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.

The Allure of Conspiracy Theories


The gringa loves real science and also a thrilling science-fiction tale. I don’t get the two confused. I love to debunk a curious space related conspiracy theory and I have to admit I have believed my share of crazy conspiracy theories in my lifetime. However, there is a difference, I believe, between a person who entertains a conspiracy theory as a possibility, explores it for its entertainment value or believes one with the joint purpose of proving or disproving, and the person who is a whole-hearted conspiracy theorist. Where exactly is the line in the sand between the two psyches? Why are conspiracy theories so alluring to otherwise sound, reasonable minds?

Take for example the true believers in a  YouTube video  that contains audio claimed to belong to a Soviet Union era cosmonaut, the first Soviet woman in space, who was killed upon re-entry when her space capsule failed to withstand the re-entry burn.  The video/audio was debunked as a hoax by former NASA mission control technician James Oberg. His career encompasses space journalist, historian, author and he is fluent in the Russian language, an expert in Russia’s space program.

The hoax award can probably be given to the Judica-Cordiglia brothers who perpetrated multiple space related hoaxes throughout the 1960s. These Italian brothers liked to while away the time underground in an old bunker filled with electronic equipment. Although they claimed the equipment was for detecting radio frequencies filled with covert signals that they decoded and revealed to the public, the truth is it was their own private hoax production studio.

They also claimed to have captured the dying words of Vladimir Komarov, a Soviet cosmonaut whose spaceship burned up in re-entry. Back then the public must not have known what we know now… there is a radio blackout during re-entry as radiation and intense heat interfere with the viability of radio signals.

Although the gringa is certain the hoax videos and audios were highly compelling, the truth is equally, if not more, interesting. While Komarov encircled the Earth in a faulty space capsule he had what he knew was his last conversation with a Soviet official who was safely aground on Earth. It is reported that Alexei Kosygin was in tears as the two talked, knowing his comrade was doomed to a torturous death by suffocation in extreme heat before the capsule ever disintegrated into a ball of flames. The United States had listening posts in Turkey where Cold War spies eavesdropped on the emotional exchange as  Komarov vacillated between rage and despair at his horrible fate.

To make the tale even more gripping is the fact that Komarov’s gruesome death could have been completely avoided. The original plan was to launch a second capsule the day after Komarov’s launch. The two space vehicles were to dock together and Komarov would swap places with one of the two cosmonauts in the second vehicle.  This was all scheduled to coincide with the Communist revolution’s 50 year anniversary and was Brezhnev’s victory plan to reveal to the world Soviet superiority.

Cosmonaut Yuri Gagarin was slated for the second space capsule. He made a tour of Soyuz 1 with a group of technicians and they recommended a postponement of launch due to hundreds of flaws in the vehicle. Forwarding the recommendation, inspection report and a ten page memo to Brezhnev through a KGB friend, the buck stopped with the KGB. No one dared defy Brezhnev’s dream of glory because the KGB agent, Venyamin Russayev, as well as every other agent who had knowledge of the communique, were summarily demoted and shipped off to remote areas within the Soviet Union for convenient, out of the way service.

Komarov knew he was on a suicide mission but he went anyway. He is a true hero. When Gagarin’s KGB friend suggested to Komarov to simply refuse the mission, he explained that if he didn’t go, the government would send the cosmonaut who was next in line, which was Gagarin. Gagarin had tried to save Komarov’s life by recommending the mission be scrapped. Komarov turned around and gave his own life that Gagarin’s might be saved. If that’s not a hero, I don’t know what is.

Soyuz I launched April 23, 1967 and almost immediately began experiencing problems and mechanical failures. Due to these problems the second capsule’s launch was scrubbed from the schedule. U.S. National Security Agency analysts (fancy words that basically mean spies) recorded and translated what they could of Komarov’s communications to ground control. They describe a cosmonaut who knew he was going to die. Soviet Premier Alexei Kosygin cried as he told Komarov he was a hero. American records reveal that when the descent parachutes failed, Komarov raged as he entered his death plummet.

This tragic story is as fascinating as it is sad. Why would anyone feel the need to believe a titillating conspiracy theory rather than the tragic truth? And this is not the only case where outrageous conspiracy theories have often been eclipsed by an even more fantastic truth. Consider the following conspiracy theories and their fans:

  • Da Vinci disciples who believe the mysteries in the book “The Da Vinci Code” are real yet the mystery of Da Vinci’s art is even greater than conspiracy fiction.
  • 9/11 Truthers who believe that the U.S. government murdered thousands of U.S. citizens yet is eclipsed by the intricacies of an ideological war by a small group of terrorists that have managed to capture the entire world’s attention, keeping everyone riveted with fear despite their very small numbers compared to the numbers of allied militaries fighting against them.
  • Birthers who believe that President Obama was not born a U.S. citizen is really quite boring when compared to the fascinating, tragic yet triumphant tale of how a young boy became president of the United States of America despite the statistical odds stacked against him.
  • Amelia Earhart fans who believe that she was abducted by extra-terrestrials yet the biography of this amazing, adventurous woman and the impact she has had on the lives of women for decades is so much greater than chasing shadows.
  • Osama bin Laden – conspiracy theorists believe that he is not dead and that the story of his body being dumped into the sea from a helicopter is a cover story. However, the account of the assassination plan by military special forces is the stuff that best selling novels are made of.
  • Princess Diana – conspiracy theorists believe that she was assassinated by the British Royal family and would rather believe such outrageousness when the life of not only this amazing princess but the entire House of Windsor can keep a person riveted to history books for weeks on end.

The gringa would like to know what makes a diehard conspiracy theorist tick. Experts say that they are more than your average skeptic. To selectively doubt certain scenarios or details that are reported by official agencies is normal. But when a critical political view morphs into believing in the omnipotent power of an elite shadow government ruling the world, a real conspiracy theorist is born.

Conspiracy theorists are not necessarily mentally ill despite the fact that they may believe some things that seem outright crazy, unreasonable or illogical. It is becoming such a widespread perspective, psychologists are categorizing it with its own empirical field definition. They explain that distrust is the underlying condition but it is the wrong kind of distrust. It is a form of distrust that is disconnected from critical thinking skills.

Although everyone has trust issues with someone at some point in their life, not everyone becomes a conspiracy theorist. When a person is able to hold on to the general opinion that most people in society are decent people worthy of measured trust, that trust growing as a relationship grows, that is a person managing distrust in a healthy way. However, once a person becomes so cynical that they believe that no one can be trusted, that everyone is out to get something over on everyone else, they are primed and ready to believe that the entire world is at the mercy of global elite puppetmasters.

Conspiracy theorists believe a distortion of the real truth that governments, though corrupt to varying degrees, do have within them some officials who are puppets serving elite interests in order to line their own pockets yet at the same time there are also officials who genuinely want to serve their people. And working within these governments are programs honestly designed to make the nation, as well as the world, a better place while at the same time operating alongside programs designed to enhance and broaden the scope of power for individual elites as well as the nation. So, a conspiracy theorist neglects to believe the good that is very real and their perspective lacks balance because it lacks the entire truth.

You see, cynicism is like a cancer. Once a person gets into that negative mindset, cynicism grows. At first Frank believes that his coworker, Joe, who got a promotion, somehow conspired to sabotage Frank’s chances at the promotion by telling tales behind his back. Once Frank convinces himself of this truth, rather than the real, ugly truth that he’s just a lousy worker unworthy of the promotion, Frank then has to include his other co-workers in the conspiracy when they object to his accusations against Joe. As Frank continues to stew in his own angry juices he soon believes it all started at the top with a boss who must surely hate him. Eventually he either quits or his behavior is so affected he gets fired. Such an experience will most certainly shape his behavior as he continues on to his next job.

Rather than accept the uncomfortable truth that another person excelled his own capabilities and deserved the promotion, rather than believe the nasty truth about self, that he scapegoated a co-worker and then blamed his other co-workers and, ultimately, his boss, rather than accept that he is the problem, Frank continues in blaming others because that is more convenient than believing an uncomfortable truth about self. By perpetuating this scapegoat mindset Frank becomes unfit for any job. As he continues this self-destructive cycle blaming others rather than practicing self-accountability, Frank must then begin to believe in a united business conspiracy of a network of people who just want to keep him down. Eventually this unreasonable paranoia will affect Frank’s view of pretty much everything in his life.

Eventually, Frank is just a very nasty, negative fellow who believes that everyone is out to get him. He concludes if that’s true about society and work environments, it’s not a stretch to then believe that the federal government also conspires against the little people for their own gain. Mainstream and official sources of information are rejected as “tainted” and Frank only relies on fringe journalism because those are the folks who really know what’s going on and haven’t sold their souls to the “establishment”.  Eventually, by his own selective exposure to views that agree with his personal angry-at-the-world perspective, Frank is a full-fledged conspiracy theorist, brainwashed by himself.

So, when you get right down to it, psychologists are right. Conspiracy theorists are not really mentally ill. They are really just Negative Nellies and Nasty Nelsons. It’s perfectly fine to be a Curious Casper and entertain conspiracy theories for entertainment value or as alternative possibilities to an accepted truth that does not have the evidence to completely prove it to be the truth. But keep things in perspective. Don’t be like Frank.

Lost, Squished or Spaghettified By A Black Hole


Imagine you are zipping through the Milky Way in your spaceship, minding your own business, studying the stars, negotiating interplanetary alliances with interesting alien species, when all of a sudden alarms start sounding all over the ship. The helmsman is shouting, “Black hole dead ahead!” Everyone freezes in their tracks as a sense of doom overwhelms even the strongest survival instinct. After all, it’s a black hole, it’s a death sentence. Momentarily the ship will be caught in the great space suck, swirling down a cosmic drain to be crushed into stardust. Or not.

A proximity alert sounding through a spaceship is not the death knell as an iceberg was for the Titanic. New research gives space explorers some hope against the fated doom of a galactic squish. Rather than flat as a pancake, hapless star travelers would become space spaghetti, sucked into the black hole’s infinitely dense center and shredded. So, no, not the doom of a great space suck ultimately ending in pulverization, but a ghastly doom nevertheless. How in the world do scientists consider this good news?

The greatest physicist of all time, Stephen Hawking, has been telling everyone they were all wrong about what would happen if a person got sucked inside a black hole. The gringa is certain he must feel very satisfied to know that the rest of the scientific community has finally caught up with his genius.

And, although spaghettification sounds like a miserable end, scientists say that the good news lies in the fact that little bits of a person may be able to escape a black hole. But, again, this good news really isn’t good news at all. The only way a bit of a human might escape the black hole is if that particular bit of human spaghetti is converted into radiation.

But there’s one more kicker and opportunity for some actual good news. There are two types of black holes, one is stationary and the other spins like a top. In a spaceship trapped by a black hole scenario, hope for the spinning one. You may just be able to survive without becoming a glow-in-the-dark noodle.

If caught in a spinning black hole, also called a Kerr black hole, objects don’t necessarily get smashed to smithereens by gravitational increases. What experts expect happens is that the black hole’s gravity increases to the point of infinity. This happens so fast that the object passing through the black hole’s center remains intact.

So, this is great news. A crew and their ship could just zip right through a Kerr black hole unscathed, perhaps a little dizzy but not smashed or shredded. Then there’s the but. It’s very possible they could come out the other end in another universe altogether, once again doomed to an agonizing slow death of privation.

The gringa can only say, “Aaaarrrrgggghhhh! Please stop getting my hopes up then spaghettifying them with these darn good news/bad news scenarios. Just quit saying ‘good news’ altogether!” Because, guess what? The black hole business only gets scarier!

Scientists don’t know how they form. They are a mystery and can just, POOF, appear. So, even if humans do get some Galaxy class ships airborne, we better make darn sure we have some serious back up supplies on board because they could all get sucked to infinity and beyond no matter how clever we map their routes throughout the cosmos.

Who’s In For A 2-Month Long, Melanoma-Free Day?


As researchers plot their space plans to discover where possibilities lie for a home planet like Earth, that might even be supporting our ancestors, where are they looking? MIT astronomers comprising an international team in Belgium are plotting for a search about 40 light years away. That means if we don’t want a spaceship to arrive with astronauts dead of old age or perhaps affected by age-related dementia, we have to send astronauts in the age group of 20s-40s to manage the forty year flight mission. It may take another decade or two for space agencies to have the ability to travel that far so elementary and middle school children of today are the astronauts of tomorrow that may be slated for just such a mission.

Beyond our solar system is the best bet for finding life like our own, or at least a few planets like ours. An MIT team has discovered three planets that orbit a dwarf star about 40 light years away. Their sizes are about the same as Earth or Venus. The telescope the astronomy used to locate them is the TRAPPIST telescope located in Chile. This telescope is designed to specifically focus on a cluster of dwarf stars, 60 in number.  Belgian scientists created TRAPPIST to study the infrared wavelengths of dwarf stars and the planets surrounding them.

The scientist’s favorite dwarf star is an ultracool (as in thermally ultracool, not socially hip) star about the size of Jupiter and much cooler than our own sun. Beginning a period of observation in September, 2015, the astronomy team observed regular intervals of fading in the infrared signature of the star. They theorized that planets were passing in front of the star causing this to occur.

The team turned their attention to the time to expect a light fade event and discovered that there were, indeed, planets orbiting the star. The two nearest planets were similar in size to our own Earth and Venus. The closest planet that has everyone’s attention is named 2MASS J23062928-0502285, commonly called TRAPPIST-1. The two planets have orbit cycles, respectively, of 1.5 of our own days and 2.4 days. The amount of radiation they absorb from their star is significantly more than what we deal with. The closest one receives about four times the radiation we get and the next one about two times the amount. So, if there is any life there it would have to have evolved with natural radiation tolerance.

The third planet in distance from the star has an unknown orbit cycle. The scientists’ best guess so far is that it could be anywhere from four to 73 days but would receive significantly less radiation. I guess that’s good news. If we need to relocate I suppose we could deal with a four-day long day or even a two-month long day and not have to worry about skin cancer.

When the team analyzes the size of the planets in relation to the star, and take into account their proximity to their sun, they believe that life could be sustainable. They calculate that there could be areas with a temperature range less than 400 kelvins. That converts to about 260 degrees Fahrenheit or 127 degrees Celsius. Not exactly a tropical paradise but conditions where liquid water and organic life could survive.

The next step is to study the atmospheric conditions of the planets to see what their atmospheres are composed of. What kind of gases? Is there breathable oxygen? And they believe that within their own working career’s lifetime they will be able to determine if these planets are inhabited with life of some kind, say the next ten years or so.

This is a breakthrough in science. Traditionally scientists have studied bright solar stars like our own. By taking a risk and searching for a cool dwarf star, this MIT group has hit paydirt with the find of a lifetime. To accomplish their task they had to design a whole new set of instruments specialized to detect the radiation emitted by cold dwarf stars and only visible through an infrared telescope. The whole field of detecting other worlds changed simply by changing the wavelength humans were viewing the galaxy with. Perspective is everything.

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.

Say Hello to R2 aka Hardhat Harry


Robonaut. It sounds like the title of a cheap sci-fi flick or perhaps the name of a second-rate children’s superhero action toy. In reality, Robonaut, Robonaut 2 (R2), to be exact, is a vital part of the crew aboard the International Space Station. He is a humanoid robot the gringa likes to call “Hardhat Harry” because of the types of jobs he performs as well as the future plans NASA is cooking up for him and future Hardhat Harry clones.

Presently Hardhat Harry is going through his paces as NASA engineers study how well he performs at this job. NASA hopes that one day Hardhat Harry will be able to join astronauts in their dangerous and risky spacewalks when they perform the necessary maintenance and repairs required on the outside of the space station.

But Hardhat Harry is more than just a handyman, he is also a scientist. In the Destiny laboratory he takes velocity air measurements. However, he is not above giving handrails a good scrubbing. And, just like the gringa, Hardhat Harry likes to flip switches and push buttons.

Guess how he performs his duties? Does the dear reader envision a programmer sitting in front of a computer screen inputting commands? Perhaps an image flashes through your mind of something like a video game with an engineer using a joystick to maneuver Hardhat Harry through his tasks. Nope, it’s even cooler than that. Crew members on board the ISS get to play a very serious scientific game of virtual reality, donning virtual reality headgear and controlling Hardhat Harry as if he were themselves!

Although Hardhat Harry has plenty of charm, don’t fall in love yet. Don’t get any ideas of thinking you will be able to visit one of the many space centers around the world when he returns from his mission and get his autograph. NASA has no plans for Hardhat Harry to ever return home.

Hardhat Harry will continue to be improved and upgraded as researchers learn how to adapt the technology to perform in the vacuum of space and eventually embark on deep space missions. Fleets of R2 Hardhat Harry clones will become the world’s future hi-tech repairmen, traveling far and wide to repair and upgrade communications and weather satellites. There is also great hope that a Hardhat Harry crew will be developed and shipped off to Mars for a surface mission or mine geological resources from the Moon.

Hardhat Harry and his kin will not replace astronauts, so, dear readers, if you are an astronaut hopeful like the gringa there is no need to despair. R2s are simply going to go first and make the way safer for exploration. And, by performing the boring repair jobs, astronauts can devote more time to discovery.

The next phase of progress is to deliver Hardhat Harry some legs. It may seem kind of silly to have Hardhat Harry up there, trying to get the job done without any legs, but remember, he is working in microgravity. He doesn’t necessarily need legs to move about the ISS. And, the legs they will be sending him don’t even have feet. They have grasping contraptions at the end of his “legs” that will secure him to railings while he works.

And, by having removable legs, Hardhat Harry has the option to rove about planetary surfaces centaur style. NASA is developing a four-wheel vehicle that Hardhat Harry’s torso can attach to as he zips about the Moon or Mars or wherever his adventures take him or NASA needs him.

Fans of R2 (aka Hardhat Harry) can keep up with all his exploits in space via Twitter @AstroRobonaut. So, for all the gringa’s dear readers who love robots and have great big dreams and ambitions with robotic technologies, keep your dreams alive and see if NASA can help you make them come true!
