Ceres, Dawn, Pyramids & Craters


NASA’s spacecraft Dawn has been on a mission to the planet Ceres which is located between the orbits of Mars and Jupiter. Compared to Earth’s diameter of almost 8,000 miles, Ceres seems tiny with a diameter of less than 600 miles. It is so small that despite its official designation as a minor-planet, there are still those who will call it an asteroid or a dwarf planet. To put it in perspective, the entire surface of Ceres is about the same size as India or Argentina. Whatever the moniker, the dear reader gets the point. Still, UFO and ET enthusiasts like to believe that Ceres was once home to an intelligent otherworldly species that liked to build pyramids. The gringa can only say, “Um, not.”

Why is the gringa so sure of herself in raining on their parade? Let’s take a look at some of the geographical and geological characteristics of this teensy-weensy little world:

Craters

First of all, just take an up close and personal look at the pitiful pitted little thing. It has more impact craters than an eight-year-old ginger gringa had freckles. It seems pretty obvious to me that with global environmental disasters happening on a regular basis, it is very unlikely that life would flourish in such a place. Not to mention any surviving life having the opportunity to pursue advancements.

Elements

Ceres, in many ways, is pretty much a clone of our desolate moon, an enormous rock with a lot of ice. With no evidence or traces of ever having vegetation, any ETs most assuredly would have starved to death. Unless, of course, it was a civilization that could survive on the nourishment of clay seasoned with ammonia and a splash of salt and iron.

Environment

It’s highly unlikely that water as we Earthlings know it ever existed on Ceres. Although there is alot of ice, enough even to indicate the possibility of an ocean at one time, it wouldn’t have been a salty brine like we are accustomed to, inhabited with sharks and whales and penguins and such. It most likely would have been a caustic sea of ammonia and sulfuric acid. So, unless those ETs had skin of steel and enjoyed a dip in antifreeze, any recreational activities of a Ceres civilization would have been strictly limited to land-lubbing.

Details, Details, Details

If the gringa has sufficiently convinced you that no one was building pyramids on Ceres way back when, let us move on to the details that are still interesting despite lacking any ET spin.

In the late 1700s Johann Elert Bode suspected a planet existed between Mars and Jupiter. However, the official discovery of Ceres is credited to Giuseppe Piazzi in 1801 who first claimed it was a comet. It was later classified as a planet but then redesignated as an asteroid in the 1850s. It seems scientists still haven’t made up their minds because it can be called any number of names when referred to by different people. The gringa doesn’t so much care. It makes no difference to me. Ceres is just Ceres, a planet named after the Roman goddess of agriculture despite the fact that not a single ear of corn or blade of grass has ever been grown on its surface.

Over thousands of years meteors and comets have slammed into Ceres, creating hundreds of craters. A few of them are distinctly bright, containing either minerals with reflective properties or light reflecting off of ice. It is theorized that underneath the crusty and dusty surface of Ceres is a layer of water and ice that, by volume, is more than the fresh water found on Earth. This has led to scientists entertaining the notion that if living organisms once lived in the sea of Ceres, it is possible that through the many cosmic impacts throughout history some biological material may have been ejected into space and made its way to Earth. So, ETs on Ceres? The gringa thinks not. ETs from Ceres on Earth? It’s possible.

Viewing

Ceres is too dim to be seen with the naked eye except on extremely dark sky conditions. The best way to peek at Ceres is through a pair of binoculars or a telescope. The best time to see Ceres is fast approaching, from August through April. Observers in mid northern latitudes should look toward the low southern sky after nightfall. It is best to view on a night when the Moon is in waning stages. Look toward the Sagittarius constellation and Ceres will arc slowly westward and approach the border of the Capricorn constellation.

If you have a fancy telescope you can enter coordinates and the telescope will do the hard work of locating and tracking for you. But if you only have binoculars, it is still easy enough to locate and track Ceres so don’t be discouraged.   For some help in finding Ceres, online astronomy clubs are a great resource.  The gringa wishes you the greatest success in taking a peek at Ceres!

Cosmic Spas & Outer Space Mineral Mines


Are NASA and other international space agencies interested in creating colonies on the Moon and various other exotic, cosmic locales? Most certainly. However, not for the nefarious purposes of whisking away the highly educated and financial elite in order to preserve the human race from extinction. What they really want to do is exploit the natural resources of these places.

Humans are a hungry species and their appetites include all sorts of stuff from fruits and vegetables to minerals and ores. Many minerals and ores are not only rare, with few deposits in sundry places around the world, but are also finite in their supply. Once diminished, humans will have to find another source. That’s where asteroids and the Moon come into play.

Asteroids are like one of those grab bags you get as a party favor. You never know what’s inside. Although primarily chunks of ice, tar and dust, they also contain scare minerals and metals. For astronaut mining crews, outer space is full of opportunity, kind of like a mechanic entering an auto junkyard the size of Earth. Best estimates to date believe there are hundreds of thousands of asteroids, some nearly five billion years old, of assorted sizes and shapes from the size of a coffee table to hundreds of miles in diameter (Earth, in comparison, is about 8,000 miles in diameter). With such abundance, if humans can overcome the technological and economical obstacles, we may have a seemingly limitless supply of raw materials available.

The gringa wonders what will happen when that occurs? Will space become filled with flag waving asteroids? Considering even a small asteroid could be valued at many millions of dollars in potential minerals, will countries be zipping about space, hither and yon, planting flags on as many asteroids as possible in a territory game of, “Mine! I found it first!”? The gringa is hoping it will be much more civilized than that.

For mining purposes, asteroid’s are classified according to three groups based on light reflection (spectral) analysis. Since mankind cannot yet land on an asteroid and physically take a geological sample or do so with a robotic satellite, scientists evaluate how light reflects off the surface of an asteroid to determine its primary mineral component.

C-type asteroids are dark and carbon based. They are comprised of clay based minerals that have lots of water trapped within the clay. The gringa thinks these could, perhaps become cosmic spas if we could find a way to generate some kind of thermal reaction within the asteroid. Think of it, “Come visit asteroid XP-247 for its relaxing steam baths and mineralized clay body and facial wraps. Just don’t forget your oxygen mask.”

But what about the carbon and other stuff in the clay? Is that any good for anything? Yep. It makes a garden grow lush, thick and plentiful. C-type asteroids rich in carbon, phosphorous and other elements in the fertilizer spectrum could be very valuable as future garden spots. The gringa can now see the cosmic version of the “Hanging Gardens of Babylon” where visitors can also get a soak in the hot springs and a beautifying and detoxifying mineral rich clay body wrap.

I mean, really, we have plenty of clay and carbon and water here on Earth but surely there will be an eager entrepreneur who will see the same potential. Or do we really have plenty of clay, minerals and water on Earth?

The water reserves could very well come in handy. The gringa can see it now – a gravity beam lassos a water rich C-type asteroid and hauls it near Earth’s atmosphere. It then uses transporter technology that has finally been perfected to zap it through the atmosphere, avoiding a friction filled entry that would evaporate up all that precious water. Then, as it approaches fatefully close to a desert region, just before impact a precision laser beam goes, “ZIP, ZAP, ZOOM!” and a lovely shower of water rains down upon the desert with all the pulverized clay and carbon providing rich fertilizer. The desert is soon a fertile oasis. Hey, it could happen. Stranger things already have.

But NASA thinks the real value of water rich asteroids is in using the resource in outer space. By finding a way to mine the water in flight, crews could save billions of dollars by not having to pack this life-support necessity. Interestingly enough, the very thing that humans need to survive, consisting of two molecules of hydrogen and one of oxygen, are the very elements of rocket fuel. (Wow, humans are 60% rocket fuel, or, water, depending on your perspective!). So, astronauts dock their spaceship at a galactic version of Exxon to fill up the tank and top off the water reserves. And while the service station is checking the engine’s oil level and cabin’s air pressure, the crew is freshening up at the nearby spa. Interesting.

So, C-type asteroids can either be Desert-to-Eden conversion sources, hot spring spas, water wells, or rocket fuel depots. Or all three at the same time.Take your pick.

S-type asteroids shine a little brighter than dark, carbon based C-types. That’s because they are rich in reflective metals like cobalt, iron and nickel. If a mining crew is really lucky they could find one with deposits of rhodium, platinum or gold. Scientists estimate that an asteroid about the size of an average bedroom could be packed with well over one million pounds of metals, a tiny fraction being the exceedingly valuable rare ones. Even if mining crews could extract just one hundred pounds of platinum, at about $1000 an ounce, a $100,000 load of platinum would just be the gravy on top of the wealth accumulated from the remaining predominant minerals.

But it may be the M-class asteroids that wars end up being fought over. The wars for oil that we have raging now could very well become wars for M-class asteroids in the future. These asteroids are expected to contain at least ten times the mineral content of S-types.

To make space mining a reality, the mission has to be profitable. With current missions costing in the hundreds of millions, some even billions, an asteroid would have to be massively rich in raw materials. The other option is to develop technologies that are more economical.

Before any of that even matters, current asteroid knowledge needs to be vastly broadened and fine-tuned. We need cosmic cartographers to accurately map the hundreds of thousands of asteroids in outer space. The world needs space geologists that have the technology and knowledge to analyze what minerals each asteroid actually contains. Young students now, who have an interest in a cosmic career, could really have a geology or cartography degree pay off by landing them their dream job.

NASA’s first effort to test their scientific mettle for determining present mineral resources within an asteroid lie with their OSIRIS-REx mission. The goal of “Origins, Spectral Interpretation, Resource Identification, Security and Regolith Explorer” is to return with a geological sample from asteroid Bennu. It is set to launch in September and arrive at the asteroid almost two years later. If all goes according to plan, Earthlings can expect an authentic piece of Bennu to arrive on planet Earth around 2020. (Of course, the gringa is reminded of her favorite piece of motherly advice given regularly to her children in efforts to cultivate a more relaxed approach to life, “The plan is that nothing goes according to plan.”)

In addition to geological studies of Bennu’s raw materials, asteroid re-direction technologies will also be studied. The spacecraft is scheduled to perform an interesting experiment. It is going to give Bennu a gentle, solar nudge. Scientists want to know if sunlight can be used to affect the path of travel of asteroids. I guess the reasoning is that asteroids are too valuable to simply blast into oblivion if Earth happens to be in the way. They would rather nudge them aside then attempt to exploit the wealth they contain.

The most important goals of the mission, however, are to further the development of space mining technologies. They plan to scrape together a two ounce and 4.4 pound geological sample. The spacecraft will then use its state-of-the-art instruments to map the surface of Bennu and analyze its composition. These are the on-board technologies and their purposes:

  • OVIRS (OSIRIS-REx Visible and Infrared Spectrometer) – analyzes visible and near-infrared light to detect minerals, compounds and chemicals within the asteroid.
  • OTES (OSIRIS-REx Thermal Emission Spectrometer) – analyzes infrared light to detect surface minerals of Bennu, determine surface temperature and map the location of water-rich clay mineral deposits.
  • REx (Regolith X-ray Imaging Spectrometer) – analyzes X-ray aura of Bennu’s surface in sunlight to calculate amounts and locations of elements like: iron, magnesium, silicon and sulfur.

To find out if sunlight can be used as an asteroid diversion technique OVIRS and OTES will combine their abilities to study what is known as the “Yarkovsky effect”. When an asteroid absorbs sunlight much of the heat radiates outward and provides a propelling effect. Observations will be made to see if a “man-made” solar heat saturation could result in changing an asteroid’s trajectory.

Most of what will be recorded by the different spectrometers will only reflect what is on Bennu’s surface and within a shallow depth (about half a millimeter). They are not capable of reaching deep within the asteroid’s core. To get a deeper look the spacecraft has a tool that blows nitrogen gas onto the surface that will force minerals up from a depth of about two inches. Even so, it’s pretty obvious that much about Bennu will remain unknown even if the mission is successful in achieving all of its goals.

But, a successful mission will at least tell the world one thing: can mining asteroid’s work? The gringa believes if great wealth is at stake there will be movers and shakers in this world who will make it work one way or another while pocketing a healthy profit in the process.

Operation Highjump – Not The Launch of a Dark Ops Space Program


Certain conspiracy theorists (CTs) have put forth that there is a dark ops space program called Dark Fleet that is an offshoot of technology and goals that originated with secret societies that organized during the heyday of Nazi Germany. The members of these organizations were not so much devoted Nazis but, rather, exploited the resources and power of the Nazi party in order to realize their fantastical dream of reuniting with a superpower, extra-terrestrial, master race.

After the Nazi empire crumbled when they lost World War II, many of the members of the secret societies relocated to other countries and kept their dreams and research alive, supposedly developing advanced weapons and spacecraft technology. As proof, CTs offer up the records of Admiral Byrd’s expeditions to the North and South Poles. The gringa says, “Well, let’s take a look at those records.”

There is a wealth of information about Admiral Byrd but the gringa wants to stick with facts and eyewitness accounts. To begin with, a look at official military records. Is there anything interesting there? Hmmm. Let us see…

From 1946-1947 the U.S. Navy had Operation Highjump underway. This operation was overseen by the U.S. Navy Antarctic Developments Program. Rear Admiral Richard E. Byrd, Jr. was Officer in Charge, leading Task Force 68, and Rear Admiral Richard H. Cruzen was commanding officer. When these two admirals put to sea, they were joined by 4,700 seamen and airmen, 13 military ships, and 33 military aircraft. To achieve the goal of establishing a research base, Little America IV, it sounds like an awful lot of firepower was put into play, but, that’s just the gringa’s curious little mind in overdrive. It could have been perfectly normal to pack all that weaponry on an Antarctic excursion.

The published objectives of the mission were:

  • Personnel training and equipment testing in subzero temperatures
  • Evaluate how to establish, maintain and utilize Antarctic military bases and scout sites
  • Develop techniques for creating, maintaining and using military bases in ice
  • Make new discoveries of the following Antarctic conditions: electromagnetics, geological, geographic, hydrographic, and meteorological

Up until this time it was primarily the British who had spent time exploring Antarctica with eleven expeditions from 1898-1945. Other countries who had explored the earth’s South Pole region: France (2 missions); Germany (3) missions; Belgium, Japan, Norway, and Sweden (all a single mission). Operation High Jump was the second U.S. mission, following the conclusion of Byrd’s initial exploratory expedition four years earlier.

The fleet of ships arrived in the Antarctic December 12, 1946 and immediately set up weather monitoring stations. Within 12 days of arrival aircraft was in the air flying reconnaissance missions. Some of the ships that were in the flotilla:

  • Henderson – Destroyer class, commissioned in 1945 and served with distinction for 35 years receiving (8) battle stars for service in the Korean War and (7) battle stars and a commendation for service in the Vietnam War; armament at the time of Operation Highjump: (6) 5” guns, (12) 40mm anti-aircraft (AA) guns; (11) 20mm AA guns; (10) 21” torpedo tubes
  • Cacapon – Cimarron class fleet oiler; commissioned 1943, decommissioned 1973 and scrapped; armament: (1) 5” gun; (4) 3” guns; (4) twin 40mm AA guns; (4) twin 20mm AA guns
  • Currituck – Currituck class seaplane tender, nicknamed “Wild Goose”; commissioned June 1944, decommissioned October 31 1967, scrapped 1971; armament: (4) 5” guns

Eighteen days after arrival (3) men were killed when their plane crashed during a blizzard. Six crewmen survived the crash and were rescued two weeks later. The remains of the plane and the three lost airmen have never been recovered. The aircraft they were flying was a Martin PBM Mariner. This craft is a patrol bomber flying boat. Standard armament for the Mariners were: (8) 50” machine guns, 2 tons of bombs or depth charges or (2) Mark 13 torpedoes. The gringa can only ask why a bomber would be needed in an exploratory, scientific expedition in Antarctica?

An interesting thing to note is that there was a Navy chaplain serving on the mission. He held a religious service and consecrated Antarctica. The gringa scratches her head and wonders if this is typical or strange? I’m no Catholic so I wouldn’t know.

New Year’s Day, 1947, American dive team began exploring underneath Antarctic ice shelves. The gringa supposes this may have been related to search efforts to locate the downed bomber. No big mystery there.

Two weeks later an airfield was constructed and named “Little America IV”. Within a month, late February, weather conditions worsened and the expedition was terminated. The return trip home would have the expedition making a stop in March along the South American coast. Admiral Byrd gave interviews and a Chilean newspaper, El Mercurio, reported. The most interesting quote the gringa will share is often cited by CTs to prove that something dark was afoot underneath the ice:

“… Byrd warned today that the United States should adopt measures of protection against the possibility of an invasion of the country by hostile planes coming from the polar regions.”

Now, was Byrd’s warning because he thought something sinister was going on secretly at either the North or South Pole? No. That’s not what his warning was about. CTs take that important quote out of context. They don’t usually reveal the rest of the interview which explains Byrd’s reasoning.

He recognized that technology meant the world was shrinking. America was no longer safe from enemy invasion because of isolation and distance. It was well within the capabilities of other nations to fly from one side of the globe, passing over either pole, and reach the U.S. Byrd was not fearful of a threat from an extra-terrestrial master race living within the earth and Antarctica being its headquarters.

So why all the firepower on an exploratory mission? It was right after World War II. The U.S. had already experienced the surprise air assault of Pearl Harbor. The militaries of the Allied Powers knew that Germany had been developing new weapons and technologies. The Navy had no idea what to expect and was taking no chances. The gringa says, “I don’t blame them.” So, no big suspicious, nefarious plot behind packing all the big guns on an expedition to Antarctica.

Just a few of the vessels that comprised the fleet’s complement:

  • Sikorsky R-4 helicopter
  • (2) Coastguard icebreakers
  • US Navy icebreaker
  • (2) Seaplane Tenders
  • (2) Destroyers
  • (2) Tankers
  • Battleship
  • (2) Supply ships
  • Submarine
  • Aircraft carrier (Byrd’s ship)

The gringa thinks that the main reason behind U.S. interest in Antarctica at that time is the same ol’, same ol’ imperialistic territory seeking mentality that has motivated the country’s interest throughout history. Great Britain had spent a lot of time in Antarctica. They also created all sorts of problems over the Falkland Islands. When the U.S. decided to stick their big nose in and establish a military base in Antarctica most of Latin America was none too happy about it.

The Cold War was getting under way and Russia was perfectly suited to wage war in the bitter conditions of a European winter. Americans? Not so much. So, according to official records the expedition to Antarctica was absolutely about military strategy. Not about little green men living under the ice. But, then, there’s Admiral Byrd’s personal diaries. What do they say? Well, come back and see what the gringa finds out!

A New Moon For A New Age


Most people think Earth’s moon is old news. However, what the public may not realize is that NASA has a rover active on the Moon, the Lunar Reconnaissance Orbiter Camera (LRO). The gringa will call the rover “Elroy” for your reading pleasure.

Elroy has a new exhibit on display at the National Air and Space Museum in Washington, D.C. that reveals that our Moon is anything but boring. What with Mars and black holes and parallel universes getting so much attention, it’s easy for our little ol’ Moon to get lost in the mix. The gringa wants to give it some glory that is long overdue.

One thing that is interesting about the Moon is that it undergoes such frequent change. It seems to get blasted all the time by meteors and such. The images on display in the exhibit show the formation of new impact craters (kind of scary when the gringa considers its proximity to home! The Moon may very well be our shield!). Recent volcanic activity has also been detected. And, most curious of all, is evidence that the Moon’s core may be cooling which has caused it to shrink and crack the crust of the Moon’s surface.

Elroy is a busy little rover. So busy, in fact, that there are too many images for this single exhibit. So, in addition to the favorites that were selected for display, there is a large screen which projects lunar images that are updated daily.

Since 2009, in addition to a fabulous photography collection, Elroy has also collected environmental and geological data with the seven other instruments he is equipped with. Elroy’s mission is to map the entire surface of the Moon. Even the legendary “dark side” of the Moon.

You see, one reason the Moon remains so mysterious is because it has a “backside”. Yes, we never get to see the Moon’s rear-end. We always see only one physical side of the Moon. Now, this is not because the Moon hangs suspended in space and never rotates. It’s just that it has a rather peculiar rotation cycle.

Millions of years ago the Moon spun around much faster. The pull of Earth’s gravity has caused it to slow down. So much so that its rotation cycle now matches its orbit cycle.  These cycles take 27.3 Earth days. However, observed from Earth it takes 29.5 days. (Don’t expect the gringa to get into that mystery here! You can research it yourself by clicking on… Understanding the moon phases). So, since the orbit and rotation cycles are exactly matched, as the Moon travels about the Earth, at night, when we see it, the same side is always presented to Earth.

However, for serious stargazers with top-notch telescopes, you can get a peek at a sliver of the hidden aspects of the Moon. Since the Moon is not “round and flat” like a coin but is actually elliptical, like a ball, at just the right time there is a speed differential when the Moon is farthest from Earth, thereby its rotation speeds up a bit because of a little less gravity drag. This causes what scientists call a “rocking” motion and an extra nine percent of the Moon’s surface is visible. But now, thanks to Elroy, all Earthlings can see just exactly what is on the Moon’s backside which is not “dark” after all, except during the cycle of a full moon when the Earth is blocking all sunlight.

Only two years into its mission NASA declared Elroy a complete success. Over four billion measurements were used by Elroy to complete a topographical map of the entire Moon. Elroy’s instruments determined that the coldest spot in our entire solar system is right smack on the Moon. It is found inside the shadows of Hermite crater which is located near the north pole. It is a bitter minus 415 degrees Fahrenheit. The gringa hopes Elroy was wearing his mittens.

Elroy is not just taking photos and temperature readings. The rover is also looking for water deposits, such as ice, and searching for fuel resources such as hydrogen. In preparation for future manned Moon missions, environmental radiation levels are also recorded.

So, the next time you gaze up at the Moon, give Elroy a salute. He is still on the job!

Moon or Mars?


The gringa has been down in the dumps, a bit, but, I will soon bounce back and become moon-eyed over what will have to become my new pet project. You see, after getting me all excited and pumped about getting to Mars, Congress has gone and rained all over my parade, the ol’ party poopers.

You see, Congress just doesn’t have what it takes to believe in a starry-eyed dream. NASA’s dreams Congress wants to shoot down:

  • Landing a human on an asteroid by 2025
  • Manned mission to Mars in the 2030s
  • 2nd manned mission on the Moon

Congress had a hearing on these subjects. The gringa can just hear all the discouraged “Tsk, Tsking” that must have gone one amongst all these “responsible” folk who know nothing about dreaming big. If the responsible purse-string holders don’t get more details on NASAs budgetary needs for these goals, then NASA may only get approval for the Moon mission.

Now, the gringa does not deny that these goals are not just ambitious but, to some, may sound downright outrageous. But, hey, the reality is that it is the outrageous dreamers that brought us the telephone, computer, car, steam engine, etc., etc.

It is also true that much of the technology necessary to survive a mission to Mars doesn’t even exist except in the minds of scientists and their scratched out theories on paper. But isn’t that the very first step? Aren’t these outrageous dreams what inspires innovative minds to try something that seems impossible and, finally, to accomplish it? Isn’t that the greatest way to create history?

I mean, if it wasn’t for the dream of traveling through space and solving the inherent problems of that goal we would have never come up with things like digital music, lasers, etc. Developing science and technology to solve space exploration problems is not wasted taxpayer money. There are all sorts of benefits to Earth and humans with spin off technologies.

Congress even hinted at an ultimatum: Mars or the ISS. The money is simply not there to do both. The idea is being tossed around to ditch Mars and concentrate on the ISS and returning to the Moon. Some see the development of a Moon base as an opportunity to exploit the mineral resources of the Moon.

Well, Congress may be packed with a bunch of Negative Nellie Republicans, but the gringa is proud that her president is encouraging all the dreams of NASA. Not only is President Obama openly encouraging a return to the Moon and the establishment of a Moon Base, but he hopes NASA stays on track to get to Mars in the 2030. I guess one positive of the liberal mindset of a Democrat is that they dream big and believe nothing is impossible to achieve!

Although Obama has been supportive throughout his two terms in office, his last term is coming to an end soon. NASA realizes the very real possibility of a government transition and a new president that might just nix the Mars mission altogether. They have been enjoying this dream being supported for almost eight years and now have to consider the possibility of a newcomer dooming it. The gringa thinks that not only would that be small-minded, but also just downright mean.

However, it may not be all that surprising if a new president expects the space agency to turn its focus Moonward rather than Marsward. After all, that is the focus of the ESA. Europe wants to establish a lunar orbit working colony that remotely controls Moon-bots that work below on the surface.

With all its focus on Mars, NASA has only considered the Moon in the sense of it being a waystation on the way to the Red Planet that is the real goal. This strategy may have to be reconsidered. It seems that the ESA is not alone in thinking the Moon to be the most desireable space goal at the moment. Geological industry and geological related businesses are seeing that it may be a way of turning a profit. European businesses are ready to team up with the ESA and get a Moon mission off the ground.

Russia is also on board the Moon mission idea and has private sector partners that are putting together their plans for a Moon base to be a reality within another decade or so. The plan to go robotic, rather than have boots on the ground, is what may be the saving grace of this Russo-European Moon dream. It is much more feasible and economically achievable when human survival technology is taken out of the formula. Russia and Europe may end up leaving the Americans in their dust by not only achieving an orbital Moon base but also a similar orbital Mars base with astronauts orbiting safely and controlling rovers and robots down below on the dusty, red surface.

So, now the gringa may have to change her vocabulary. Instead of, “To Mars! To Mars!” I may have to channel the late, great Jackie Gleason, “To the Moon!”

The Real Cassini of the Stars


The name “Cassini” is a bit of a give away that this mission is a cooperative project with NASA and Italy’s space agency. It is actually called the “Cassini-Huygens” mission, involving also the European Space Agency (ESA). And, no it has nothing to do with high space fashion for Hollywood stars in honor of ol’ Oleg. This Cassini is a photographer of the stars, or, I should say, moons, the moons of Saturn to be exact. The mission is managed from the Jet Propulsion Laboratory for NASA in California although the images for the mission are handled at the Space Science Institute in Colorado. The Cassini spacecraft has returned some fantastic images from Saturn’s moon “Enceladus” this past October. Although this cold, icy moon may look like a dead globe of dust, it actually has an active southern polar region.

The probe passed as close as 30 miles from the moon’s South Pole and transmitted data for several days. What sort of data? Most of it will be geological analysis of gas and dust. Cassini captured samples from a plume of gas and ice particles when it made its close fly by. The above image from Cassini was taken when sunlight was at an angle so as to make some of the spray from the South Pole geysers visible. Scientists know that there is an ocean beneath the frozen surface of Enceladus and these samples should help to determine if there is any hydrothermal activity going on down below.

And, if there is an active ocean on Enceladus, why would that matter? Because Saturn’s moon would then become a candidate for exploration to study its potential as a future habitable environment.  Although it seems incredible enough that NASA has colonization ambitions for Mars, the space agency would love to add other locales to their list.

Scientists have learned that Enceladus is basically divided into two separate geographical hemispheres. The northern hemisphere is pock marked by impact craters with much less being visible in the southern hemisphere. Southern hemisphere terrain features fractured terrain with linear, ropy features.

Scientists believe the moon’s core to be solid rock and enveloped by an ocean that is sealed under an icy, frozen crust. The southern hemisphere has active jets which vent oceanic spray. This hypothesis is based on the finding that the moon has a bit of a wobble when it orbits Saturn. The presence of a global ocean underneath but not frozen to the icy crust would explain this wobble. It would also account for the plumes of icy spray that have been observed venting at the southern pole.

Scientists suspect that the ocean of Enceladus may also experience tidal type activity which could be the reason why the crust has not frozen solid to the surface of the water. If this is the case, it would be an indicator that Saturn’s gravity keeps the core of Enceladus warmer than was expected. Scientists have been studying Saturn and its moons for over seven years. Cassini will have a final close-up photo shoot of Enceladus in mid-December. Its task is to measure the heat emanating from the interior of the moon. The gringa is hoping for a tropical paradise hidden beneath that frigid surface. I can imagine living like a beach mole never seeing the sun but picnicking beach side in a sauna like atmosphere and catching space fish that have no eyeballs.
