Planetary protection refers to âinterplanetary contaminationâ – protecting solar system bodies (i.e., planets, moons, comets, and asteroids) from âbiological contaminationâ by Earth organisms, (Forward contamination – the transfer ofâŻâviableâŻorganismsâ from Earth to another interplanetary body), and protecting Earth from the transmission ofâŻalienâŻorganisms, to Earth’sâŻbiosphere e.g. as a result of âextra-terrestrial sample-return missions.â (Back contamination)
Planetary protection is a directive code in the blueprint of an interplanetary assignment, and is critical for several important reasons: Â
The legal basis for planetary protection is located in Article IX of the United NationsâŻOuter 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.”
Planetary protectionâŻprerequisitesâŻfor each mission and interplanetary body in focus are ascertained based on the scientific advice of the Space Studies Board,âŻNASAâŻor international policy guidelines.
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.Â
“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.”Â
(The minority opinion was that these protection measures are unnecessarily strong.)
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:
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?
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!Â
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.
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…

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.Â
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 đ 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 đ
New evidence from NASA indicates that the most likely places to find life beyond Earth are Jupiterâs moon Europa or Saturnâs 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 Enceladusâs 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 Europaâs 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 2020âs 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 đ 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 đ …. Never!

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.
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 sunâs constant bombardment of energy flares bouncing around the planetary surface probably wouldnât 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 planetâ 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 itâs close proximity sun (20x nearer than Earth to the Sun) creating a risk of it boiling off the water and thereby stripping away the planetâs 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 Centauriâs emissions into inoffensive visible light. We know this is plausible, because due to a process known as biofluorescence this âhas 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.
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 donât put the suitcases back in the attic just yet intrepid cosmic holiday makers! If Proxima b had in reality formed further out from itâs 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 đ
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 2nd Venus with an atmosphere rich in Carbon Dioxide, or even another Uranus or Neptune.
If all else fails cosmic holiday makers may wish to try some of the nearby
, potentially habitable exoplanet worlds, for sizeâŠ.: 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 starsâ habitable zones. Wolf 1061 c does not look at all hopeful in terms of habitability. But Kapteyn b looks good. Itâs about 3Âœ times farther from its sun than Proxima b is from its sun so potentially it could be far enough out of reach of its sunâs rather violent output to provide a half decent holiday resort!

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 đ
For everybody chilling on this Earth cousin, the higher gravity would probably lead to significant body changes long term â e.g. becoming stockier built. This is probably not a plus if youâre already on the stocky sideâŠyou may become very short and squatâŠlike a rotund garden gnome đ
As this worldâs 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-bâs 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 đ
Kelper 452-b completes one orbit every 385 days so itâs year is only about 20 days longer than Earthâs. Pretty much home from home.

The Gemstones of Mars
Precious gems are not exactly what you would expect to find on Mars. The âCompact Reconnaissance Imaging Spectrometer for Mars,â 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 âreflectance spectroscopyâ 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.
Read more about CRISM on a new web site dedicated to the instrument and its discoveries on Mars.
