Standing outside on Mars with a view to taking a refreshing breath of fresh freezing cold Martian air whilst chatting about the stupendous view of neighbouring planet Jupiter might leave you wishing your body contained something else other than blood – seeing as it would repay you for the ill-thought up idea of going outside without a space suit by boiling you to death. You wouldn’t have too much time to converse about the dumb-founding beauty of the view of Jupiter as having been dumb enough to go outside in the first place and boil your blood you won’t last a matter of seconds anyway. This slightly pressing problem might possibly give you the completely understandable desire to have a good old scream before you die but even that isn’t going to go to plan. Nobody will hear you. Not least because most people wouldn’t be dumb enough to go outside on the Red Planet in the first place. But also, because the Martian atmosphere consists almost completely of carbon ­dioxide – 95% to be precise, and it does an awesome job of absorbing vibrations – such as those produced by your vocal cords. So, not only is screaming a waste of the precious time you have left, but if you thought you could accompany your ill-fated visit for fresh air on Mars with the ear-shattering sounds of your favourite music blasting out of that old ghetto blaster you brought with you from Earth – luck’s out. Krank up that volume all you like (but be quick – remember you have only seconds to live!) but it will still be little more than a distant tinkle of sound when you’re 10 metres away. Should you wish to sing along to it, the Martian air slows sound waves down to such an extent that you will produce nothing more than a hoarse, deep-toned croak.

What Would Your Voice Sound Like On Other Moons and Planets?

 

Scream, shout and yell into the vast and infinite realms of space in the ever-optimistic hope that someone or something might just hear you and do you think anyone or anything will cheerily respond to you? Maybe. But it always depends on whether anyone or anything can hear you!

Shouting your head off on another world doesn’t guarantee the noisy and well-loved sound of your terran-based vocal cords will resound in quite the same way in the atmospheres of other worlds comfortably nestled amongst the stars.

 

On the cosy home world of Earth sound whizzes happily and easily through the atmosphere thanks to a distinct lack of vibrations being absorbed by our gassy air. This is one of the particularly pleasing results of lots of nitrogen and just a tiny scrap of molecules of the carbon dioxide variety. The other handy bonus is of course that we can breathe…. Minor detail but worth a mention

Things start to get a little bit weird however, should you be posturing and screaming on worlds that are clearly not Earth. Different worlds, different atmospheric densities and all that scientific, technical stuff.

Most of us are probably at least vaguely aware, (don’t worry if you’re not, maybe for the best!), that “in space no-one can hear you scream!) This detail tends to apply too, on the majority of worlds in space. By and large they don’t have any atmospheres at all, and the ones that do have ridiculously thin and weedy atmospheres that contain so few gases that it would be impossible for them to carry even a single stingy little sound wave. Not that this would worry you overly much as you wouldn’t be able to breathe anyway and therefore wouldn’t be alive to be annoyed by it. If you happened to be a planetary native of that particular world specially adapted to create vocalisations on a super-sonic sound scale, of the nature that would shatter lesser worlds into a zillion pieces then you might just about manage to make yourself heard in some shape or form. Although it would most probably end up sounding something more like a whispering little sound in the vast void of outer space.

The UN Outer Space Treaty and Planetary Protection

What is Planetary Protection?

Planetary protection refers to ‘interplanetary contamination’ – protecting solar system bodies (i.e., planets, moons, comets, and asteroids) from ‘biological contamination’ by Earth organisms, (Forward contamination – the transfer of ‘viable organisms’ from Earth to another interplanetary body), and protecting Earth from the transmission of alien organisms, to Earth’s biosphere e.g. as a result of ‘extra-terrestrial sample-return missions.’ (Back contamination)

 

Why is Planetary Protection Important?

Planetary protection is a directive code in the blueprint of an interplanetary assignment, and is critical for several important reasons:  

• mirrors the unknown nature of the space environment 
• to safeguard our ability to study other worlds in detail, in their natural conditions 
• to prevent contamination that would make it difficult/impossible to find potential life on another world  
• to ensure that we take judicious safety measures to shield Earth’s biosphere in case it does.  

The UN Outer Space Treaty and Planetary Protection

The legal basis for planetary protection is located in Article IX of the United Nations Outer Space Treaty ratified in 1967 by the US, USSR, and UK.

“Article IX: … States Parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extra-terrestrial matter and, where necessary, shall adopt appropriate measures for this purpose.”

Requirements for Protecting Life on Other Bodies

Planetary protection prerequisites for each mission and interplanetary body in focus are ascertained based on the scientific advice of the Space Studies Board, NASA or international policy guidelines.

Each mission is categorized according to:

• Type of mission (e.g. flyby, orbiter, or lander)
• Nature of its destination (e.g. a planet, moon, comet, or asteroid)
• And the planetary bodies that may be discovered over the course of the mission (e.g. Mars and Europa).

Proposal to Increase Time-Scale for Planetary Protection

In the case of  Europa, the majority opinion was, that not only should Europa be kept it is not contamination-free during current times of exploration, but that it could well be scientifically important enough to warrant being kept in an un-touched and un-contaminated condition for future generations to benefit from studying too. 

“One consequence of this view is that Europa must be protected from contamination for an open-ended period, until it can be demonstrated that no ocean exists or that no organisms are present. Thus, we need to be concerned that over a time scale on the order of 10 million to 100 million years (an approximate age for the surface of Europa), any contaminating material is likely to be carried into the deep ice crust or into the underlying ocean.” 

(The minority opinion was that these protection measures are unnecessarily strong.)

But What About the Natives??!!

It is natural that we should want to explore worlds with the potential for life, and even to exploit them, but what if these worlds, such as Europa, do prove to have natives? There are different views on this subject. For example:

• If the life is only microbial then there is no cause to worry about it. We should not let microbes interfere with potential colonisation.
• It has its own ecosystem, and this should be left alone. However, if the long-term aim was to terraform Europa it would change the climate of the moon along with the rest of Europa.

Will we as egotistical humans decide, that despite knowing that this is a world that we have had no hand in creating, none-the-less that we should take measures to change it anyway? Or will we recognise our boundaries and appreciate that we have a unique standing in the cosmos, and therefore put aside our arrogance and leave untouched, a world, and possibly an eco-system, that we have had no hand in creating?

Europa’s Icewolf’s Personal Howl!

My personal howl on this subject is that absolutely Europa needs to be protected from Earth contamination! We do not know the consequences of any potential contamination. And precautions should be taken so that accurate observations can be made regarding any life found on Europa. If we find life there, it will have its own ecosystem and we should leave it alone and allow it to be a nature reserve moon. We may even be able to find ways to improve its habitat to help its life to thrive in ways not yet possible for it on icy Europa. It may be possible to ring fence the inhabited areas to reduce human contact, but it seems to me that such action would serve only to damage Europa, and ultimately this moon needs to be left alone! 

As mentioned earlier, backward contamination by micro-organisms (e.g. bacteria, certain algae and fungi) from other worlds are also a risk, when carried back to Earth on probes. which could have catastrophic upshots for Earth dwellers. Our immune systems will not have any resistance to extra-terrestrial micro-organisms. Not only would our bodies be totally unable to fight them it is pretty much guaranteed that we would have no time and no opportunity to research the creation of the necessary vaccine. Therefore, it will be essential to have high-level, cutting-edge systems for filtering and highly advanced procedures in place.

What do YOU think?!!

Discovering beyond all doubt that alien life does exist would have big impacts on Earth.

• Inevitably there would be changes to terrestrial science, technology, religion, politics and ecosystems as a result of contact with extra-terrestrial life, whether it be microbial or a technologically advanced civilisation.

Consequences for Society and Cultural Back-Lashes

Nobody will avoid the impact from the culture shock that would occur if we were to discover extra-terrestrial life, whatever form it might take. We would be forced to face the sudden reality that we were not a unique exception in the universe, which could cause a very serious back-lash in society as we know it. A culture shock of this nature could last for decades, possibly centuries. It would not only be ourselves affected in the deepest and most profound of ways but also our children and our children’s children. As we reach out to new, unexplored worlds with no real knowledge of what we might find there, exactly how the potential revelation of extra-terrestrial life and the impact on future generations is an issue that requires our consideration…

Europa’s Icewolf is Going to Mars!!

Mars-InSight Boarding Pass 🙂

My name is onboard the “passenger list” for the next mission to Mars-InSight!

InSight will launch in May, 2018. It will study the interior of Mars and listen for Marsquakes. 

Feel free to join me! I’ve recently completed an Open University course – How to Survive on Mars, so everyone will be fine! All my shiny new followers welcome too 🙂 It will be the perfect time to get to know each other…it takes a while to get to Mars! Look carefully, and you may even see the Black Wolves of Mars 😉

 

 

 

 

 

New evidence from NASA indicates that the most likely places to find life beyond Earth are Jupiter’s moon Europa or Saturn’s moon Enceladus. They, like Earth, are both ocean worlds and in both therein are some of the key ingredients for life.

A wealth of hydrogen molecules in water plumes soaring from the ruptures in Enceladus’s icy surface, have been detected by the Cassini spacecraft. The vital chemical methane, could also be establishing itself in the ocean beneath the ice.

The elusive presence of a water plume erupting on the warmest part of Europa’s icy surface, which has a salty liquid ocean beneath it was shown by the Hubble Space Telescope. The ocean itself contains double the amount of water found in the oceans of Earth.

 

Europa could be the pick of the bunch for life-bearing within our own solar system outside of our homeworld. will launch In the 2020’s the Europa Clipper will be launched, and should arrive at Europa a few years later. It will be the first to explore an alien ocean and will also fly through the plume to collect data.

It will definitely be a first to discover Intergalactic Liver Cake – staple diet of Icewolves, and indeed most domestic canines Earth! The structure of the Liver Cake may differ slightly from much-loved Earthly treat, but the Europan version is just as mouthwatering and tasty to both lupine and canine alike 🙂 And what better time than Easter, the time of ressurection and new life, to discover tantsalising new life hopes on worlds not so very far from home?

 

 

 

 

 

 

Icewolf of course, did not go hunting any down without telling Clowie, the Pyrenean Mountain Dog…she would never dream of such indiscretion 😉 …. Never!

Historic Potentially Earth-Like World Proxima B

The historic discovery of potentially Earth- like world Proxima-b was announced 24 August 2016. Orbiting Proxima Centauri, a Red Dwarf star in the habitable zone and the nearest star to our own Sun Proxima-b marks not only the closest alien planet ever found but also with the potential to be habitable.

This artist’s impression shows what the sky might look like on Proxima Centauri b if the planet has a surface. The exoplanet orbits the red dwarf star Proxima Centauri, currently the closest star to the solar system at 4.2 light-years. The other two members of the Alpha Centauri triple, Alpha Centauri A and B, would appear in the sky, too.

If this proves to be the case, then there is no shortage of time for some form of life to originate based on the fact that red dwarf stars such as Proxima Centauri burn for trillions of years.

From the point of view of the average Earth-based visitor stopping by for a summer vacation, Proxima-b runs the risk of being a rather boring holiday resort. The sun-tan would be awesome, not so much so the destruction of the biological cells exposed to the intensely dodgy UV radiation that is present. Combined with the prospect of heavy duty sun-screen to protect from the sun’s constant bombardment of energy flares bouncing around the planetary surface probably wouldn’t be classed as entirely awesome either. On top of which the Proxima Centauri flares would also banish any hope of using mobile phones, tablets, X-boxes or any other such devices thanks to its electronics-disabling qualities. so no ET calling home and definitely no Skype!

Although it is a tidally locked planet– roasting hot on its star- facing side, freezing cold on the other, there is also enough wind around in the atmosphere to circulate the heat, balancing out the extreme temperatures that would otherwise exist. None-the-less a visit to the the planetary darkside, where it is bathed in perpetual night could prove to be the safest, and possibly the only option.

 

 

 

 

 

 

 

 

 

Unfortunately astronomers are choosing to be particularly pessimistic about this little world following the initial euphoria and have currently decided it is probably a dead, airless rock that will never harbour life due to it’s close proximity sun (20x nearer than Earth to the Sun) creating a risk of it boiling off the water and thereby stripping away the planet’s atmosphere. Researchers its oxygen will be gone in about 10 million years. Life on Earth took billions of years to develop.

However hope lives eternal. Theoretically it is possible life could advance to endure the high levels of radiation, by altering the worst of Proxima Centauri’s emissions into inoffensive visible light. We know this is plausible, because due to a process known as biofluorescence this —has already happened on many occasions on Earth.

 

 

 

 

 

Ultimately It is expected that the 2018 launch of The James Webb Space Telescope, will provide answers to the critical question of whether there is any chance at all that Proxima b is capable of supporting life.

Proxima b – Habitable ‘Ocean Planet’??

Another possibility is the Proxima b could be an ocean world whose entire surface consists of a liquid ocean. This may bear a similarity to the Jupiter and Saturn moons that are icy worlds with subsurface oceans.

On the other hand the more optimistic researchers suggest that Proxima b may in fact be habitable after all. So don’t put the suitcases back in the attic just yet intrepid cosmic holiday makers! If Proxima b had in reality formed further out from it’s sun than its current position this would also offer a high possibility of there being water. This idea is based on the outer realms of planetary systems being more likely to form ice. If it then moved inwards for a up closer and more personal relationship with its sun then this ice could melt and form seas. Maybe 😉

Proxima b – A Desert World??

But it still seems most likely, according to Victoria Meadows (University of Washington), that this exoplanet is a desert world since the radiation bombarding it would almost certainly have evaporated the majority of the water. This process could have collected the oxygen and hydrogen in the water and created an atmosphere rich in oxygen. Then again it could a 2^nd Venus with an atmosphere rich in Carbon Dioxide, or even another Uranus or Neptune.

The Other Closest Habitable-Zone Worlds

If all else fails cosmic holiday makers may wish to try some of the nearby, potentially habitable exoplanet worlds, for size….: Kapteyn b (13 light-years away) and Wolf 1061 c (14 light-years). Both planets are just over half again as wide as Earth, with minimum masses of 4 to 5 Earths, and both are in their stars’ habitable zones. Wolf 1061 c does not look at all hopeful in terms of habitability. But Kapteyn b looks good. It’s about 3½ times farther from its sun than Proxima b is from its sun so potentially it could be far enough out of reach of its sun’s rather violent output to provide a half decent holiday resort!

What Would it Be Like to Live on Earth’s Cousin?

The discovery of Kelper 452b was announced on 23/05/15, and is 1,400 Light years away.

An alien experience!

Exoplanet Kelper 452-b is 60% wider than Earth and approximately 5x as massive so much stronger surface gravity.

This provides for a great workout! For the manly among us this essentially means it will make you much stronger 🙂

For everybody chilling on this Earth cousin, the higher gravity would probably lead to significant body changes long term – e.g. becoming stockier built. This is probably not a plus if you’re already on the stocky side…you may become very short and squat…like a rotund garden gnome 😉

 

A Familiar Experience

As this world’s sun is roughly the same distance away as on Earth, the light factor would be much the same as on our home-world and Earth plants transported to its cousin-world could photosynthesis the same as on Earth.

 

 

 

 

 

So Kelper 452-b is similar to Earth but not the same. Its sun is 6 billion years old whereas our Sun is only 4.5 billion years old. Kelper 452-b’s sun is at a far more energetic life-stage therefore it is hotter. And it is about 10% larger and 20% brighter in the sky. Not bad for the sun tan then 😉

Kelper 452-b completes one orbit every 385 days so it’s year is only about 20 days longer than Earth’s. Pretty much home from home.

The Gemstones of Mars

Precious gems are not exactly what you would expect to find on Mars. The “Compact Reconnaissance Imaging Spectrometer for Mars,” CRISM, for short, is a nifty device that has already found indications of water on Mars; a pretty cool move in itself, using a technique known by the fancy title of “reflectance spectroscopy” which allows it to "see" minerals on the Martian surface.

Not satisfied with just being a smart Imaging Spectrometer it goes one step further and on occasion becomes super-smart and really shows off detecting gemstone. The pretty picture below is a Martian crater’s central peak, the vari-coloured area representing minerals, whilst the pretty pink areas represent concentrated hydrated silica better what is known on Earth as Opal.

CRISM Finds Opal in a Martian Crater:  NASA/JPL/JHUAPL

Opal is a really cool discovery. One reason is that opal often has high water content. And on Earth opals often contain preserved fossils and other signs of biology consequently it could potentially preserve the history of life on Mars. Martian Opal is also more valuable than the most precious diamond shining brightly in the sol light of Earth. Collect a handful and you could be an incredibly rich Earth dweller!

Opal is the birthstone for October, so what better place to go for your birthday treat than Opal hunting on Mars? Who knows how many of these precious and beautiful gemstones are lying in wait for you birthday babes in the Craters of Mars just waiting for you budding October opal babes to flash your geologists hammer to expose these glimmering gemstone treasures in the shimmering Martian sun.

Silence in the Shadows ~ 3

 

“Where are you going??!!”  She eyed him appraisingly apparently unfazed. “You’re going back to the zone??”  He glared at her as if she had grown two heads. “And how exactly do you expect to get past the check points?!”

“They’ll never know…” she smiled secretively, confident…and in a shimmer of moulton fire she became before his eyes something else… He started, muttering a string of expletives. A glowing black-gold star wolf stood before him in her place, tail wagging gently, head lowered, watching him. When she spoke again it was silently, in his mind – telepathy. “The wolf is more tolerant of the radiation. …if the levels increase and the risks become too great I’ll turn back…” (Silence in the Shadows ~ 2)

Night on an alien world

Liquid night moved fluidly in its telepathic touch reaching out with the diversity of a thousand worlds – worlds that lay far beyond the stars – probing, touching in a subtle quest for the tundra of secrets beneath the carefully layered protection of dark and light, blending in the alien moon touch.

Dark shadows raced across the darkened tundra of the exclusion zone plains skating across a rock strewn terrain.

Twin satellites – huge and radiant, hung silently in the star scope beyond; their shivering iridescence dancing and playing in an alien night, casting slivers of satellite suns chasing ghost-like across a cratered planetscape.

Night on an alien world

 

Shimmering in the diamond-kissed emissions of the zone’s twin satellites, and bathed in an other-worldly glow, the devastated N-reactor plant structure stood sentinel to the visiting Sirian she-wolf flitting wraith-like amongst the toxic, stellar structures, elongated shadows sliding smoothly into the soundless tranquillity of the void.

 

Yelena was alone other than the ever present zone wolves flickering in and out of eerie rock formations beyond the irradiated deadlands. Alone, whilst the light of a thousand worlds burned down in remote, icy indifference-brilliant and piercing in a cool, exotic night. And a glittering myriad of new constellations teased an unearthly light into pirouetting effortlessly across an unfamiliar planetscape.

 

The radiation count was high here. Yelena could taste it in the air, her coat and skin prickly with its unseen presence, strands of alien wolf hair crackling in the radioactivity, darkening to smoke black in the monochromatic light of the zone’s twin satellites, the collar-mounted Geiger counter chirping frantically.

Mystical shrouded structures rose up like vaguely menacing spectres in the dark regions of the starry arrays that were her world. She was beautiful. Yet it was a barren beauty, remote and forsaken in this unnatural radio-active Land of Wolves.

Night in an alien exclusion zone.

Ears flicking, nose raised to catch the untold scents of the mysteries of the zone, Yelena strained to hear above and beyond the absolute silence infusing the shivering planetscape, timeless and disturbingly bereft of all sound other than the empty stirring of the wind. The beating heart of eternity cool and changeless and the ominous chitter of the Geiger counter, a constant reminder that all was far from well in this contaminated land.

Night shone down on the foreboding sentinel of the toxic reactor skeletising the gaunt structures and embracing the cool, concrete bases. Sudden spectral light slid uneasily through the exposed reactor cores throwing sinister and outlandish shadows chasing across insubstantial stadia into the critically contaminated lands that lay beyond.

            

Caught in dazzling primeval shards restless Zone Wolves glimmered in sudden cloud-cleared lunar arrays, setting alight the frothy, and platinum-frost coat-overlay characteristic of the packs of radio-active N-wolves that roamed wary and shadowlike within the hostile environs of the exclusion zone.

Hunting in the Land of Wolves.

 

Yelena watched silently shielded by the haunting sentinels and alien crags, rock faces, dusted with layers of dark and radio-active regolith. The aloof glitter of distant stars abnormally bright in the clear skies. Eclipsing pools of lunar light sinking without a sound into the mystery of veiled, astrophysical musings, catching briefly, the remote, rippling beams in fluid star black eyes. Dark shadows played across her eyes fire sparking across her fine boned muzzle in layers of dark chocolate and golden sunsets.

Night in an alien exclusion zone.

 

A wretched undulating wind eddied amongst the structures echoing inconsolably with tales of another time and place. It lifted Yelena’s soft black-ash fur touching her mind and spirit with the mournful sound of its desolate keening, till she too flung back dark, silken head and howled. A chilling, sound that evoked the devastating sense of loss and anguish of those abandoned or who had chosen to linger a little too long – lost to the Land of Wolves. Discharging the tortured suffering of the land, the catastrophic heartbreak and the numbing despair; its contamination and its abandonment and the dying ghost towns left in its wake; the tragic, soul-destroying song of the stars as the dark, stricken she-wolf called her grief to the interstellar void. A distant, unfeeling void…

Howling in the land of Wolves.

His passage was confident… deliberate… His advance a single, measured move calculated to block any further headway -The exclusion zone Alpha Male, polished starlight glinting off his radio-active form. Powerful and not of her world, claiming not only leadership of the pack but demanding also mating rights to the visiting alien she-wolf. Defiant She-wolf! … Yelena bared glistening teeth at him both in stark momentary warning and also quick sun-flamed invitation as she sought comfort in the zone wolves Alpha under the light of another star…..

      

She-wolf! Night Caller!

Liquid night moved fluidly in its telepathic touch reaching out with the diversity of a thousand worlds – worlds that lay far beyond the stars – probing, touching in a subtle quest for the tundra of secrets beneath the carefully layered protection of dark and light, blending in the alien moon touch.
