Poopbots Running Amok In The Muck


Yes, dear reader, you read the gringa’s post title correctly, poopbots. And they are literally running amok in Boston’s subterranean muck. Mario and Luigi are pioneering waste miners delving the stinky depths of Boston’s sewers. They are gathering data from human effluence for epidemiologists so they can uncover even darker secrets of human health and behavior. So what does the future of poop collection and dissection look like?

MIT researchers involved in Senseable City Lab’s project, aptly named Underworlds, are on a mission to help scientists predict outbreaks of dangerous and deadly diseases. They also want to help discover some of the causes of chronic diseases whose origins in human health remain a mystery. And they believe clues to solving these mysteries lie deep in the sewers, secreted in what’s been excreted.

Project leader, Carlo Ratti, uses the example of influenza to explain. Before a widespread outbreak is evident in local hospitals, the virus could have already been detected in the human waste produced by those first afflicted. Once a city makes poop monitoring a regular thing, they can isolate and respond to any outbreak much more rapidly. Hopefully, future widespread epidemics can be prevented.

Mario and Luigi scan for industrial toxins, human biomarkers, and other chemicals related to contagious disease and chronic illnesses such as diabetes. It’s kind of like an urban poop census. The Environmental Protection Agency is completely on board with the idea of an urban poop census. They see this ambitious project as the latest advance in an inexpensive way to monitor public health in a timely manner that is relevant. The gringa believes that EPA agents are probably just glad to say good-bye to the days of scooping poop to fill their sample quotas.

Luigi and Mario are controlled remotely and use a GPS system to navigate. Within fifteen minutes of a flush, a fresh sample can be collected. By gathering samples so soon after a dump event scientists can determine the difference between chemicals a person is exposed to as opposed to chemicals a person ingested. The most common food products found in human waste thus far in the project are rice, wheat and beans. However, the occasional pomegranate seed collection makes for a nice surprise.

If the underworld of human poop analysis by robots interests you, Underworlds has its own website. Interested poop fans can gaze in wonder as data is disseminated to reveal what types of viruses are in the local water supply right alongside any bacteria or chemicals. If all goes well with Mario and Luigi, the state of Massachusetts may expand their poop inspection territory. The gringa suspects this will, indeed, be the case considering that even Kuwaiti poopers have been so impressed they have implemented their own poopbots in partnership with Underworlds.

Although MIT has long been heralded for the many scientists and engineers and mathematical geniuses who have graduated there, now, it will forever be remembered as the institute of poop pioneers. Better a pioneer than just a lowly pile, is what the gringa says!

A One Way Ticket To Tomorrow – Time Travel


Ever really screwed things up and wanted a do-over? Yeah, the gringa does that all the time. That’s what makes time travel so appealing. But is it possible? Theoretically, sure it’s possible, but only if you want to see the future. To start the day all over again in order to get it right the second time around means travelling faster than light and that, theoretically, is impossible. But, actually, that’s good news. That means a spiteful ex can’t travel back in time and take out your grandfather, thus wiping out your future existence. It also means that adventurers who travel to the future have to stay there (maybe). For a trip to tomorrow, it’s actually relatively easy, according to scientific formulas (although no one’s actually done it yet, I think).

You see, if a person hopped on board their spaceship and zipped away into the cosmos at even a fraction of lightspeed, for a journey of say a year or two, they would return to an Earth that had aged perhaps by decades. So, technically, the galactic pioneers traveled to the future. But Einstein offered another option to travel to the future in the blink of an eye, wormholes.

A wormhole is a time tunnel that connects different parts of the universe. By using the wormhole as a direct route across the universe, rather than taking the long route of flying through the curved mass of space, a person would emerge, within moments, in a completely different time zone, perhaps an entire era altogether, hundreds of years in the future. The furthest a person could then go back in time would be to simply use the wormhole to return to the point they started from. However, a Caltech physicist by the name of Kip Thorne believes that quantum theory suggests that once a person traveled through a wormhole it would collapse behind them. A wormhole to the future might be a one way ticket to tomorrow.

So, if you want to have a time traveling adventure, you just have to find a wormhole. Or go to China. Yep. That’s what the gringa said. Go to China. Interesting reports have been in the news for a few years now about a time travel tunnel in China. Located in Guizhou Province, time travelers can break all the rules and travel back in time. You don’t even need a spaceship. You can use the ancient technology of cars.

It only takes, technically, about five minutes to travel the 400 meter length of the tunnel. However, when drivers emerge on the other side of the tunnel their electronic devices indicate that they have traveled back in time about one hour. However, time is a jealous mistress. It seems to not appreciate being lost and chases down evaders like a jilted lover turned crazed stalker. Once people travel some distance from the tunnel their lost hour catches up with them.

What the heck is happening here? It’s a mystery. One that is absolutely adored by science fiction fans, conspiracy theorists and alien abduction proponents. However, China is not a fan of wacky explanations. They have offered a few boring theories as to why this is happening:

  • A transmitter in the tunnel is resetting everyone’s electronic clocks which reset once again when they receive new GPS signals from a different transmitter after emerging from the tunnel.
  • A localized magnetic anomaly messing about with electronic devices

The gringa doesn’t really care why. It seems harmless and loads of fun. The gringa would like to go back and forth several times, perhaps hundreds of times, maybe thousands just to see what might happen. Maybe I’ll lose a wrinkle or two.

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.

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)
  • Mariner 5 (1967)
  • Pioneer 5, 6, 7, 8, & 9 (1966-1969)
  • S-IVB upper stage panels of Apollo 8 (1968)
  • S-IVB upper stage panels of Apollo 10, 11 & 12, & #10s ascent stage panel LM Snoopy (1969)
  • Mariner 6 & 7 (1969)
  • Mariner 10 & Mercury (1974, 1975)
  • Mars Observer (1992)
  • CONTOUR (2002)
  • Genesis, Spitzer Space Telescope, Kepler Telescope, STEREO-A & STEREO-B

Russian Space Junk

  • Luna 1 (1959)
  • Venera 1 (1961)
  • Mars 1 (1962)
  • Zond 2 (1964)
  • Zond 3 (1965)
  • Venera 2 (1966)
  • Mars 4, 6 & 7 (1974)
  • Venera 11 & 12 cruise stage (1978)
  • Venera 13 & 14 cruise stage (1982)
  • Vega 1 & 2 (1984-1986)
  • Phobos 1 (1988)

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.

A Happy, Hopeful Astronaut


The gringa is happy to announce that she is one step closer to realizing her astronaut dreams! The media has given so much attention to SpaceX and their contractual relationship with NASA that the wonders of Blue Origin have not received their due. And, for aspiring astronauts like myself, this is a terrible injustice that the gringa hopes to rectify with this humble blog post.

Blue Origin is making it possible for astronaut hopefuls to reach dizzying heights above the Earth. Space pioneers will soon launch into Earth’s atmosphere in the New Shepard capsule that is perched above a sixty foot rocket that has proven its re-useable capabilities long before SpaceX claimed such fame. They had successful launches and landings November, 2015, and this month, January, 2016.

The New Shepard can sit a six man crew and accelerate past 3G’s, that’s faster than Mach 3. And, although each crewman does have duties aboard ship, there is plenty of time for space explorers to kick back and gaze out some enormous windows upon the vastness of outer space that surrounds our beautiful planet. Once the New Shepard capsule separates from the rocket booster, passengers then experience weightlessness in the perfect stillness of the vacuum of space.

Where does all of this amazingness happen? Practically in the gringa’s back yard, right here in Texas, west Texas to be more exact. Very soon Flyboys and Flygirls will begin arriving at the launch site and go through a two day training course on what to expect as well as what your astronaut responsibilities will be. There are flight simulations, safety briefings and in-depth flight training on procedures, communications and maneuvering.

Launch day starts at sunrise for pre-flight checks and final clearance. Once the go ahead is given, space explorers climb in, batten down the hatch, strap in, and COUNT DOWN. The launch is a 150 second burn of the ride of your life! In no time the blue sky fades to black, yeah, just like the Metallica song. Astronauts get to explore the weightlessness of zero gravity, contemplate man’s place in the Universe, and make spaceflight history.

Earthbound mission control will signal when it’s time to get your feet back on the ground. So, strap back in and be prepared for an even faster trip back down (over 5Gs!) that will be slowed by eight drag brakes (technical-speak for parachutes). Right before touch down the rocket engine fires up and slows the booster for a 5 mph landing very close to the launch area.

Blue Origin’s motto is “Gradatim Ferociter” which is Latin for “step by step, ferociously”. Step by step they have built upon one success after another and broken new ground in the spaceflight industry. They are making it possible for EVERYONE (that has enough money, that is) to be an astronaut. In fact, Blue Origin wants to make it possible for millions of people to eventually live and work in outer space.

Although SpaceX has gotten more media attention for building a reusable rocket system, Blue Origin experienced this success first. With each flight, the cost of spaceflight becomes more and more affordable. Maybe it will be within the gringa’s budget in another five or ten years. Who knows?! But, one day, I’m going!

Blue Origin is perfecting their New Shepard flight program with ongoing tests of unmanned test flights. They have yet to put a crew up into the heavens. But, each test brings the day closer when astronauts like you and I, dear reader, will climb on board and make history!

And, if you’re not interested in getting shot up into the sky, you can still be a part of history by working for Blue Origin because they need lots of folks with skills! Just a few slots they need to fill:  Aerodynamics Engineer, Aerospace Technician, Avionics Engineer,  Avionics Software Development Engineer, Composite Structural Engineer, Dimensional Inspector, Director of Safety and Mission Assurance,  Dynamic & Loads Engineer, HelpDesk Technician, and the list goes on and on.

And you don’t have to necessarily relocate to West Texas to have one of these fantastic jobs. Blue Origin has facilities in Washington State and Florida, too. So, if you believe in no limits, are passionate about the space industry, and have something to offer to Blue Origin’s collaborative efforts, you need to check them out.
