Sun Worship


Earlier this month celestial lovers throughout south and central Africa got to enjoy a spectacular solar eclipse that produced a ring of fire as the Moon transversed across the pathway of the Sun. The peculiar occasions when the Earth, Moon and Sun all line up together doesn’t happen too often. Such a rare event has historically been linked with all sorts of predictions and paranormal expectations.

The funniest recording of a solar eclipse is, perhaps, also the earliest record. Occuring in October of the 2137 B.C., two royal astronomers, Ho and Hi, offended the fourth Emperor of China’s Hsia Dynasty,  Chung-K’ang. The eclipse was an unexpected event. The poor astronomers were unprepared to perform the customary rituals that should have taken place. The pair of official stargazers were drunk and failed to launch the traditional arrows and beat out the right rhythm on the gongs and drums so that the Sun could be delivered from the mythical beast that was attempting to devour it.

Convinced that chaos would soon consume the empire, the astronomers were summarily executed as an appeasement sacrifice for their drunken dereliction of duty.  A public record of their death was translated in 1839 by scholars to reveal an amusing verse indicating that, although brutal in enforcing their expectations, the ancient Chinese did have a sense of humor:

“Here lie the bodies of Ho and Hi,

Whose fate though sad was visible –

Being hanged because they could not spy

Th’ eclipse which was invisible.”

In November of the year 569 an eclipse was recorded before the birth of the Prophet Mohammad in 570. There are many religious historians who link this eclipse as the moment of Mohammad’s conception. Interestingly enough Mohammed’s son Ibrahim died at the age of two-years-old during the occurrence of a solar eclipse. Mohammed wrote of this event as a sign sent from his God, Allah, of personal condolences. Muslims today still consider eclipses significant religious events. When the recent eclipse occurred mosques throughout Africa had special calls to prayer for safety and deliverance from harm.

Perhaps the most significant solar eclipse in modern history is the one of May, 1919. Commonly called “Einstein’s Eclipse”, it is considered to be the solar eclipse that changed the universe. For more than 200 years scientists had accepted Isaac Newton’s principle that the space of the Universe was as inflexible as mathematical principles.  Einstein set out to challenge this longheld belief. Einstein believed gravity was curved and flexible, affected by the mass of planetary bodies. He proposed that warping of space allowed planets to remain in their orbital paths, gravity distorted by the mass of a celestial body, the greater the mass, the stronger the force, which would result in more bending of light. This was to become known as Einstein’s Theory of Relativity.

When the 1919 eclipse occurred, British astrophysicist Sir Arthur Stanley Eddington led the charge for an experiment to take advantage of the expected eclipse. Eddington traveled to Principe which is in the Gulf of Guinea off of Africa’s western coastline. A horrible thunderstorm threatened to ruin Eddington’s chances but, fortunately, by afternoon the skies had cleared. Eddington’s celestial photographs and measurements were compared with photos and measurements recorded by Andrew  Crommelin at the Royal Observatory at Greenwich. The findings were announced by Britain’s Royal Society’s Astronomer Royal Sir Frank Watson Dyson. It was announced in London on November 6, 1919 that Newton’s theory had been disproven by Einstein’s new Theory of Relativity.

To make sure that you are ready for the next opportunity to view a solar eclipse, log on to www.timeanddate.com and keep a watch on the countdown clock for eclipses listed under their Sun & Moon tab. It seems we are only about 5 months away from the next big event.  There is a handy search window everyone can use to see if their city or country is going to be in the most fortunate position of being able to see the eclipse.

To view a solar eclipse it is important to wear protective eyewear. A homemade viewbox can also be created called a pinhole camera. All you need is a box with a small hole on one side for light to pass through and project an inverted image of the eclipse on the opposite side.  Below is a video with an example of how to make and use a homemade pinhole camera. One tip: The bigger the box the better the view.

The Truth About Tabby


UFO and alien conspiracy theory buffs are going to enjoy this post by the gringa, or not. I guess it depends on if you enjoy a healthy dose of conspiracy debunking or truth. You see, dear readers, there has been a bit of hubbub about an interesting space object that is orbiting a nearby star and was detected by the Kepler telescope late last year.

The SETI Institute (Search For Extraterrestrial Intelligence) calls KIC 8462852 “mysterious”. NASA believes the mystery is resolved with the theory that the strange signals are the result of cosmic dust, probably from multiple impacts of a comet swarm, and causes the star’s light to flicker erratically. Vanderbilt University researchers, who affectionately call the star Tabby, debunk theories by those who believe it to be home of aliens who are very, very busy. The astrophysicist contributors to the respectable Astrophysical Journal agree with Vanderbilt’s point of view while at the same time agreeing with theories from other scientists who propose an extraterrestrial origin theory. So, who’s got it right? Who’s got it wrong? Just what the heck is the truth about Tabby?

Who Is Tabby

Tabby is officially designated star KIC 8462852 and shines brighter than our own Sun about 1400 light years from Earth in the Cygnus constellation. It is a subject of study by NASA’s Kepler space telescope which reveals that from time to time it dims about twenty percent in brightness.

SETI’s Conclusion

The cause of the dimming light could possibly be because of material or objects orbiting the star. SETI researchers believe they have evidence to determine that these objects are not planets. SETI considers the possibility that Tabby could be home to a technologically sophisticated society that has constructed a swarm of solar panels that orbit the star which would account for the light fluctuations.

SETI uses its own Allen Telescope Array to study radio signals that originate from that part of outer space. They attest that these radio signals are of artificial origin, calling them “non-natural”. They search for narrow-band signals and broadband that might possibly be produced by a large and powerful spacecraft. They also search for evidence of laser pulses. SETI’s Panamanian partner, Boquete Optical SETI Observatory, performs the laser pulse research.

Research such as this takes a long time so the gringa will have to practice patience for SETI to conclude their studies and publish their final results. They admit that, historically, cases like this usually result in finding a natural cause for the anomalies but they still must investigate the possibility of it originating from extraterrestrial intelligence. That is, after all, their mission.

NASA’s Conclusion

During four years of observation, the Kepler mission recorded strange happenings in 2011 and 2013 when interesting and dramatic light fluctuations occurred. To help determine what happened, NASA also trained the eye of the Spitzer Space Telescope in Tabby’s direction. Kepler observed the visible light. Spitzer could delve deeper into the invisible infrared light signals and patterns. In November of last year Spitzer paid off with a recording of another light fluctuation.

Although NASA’s theory is that clouds of space dust were formed from a swarm of comets that orbit the star in erratic patterns, Spitzer did not discover evidence to support this theory. This caused NASA to switch to a cold comet theory. One lead comet would be followed by a swarm of smaller comets. If this is true, even if the comets were already out of the telescope’s view as they traveled around Tabby, they should still leave behind a detectable infrared signature. However, this was not the case.

Researchers admit that more observations need to be recorded to determine just exactly what is going on. NASA admits that Tabby is strange, indeed. However, they believe that a natural cause is more likely than “little green men”.

Vanderbilt University’s Conclusion

Vanderbilt studies focused on the 100 day period when the most significant light fluctuations occurred. The manner in which they occurred suggested that a large number of “irregularly shaped objects” passed in front of the star causing its light to be blocked temporarily. Working off a report from an astronomer at Louisiana State University who concluded that the star had diminished in brightness by 20 percent over the past century, Vanderbilt finds a natural cause unlikely as an explanation for this. This has become fodder for the theory that a megastructure has been constructed that is absorbing the star’s energy, the solar panel array theory. This is a theory that was reviewed, accepted and published by the Astrophysical Journal.

Vanderbilt, however, did not stop there. They soldiered on. Partnering with amateur German astronomer, Michael Hippke and NASA scientist Daniel Angerhausen, the team began comparing the 20 percent drop in intensity to other stars. They discovered that this is not an unusual phenomenon. In fact, it’s not a star phenomenon at all. It is simply the result of technological changes and advances of human manufactured instrumentation for observance.

The Gringa’s Conclusion

These are all interesting theories but not yet solid answers. So, the gringa will wait and see if, ten or twenty years down the road, we all find out what the actual, final answer is:

  • Comet Swarms

or

  • Extraterrestrial Solar Array

Until then, Tabby will be the most interesting and mysterious star in our night sky.

Isaac Newton By The Sea


NASA recently reported images of an X-ray tail (or, ribbon) of galactic gas. It has broken cosmic records with the extraordinary length of 250,000 light years. The published images are a composite from combined data that originated from the Chandra orbiting observatory and the Isaac Newton Group (ING) of Telescopes that are located in the Canary Islands of Spain.

ING consists of two telescopes. One is named William Herschel (WMT) and the other is Isaac Newton (INT). They are located on a seaside cliff of La Palma Island and command a breathtaking view of the sea as well as the night sky. Isaac Newton began serving astronomers in 1984 and William Hershel in 1987.

ING is a collaborative effort of scientists representing the United Kingdom, the Netherlands and Spain. Their goals in serving the world community of astronomers and space related science is to provide world class telescope operations and programs that aid in research efforts. To encourage innovative methods in science and research, ING welcomes projects that involve novel instruments as “visitors”.  ING is committed to fostering original thinking as well as strongly supporting classical observing.

The Isaac Newton Telescope is open for visiting observers. New instruments are now being enjoyed with funding to provide more. One new instrument, the PAUCam, is a state of the art imaging device that creates prime focus capabilities for the William Hershel Telescope. A wide-field multi-object spectrograph is being developed for William Hershel and expected to become operational in 2017. This instrument will be part of a five year study to help understand how the Milky Way was “assembled”.

WEAVE is the name of the spectrograph developed for William Hershel. WEAVE was designed and built by a consortium of institutes from the UK, the Netherlands, Spain and France. Although visitors will still have access to observe the heavens through William Hershel, much of the telescope’s time will be devoted to the study of three particular projects: 1. The archaeology of the Milky Way; 2. The evolution of the galaxy; 3. Dark energy and its nature. These projects create wonderful opportunities for the UK, the Netherlands and Spain to make important scientific contributions to the world community’s knowledge of outer space.

Resident student programmes are available with ING. Over the past decade, forty students have served in the position of INT support astronomers and have gained valuable hands-on experience and technical skills. In fact, since 2009, 53 PhD theses have been based on ING data. Announcements will be made in March 2016 about the details of the 2016/2017 programme which offers astronomy and astrophysics PhD’s, MSc’s. INT welcomes students who are interested in any field of astronomy or astronomical instrumentation.

Students stay in flats provided by ING and receive a modest monthly stipend. These are cozy abodes within walking distance to the observatories, however, ING also provides transportation back and forth. For one year students will have the opportunity to participate in supportive roles in the work performed by one of the world’s most scientifically productive and versatile telescope groups. They will become part of the professional astronomical family of La Palma.

To qualify for admission to the programme, students must be a European citizen or European student resident. Enrollment in an astronomy PhD or MSc program or in the final year of undergraduate astronomy or physics course is required. English is a must, Spanish is a plus. It is also helpful to have some experience with Linux/UNIX operating systems as well as IRAF astronomical data reduction software. While participating in the program, expect to work 37 hours weekly, day or night, as well as weekends and holidays. A valid driving license is expected as well as being able to pass a medical examination.

Four positions are available. Students report for duty in September. During the one year of service, students have a 25 day leave allowance.

Qualified students who are interested should prepare a cover letter presenting experience along with any other pertinent information to be considered. Two references are required. Applications must be received by May 1 via e-mail or snail-mail. E-mail contact is Ovidiu Vaduvescu, INT studentship program manager, ovidiuv@ing.iac.es. Snail mail contact info:

And, if you are unqualified, like the gringa, but still interested in what goes on at ING, their website has an interesting feature that the gringa really likes. It’s called “Ask an Astronomer!”. You simply fill out the e-mail form and submit. It’s not just any ol’ email form, however. It also has lots of other information to pick and choose from. Click “send” and wait for an amazing scientist to school you on what you want to know.

Chandra & the Jellyfish


IC 443 is more commonly known as the Jellyfish Nebula. What the heck is a nebula? Well, a nebula is a cloud of dust and gas found in outer space. Sometimes, at night, if you find yourself in the perfect spot for stargazing, you may notice a spot in the sky that is brighter or, perhaps, a darker shadow across a brighter patch.

The Jellyfish Nebula is thought to be the gas and dust leftovers of a supernova event that happened in outer space about 5,000 light years from planet Earth. What the heck is a supernova? Sometimes a star suddenly becomes much brighter because of great explosions happening within the gas that it is made up of. When it becomes so explosive and heated that it ejects most of its mass, it has gone supernova. So, in the simplest of terms, a supernova is a star that has exploded BIG TIME.

The gas and dust debris of the Jellyfish Nebula may also be the material that created a strange object found due south of the nebula. This object is officially called CXOU J061705.3+222127. Scientists just call it J0617. These same scientists believe this object to be a pulsar. What the heck is a pulsar? A pulsar is a neutron star that is rapidly spinning around. It also emits pulses of radio waves and electromagnetic radiation.

What the heck is a neutron star? A neutron star usually has a radius less than 18 miles but is densely packed with neutrons. They are most often created when a massive star goes supernova and leaves behind its core. As a massive star runs out of fuel the stage is set for a supernova explosion. When the fuel runs out, the outer layers collapse. When these outer layers come into contact with the core, they then bounce outward creating the supernova explosion. In the end, all that’s left is the core which is now spinning like crazy and emitting pulses of radio waves and radiation.

The post photo of the Jellyfish Nebula has an inset that shows the region surrounding J0617. Scientists are interested in the small ring that appears to surround the pulsar. There is also a feature of something jet-like that passes through the pulsar. The scientists want to determine if this emission is directly related to the pulsar or has a different source. Possibilities are a high speed wind of particles or something like a shock wave.

Nothing definitive has been concluded regarding when the supernova event occurred. Researchers have offered estimates ranging from 3,000 years ago to 30,000 years ago. Needless to say, the scientists have much more to learn about the Jellyfish Nebula and J0617. If the dear reader is interested in more details than what the simple-minded gringa can offer, check out the on-line source “The Astrophysical Journal”.

Research on the Jellyfish Nebula is managed by NASA’s Chandra program. Specifically, Chandra is an X-ray Observatory. It is the most powerful orbiting X-ray telescope in the world. Scientists from all over the world have access to the images generated by this program. The gringa loves how NASA likes to share knowledge and is not stingy with their technology.

Chandra studies cosmic X-rays, or, the effects of matter that has been heated to millions of degrees. High temperatures that create detectable X-rays happen throughout the universe wherever there are strong magnetic fields, powerful forces of gravity, or extreme explosions (like a supernova).

When a supernova happens, charged particles slam into one another. This causes them to produce energy in the form of photons. As photons fly through space, leaving the scene of a supernova event, they actually become light. These are just the sorts of things Chandra has been tracking and recording since 1999 when the Space Shuttle Columbia launched Chandra into outer space.

Chandra has eight mirrors that X-rays slam into, ricochet off, and are focused onto a focal plane that is half as wide as a human hair.  The focal plane captures the image of the X-rays and records the number, position, energy and arrival time. Two spectrometers then analyze the X-ray to determine what form of energy it is and other details of its physical condition.

Chandra is housed in a spacecraft observatory with two sets of thrusters. This observatory was the largest and heaviest payload ever launched by a Space Shuttle, weighing in at liftoff at 50,162 pounds. If you had eyes as powerful as Chandra, you could read a stop sign from twelve miles away. Chandra’s mission duration was originally set for five years. The mission began in August of 1999 and she is still going strong.

“Back Up Life…”


SpaceX is the private company that is contracted with NASA to supply the space agency with the “Dragon”, a crew transport spacecraft designed for large crew capabilities as well as deep space missions. Elon Musk, the creator of SpaceX, recently gave an interview with GQ magazine. In that interview he voiced his concerns regarding accomplishing the Mars mission in light of the fact that this world’s nations just can’t seem to grow up and stop all of this war mess.

Musk’s big dream is to colonize Mars. Considering his accomplishments, the gringa believes he can achieve his dream. I mean, just think about it: he leads a company that has managed to develop technology that can design and build rockets at a fraction of the cost as NASA. SpaceX is also the first private company, ever, in all of the world, to have launched a spacecraft into orbit and have it successfully return to Earth. SpaceX has impressed NASA so much that it is contracted to manage resupply missions to the International Space Station as well as transport the astronauts between the ISS and Earth.

Musk believes colonizing Mars is more than just a glamorous adventure. He believes this mission is critical to the ultimate survival of the human species. Considering how mankind has been consistently annihilating one another since a caveman first created a club to sock it to his romantic rival, the gringa has no trouble at all believing Musk’s worst-case scenario of a natural or man-made disaster destroying life as we know it on Earth and the survivors starting over somewhere else. Why not Mars? Musk’s philosophy can be summed up in this statement, “You back up your hard drive… Maybe we should back up life, too?”

In addition to reusable rocket technology and personnel space ferries, SpaceX is developing “Mars colonial transport architecture” to further advance toward the ultimate goal. The gringa asks, “What the heck is that?”

A critical piece of this architecture is commonly called the BFR rocket (it has a technical name but Musk and the developers refer to it as BFR). Now, the gringa likes to keep things family friendly on these blog posts, but, just so you know, BFR actually stands for Big F*#@ing Rocket. I MEAN IT! No kidding! I love that! Scientists that have a sense of humor are right up the gringa’s alley.

The BFR is a two part rocket, booster rocket + spaceship. The booster is to break through the gravity and atmosphere of Earth. Once free, the spaceship is designed to travel through deep space to Mars. The gravity of Mars is weaker than Earth’s and also has a thinner atmosphere. Because of this the spaceship does not need a rocket booster to blast off from Mars for a return trip home.

In order for Martian colonists to create a self-sustaining environment on the Red Planet, what must be done? The planet has to be terraformed to create a warmer environment that will lead to ice melts so that it becomes a “watery” planet. Then fauna can be introduced that will help to create a breathable atmosphere. Musk considers Mars to be a “fixer-upper”. The gringa likes that term.

Nuclear energy could be used to help warm the planet. By converting technology that has been used to destroy life, the fusion bomb can be repurposed into technology that creates and sustains life (now, the gringa LOVES that!). As tiny pulsing suns at each Martian pole, this technology would create a warming effect without radiation and fallout. Mars would then experience the same benefits Earth has from its proximity to the Sun.

Now, NASA is devoted not only to preserving life on the planet Earth, but any life that may possibly be present throughout the cosmos. It has a Mars directive in place forbidding any mission landing near any area containing the potential for liquid water. That is because of the possibility of the presence of bio-organisms, life, causing cross-contamination, whether those organisms are of Earth and contaminate Mars or vice versa.

The good news, as far as the colonial mission goes, is that NASA’s research has not detected any life present on Mars, even on the microscopic level. So, if it is eventually determined that no life at all exists on Mars, the moral dilemma of invading, contaminating and/or destroying it is resolved and colonization can get the green light. The only life on Mars that might exist that NASA’s current research methods are unable to detect is subterranean microbial life.

So, who would like to give the pioneering life a shot and actually become a MARTIAN?  The gringa says, “Where’s the sign up sheet?”

Now, it’s pretty clear that Musk is the type of personality that is driven. There is very little that seems to get in his way when he has set a goal. His biggest concern regarding achievement of colonizing Mars is the very real reality of war. The Earth has never seen a single day in modern history where there has not been an active war somewhere. War could be the very thing that prevents progress.

War stood in the way of progress in the early 1900’s. It was supposed to be a golden era with no more war. Then, guess what? BAM! World War I started. Then World War II. Then the Cold War. However, the Cold War eventually led to the space race, so progress did come of that mess.

How possible is it, then, for progress toward colonizing Mars be disrupted? Pretty darn possible. So, the gringa says to all the religious zealots and war profiteering warmongers everywhere, “JUST STOP IT! KNOCK IT OFF! WE ARE SICK OF IT!”

Now, I know you must be itching to see just how much more fantastic Musk’s dream can get. Well, just check out his timetable. He is determined for all of this to be accomplished within his lifetime. If Musk gets his way (and he seems very apt at always getting his way) the world could see the first boots on the ground on Mars within the next ten to fifteen years.

In fact, before the end of 2015, or early in 2016, he plans to make a big announcement regarding his Mars-colonization plan. The gringa cannot wait to hear this crazy plan because I’m a crazy gringa who is his biggest fan!

The “Little Green Men” Star


If you happen to be a writer looking for fodder for a great science fiction story, you may want to delve into NASA reports regarding star KIC 8462852. NASA is fascinated by the strange goings on about this star and bears much resemblance to a pulsar named LGM-1 (Little Green Men). This pulsar emitted strange signals that created a stir within NASA and were ultimately determined to be a natural phenomenon. The strange events involving star KIC 8462852 have yet to solved.

Monitoring this star has been the responsibility of the Kepler mission for the past four years. In 2011, and later in 2013, two significant, and as yet unexplained, events took place. What do scientists really know? They know that the star dimmed because “something” passed in front of it large enough to block its light. The gringa says, “What the heck?”

In September scientists finally reported their theory and findings on what could possibly explain these strange events. They are blaming a “swarm” or “family” of comets. The gringa’s imagination begins whirling and thinks, “Or perhaps a fleet of starships.” Another theory suggests a cluster of planetary fragments and asteroids.

Scientists are using NASA’s Spitzer Space Telescope to probe deeper into this mystery. To learn more, scientists, who first studied the star using observations conducted in visible light, then tried using infrared light. This is because if asteroids were involved and actually impacted the star there will be a whole bunch of infrared light surrounding the star and the dusty old bits of gravel from a pulverized asteroid should be at the perfect temperature to glow like a firefly under infrared wavelengths.  And detecting infrared light is one of things the Spitzer Space Telescope is designed to do.

This year the Spitzer took a gander at star KIC 8462852 while looking at hundreds of thousands of stars in its search for planets. One thing in particular that Spitzer was looking for was infrared emission of space dust that encircled stars. Spitzer didn’t find any of this type of dust around star KIC 8462852 so scientists think the asteroid collision theory can probably be scratched.

So, the gringa wants to know just what their thinking is now. What the scientists seem to be leaning toward is the possibility of a “swarm” of cold comets. For such a theory to work, this cluster of comets would need to have an unusually long orbit around the star. They also call this theoretical comet cluster a “family” because it would require a “pack leader” to explain some of the phenomena. The larger “big daddy” that would be in the lead would have been the one to block the star’s light in 2011. In 2013 the rest of the family would have been passing through in front of the star and blocked the light again in the strange pattern that was recorded.  This would explain why in 2015, when Spitzer observed the star again, there were no infrared signatures. The comet “swarm” was long gone and probably around on the other side of the star in its orbit progression.

The gringa must confess to thinking, “Mm hmm. Scout ship shouts, ‘The coast is clear!’ and the support ships soon set a course for the coordinates.” Oh yes, what an imagination! But please don’t judge the gringa! I just couldn’t help myself when NASA itself goes and names a pulsar something like “Little Green Men-1”.

NASA admits that what is going on with this star is strange and not understood. Their interest is extremely piqued so study and research will continue until the curiosity of these scientists are satisfied. And I ask you, is that not the greatest job ever? For every little kid that has lain on their back in the grass in the dark of the night staring up at the stars and wondering if there really are “little green men” out there, is that not just the coolest job ever to grow up and get to do!

The Girl Who Loved To Count


And who says girls are bad at math? Most definitely Katherine Johnson is not!

Born in West Virgina in 1918, she was a girl who grew up in a time when not only were women not expected to grow up and do great things, but a woman of color had the additional obstacle of racism. But that didn’t stop Katherine from counting and that is the fascination that led to her greatness that culminated in her service at NASA.

When describing her youthful obsession, she said, “I counted everything. I counted the steps to the road, the steps up to the church, the number of dishes and silverware I washed… anything that could be counted, I did.” And what did all that counting lead to? The 2015 National Medal of Freedom.

She was an amazing achiever. At the tender age of ten she was a freshman in high school. Imagine that in the time period and circumstances she was in! The gringa is in awe! And, apparently, her father was as well. He did what was necessary to see that his daughter fulfilled her potential.

Eventually he relocated the entire family to Institute, West Virginia so Katherine could complete her education and she graduated college at the age of eighteen.  Katherine then went on to teach, raise a family and eventually work for the National Advisory Committee for Aeronautics in 1953 which would later be replaced by NASA. In the time before there were computers to do the tedious job of counting and recording, people like Katherine did the job.

As a “human computer”, Katherine completed mission assignments like calculating the trajectory for the first American in space, Alan Shepard. Once computers did exist, Katherine was the back up that double checked the computer’s accuracy on calculations. Her work was so respected that before John Glenn made his spaceflight aboard Friendship 7, he specifically asked for Katherine to do the recheck on his mission calculations.

Katherine worked on the Apollo Moon landing mission as well as the early beginnings of the shuttle program. She continued to serve the people of the United States of America, as well as the entire world, through her extraordinary work at NASA until 1986.

The Presidential Medal of Freedom medal that she was awarded on Tuesday, November 24, 2015, was not the only merit to her name. In addition to honorary doctorates, in 1967 she received the NASA Lunar Orbiter Spacecraft and Operations team award for her work in navigation.

What does NASA have to say about Katherine? The following are quoted from NASA Administrator Charles Bolden’s public statement:

“She’s one of the greatest minds ever to grace our agency or our country…”

“Katherine’s legacy is a big part of the reason that my fellow astronauts and I were able to get to space…”

NASA Deputy Administrator Dava Newman said:  “We are fortunate that when faced with the adversity of racial and gender barriers, she found the courage to say ‘tell them I’m coming’.

And the gringa will close with those simple yet bold words from a great woman.
