Did An ET Knock On China’s Space Capsule?


Sometimes, when the gringa is home alone at night, or early in the morning after the caveman leaves for work, my imagination goes into overdrive. I get a little spooked. Should an unexpected noise be heard, that’s it. No sleep for the gringa. But what if you were an astronaut, adrift in the vacuum of space, surrounded by nothingness for thousands of lightyears yet “something” came a-knocking?

I tell ya, the gringa would probably die of fright! There’s certainly no hope for fear to disappear when the sun comes up. No waiting around for the hubby to get back. No paranoid call to 911 for the comfort of a first responder to do a quick looksie around. Nope, an astronaut is all alone for the duration of the mission wondering what the heck just knocked on the door and when or if it’s coming back. Guess what? That actually happened.

Word has it that, back in 2003, when China’s first astronaut in space, Yang Liwei, was performing a 21-hour tour-of-duty aboard Shenzhen 5, something came knocking. He described the noise like the sound of a wooden hammer hitting against a metal bucket. So, he wasn’t spooked by a few creaks or phantom noises created in an over-active imagination like the gringa’s. He described a very distinct, and distinctly loud, noise.

If one eyewitness account of such is not enough for the skeptic, there were other Chinese astronauts who also reported the same banging noise. Consecutive missions, Shenzhou 6 and 7, had astronauts returning to Earth and sharing this news in their de-briefings.

The gringa believes it would be the opportunity of a lifetime to travel into space. Imagine the prestige an astronaut must be looking forward to when they get the news that they are slated for a mission. Certainly they envision a future shaped by this achievement. Success is at hand. With respect to their career, they have, indeed, arrived.

How, then, must it come to them as a terrible disappointment to realize that they will forever be haunted by their space experience. Do some astronauts return to an Earth-bound life, riddled with anxiety, swept up in paranoia that they are stalked by other-worldly watchers? Do they spend the rest of their life feeling a coward’s shame because they didn’t have the guts to answer the door and see who was there?

When interviewed by journalists from Xinhua, Astronaut Liwei explained some of these very emotions. He recounted that when he would hear the knocking, he would become very tense. The gringa thinks, “Yeah. I bet!” He would peek outside the windows only to see nothing. Returning to Earth he spent much time with researchers trying to replicate the noise with a variety of instruments and materials. But they were unsuccessful.

As crews for Shenzhou 6 and 7 were preparing, Liwie warned them that they should expect to hear the noise. He tried to put their minds at ease, assuring them that the noise must be a normal, natural phenomenon. But was Liwie telling the truth or making up a comfortable lie?

The characteristics of the noise were:

-random timing

-no rhythm

-acoustic quality of wood on metal

The Shenzhou spacecrafts are classified as cargo vessels. The craft’s name translates roughly into “magic boat” or “divine vessel of god”. When the craft was first put into use in 1999 by China it was an unmanned vessel. After several successful unmanned missions, Astronaut Yang Liwei achieved the first successful manned mission October 15, 2003, completing 14 orbits around Earth within 21 hours.

The 2 manned missions that followed also reported back the strange noises. Could this be why the 2011 mission was unmanned except for 2 test dummies? In 2012 manned missions resumed with a 3-person crew delivered to China’s Tiangong-1 space station in 2012, 2013 and a final mission in 2016 delivering crewmembers to China’s Tiangong-2 space station. One more mission is slated for 2018 but no details are yet available on whether it will be manned or not.

The spaceship’s technology has roots in Russia’s Soyuz technology. The modified Chinese version features 3 modules. Upon returning to Earth, only one module, the re-entry module, makes the return trip. That means that 2 modules, the orbital and service modules, do not have the same bulky heat shielding as the re-entry module.

The orbital module is constructed of aluminum. This is where the crew spends most of their time. If a piece of space debris came into contact with the outside of the module, it would probably make quite a noise.

But would a piece of debris make a single contact noise or might it bump around the perimeter of the craft a few times until it went on its merry way? Would a tiny bit of space junk, too small to see out a porthole make a noise as loud as Liwie described? Could the spacecraft survive an impact with a small piece of space debris? How likely is it that this is the source of the noise? Yes, the gringa is filled with questions.

NASA estimates more than half a million bits of space junk are floating around Earth. They can travel as fast as 17,500 mph. Even a pebble-sized bit of debris can wreak havoc and cause quite a bit of damage. Check out this picture provided by the European Space Agency (ESA). A solar array on satellite Sentinel-1A took a hit from a tiny bit of space junk (about a 1 millimeter bit) and it punched an enormous hole in one of the solar panels. The size of the damage was about 100 times the size of the junk that hit it.

6.1.2

In 2014, just 6 years after the last Shenzhou mission with a crewmember reporting the strange knocking noises, an important book was published. In “Forging China’s Military Might” much of the material discusses the nation’s space program. It is proposed that spacecraft design should feature a “bumper” to absorb meteor and space junk impacts. Proving the point that even micro-debris can be deadly, the author points to the Space Shuttle Challenger 7 mission. A tiny fragment of debris, and when the gringa says tiny, she means tiny, the debris was a FLECK OF PAINT… it caused so much damage the entire window had to be replaced.

6.1.3

So, did Liwie hear an ET knocking on his spaceship door? Probably not. It’s more likely that it was a bit of cosmic rubble knocking about.

There REALLY IS Life On Mars (And The Moon)


What if the gringa told you that there was, without a doubt, life on the Moon and life on Mars? You might not believe me if you are a strict science enthusiast. You might believe me without hesitation if you’re a UFOlogist. You might hope that I’m telling the truth if you are a science-fiction fan.

Well, the gringa’s got exciting news for all of you. It IS true and there is proof and NASA testimony to back it up. But there’s a curious twist. The life discovered in both locations is not alien. It is very Earth in origin. What does this mean?

The strict science-evidence buff will say this of course means that NASA scientists have contaminated the regions they have explored. UFOlogists will claim it is trace evidence of mankind’s ancient extra-terrestrial ancestry. Science-fiction fans will simply shrug, nothing coming as a surprise to them.

The first thing to do is examine the decontamination procedures of NASA. Is it possible to launch space exploration vehicles that are not contaminated with even microscopic traces of Earth sourced materials? Nope. If complete decontamination is not possible, are there Earthly micro-organisms that can survive the harsh conditions of space travel, be delivered to an alien landscape and, ultimately, thrive only to be discovered later by exploration equipment? Yep.

NASA does not fly solo, determining unilaterally decontamination procedures before or after a space flight. About 50 years ago the Committee on Space Research (COSPAR), comprised of UN members from the International Council of Science (ICSU), created the Treaty of 1967 which outlined certain protocols related to outer space travel and research. Contained within the document are guidelines for 5 categories of space missions, rated according to the risk of contamination posed.

  • Category 1: Any mission to celestial body that does not involve study of biological systems (like launching of an orbiting satellite).
  • Category 2: Any mission to any cosmic body within our Solar System where documentation of biological or chemical systems involves a remote chance of contamination (like when a satellite takes a sample of a vent plume to see what kind of gas it is without entering a cosmic body’s atmosphere).
  • Category 3: Any mission with a specific purpose of studying chemical or biological systems that may contain living organisms that poses a risk of introducing contamination to other cosmic bodies (as in taking a satellite sample that could involve an orbit or fly-by into a cosmic body’s atmosphere, elevating risk of picking up atmospheric particles that could cross-contaminate another planet, moon, etc.)
  • Category 4: Any mission that lands equipment on the surface of a cosmic body for the purpose of interacting with the natural processes of the extra-terrestrial body which will certainly create the possibility of introducing contaminates from Earth to a celestial body (this is what occurred with the Lunar Apollo and Mars Rover missions, the equipment at risk of contaminating the Moon and Mars with Earth organisms).
  • Category 5: Any mission that has equipment set down on an extra-terrestrial body and returns physical samples from an extra-terrestrial body to Earth. This creates 2 subcategories of Restricted and Unrestricted. If the host for the sample is rated a Class III stringent, in other words, not a host for possible life, the returning sample is considered Unrestricted. Any specimen returning from a cosmic body where life is possible, must go through severe decontamination and quarantine protocols.

But how effective are these guidelines? Well, considering what happened with the lunar missions in the 1970s, none of these protocols may even matter. Even though there were procedures for quarantines and decontamination, there was simply no baseline to compare against any data.

Astronauts, equipment and geological samples were quarantined in isolation units for 3 weeks after a “bath” in a super-bleach solution or a betadine wipe-down. An examination for biological, bacterial and chemical anomalies would determine whether or not there was any risk posed by releasing from quarantine. And what about alien contaminants that had dormancy periods longer than 21 days?

Not all returning Apollo mission “stuff” was scrupulously cleaned and monitored. You know the raft the astronaut crews rode in from the module that splashed down to the ship that picked them up? Yeah. It just got a wipe down with betadine and was then sunk in the ocean. And guess where Earthly biological life as humans know it is theorized to all begin? Yeah. In the oceans. Hm. That might not have been such a good idea. That raft may have just been converted to a lunar life nursery.

And you know the geological samples the astronauts returned? Those “Moon Rocks”? Yeah. They didn’t even get quarantined or a splash of Lysol. They were whisked away in a helicopter and taken to NASA laboratories in Houston. So that means a couple of pilots, their crew and an entire helicopter were not just contaminated but blazed a trail of contamination across the sky of half of the United States. The helicopter and crew were quarantined but what about all of that airspace? Yeah. There’s that.

So, basically, humans have already cross-contaminated the Moon and Earth. That means any samples that pop-up on either locale that indicate alien life from one or the other are suspect.

The same is also probably true for Mars. Chances are Earth-origin micro-organisms have probably already survived the trip,arrived and set up shop for the next millennia or two. And, if climate change continues on course, Earthlings may not be around to explain human life on Mars for the ETs that eventually discover them. They will be on their own to figure out that little conundrum.

Which poses the question. Is that how life on Earth originated? Are humans the ancestors of alien contaminates? Could be.

And what is NASA’s solution if samples are determined to be contaminated with biological matter that is a threat to humans? If a danger is discovered en-route back to researchers on Earth, their fall back plan is to fly the stuff into the Sun. Hmm. Yes, by all means. Let’s continue our practice of pollution and let the chips fall where they may.

A Triple Play Cosmic Conspiracy


(Originally published 1/30/17 on Read With The Gringa)

Mars, Utah and Germany are all in cahoots together. NASA and the European Space Agency (ESA) have been conspiring together for years and now evidence of their plot can be found in Utah. Yes, they thought they were clever, selecting a remote and rugged location, inhospitable to human life, in order to keep out prying eyes. But their schemes have been foiled. The gringa has discovered the truth of their cosmic conspiracy triple play.

I have discovered intelligence, yes, special intelligence. Intelligence that speaks with a German accent and rolls about the dust and craters surrounding the desert wilds of Hanksville, Utah. Cosmic conspiracy agents have been spotted in this region and are said to have the uncanny navigation skill of a Himalayan Sherpa and the adorability of a frisky coyote. And all controlled by the whims of German taskmasters. But what are they, the dear reader asks? What are they doing? What does it mean? Well, the gringa’s gonna tell you.

The whole world knows that global space agencies are itching to get to Mars. Scientists and engineers are all engaged in frenzied efforts, developing the technologies to make a successful mission possible. One thing astronauts will need on such a long-term deep space mission will be robots that can think for themselves, AI’s (Artificial Intelligence). There will be no shirking of duty on a mission like that. Everyone has to be capable of doing their part, even the robots. No slacking and leaving your duty for someone else to perform.

It seems that Germany has come up with a great design for a couple of robotic rovers, CoyoteIII and SherpaTT. However, seeing as how Germany is sorely lacking in landscapes that are similar to Mars, the good people of Utah have played host to NASA and the ESA. Exploring the crevices, rocky hills and dusty craters of the terrain around Hanksville is the work of the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI). Boy, those Germans are precise, that’s for sure. What a mouthful!

Now, these German scientists didn’t just dump costly technology off and wash their hands of the whole mess. They also aren’t managing their robot trials nearby, bunking with the locals. They are engaged in a more accurate enactment of what it would be like to work with a robot that is as far away as Mars. The robots in Utah are controlled by scientists in Bremen, Germany. “But what are they doing with them,” the dear reader says. The gringa thought that you would never ask.

It seems that there are some issues with how these babies get around. Although technically considered rovers, that doesn’t mean they are limited to just rolling about.  There were some issues to work out with the legs, navigating tight spaces and collecting geological samples. And, according to DFKI, the Utah tests were a success.

For now, there are no definite plans for Mars, but the gringa can see where these scientists are going with this technology. They will first use it to explore non-human capable places like underwater volcanoes with a tenuous future goal of searching for water on Mars. All the gringa can say is that the control center in Bremen looks like the most amazing video arcade. I may scrap my ambitions of becoming a space gringa, soaring through the heavens in a spacecraft, for operating gizmos like this. Check it out and see if you agree with me.

You Lost What?!!


 

Tell me it ain’t so, NASA. Tell me that you didn’t really lose the original tapes of the Moon landing. I mean, what were you thinking? The one time in ALL of human history that a human being sets foot on a patch of ground that IS NOT Earth and you don’t have the best proof that it really happened in some sort of Fort Knox type security vault? Really? You lost them?

The gringa is torn between being hopping mad and curiously perplexed. Since I recently discovered just how bad being mad is, I will try to cultivate stronger feelings of perplexity.  But NASA didn’t just “lose” the tapes. No, they ERASED THEM! They recorded over the original footage. Anything we see today is a “restored version of the original”. In other words, a copy, a cheap imitation, something that ain’t quite true.

Again, the gringa has to ask NASA, “Who in their right mind ERASES and TAPES OVER the original footage of the most historical moment of mankind’s modern history? Who, NASA? Who?” I mean, the gringa hasn’t even taped over my oldest son’s ballet recital when he was 3-years-old and thought dressing up in a pink sequin outfit with bunny ears and a cottontail and performing on stage was the coolest thing ever. I still have that tape. I don’t even own a VCR anymore but I STILL HAVE THE TAPE! Are you kidding me NASA?

You know what this does for the gringa? It calls into question all the validity of the Moon landing altogether. The gringa clings tenaciously to the hope that the Moon landing was not staged. The gringa wants to believe in the noble cause and purpose of America’s space agency. The gringa does not want to believe that her government was willing to stage a bit of Cold War propaganda with NASA when it was a fledgling organization. But stuff just keeps coming up that makes the gringa continue to scratch her head and think that Moon landing conspiracy theorists may have gotten this sordid tale right.

Why in the world would the original footage ever be considered unimportant enough to tape over? Unless it was footage of a staged event that modern videography experts can now pick apart detail by detail with sophisticated technology and techniques to expose it as a fraud. The gringa is trying so hard not to feel anger.

So, basically, way back when, on July 16, 1969 President Lyndon B. Johnson (LBJ) and his wife, our First Lady affectionately called Lady Bird, watched Apollo 11 launch from Kennedy Space Center in Florida, hurtling Neil Armstrong, Buzz Aldrin and Michael Collins toward the Moon, maybe. Four days later what we have always believed the world has seen, a grainy video of Neil Armstrong “Moon walking” and saying those famous words, “That’s one small step for man, one giant leap for mankind” was the next big event after the launch. And the next big event after that? In 2006, nearly 40 years later, NASA fesses up that the original video cannot be located.

After an investigation, led by Rich Nafzger, NASA discovered that the original footage had been part of a batch of videos that had been magnetically erased and re-used. My, how convenient. Their excuse was that the original video had only been intended for live broadcast, never for re-airing. Why? All throughout television history live broadcasts have been re-aired. And wouldn’t scientists want to preserve the true video feed of the one and only FIRST time a human has walked around on another surface other than Earth? I mean, apart from historical value, isn’t there other scientific, safety and training value to such video?

So now what we see are copies originally furnished by CBS News that were restored by Lowry Digital. The new versions have cleaned up the images to be more clear. So what of the footage of following Moon landings, five more that occurred between 1969-1972? Does NASA have original video footage of astronauts gallivanting on the surface of the moon for those? And who was this Lowry Digital? What kind of reputation did this Lowry production company have?

Here are all the Moon missions when an astronaut walked on the Moon’s surface:

Apollo 11 – Neil Armstrong & Buzz Aldrin walk on the Moon:

Apollo 12 – Pete Conrad & Alan Bean walked on the Moon.

Apollo 14 – Alan Shepard and Edgar Mitchell walked on the Moon.

Apollo 15 – David Scott & James Irwin walked on the Moon.

Apollo 16 – John Young & Charles Duke walked on the Moon.

Apollo 17 – Eugene (Gene ) Cernan & Harrison (Jack) Schmitt walked on the Moon.

(Apollo 13 – Uncompleted mission with a harrowing crisis and narrow escape and recovery)

Lowry Digital has restored all sorts of movies like Bambi, The Robe and Star Wars. Considering the quality of science fiction productions during 2009 when the original Moon landing tapes were restored, sure, it’s possible to have faked the production. But then there’s the reality that the original footage of five other Moon walking missions are in existence. So, the gringa believes that where conspiracy theorists are concerned, the status of the first Moon landing’s original footage does, indeed, make for good fodder for the conspiracy gristmill. However, when you weigh it against the other videos NASA has that proves that astronauts actually did land and walk around on the Moon throughout the following decade, the balance tips in favor of NASA credibility.

Whew. That was close. The gringa is sure glad she followed that little trail to a happy conclusion!

What Should We Fear? I Forgot!


The gringa is more than happy to cheer on Obama’s goal of getting the U.S. space program to Mars within the next 15 years. I should still be young and vibrant enough to don a space helmet if the call to serve my country arises! In fact, considering the latest news on expected conditions for Mars destined astronauts, someone like me might be the astronaut of choice.

Whereas, before, the gringa always believed that epilepsy would probably be a big disqualifier for space travel, turns out a bit of brain damage is probably just par for the course for a Mars trip. Heck, then, maybe I’ve already been there and didn’t even know it! Could be those alien abduction conspiracy theorists have been right all along!

Doctors are still mystified about what causes epilepsy. Maybe all of us epileptics were abducted by space aliens, taken to Mars in an instant through a wormhole, had all kinds of crazy medical studies performed on us, then returned home in the blink of an eye. All that radical space/time continuum dazzle frazzled our brains!

Or… maybe us epileptics are all originally FROM Mars! Now wouldn’t that be something. The brain damage expected to be experienced in a flight from Earth to Mars may have the same effect in a reverse course from Mars to Earth. Maybe I was switched at birth with a real Earthling by Martians who took my doppleganger to Mars! Wouldn’t THAT be something!

So how does travel between Earth and Mars, regardless of which direction you’re headed, end up casing brain damage? Two words… cosmic rays. It’s a long journey from the Big Blue Marble to the Red Planet and then back again. The effects of being exposed to cosmic rays for about one year would be neurological impairments that would affect an astronaut’s judgment and cognitive abilities. In addition to the space brain effect, prolonged, long-term exposure to radiation is pretty much a guarantee that Mars bound astronauts are going to end up with some form of cancer and a weakened immune system that couldn’t even fend off a bout of sneezing.  But how do researchers know this, or suspect it, if no one has traveled between Mars and Earth (that we know of… the gringa is still musing the possibilities of her origins…)

Studies have been conducted at the Brookhaven Laboratory in New York. Leading the research is a team of scientists from the University of California Irvine. They used the particle accelerator at the laboratory to simulate the Earth-Mars travel condition scenario on rats. What happened is that the rats suffered serious neurological damage. They became dumber… unable to remember which meant unable to learn. Even worse, as far as the gringa’s concerned, they lost their natural ability of “fear extinction”.

“What is “fear extinction?” the dear reader asks. Well, the gringa’s gonna tell you. From the time we are babies all sorts of things happen to us that traumatize us with fear. The human brain is an amazing thing. It has a powerful survival instinct that triggers all sorts of protective measures and responses that are automatic. Sometimes we don’t have to try at all when it comes to saving ourselves. Our brain automatically performs an extinction of the fear reaction to certain stimuli.

You see, when something scary happens, like a mom or dad that jumps out and yells, “Boo!”, scaring the baby, the first time the baby probably cries like the dickens, scared to death. However, as mom and dad continue to do this the baby’s brain learns that nothing really bad happens even though the fear response is automatically triggered when startled. Eventually the baby no longer cries when someone jumps up and says, “Boo!” In fact, the baby may even learn how to laugh.

As we grow and have all sorts of life experiences, this happens all the time. That’s how we are able to actually enjoy fear, like watching scary movies or telling spooky tales at campouts or visiting haunted houses or pranking loved ones. But a trip to Mars destroys this capability.

When the gringa puts together the entire picture of an astronaut’s mental condition upon arriving to Mars, she’s not so sure they will survive. Think about it. A Mars team would be:

  • Physically ill (early stage cancer with little to none immunity)
  • Critical information would be forgotten related to their survival (impaired memory may result in no longer remembering how to operate complex technologies their lives depend on)
  • Even if they are in contact with Mission Control on Earth who could talk them through an important process, they are not able to understand instructions (cognitive abilities impaired)
  • In a strange place so far from Earth, unable to master the necessary skills to survive, the realization of their doom would trigger immense fear that would be uncontrollable (the fear extinction response is destroyed)

If anyone has read “Lord of the Flies” it is no big stretch, then, to surmise what might result from this accumulation of trouble… a mission crew that becomes unreasonably paranoid, dangerous and turns on one another. Until the world’s space programs come up with a way to effectively shield Mars bound astronauts from cosmic rays, the gringa has lost all interest in a manned Mars mission. Although my personal level of brain damage can be frustrating, at least I can enjoy a good helter-skelter horror flick without turning on the caveman with a butcher knife.

NASA, Please Explain


Why hasn’t mankind been back to the Moon? Why do humans only travel as far as the International Space Station (ISS) and no further if Russia and the United States have already had successful Moon landing missions? These questions fuel the conspiracy fires that claim the Apollo Moon landing was a staged scene and never really happened. Regardless of a person’s position on this, what of Russia? If they made it to the Moon, why haven’t they been back either?

During the years of the Cold War between the U.S. and the Soviet Union, it was always a game of one-upmanship. Rather than flinging bombs at one another it was a bit of “Whatever you can do I can do better.” The space race was no exception.

In 1961 the Soviet Union took the lead in the space race when Yuri Gagarin orbited the Earth and returned home, all in one piece. In response, U.S. President John F. Kennedy did not say, “Well done.” No, instead he threw down the gauntlet and swore that the U.S. would out-do the Soviet’s achievement. He declared that within a decade Americans would have a man on the Moon and back home safe and sound. Eight years later people around the world watched televised broadcasts of Neil Armstrong planting a U.S. flag on the surface of the Moon. Or did he?

What we know now compared to what we knew then may cast great doubt on the legitimacy of the Apollo mission. Accusations that film director Stanley Kubrick prepared a fake production staged with the latest technologies of 70s era filmdon may actually have credibility. Consider the most common criticisms that point to the film being a fake:

  • Wind mysteriously blowing a flag that should be in the vacuum of space.
  • Anomalous shadows cast in different directions which would indicate multiple sources of light.
  • No disturbance of lunar dust or the Moon’s surface from the landing of the space module.
  • What are the strange objects that are reflected at different times in the visors of the astronaut’s space helmet?
  • Where are all the stars that should be in the background?

Skeptics of conspiracy theories can argue away these questions. For years the gringa has been inclined to believe in the Moon landing as an event that really did happen. My reason being that, for one thing, think about how many people would have to be in on such a crazy secret for all of these decades. I don’t know about you, dear readers, but the gringa’s pretty certain that somewhere along the way, throughout all of these years, surely someone would have cracked.

Despite my confidence in NASA, however, the gringa must admit that by becoming informed about the Van Allen radiation belts, I may have to change my position. This may be the smoking gun that exposes how the entire world has been duped. The U.S., desperate to remain relevant and seen as the most powerful nation, outperforming its most aggressive global competitor, may have gone so far as to stage the most incredible hoax of all time.

You see, the Van Allen radiation belts surround the Earth. Consider these belts to be an enormous layered donut and the Earth the donut hole. They radiate outward as far as 36,000 miles depending on whether they are expanding or contracting. The innermost ring generally spans from 400-6,000 miles above the surface of the Earth. The outer belt stretches generally from about 8,400-36,000 miles above Earth. The ISS is safely tucked into orbit at a mere 230 miles from the Earth’s surface in what is called a Low Earth Orbit (LEO). Orbiting between the two belts is a GPS satellite set 12,500 miles away, just inside the innermost rim of the outermost belt, where radiation levels fluctuate according to waxing and waning cycles. Just within the outermost layer of the outermost belt is NASA’s Solar Dynamics Observatory in geosynchronous orbit at 22,000 miles away studying the mess solar radiation makes from time to time.

In addition to the Van Allen radiation belts is the problem of a cloud of cool, charged particles which envelopes most of Earth’s outer atmosphere. Its nearest edge is about 600 miles from the surface of the Earth and extends outward and stops just inside the outermost edge of the furthest Van Allen belt. Scientists call this cloud the plasmasphere. It seems to cause particles in the outer belt to scatter. As the electrons scatter they create a loop which becomes a well defined belt. The plasmasphere is responsible for creating and maintaining the belts. When a powerful solar event occurs, such as a solar flare, some of the belts’ electrons can be forced by these extreme conditions into the space void between the belt layers, thus creating the waxing and waning effect of the belts.

The craziness of this relationship boggles the gringa’s mind. Think about it. The electrons are prevented by Earth’s magnetic field from penetrating all the way to Earth and frying all of us Earthlings. However, they also do not have enough energy to escape and dissipate into outer space. Thus they are trapped in this belt system which results in a protective barrier that traps dangerous radioactive solar radiation so that we don’t all get fried. Without the belts we fry. Without the plasmosphere we fry. Without the magnetosphere we fry. And if we hang out in any of these Earth preserving regions for any length of time we fry. Is that not the most amazing irony? That which preserves us can also kill us.

Considering that the Moon is 238,900 miles from the Earth, these dangerous, radioactive belts must have been navigated safely with the technology available in 1969. The only other option would have been to “thread the needle”, so to speak, by using a trajectory that would have allowed astronauts to travel through a narrow window of space that would have avoided the highest concentrations of radiation within the belts.

If this path had been successfully traveled in 1969, and adequate shielding technology existed, why is the danger posed by the Van Allen belts considered to be the main obstacle and unsolved problem preventing a consecutive Moon landing today? The gringa suspects the answer may lie in the fact that there really was no successful 1969 Moon landing to begin with.

Here are the words and quotes NASA uses to describe the Van Allen belts today:

  • 2 donuts of seething radiation.
  • Impenetrable barrier.
  • Wax and wane.
  • Expose satellites in low-Earth orbit to damaging radiation.

So what did NASA do to deal with the dangers of the Van Allen belts? Did they come up with a competent strategy and deliver the real deal with a man on the Moon or did they scam the entire world?

Newly discovered in 1958 by scientist James Van Allen, not much was known about them two years later when the first solution was offered up. In 1960 Robert O. Piland and Stanley C. White told NASA that hoping to shield astronauts effectively from the radiation was impractical. They did believe they could provide moderate protection and a safe enough route that would enable astronauts to not fry as they passed through the outer belt.

NASA got to work with a Group On Trajectory Analysis. Van Allen, himself, suggested that by detonating a nuclear warhead the crew could clear a path of travel. The gringa can only say, “Thank goodness NASA didn’t do that!” However, the defense industry in the US really mucked things up by nuclear testing which only increased the intensity of the radiation levels in the belts.

In 1964 NASA officials were confident that with the right skin on the spacecraft, a layer of protection provided by instrumentation, and the right trajectory, the risk was nominal to the crew. Equipped with dosimeters to record radiation exposure, the gringa is puzzled over the final results as reported by NASA. The agency reports that over the course of all the Lunar missions, astronauts were only exposed to radiation levels that were actually lower than the 5 rem a person working in a nuclear power plant would be exposed to annually. The U.S. Nuclear Regulatory Commission claims that the average American is exposed to a radiation dose of about 0.62 rem annually. A full body CAT scan delivers a radiation dose of 1 rem. So any human going through some rather routine medical procedures can easily reach the same radiation exposure levels as what NASA reported in the Apollo Moon landing crew.

ISS astronauts deal with radiation issues daily. It took the gringa quite a bit of head scratching and calculating to discover how ISS astronaut radiation levels compare to the astronauts of the Apollo Moon missions. They use a different measurement, the SI system. Maybe, if there is a conspiracy, this is by design to confuse amateur sleuths like myself. Anyway, I digress.

Basically one mSv is the equivalent dose of radiation an average person would be exposed to on Earth in one year’s time. Astronauts on the ISS are exposed to 1 mSv daily! This exposure takes place well outside the Van Allen belts in a space station constructed with the latest technology in radiation shielding and manned by personnel equipped with the safest space suit equipment available. How, then, could minimally protected astronauts pass through highly radioactive belts not just once, but twice, and not be ravaged with radiation? If ISS astronauts report a daily radiation exposure equivalent to a year’s worth of radiation back home and are not in the belts themselves, how in the world is the public supposed to believe that the Apollo astronauts were only exposed to the amount of radiation a person would absorb if they had 4-5 full-body CAT scans?

The  gringa has become incredibly skeptical. The gringa is going to be hopping mad if she discovers hard evidence that proves we have all been had. NASA, please explain.

Salute Our Space Heroes


Traveling in outer space sounds fun. Being an astronaut seems to be an exciting career. Until the gringa is reminded about space radiation. Those heavy duty marshmallow looking suits astronauts wear are not just to keep them warm, properly pressurized and surrounded by oxygen. They also protect against dangerous space radiation. But is it enough? Are spacecrafts and the International Space Station adequately protected or are our astronauts slowly being radiated to death?

Radiation is an invisible energy form of high-speed particles and electromagnetics. It surrounds humans in everyday artificial light, sunlight, and electronics that produce radio-, television-, and micro- waves. Radiation comes in two forms:

  • Ionized: This is the worst in the form of gamma rays, protons and neutrons. Exposure to ionized radiation results in exposed atoms becoming unstable by an energy powerful enough to remove electrons from their orbit around the atom’s nucleus.
  • Non-ionized: Not powerful enough to destabilize atoms, this is the kind of common radiation produced by microwaves, radio waves and light.

The radiation in space is, unfortunately, comprised of ionized radiation. There are three things that typically create dangerous space radiation:

  • Trapped radiation: The Earth’s core creates a magnetic field that surrounds our planet up to several thousand kilometers from our planet’s surface. Solar wind carries charged particles that slam into our magnetic shield. Some particles manage to pass through. Those that don’t create a shockwave that deflects from Earth’s magnetic field. This creates layers of cavities called the “magnetosphere” that act as shock absorbers to protect Earth further from charged particle bombardment. But some particles get trapped in these cavities and they become radioactive belts surrounding Earth. Astronauts have to pass through these dangerous belts before they reach deeper space.
  • Galactic Cosmic Radiation (GCR): Outside our solar system ionized atoms traveling at almost light speed pass through space matter, including humans and man-made objects unless they are properly shielded.
  • Solar Particle Events (SPE): Sometimes the Sun flares and ejects copious amounts of highly charged radioactive particles into space. These particles travel so fast they are capable of reaching Earth within ten minutes of a solar or coronal flare event. These are dramatic happenings that temporarily drastically increase radiation exposure.

Astronauts traveling through space radiation or living in the ISS have to be protected from space radiation. Radiation exposure causes damage to human cells. There is a scientific formula used to calculate how much radiation exposure an astronaut can expect when working on the ISS. It’s a bit too complicated for the gringa to understand. These calculations are the reason ISS missions have a maximum six month cycle and spacewalks are limited. Exposure is increased during a spacewalk to perform repairs and maintenance.

Shielding is preferred to be constructed of materials like polyethylene because it has a high hydrogen content. This kind of material is more effective than metals at reducing the ability of particles to pass through and enter the modules. Astronauts also wear monitors called “dosimeters” that constantly measure the level of radiation damage to the chromosomes in their blood cells.

Every single astronaut is a hero. No matter what the duration of their mission. No matter what the nature of their mission. No matter what it is they did, whether it seemed glamorous or insignificant, these men and women are heroes of science. They are risking their lives every moment they are off the surface of the Earth. Even if they return safely, they have still sacrificed much. From musculo-skeletal issues to organ damage and higher cancer risks, every single astronaut will experience the effects of radiation exposure for a lifetime despite the measures taken to protect them. If you ever meet an astronaut thank them for their invaluable sacrifice and service performing critical scientific endeavors that are helping us understand our origins, learn about climate change conditions and create solutions to save our homeworld.
