The Eastward Wobble, The Dance of the Earth


In April of this year NASA released findings related to the Earth’s melting ice sheets. Often when the gringa things about climate change, warming temperatures and melting ice sheets, the only thing I consider is how sea levels will rise. It never occurred to me that ice sheet disintegration may result in a more wobbly world.

Think about the traditional children’s toy, the spinning top. It’s a bit like our world. As it slows its spin it begins to wobble. As ice sheets melt and the balance of Earth begins to shift, we will, indeed, experience a global wobble. Scientists officially define this as a “periodic wobble and drift of the poles”. All the gringa wants to know is, “What exactly does this mean for me? Am I going to fall on my patootie trying to walk to my car?”

NASA asserts that over the past sixteen years Antarctica and Greenland, combined, have averaged about 400 billion tons of ice loss annually. Before the year 2000, as Earth spun on its axis it had a gentle drift toward Canada (westward). Because of ice loss, now the drift is about 75 degrees in the opposite direction, eastward. This happens because as ice converts to water and moves elsewhere, the distribution of Earth’s mass changes. What this means exactly is that the location of the North and South poles will change. In other words, Earth’s axis is relocating.

Now, the traditional location of Earth’s North Pole may have to be renamed to the Northeastern Pole. Earth’s axis is like an invisible pin stuck through the Earth from North to South. The Earth spins on the tip of the pin, rotating with a slight wobble that is normal. However, if the geographic location of the Poles change, complete topographical and satellite telemetry systems have to be adjusted to accommodate this change. For the average person, this means that your GPS is going to deliver you to the wrong place!

Scientists have long known that the Poles shift by a few centimeters from time to time as a part of Earth’s natural climate adjustment cycles. But what we are dealing with now is much more dramatic. Experts estimate that the shift is averaging about ten centimeters Eastward annually. Our great-great-grandchildren may have to adjust Christmas stories to have Santa Claus living in Russia or Norway.

Although scientists understand that as ice continues to melt the Earth will adjust by shifting its axis to the place where it has lost mass, even their best predictions are really just a guess. This is an extremely complex problem. It’s not just melting ice sheets that affect the process but also loss of groundwater in above ground reservoirs and underground aquifers (which underground aquifers cannot be accurately measured) as well as glacier melt and glacier movement. Many glaciers float about the ocean as they please.

The Earth’s ice and water storage formula affects polar drift. Yet many of the variables in the formula cannot be measured or can change their individual affect. So, scientists are left scratching their heads, doing the best with what they’ve got, and hazarding their best guess on what humanity can expect.

Ice melt is not the only thing that can bump the North Pole to a different location. Enormous earthquakes and devastating tsunamis can do the job as well. Indonesia’s great earthquake moved the North Pole eastward by about 2.5 centimeters and also lengthened Earth’s day cycle by 2.68 microseconds. No wonder I’ve been so tired lately! The gringa is filled with wonder at how humans remain at the mercy of nature despite all of our technological advances.

Fun With The Black Knight (No, Not Batman)


“Good grief,” the gringa says. “Not another UFO and secret space mission story to debunk?” Well, dear readers, I’m afraid so. But isn’t it fun to do?! Better yet, during this debunking post the dear reader will learn something very interesting related to the International Space Station which may inspire a space related activity of your own.

The Allegation

UFO and extra-terrestrial fans claim that there is an ET satellite, dubbed the Black Knight, locked in our planet’s orbit and visible from the International Space Station as well as Earth. They believe its purpose is to study mankind and has been present for over 1,300 years. To support this theory, UFO-ologists assert that because the Black Knight follows a polar orbit it is collecting terrestrial data because that is the orbit path used for cartography. UFO-ologists offer for proof a Russian space agency video where it is alleged that the Black Knight can be seen in the background as a Russian supply ship approaches the space station.

The Truth We Know

There is no doubt that unnatural objects are floating about the Earth in an orbital cycle which then makes all of these objects, technically speaking, “satellites”. However, it’s all just man-made space litter, debris from the space station or shuttles or other spacecraft. Some of this debris is electronic in nature, emitting signals captured and disseminated from other radio signals by technicians working for space agencies around the world.

The Black Knight was officially discovered about 60 years and announced in the St. Louis Dispatch and the San Francisco Examiner in March, 1954. Six years later, March, 1960, Time magazine published an article clearing up speculation that the Dark Knight was a Russian spy satellite. It was, after all, the era of the Cold War. The article claimed that the U.S. Department of Defense had announced that it was the U.S. satellite Discoverer and had veered off course, destined to its new trajectory around Earth. It is monitored even today by the United States, Europe, Russia and China.

The Fun We Can Have

The Black Knight is visible to amateur astronomers. As soon as the public became aware of its presence, people began tracking it on their own throughout the 1950s and 1960s. It appears to the naked eye as a red light moving quickly across the sky from East to West. Even today Earthlings can peer up at the night sky at the right time, looking at the correct horizon and track the path of the Black Knight as well as the path of the ISS. Orbiting about 240 miles above us, the ISS will appear like a fast moving airplane. It will be an unblinking white pinpoint of light. It shines so bright even city dwellers can see it. By visiting NASA-Spot The Station you can sign up for text message or e-mail alerts for your own area with a date, time and horizon parameters to spot the station as it passes over.

If a dear reader has access to a telescope, you can take a peek at the Dark Knight as well as the International Space Station. To help locate the station there is an online guide:  NASA Human Space Flight Realtime Data tool. Once you have spotted the station with your eye, you just point the telescope that direction in a forward trajectory. Eventually the ISS will pass through your viewer. It can all happen within seconds. Don’t fret if you fail the first time or two. Keep practicing and sooner or later you will get to see the ISS! Maybe even the Dark Knight! As you gain experience, or, if you have a fancier telescope with automated trajectory tracking, you can follow the ISS’ trajectory, keeping it in sight for much longer viewing.

The gringa’s pretty certain that if space aliens, Earthling governments and space agencies of the world were trying to pull one over on us, hiding a secret ET spy satellite, they are doing a pretty poor job of it since any ol’ soul can see it with or without a telescope!

Life In A Bubble


There are many different reasons to be interested in the science of climate change. Maybe you are a lover of nature, like the gringa. Maybe you are a doomsday prepper, anticipating worldwide failures of critical natural resources necessary for humanity’s survival. Perhaps you are a problem solver, interested in creating solutions to help us all survive. Or you could be an author of science fiction and fantasy and the realities of climate change provide a plethora of creative resources. Whatever the reason, then you will find the possibility of life in a bio-sphere bubble interesting to ponder.

Tucson, Arizona was recently host to an environmental event sponsored by One Young World, a group of leaders in innovative climate change survival solutions, particularly Biosphere 2 (Earth is #1).  The event featured experts in science, international diplomacy, political science and commercial industry who are all interested in humanity’s need for sustainable sources for food and energy. The speakers whom event attendees were, perhaps, most interested in were probably the former astronaut and individuals who have been living in Biosphere 2.

If a person was to take a tour of Biosphere 2, you might be expecting a sterile, technical, enclosed life support environment like the International Space Station. However, you will probably be pleasantly surprised to find a faux ocean the size of an Olympic swimming pool surrounded by a bamboo forest. As you continue exploration, you will stumble across a desert recreation complete with species of ants and cockroaches.

The Biosphere idea was birthed more than two decades ago. In 1991 the dream was realized when eight individuals, four women and four men, donned their uniforms and entered the three acre terrarium smack dab in the middle of an Arizona desert where they would live confined for twenty-four months.

The habitat was constructed thanks to the generosity of a wealthy Texan who wants a place of safe retreat when the Apocalypse crashes down around our ears. He shelled out about $150 mill to recreate miniaturized versions of South America’s rainforest, the African Savannah, and a single ocean. The Biosphereans worked for two years to determine if this earthly microcosm would interconnect, survive and become a self-sustaining world producing oxygen and food.

Beneath the multiple geodesic domes of steel, glass and plastic transplanted nature began to fail the moments the doors were sealed. Precious oxygen was leaking and making its escape to the outside world. Despite the threat of suffocation, the Biosphereans soldiered on. They planted crops near the ocean. A sophisticated underground bellows system created wind. But small crops of oxygen producing plants and man-made breeze were not enough to make the habitat a survivable, much less pleasant, environment. For the sake of science the Biosphereans persevered through two years of oxygen deprivation yet finally called it quits when survival was only possible by pumping in outside-sourced oxygen.

But was this experiment really a failure? Of course not. It was a very valuable learning experience. Think of all the research that was accomplished on learning how vegetation, geography, water and air movement, and fresh water sources can all be successfully recreated and the knowledge of certain mistakes not to repeat in the process.

The Biosphere 2 is not a total physical loss either. The University of Arizona will continue studies on how to succeed in a biosphere lifestyle. Part of the property will be open to the public and re-christened “Land Evolution Observatory”. The university will launch a project that, over the span of a decade, will attempt to perfect the methods the Biosphereans began. The gringa considers these self-sacrificing and brave Biosphereans to be the pioneers of the Millennia.

The Biosphere story also has a romantic twist. The gringa, madly in love with her caveman, loves a good romance and is happy to learn that two of the individuals fell in love during their confinement together and married as soon as they had regained their freedom to the outside world. The couple, speaking to the Tucson audience, explained how profound their sense of inter-connectedness to their environment became. Daily they tracked carbon and oxygen levels, strongly aware that their survival depended on the right balance.  They felt aware, moment by moment, of each breath they took and each CO2 exhalation they made. The reality of the co-dependence the humans, plants, animals and insects all had with one another was always at the forefront of their mind.

When former astronaut Ron Garan addressed the audience, he discussed his six month stint enclosed in the self-sustained environment of the International Space Station. It was a profound experience that increased his environmental awareness and how tiny, fragile and singular our Earth is. His individual life perspective was completely changed as he worked beside the two Russian cosmonauts he shared duties with. Upon his return to Earth, he dedicated himself to collaboration with projects that will promote the survival of humans and the planet we call home. The only planet, mind you, that we have.

He recounted one of his most poignant experiences. It was the moment he returned to Earth. He peeked out the window of the capsule, saw a landscape of rocks, flowers and grass. His immediate mental and emotional response was, “I’m home” despite the fact that this American was actually in Kazakhstan. Once you’ve been off world, any square inch at any spot on the globe is home, regardless of politics, religion, nationality or ethnicity. The gringa finds this philosophy beautiful and inspirational. And I hope that we all figure it out together, how to save our home.

India’s Space Explorers


The gringa has done innumerable posts on NASA, several on the European Space Agency (ESA) and even the space programs of Russia, China and Japan. Were my dear readers aware that India has its own space program? They do. It is called the Indian Space Research Organization (ISRO) and they are now on the brink of exploring the galaxy with their own re-usable shuttle.

To India’s credit, they have accomplished the feat of designing and constructing a reusable launch vehicle for a fraction of what SpaceX spent on their reusable rocket. If their shuttle model is a success, the world may have to turn its eyes to India as the next world leader in space program development and exploration. Not only are they getting things done, but doing so extraordinarily efficiently.

On its virgin flight, the 21 foot long shuttle, weighing one and three-quarter tons, reached Mach 5 as it zipped through space 39 miles above Earth. The craft successfully splashed down right on target at coordinates in the Bay of Bengal. This prototype is much smaller than NASA shuttles but if the design is right and all goes well, India plans to enlarge the shuttle’s length by one hundred feet by the year 2030. By designing a re-usable shuttle, India will realize a 90% savings with every single launch. Cost was the very reason NASA’s shuttle program was discontinued.

Aerospace experts around the world view India’s achievement with great interest.  By drawing upon the successes and failures of other space agencies around the world, India has developed a space program that has avoided costly mistakes. They have also been able to model their inspirations upon the successes that have been accomplished. India is managing a successful and growing space program with a budget that, on average, is about three times smaller than their Western counterparts. One reason is that they have eliminated much of what we Westerners call pesky bureaucracy.

Going red tape free, however, is not without its risks. Only time will tell if lack of regulation results in a more hazardous space program. Re-usable shuttles should translate into multiple launches annually. This will mean more money for the space program by infusions of cash from investors and contractors who want their payloads delivered to the International Space Station and other countries paying cab fare for their astronauts to hop a ride.

At the rate India is clipping along with progress at a significant lower price, they may just boot SpaceX out of the space transport market altogether. Who knows, it may be India that gets to Mars first. And according to the stock market, investors seem to have the same suspicion. The companies involved in supplying ISRO with the materials they need have become quite attractive for foreign and Indian investors.

The gringa has always wanted to visit India. It’s rich history and beautiful culture has always intrigued me. Now, I have hopes that in yet one more country on this grand globe, this astronaut hopeful has just one more option of space programs that, one day, may be interested in sending a gringa into outerspace.

Buzzed By Space Junk or ET’s?


In 2017 Earth is expected to be “buzzed” by a mysterious object being tracked by satellites and called “1991 VG” because in 1991 it did its first recorded fly-by of our planet. In December of that year the object, which is about 30 feet (10 meters) across, buzzed past Earth as it continued in its orbit around the Sun (called a heliocentric orbit in fancy Science-speak). Stargazer James Scotti at University of Arizona’s Kitt Peak observatory, using the Spacewatch telescope, spotted VG in November and continued to track it as it passed by.

Observers noted that it shone brightly but this brightness would often go through rapid fluctuations. Scientists argued that this was indicative of it not being an organic object like an asteroid. Could it be a man-made piece of space junk that has been destined to orbiting the Sun until it disintegrates? Well, let’s see just how much space junk is out there in a heliocentric orbit:

American Space Junk

  • Pioneer 4 (1959)
  • Ranger 3 (1961)
  • Mariner 2 (1962)
  • Ranger 5 (1963)
  • Mariner 3 & 4 (1964)

  • Mars Observer (1992)
  • CONTOUR (2002)
  • Genesis, Spitzer Space Telescope, Kepler Telescope, STEREO-A & STEREO-B

Russian Space Junk

  • Luna 1 (1959)

European Space Junk

  • Helios 1 (1975)
  • Helios 2 (1976)
  • Giotto (1986)
  • Ulysses (1990)
  • Herschel Space Observatory & Planck Observatory

Japanese Space Junk

  • Sakigake (1985-1999)
  • Suisei (1985-1991)
  • Nozomi (1998-2003)
  • MINERVA mini-lander (2005)
  • DCAM1 & DCAM2 (2010)
  • ARTSAT2:DESPATCH (2014)
  • IKAROS, SHIN-EN, & SHIN-EN2

Chinese Space Junk

  • Chang’e2

India Space Junk

  • Mangalayaan (2013-2014)

Despite the number of man-made objects orbiting the Sun, there are some space enthusiasts who eagerly await 1991 VG’s arrival, wondering if it might be an alien space probe sent to observe our planet. Scientists don’t know exactly what it is… yet. Here are some of the details they are certain of through telescopic and satellite observations:

  • It has a strange rotation.
  • It has existed a very long time in outer space.
  • It rotates rapidly
  • It has reflective fluctuations

Here are the theories bandied about as to what it could be:

  • Alien space probe
  • Small meteorite
  • Apollo 12 rocket

However, after researching each man-made possibility, they have ruled them all out. So, we are left with the possibilities of a small meteorite or an alien-made object. It’s reflective properties has scientists leaning toward a non-organic object which then leaves only an alien-made object left on the list. However, scientists also do not rule out the possibility of a Russian-made object that the science community is simply unaware of. During the years of the Soviet space program, they were very secretive. Information about failed space missions that resulted in space junk left floating about into infinity and beyond was often suppressed. So, there is the possibility that it is a bit of old, secret Soviet space history.

In tracking the trajectory of the object’s orbit, it can be determined that 1991 was not the first fly-by of VG. It also would have passed near the Earth in March of 1975. Repeat visits are another reason scientists rule out an asteroid or meteor because typically if such an object neared Earth like 1991 VG, it would either be trapped by our planet’s gravitational pull and either burn up in the atmosphere or crash (worst case scenario) or have its own trajectory affected and changed by Earth’s gravity. This object’s trajectory remains unaffected by Earth’s pull.

Because its orbit is very similar to Earth’s path around the Sun, some scientists speculate on the alien observation probe theory. Next summer Earthlings will get another up close opportunity to peek at the object as it skims over the planet’s southern hemisphere.

Edinburgh mathematicians have calculated the very real possibility that extra-terrestrials could be successful at launching observation space probes across vast galactic distances to spy on humans. Their work, published in the Journal of Astrobiology, asserts that by taking advantage of gravitational fields surrounding stars they could achieve the necessary speeds for an observation probe to travel to Earth from the far reaches of space of which humans are completely ignorant of and incapable of exploring. In fact, humans are already using this technology in the Voyager probes zipping about the universe.

Regardless of whether it’s a big space rock, hunk of junk or extra-terrestrial peeping Tom tool, the gringa has her calendar marked for the Summer of 2017. I expect interesting things to happen.

Who Were Those Ancient Siberians?


An interesting Siberian archaeological site is the tittle-tattle of historians recently, squabbling on what ancient people get credit for the structure sitting on an island in the middle of  a lake. It’s over one thousand years old so Russians, as we know them today, are not the culture responsible for this structure. Who the heck needed a fortress in Siberia 1,300 years ago?

Experts have dated it to about 750AD. Situated in the middle of Lake Tere-Khol in Tuva, this high altitude lake location has some historians believing it could possibly indicate religious, astronomical, or imperial significance. The theories bandied about are that it is possibly a regent’s summer palace, a monastery or, perhaps, an observatory for the heavens.

Finding out what was going on in Siberia in the 700s is not as easy as one might think. A trip to Wikipedia (the source of all online knowledge, right?) reveals that Russia’s historical timeline inconveniently begins in 860AD with a record of the Rus’-Byzantine War. Wikipedia has let the gringa down.

Digging back a bit further, things get vague. One simply has to pick up a bit here and bob over there and put together a picture that, although still a bit hazy, can at least deliver a pretty good idea of who the heck was running the show in Siberia in the 750s.

The first stop on the collection route of ancient Siberian bits and bobs is linguistics. Author Rein Taagepera penned a book entitled “The Finno-Ugric Republics and the Russian State”. There is a single quote that sheds some light on the 750s mystery people of Siberia:

“Samic was previously considered a language with disparate dialects but is now increasingly seen as  a collection of half a dozen related languages that diverged some 1,300 years ago. They are spoken in northern Scandinavia and the Kola Peninsula in the Russian Federation.”

Here, at least, Wikipedia did not let the gringa down. Wikipedia explains that the Samic language is believed to have its roots in ancient Finland dating from 1000BC-700AD. The Finnish-Samic link to this Siberian archaeology site is further strengthened by an observation made by Ludmila Koryakova and Andrej Vladimirovich Epimakhov in their book, “The Urals and Western Siberia in the Bronze and Iron Ages”:

“In the sixth-third centuries BC, their northern trade was oriented to southeastern Europe, but after the second century BC, caravans went to western Siberia, where the Sargat culture constituted the most powerful ethnic and political union.”

So, the gringa believes an actual cultural identity can now be assigned to ancient Finnish ancestors speaking the Samic language who settled in Siberia – the Sargats. Researchers identify evidence of this culture in the forested steppes of southwest Siberia near Russia’s fifth century border with northern Kazakhstan. Archaeological artifacts and burial remains show that the Sargats lived a horse herding lifestyle centered around raising sheep and cattle. A nomadic tradespeople, their wares were typically milk products, meat and textiles. Social structure, determined from burial rituals, reflect that women were regarded equally as men with regard to managing herds and local governance. Warrior status, however, was an elite status reserved for only the most wealthy and powerful males.

DNA evidence of remains also revealed a curious Iranian ancestry link as well. So, the Sargats were probably originally Finnish and eventually intermarried with other tribespeople living in Siberia, coming into contact through trade and war. Ancestry for Siberians can be traced not only to Finland and Iran but also to Turkey, Mongolia and China as well as traces of Viking influences.

Interestingly enough, the style of the controversial Siberian structure shows Chinese architectural influences. The official name of the site is “Por-Bajin” and is considered a mystery by the experts who have been studying it for decades. The name is derived from the Tuvan language and means “clay house”.  Sitting near the border of Russia and Mongolia, it is then probably no surprise to see a Chinese influence in the design.

Researchers liken the layout to resembling a typical Buddhist temple. This similarity along with its isolated location and the fact that the cultures of this time were nomadic and not organized in such ways as to see an imperial palace as something useful, causes the gringa to consider the monastery theory to be more credible than a fortress type imperial summer palace or astronomical observatory. Like Catholic missionaries who traveled to remote places all over the world and constructed missions and convents, Buddhist monks followed a similar tradition.

Another curiosity is that the structure lacks any evidence of a heating system, even one that would be basic and crude. Surely that, too, would rule out an imperial summer palace. Siberia, even in the hottest period of a summer season, would still be uncomfortably cool without any heat source within a dwelling. To try to survive a winter without heat would be a death sentence. So, even as a monastery, monks could only be in residence during the summer.

The gringa loves a good mystery and will certainly be eagerly awaiting more news and future developments regarding “Por-Bajin”. With the effects of climate change causing permafrost melt resulting in water levels rising in Lake Tere-Khol, the caveman and I better put it on our climate change related priority travel list to see it before the waters swallow it up!
