Ongoing Strangeness in Space

Apologies for the long absence of Invisible Words...alongside a geographical move, I thought I'd take a sabbatical to escape the high strangeness of 2017, but apparently it just gets more and more bizarre.




The tail end of 2017 brought the appearance of interstellar interloper Oumuamua , which made me think of a galactic stone skimming the cosmos - and why didn't anyone photoshop the Silver Surfer onto it ?




Then I decided that no-one would 'get' the reference, and what had comics to do with actual space, anyway ?
So the post languished, unpublished, in blogging limbo...
Then, yesterday, reality imitated art again
Kudos to Elon Musk and Space X

Two boosters make perfect touchdown

The payload of this test- run for SpaceX Heavy was a Tesla Roadster car - manned by a dummy in Space X garb.
I wonder if inspiration was taken from the opening sequence of the 'Heavy Metal' movie from 1981,
featuring an astronaut in a Corvette, which he pilots to Earth from space.
There are slight differences, though - the film car is dropped from a Space Shuttle-
and it doesn't play 'Space Oddity' * - but let's not be pedantic
The fact is, there is a car in space, manned by a dummy in an astronaut suit, heading for the Kuiper Belt.


Heavy Metal movie 1981



I'm sure the debate will rage for decades as to whether a car in space is a good advert for humanity. Personally, I think it's a massive ego trip/ publicity boost for Elon Musk, but also a great memorial for the previously overlooked genius Nikolai Tesla...so I'm conflicted.
Despite any misgivings, though, the synchronous landing of the two booster jets was a hugely impressive feat of engineering / physics .
The future is definitely now.
I await the responses of other players in the new 'space race' with trepidation...
Let's just hope that it doesn't create a cosmic junkyard of adverts orbiting for eternity...
Final words to the late, great Carl Sagan - obviously photoshopped, but still relevant...

Response to previous attempted commercialisation ?

When Stars Collide, Hyperloop Pods, Propellors and Quantum Catapults

Apparently, half the missing matter in the universe has been found.
I breath a sigh of relief, as I'm sure we all do.
Personally, the idea of dark matter and black holes gives me a sense of deep dread.
All that nothingness...(shivers)

One hundred and thirty million years ago, when dinosaurs roamed the Earth, two neutron stars collided.
In August, the signals from that event reached Earth, and became the first ever visual and gravitational record of such a cosmic cataclysm.
The visual and gravitational records arrived within 17 seconds of each other, which is pretty damn good for a journey spanning aeons* of time...

The image below looks underwhelming, but don't forget that you're looking at an event that took place long before we existed...

NGC 4993     When Stars Collide                   NASA/Swift
Personally, I'm still reeling with the simple fact that telescopes are time machines...
What we need is a quantum catapult, enabling us to cross the vast divide of space and time.
I'm working on it, but I need more elastic for the catapult.
It's a minor inconvenience - I'm sure Elon Musk could sort it out - speaking of whom, in a recent discussion of his hopes to use rockets as glorified 'airliners' on Mars, he displayed a masterful use of terms like 'rapid unscheduled disassembly' (rocket explodes) , and ' ...getting somewhere in thirty minutes by rocket...will be negatively affected if ...' you might die', is on the ticket.'
Fear not, though, as current tests for his (Earthbased)  hyperloop system are exceeding their own speed records, and it won't be long before intercity journey times are vastly reduced.

Google have expanded their maps to include places in our solar system: enjoy, but please don't confuse them with your own GPS...

'Propellor' imaged by Cassini    NASA

Remaining with our own corner of the cosmos, I found this article interesting, as it ponders a few discoveries of the belated (do we use this term for a spacecraft? ) Cassini, particularly the interesting 'propellors' created by moonlets in Saturns rings.
A world with moons named from figures of Greek mythos , including Janus, Pandora, Atlas, Dione and Prometheus is always worth revisiting, although my personal favourite is the little oddity known as Pan...


35km wide Pan...


Don't forget there is a little time left ( closing November 1,2017 )  to include your name on the Insight flight to Mars - get your boarding pass here
Not sure if I got a wing seat, knowing my luck, I'm probably in baggage...


...but I'll  see you there

Dusty Stars, Colonies On Mars, And The University That Wasn't


Eugene Cernan, last lunar mission, Apollo 17, 1972

Continuing from last weeks thread about developments in space travel and the race to Mars, it seems that the Trump™ administration has pressured NASA to go with lunar projects, as a 'stepping stone' for Mars.
Given the commercial edge introduced by Elon Musk, it should make for a busy and fruitful time. It's good to see progress - after all, it's been over forty years since the last moon landing.

My Mars boarding pass! Send your name to Mars! Follow the link !

In a blow to the ' Dyson Sphere' theory of the mysterious dimming of Tabbys star, this article tells us of a possible dust-cloud which could have the same effect
Mildly disappointing, but I'm glad that the mystery seems to be solved, rather than wasting time entertaining fantastical theories; speaking of which, a popular conspiracy theory which tied in with cyberpunk 'The Matrix', was the idea that the world we live in is only a computer simulation. Not so, according to physicists at Oxford University. The argument (based on the computational requirements) is convincing. My problem with it is the fact that 'Oxford University' is a matriculation body which oversees the exams for all the colleges in Oxford, it is not a 'university' at all; so the theory that our world does not really exist is disproved by a university that does not really exist.

Interesting article here about the proliferation of potential ocean worlds in our solar system - including some love for the sadly overlooked Saturnian moon Dione, which was overshadowed by the discovery of plumes of water on Enceladus and Europa.

Moon Colonies, Telescopes On Volcanoes, And Ancient Collisions


It's all systems go for Elon Musk, who is eager to get people on Mars.
His latest suggestion, the BFR (no prizes for guessing the acronym) can accomodate 100 people and will be used to create a lunar staging post , apparently.
His words appear designed to steal a march on NASA, whose SLS was to be similar - but their hands are tied , certainly in regard to funding and bureaucracy.
The flipside of that coin is pressure from the Trump™  government to accelerate the process of putting people on Mars.
Taking a step back from the politics, I'd say that having a proven player in the field ( Musk has multiple succesful landings and relaunches of the Falcon 9 rockets to his credit, as well as the Space X cargo missions to the ISS) can only be a good thing.
My confusion stems from the 'space race' angle - given that NASA have already announced a joint mission with Roskosmos : I'm pretty sure that this is just muscle-flexing as a demonstration of the prowess of Space X, and the fact that NASA are no longer the only game in town.
After all, it can't possibly be a  new space race, given that Trump™ and Russia are allegedly on the same side...

The downside of this posturing is the lack of any realistic plan for a sustainable colony.
Colonising the moon would surely be the logical first step. Recent discoveries point to the existence of a great deal of water which could sustain life systems and provide fuel for further planet hopping.

Enough of my idle conjecture - the spirit of the Space Treaty of 1967 looms large in this picture
The moon is to all intents and purposes, a dead world-on the surface...which brings us to the mystery of the subterranean lava tubes, and a possible sub-surface body of water.

A fourth gravitational wave has been detected using the two observatories in the USA, and Virgo, an observatory in Italy - giving an image of the 3D shape of the wave, and allowing triangulation for the precise location of the event (the collision of two black holes 1.8 billion years ago).
Personally, I wish I could remember the location of objects I put down five minutes ago.

P.S. As I finish this piece, I learn that the creators of  LIGO have just deservedly received the Nobel prize for physics

Recent solar flare activity caused fluctuations on Mars, and a resultant worry about safety for future explorers.
I wonder whether gravitational ripples contain similar disruptive potential - the one mentioned above involved a combined mass of 53x our own sun, a stupendous amount of energy .
At a distance of 1.8 billion light years, any effect here would probably be negligible - would you notice a tremor on a single sheet of paper on your desk ?


The James Webb Telescope has been pushed back to a spring 2019 launch, which, considering the original proposed date was 2011, is a wee bit late...
Staying on the subject of controversial telescopes, a proposed new telescope has fallen foul of indigenous Hawaiians. The dormant volcano Manua Kea is the proposed site for the telescope which will be capable of seeing 13 billion years into the past.
Despite protests, the telescope is going ahead.

Eclipse, Distant Probes And The Vanishing UV On Venus


Eclipse spex from 1932



Okay, so this post is happening out of sync, but this is often the case in life - today is the day when a total solar eclipse is occuring from coast to coast in the USA, so happy viewing !



London eclipse viewing 1927

In other news, Elon Musk joins over a hundred 'robotics experts'* warning of the dangers of autonomous killer AI, as we head blindly into a future where 'The Terminator' is more than just a movie...I touched on this in a post I made in 2015

* I tried to get clarification, apparently there are over 100 AI and Robotics Experts, but no further details.
Sadly, no advice on how to actually become an 'expert' in the field of robotics.
I'm sure that my past experience with models of Robby the Robot , Gort, Maria from Metropolis, and a Dalek should count...
( pause for a moment as I am corrected that Daleks actually contain biological entities therefore don't count unless you include 'synths' like the 'replicants' from Bladerunner)

Maria - technically a replicant, for pedants of robotics

Meanwhile, far out in space...

Yesterday was the fortieth anniversary of the launch of Voyager 2 - Voyager 1 was launched on September 5th , so the official celebrations are next month.
The reason for the lack of orderly sequence was due to Voyager1 being sent on a different trajectory.
This links to a nice piece about those who are still tracking the intrepid Voyagers - which are not due anywhere near another star for 40,000 years...don't wait up


NASA will soon launch a probe tasked with discovering the nature of exactly what is absorbing UV light in the upper atmosphere of Venus - personally, I think aliens love a bit of blacklight rave...

Our Watery Moon, The Inevitability Of Life, And The Height Of A Sheet Of Paper


Recent reports tell us that there is an abundance of water on the moon , more than was previously thought
Time for a re-think / return to the moon ?
Sub-lunar bases ?
At a mere 230,000* miles distant, it's a lot closer than Mars - and with possibly as much water as Earth- (beneath the surface), I say that we should go for it.
Not to be outdone, we hear evidence of ancient bodies of water on Mars.

It appears that particles have been detected in the atmosphere of  Titan which could serve as the building blocks of life - speaking of which, this article asserts that life on Earth was an inevitable result of physics, rather than a biological fluke...

On the subject of moons, the first exo-moon has possibly been discovered - it's four thousand light years distant, but hey- its an exo-moon.
My enthusiasm is muted, as I ponder the many unexplored moons in our own solar system.
Still, it's a new thing....even though it has not yet been confirmed -  infact the whole thing was made public on social media by a third party, thus forcing the hand of those involved, and creating a premature media hype.
This is the downside of social media.

A sheet of paper- relevant ...
My personal interest is in the burgeoning world of quantum mechanics.
I'm not smart enough to fully grasp what's going on, but that's part of the wonder.
The fact that it seems to defy accepted laws of physics,
whilst allowing for almost magical interactions,
is what attracts me to it.
The sense that there is much more to come;
that there is a missing key somewhere...
I think we have problems even describing this new ' realm '
For instance :

Excerpt from this article :

Mir Faizal, one of the three-strong team of physicists behind the experiment, said: “Just as many parallel sheets of paper, which are two dimensional objects [breadth and length] can exist in a third dimension [height], parallel universes can also exist in higher dimensions.”

Surely even a humble sheet of paper has height ?
Which means that a sheet of paper is not two-dimensional, technically.
My assertion is that this metaphor is clumsy.
We need to stop thinking in terms of human scale.
Our visual perception is limited
Which is why we have aids to vision;
Spectacles, contact lenses,
Microscopes and telescopes.
I don't think we'll ever truly understand the quantum world
Until we stop making comparisons
And there's the rub - without comparisons, how can we define something enough to understand it ?
Until next we meet...

Red Planet, Red Dragon And The Red KBO

Since the Pluto flypast on July 14 2015, New Horizons has been hurtling through space at approximately 32,000 mph, heading for its next rendezvous - Kuiper Belt Object MU69.
The report I linked is a tad speculative, as recent attempts to observe the object drew a blank - it remains uncertain whether it is a single object, or a cluster of smaller space rocks - all that is known for sure is that it is red.
Although which particular shade remains uncertain...
Artist impression               ©NASA/JHUAPL/SwRi

Regardless, New Horizons powers onward through the bleak vastness of space, aiming for a rendezvous on New Years day 2019
I must set my alarm...
Seriously though, I'm still trying to get my head around the sheer distance being covered.
That's another year and a half at 32,000mph.
Travelling 24 / 7
Without even a pitstop.
Damn

Speaking of things that move quickly...
Elon Musk may or may not have permission to build a hyperloop between Washington D.C. and New York.
Transporting people at 700 mph  would certainly ease the pressure of road traffic and the carbon footprint of flights...
staying with the innovative Elon Musk, his Dragon outfit are reworking their Mars landers.
This was reported widely as a complete withdrawal from commercial landings, but apparently it's just a re-design...

Meanwhile, those pesky alien signals...

The latest on the signal from Ross 128, is that it comes from a geostationary satellite.
However, there are still uncertainties .
At least it's not the microwave oven , this time...


Meanwhile, on Mars...   ©NASA/JPL





It has been asked of NASA, whether there were ancient civilisations on Mars.
Personally I hope the answer is yes, and the atmosphere vanished due to unchecked global warming...

Apologies for that outburst.
No more politics, or conspiracy theories...I promise !
Well, that's what the martians said...

Hell and High Water

© Flickr / SpaceX

Blimey, we've got a unifying theme this week - well , I think so - on Monday last, NASA announced the discovery of water plumes erupting from the surface of Europa
Personally, I wasn't too impressed, as we'd already heard of similar plumes on Enceladus .
Perhaps the most impressive thing is the sheer scale of the water jets - up to 125 miles / 200 km above surface level.
So, pretty darned impressive.
Enough so that we already have an illustration of a SpaceX craft there.
Of course, the elephant in the room is the fatal dose of radiation levels on Europa , courtesy of  Jupiter .
Not much chance of a quick selfie before imminent death...

Likewise, the recently mooted ocean beneath the surface of Pluto may be up to 62 miles / 99 km deep - That's a lot of sea.
The deepest part of our own oceans is a mere 7 miles / 10 km .
On the subject of oceans,  rising sea levels present a very real threat to NASA
Time to find a new launch pad !
Launch pads could be a wise investment, what with the increasing noise about the colonisation of Mars / the Moon / deep space.
The rockets currently being displayed by Elon Musks Space X and Jeff Bezos Blue Origin appear to be engaged in a ' mine is bigger than yours ' routine, with operational capabilities coming a poor second...
Still, healthy competition can only lead to better designs, surely
Speaking of designs (see what I did there?), it appears that ostrich eggs are marked with protein dna strands going back a long time.
I'm not sure what this means in the greater scheme of things , although there's probably a direct link to a Jurassic World - type scenario, where we happily watch dinosaurs with colourful feathers tearing each other apart.


 From Earth, we move inwards towards Mercury where we have been surprised to learn that there is tectonic activity happening there now - and also, it's shrinking - hardly surprising , with an average daytime temperature of 800 degrees farenheit.
Pretty hellish, then - but still active.
I find it somehow comforting knowing that worlds we previously considered geologically dead, are very much active.
We have Mercury, wilting in the sun, and Pluto with its beating heart is far from being the distant ball of windswept ice that my childhood imagination conjured...

POSTSCRIPT

Rosetta has ended its mission . After an epic 6 billion-mile journey, the Rosetta craft has descended to the surface of Comet 67P . The media is awash with words like crashlanding, and such - but at only 1 mph, it's hardly a spectacular finale.
Personally, I still wonder why it was not simply left to drift in space , perhaps locked into the comets orbit forever ?
After all, surely theft of industrial secrets isn't an issue in space ?
On the other hand, you can never trust those pesky aliens.
Perhaps we should build a Space Wall...

Notes From Anthropocene Man - The Gates of Hell, Falcon 9, and Supermassive Black Holes

STOP PRESS!

As this micro blog goes to press, Space X made history today by launching the Falcon 9 rocket to restock the ISS and then landing the first stage booster with pinpoint accuracy on a barge / 'droneship' in the Atlantic !
History is made !
Meantime, the Dragon craft is docking with the ISS to replenish supplies , and deliver an inflatable extension !

The West Coast  droneship used for the landing
It is a piece of history now, and surely the first step in a new, commercial, space race.

The image below appeared on my FB feed as a timely reminder that we see everything from a human scale, but in the grand scheme of things, we really are miniscule. Further feelings of insignificance came with the announcement of the discovery of a supermassive black hole in an otherwise empty corner of the universe.
The very phrase ' empty corner of the universe' is surely a euphemism...

Endeavour leaves Earth for the final time.          Pic NASA
I find it tempting to laugh at the ludicrous terminology - 'Supermassive', not just ' large' .
'Supermassive' black hole applies to anything over the size of ten billion* suns.
This one is the size of seventeen billion suns, so it's quite big, then.
but not the biggest.
This led me to wonder how they classify black holes , but I confess I'm none the wiser ...apparently the naming convention is ' primordial, stellar and supermassive' .
If you want to ponder, the link is here.

If you just want to see some great images from our solar system , the link is here, with thanks to The Atlantic.com

The giant listening 'ears' of SETI are being redirected.
The latest thinking is that intelligent life, should it exist, is more likely to be found in the habitable, or 'goldilocks' zones of planets in a tight orbit around red dwarf suns.
This information was gathered by the Keppler mission, and given that three quarters of the stars in our own Milky Way are red dwarf stars, that makes them much more practical (i.e. closer to home).
I laughed when I read the phrase 'They are the dim bulbs of the universe'.
This made me sit up, though - why so many red dwarf stars  in our galaxy ?
Are we a dying galaxy ?
Anyway, I hope the revised SETI search produces results - although I prefer another theory which states that our reliance on radio waves as a communication carrier might itself be at fault.

I also hold the belief that advanced alien civilisations might be hiding rather than attempting to communicate.
Who can blame them ?

MEANWHILE , BACK ON  EARTH...

Apparently the new, more energised world of the Large Hadron Collider leaves us open to dangerous possibilities .
Even Pope Francis has spoken out, saying " Scientists risk opening the gates to hell ".
If you ask me (or any old gamer) it sounds like a script for Doom .

In which science unleashes the hordes of hell...    
Either way, there's no denying that with increased power available, the world of the LHC is necessarily getting stranger.
Which makes me wonder -
Is there a global strangeness index ?
Personally, I reckon the world is a lot stranger than it was , but my Googling of the term ' Global Weirdness' only turned up a slew of Climate Change info, which is a frightening reality , but not 'weird '.

IN OTHER NEWS...

NVIDIA are developing supercomputers capable of intricate 'Deep Learn' style Artificial Intelligence.
The aim of this is to develop a system which approaches problems from a variety of angles, much as we humans do.
I only hope the resultant Artificial Intelligence doesn't decide to wipe us out and reboot...which brings us to the title of this post .

Apparently we are living in the Anthropocene era, when our impact on the Earth is unavoidably altering it - and not for the better.
As well as the obvious Climate Change, the search for rare earth elements is a potential eco-disaster.
These rare substances are essential components in smartphones and all things tech,, but do not exist in sufficient quantities to mine , except on the sea - bed.
The caveat is that wholesale destruction of fragile marine ecosystems is necessary to procure enough of them.
Of course, it's possible that many asteroids contain abundant 'rare-Earth' minerals - which, along with todays successful landing by Space-X, tells us that the new 'Space Race' is on - hopefully without the political edge...
