking that world to be real and important.  But there are many who dismiss it as unscientific cast of mind are disagreeable to me.  Their nerdish conviction that facts alone can signify, and that the ‘transcendental’ and the eternal are nothing but words, mark them out as incomplete. There is an aspect of the human condition that is denied to them. ‘

Scruton, Roger. Effing The IneffableConfessions Of A Heretic. Notting Hill Editions Ltd, 2016. Print. (Pgs 87 & 88).

Personally, I’m not sure that all naturalists and people in the sciences I’ve known wish to reduce the world to strictly mathematical laws, nor consign all domains of human endeavor to ‘non-science.’

Some people, I suspect, have the onboard wiring and have pursued learning which make them profoundly interested in order, patterns, and logic. Some people are just really smart and dedicate themselves to a particular problem or two, maybe possessing the genius and courage, even, to define a new problem after years of hard work of mastering a field, leading to genuine new knowledge.

I am grateful for the Mars Curiosity Rover, and the hundreds of engineers that worked for much of their professional lives to land this thing on Mars.  It’s still yielding valuable data.

But, I”m guessing there’s lot of waste and bureaucratic stasis at NASA. Perhaps a similar regression to the mean within institutions towards narrower ideas and ideologues happens here, too (if only x were removed, y will occur).

I see such outcomes partially caused by the decay of things, partially by design, and partially as a process of secularization (beneath the idealist and systematist lie human nature and reality). Such incentives don’t necessarily lead to leadership by the most knowledgeable, but over time, rather to leadership by administrative fiat and distant political winds.

Now, there’s arrogance, hubris and false pride to be in all of us, to be sure, and many sharp thinkers are no exception (in some cases the bigger the brain (or ego), the bigger the fool).  I don’t find foolish and/or earnest conviction in any short supply on this Earth.

To be fair, I don’t think this proves, nor does Scruton even attempt to prove, that the ineffable, therefore, exists (or if the ineffable does exist, as it reveals itself to us, that it requires saying or expression through us, nor through Handel or Bach or post-Kantian German thinking).

Such expression surely offers me consolation, though, for I take refuge in works of art.  I am profoundly grateful to walk at evening and listen to a few minutes of music:

I am profoundly grateful that I may share in someone else’s pain, suffering and disconsolation, across centuries, transmuted into an act of beauty and wonder, through a centuries-developed form and method (an orchestra is rather a thing of technical achievement, too, just as is a store-bought guitar or a Korg).

Sure, there’s much epistemological ignorance amongst some in the sciences and, frankly, within all of us.

Come to think of it, I think most of us manage one or a few things well, and mess up at least a few areas of our lives without even trying.  It’s also very, very tempting to talk about that which we know very little (this blog, for instance), as though something is known.

This may make me no more than a 2nd or 3rd rate idea man, taking, essentially, more than has been given.

For today, I suppose this will do.

For A Reader-Some Martian Information From A Layman

Solar radiation: We live within the envelope of Earth’s electro-magnetic dynamo, protected from the life-destroying short-wave radiation our star is constantly spewing.  Over time (billions of years) this has helped create a relatively stable atmosphere and biosphere; stable enough for the life we know on Earth.

Despite this stability, of course, we know the star-energy we eventually consume as food and water to be scarce as such conditions are coded at the cellular level (and since we’re being depressively realistic, there’s vulcanism, earthquakes, cold, heat, other people, parasites and viruses to contend with). Such facts define us as does the occasional catastrophic event and the eventual catastrophe awaiting each of us.  There’s love, friendship, knowledge, music, hope, beauty and a whole world to explore.

Okay, enough of that for now.

Zero or altered gravity:  On the surface of Earth, we live x units away from a mass ball at the bottom of a gravity well.  In space, we wouldn’t feel this force at all, and on Mars we would feel it about 40%.  What if blood vessels contract/expand or slowly atrophy in zero Gs for reasons yet unknown?  What if this dims your vision slowly, over time, and impairs cognitive functioning, especially during the reproductive process, pregnancy or early childhood?  Wouldn’t you like to know this before it starts happening to you on the six-months-plus journey to Mars?

Once we know about such problems, we can figure out some solutions.

If there is life on Mars (a possibility, still, as of 2019), it’s probably microbial, living on an energy source beneath the surface.  Up top, all that solar radiation has created a toxic layer of perchorates, oxidized, rusted dust and rocks, apparently hostile to life as we know it.

Imagine a place colder than Antarctica, drier than the driest desert, with so little atmosphere the atmosphere’s barely there.  The EM dynamo and envelope petered out long ago.  You look around and see a barren landscape, familiar yet strange; alien.

Imagine, one morning, stepping from a rover on an exploratory mission, feeling a deep  nervous tension and excitement.  You focus in on the scripted tasks and procedures the next few minutes require.

You know that if your suit becomes compromised, your blood would alternately freeze/boil and you’d die almost instantly.  You know some little, unplanned problem can become a big problem.  Any sort of help/supply lines would be pretty much impossible, at least six months but at least a year in coming, and probably not coming at all.

Yet, here you are:

As posted: It looks like Gale Crater has its advantages.

Research papers here. A summary of some of what’s been found so far:

‘Research suggests habitable conditions in the Yellowknife Bay area may have persisted for millions to tens of millions of years. During that time rivers and lakes probably appeared and disappeared. Even when the surface was dry, the subsurface likely was wet, as indicated by mineral veins deposited by underground water into fractures in the rock. The thickness of observed and inferred tiers of rock layers provides the basis for estimating long duration, and the discovery of a mineral energy source for underground microbes favors habitability throughout.’

You can also watch a 12/05/13 press briefing from JPL discussing those papers above.  These rocks are much newer than the older wet period theorized.

They’re more focused on the search for organic carbon, now, within the environments they’ve discovered.

Why was Mt. Sharp chosen for the Curiosity Rover landing site, and what about those rounded stones that it photographed, indicative of long ago ankle to hip-deep water?  If the Martian surface is likely so full of perchlorates and life-hostile, irradiated soil, what are the chances of pockets of microbial life below ground?

The discussion later moves to Venus, Jovian moon Io, and the Chinese lander on the dark side of the moon in the final minutes:

Event Horizon discussion with Emily Lakdawalla.

Imagine sub-freezing temperatures and free radicals bombarding the near atmosphere-less Martian surface (oxidized and rusted red, barren), but below the Martian surface lurk big blocks of briny ice; ice with freezing cold, incredibly salty water around them and maybe just enough O2 to support some microbes.

Worth thinking about.

What are you doing with your imagination?

‘Due to the scarcity of O2 in the modern Martian atmosphere, Mars has been assumed to be incapable of producing environments with sufficiently large concentrations of O2 to support aerobic respiration. Here, we present a thermodynamic framework for the solubility of O2 in brines under Martian near-surface conditions. We find that modern Mars can support liquid environments with dissolved O2 values ranging from ~2.5 × 10−6 mol m−3 to 2 mol m−3 across the planet, with particularly high concentrations in polar regions because of lower temperatures at higher latitudes promoting O2 entry into brines’

Do you click through to videos found on a blog?  Probably not, so I’m putting this up for my own benefit as much as anyone else’s.  I was fortunate enough to attend a Curiosity Rover landing party at Boeing in south Seattle, which included some speakers from JPL (NASA’s Jet Propulsion Laboratory) discussing the mission.

There’s so much science going on, and so many new discoveries, it’s hard to keep up.  Yet,  it’s also easy to overlook some of the data and evidence piling up which allow for an ever-expanding picture of what Mars is like.

Ashwin Vasavada, a JPR Research Scientist gave a presentation open to the public at the one-year mark, which included some very basic and very interesting questions from the audience.  Easy to follow:

Just some links:

From a December 18th, 2012 mission status report:

‘NASA’s Mars Science Laboratory Project is using Curiosity during a two-year prime mission to assess whether areas inside Gale Crater ever offered a habitable environment for microbes. NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the project for NASA’s Science Mission Directorate in Washington.’

-Unlike Earth with its dynamic interior and tectonic plates, relatively strong magnetic field, thick and dynamic atmosphere etc., Mars is a bit like a time capsule.   With just over 50% the diameter of Earth, about 38% the gravity, and  less than 1% the atmosphere we’ll be able to get a much better picture of what happened during the formation of our solar system about 4 1/2 billion years ago as it’s much less disturbed.  The trip up the rock face in Gale Crater over the next few years is like a trip back through time.  What happened to Mars?  Did the Earth and Mars have common experiences?

Some more Mars facts.

A December 4th, 2012 livestream overview of the mission.  Ashwin Vasavada’s talk starts about min 15:25, and is pretty easy to follow for non-scientists and lay people like myself:

From NASA’s Mars Science Laboratory: ‘NASA Rover Finds Old Streambed On Martian Surface’

Full piece here.

The first real ‘direct’ observation of water:

“From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep,” said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. “Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we’re actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it.”

Apparently, it’s sedimentary conglomerate.  Rounded rocks smoothed by water and deposited in a cement like structure, which is now jutting above the surface as it lays in a large alluvial fan bed.  Comparison photo from Chile, back on Earth, of what appears to be a similar phenomenon.  The Rover is still headed towards Glenelg.

Video comparison on alluvial fans between Las Vegas and L.A. and on Mars, where the Rover sits:
