Space Exploration Technologies Corp., doing business as SpaceX, is a private American aerospace manufacturer and space transportation services company headquartered in Hawthorne, California. SpaceX has flown twenty-five (25) resupply missions to the International Space Station (ISS) under a partnership with NASA. As you all know, NASA no longer undertakes missions of this sort but relies upon private companies such as Space X for delivery of supplies and equipment to the ISS as well as launching satellite “dishes” for communications.

BACKGROUND: 

Entrepreneur Elon Musk, founded PayPal and Tesla Motors is the visionary who started the company Space Exploration Technologies.   In early 2002 Musk was seeking staff for the new company and approached rocket engineer Tom Mueller, now SpaceX’s CTO of Propulsion.  SpaceX was first headquartered in a seventy-five thousand (75,000) square foot warehouse in El Segundo, California. Musk decided SpaceX’s first rocket would be named Falcon 1, a nod to Star Wars’ Millennium Falcon. Musk planned Falcon 1’s first launch to occurring in November 2003, fifteen (15) months after the company started. When you think about the timing, you must admit this is phenomenal and extraordinary.   Now, the fact that is was an unmanned mission certainly cut the time due to no need for safety measures to protect the crew.  No redundant systems needed other than protecting the launch and cargo itself.

In January 2005 SpaceX bought a ten percent (10%) stake in Surrey Satellite Technology and by March 2006, Musk had invested US $100 million in the company.

On August 4, 2008 SpaceX accepted a further twenty ($20) million investment from Founders Fund.   In early 2012, approximately two-thirds of the company was owned by its founder Must with seventy  (70) million shares of stock estimated to be worth $875 million on private markets.  The value of SpaceX was estimated to be at $1.3 billion as of February 2012.   After the COTS 2+ flight in May 2012, the company private equity valuation nearly doubled to $2.4 billion.

SATELLITE LAUNCH:

The latest version of SpaceX’s workhorse Falcon 9 rocket lifted off for the second time on July 22, lighting up the skies over Florida’s Space Coast in a dazzling predawn launch.  The “Block 5” variant of the two-stage Falcon 9 blasted off from Cape Canaveral Air Force Station at 1:50 a.m. EDT (0550 GMT), successfully delivering to orbit a satellite for the Canadian communications company Telesat.     Less than nine (9) minutes after launch, the rocket’s first stage came back down to Earth, a with a successful landing aboard the SpaceX drone ship “Of Course I Still Love You” a few hundred miles off the Florida coast.  The Falcon 9 may be seen with the JPEG below.

The Block 5 is the newest, most powerful and most reusable version of the Falcon 9.  Musk said the Block 5 first stages are designed to fly at least ten (10) times with just inspections between landing and liftoff, and one hundred (100) times or more with some refurbishment involved.

Such extensive reuse is key to Musk’s quest to slash the cost of spaceflight, making Mars colonization and other bold exploration efforts economically feasible. To date, SpaceX has successfully landed more than two dozen Falcon 9 first stages and re-flown landed boosters on more than a dozen occasions.

The only previous Block 5 flight occurred this past May 2018 and also involved a new rocket configuration.  The satellite lofted is called Telstar 19V, is headed for geostationary orbit, about 22,250 miles (35,800 kilometers) above Earth. Telstar 19V, which was built by California-based company SSL, will provide broadband service to customers throughout the Americas and Atlantic Ocean region, according to a Telesat fact sheet.

The booster’s first stage, sporting redesigned landing legs, improved heat shield insulation, upgraded avionics and more powerful engines with crack-resistant turbine hardware, flipped around moments after falling away from the Falcon 9’s second stage and flew itself back to an on-target landing on an offshore drone-ship.

It was the 25th successful booster recovery overall for SpaceX and the fifth so far this year, the latest demonstration of SpaceX’s maturing ability to bring orbit-class rockets back to Earth to fly again in the company’s drive to dramatically lower launch costs.

CONCLUSION:

I think the fact that Musk has taken on this project is quite extortionary.  Rocket launches, in times past, have represented an amazing expenditure of capital with the first and second stages being lost forever.  The payload, generally the third stage, go on to accomplish the ultimate mission.  Stages one and two become space debris orbiting Earth and posing a great menace to other launches.  Being able to reuse any portion of stages one and two is a great cost-effective measure and quite frankly no one really though it could be accomplished.

SOCIAL MEDIA

June 27, 2018


DEFINITION:

Social media is typically defined today as: – “Web sites and applications that enable users to create and share content or to participate in social networking” – OxfordDictionaries.

Now that we have cleared that up, let’s take a look at the very beginning of social media.

Six Degrees, according to several sources, was the first modern-day attempt of providing access to communication relative to the “marvelous world” of social media. (I have chosen to put marvelous world in quotes because I’m not too sure it’s that marvelous. There is an obvious downside.)  Six Degrees was launched in 1997 and definitely was the first modern social network. It allowed users to create a profile and to become friends with other users. While the site is no longer functional, at one time it was actually quite popular and had approximately a million members at its peak.

Other sources indicate that social media has been around for the better part of forty (40) years with Usenet appearing in 1979.  Usenet is the first recorded network that enabled users to post news to newsgroups.  Although these Usenets and similar bulletin boards heralded the launch of the first, albeit very rudimentary, social networks, social media never really took off until almost thirty (30) years later, following the roll out of Facebook in 2006. Usenet was not identified as “social media” so the exact term was not used at that time.

If we take a very quick look at Internet and Social Media usage, we find the following:

As you can see from above, social media is incredibly popular and in use hourly if not minute-by-minute.  It’s big in our society today across the world and where allowed.

If we look at the fifteen most popular sites we see the following:

With out a doubt, the gorilla in the room is Facebook.

Facebook statistics

  • Facebook adds 500,000 new users a day – that’s six new profiles a second – and just under a quarter (775) of adults in the US visit their account at least once a month
  • The average (mean) number of Facebook friends is 155
  • There are 60 million active small business pages (up from 40 million in 2015), 5 million of which pay for advertising
  • There are thought to be 270 million fake Facebook profiles (there were only81 million in 2015)
  • Facebook accounts for 1% of social logins made by consumers to sign into the apps and websites of publishers and brands.

It’s important we look at all social media sites so If we look at daily usage for the most popular web sites, we see the following:

BENEFITS:

  • Ability to connect to other people all over the world. One of the most obvious pros of using social networks is the ability to instantly reach people from anywhere. Use Facebook to stay in touch with your old high school friends who’ve relocated all over the country, get on Google Hangouts with relatives who live halfway around the world, or meet brand new people on Twitter from cities or regions you’ve never even heard of before.
  • Easy and instant communication. Now that we’re connected wherever we go, we don’t have to rely on our landlines, answering machines or snail mail to contact somebody. We can simply open up our laptops or pick up our smartphones and immediately start communicating with anyone on platforms like Twitter or one of the many social messaging apps
  • Real-time news and information discovery. Gone are the days of waiting around for the six o’clock news to come on TV or for the delivery boy to bring the newspaper in the morning. If you want to know what’s going on in the world, all you need to do is jump on social media. An added bonus is that you can customize your news and information discovery experiences by choosing to follow exactly what you want.
  • Great opportunities for business owners. Business owners and other types of professional organizations can connect with current customers, sell their products and expand their reach using social media. There are actually lots of entrepreneurs and businesses out there that thrive almost entirely on social networks and wouldn’t even be able to operate without it.
  • General fun and enjoyment. You have to admit that social networking is just plain fun sometimes. A lot of people turn to it when they catch a break at work or just want to relax at home. Since people are naturally social creatures, it’s often quite satisfying to see comments and likes show up on our own posts, and it’s convenient to be able to see exactly what our friends are up to without having to ask them directly.

DISADVANTAGES:

  • Information overwhelm. With so many people now on social media tweeting links and posting selfies and sharing YouTube videos, it sure can get pretty noisy. Becoming overwhelmed by too many Facebook friends to keep up with or too many Instagram photos to browse through isn’t all that uncommon. Over time, we tend to rack up a lot of friends and followers, and that can lead to lots of bloated news feeds with too much content we’re not all that interested in.
  • Privacy issues. With so much sharing going on, issues over privacy will always be a big concern. Whether it’s a question of social sites owning your content after it’s posted, becoming a target after sharing your geographical location online, or even getting in trouble at work after tweeting something inappropriate – sharing too much with the public can open up all sorts of problems that sometimes can’t ever be undone.
  • Social peer pressure and cyber bullying. For people struggling to fit in with their peers – especially teens and young adults – the pressure to do certain things or act a certain way can be even worse on social media than it is at school or any other offline setting. In some extreme cases, the overwhelming pressure to fit in with everyone posting on social media or becoming the target of a cyber-bullying attack can lead to serious stress, anxiety and even depression.
  • Online interaction substitution for offline interaction. Since people are now connected all the time and you can pull up a friend’s social profile with a click of your mouse or a tap of your smartphone, it’s a lot easier to use online interaction as a substitute for face-to-face interaction. Some people argue that social media actually promotes antisocial human behavior.
  • Distraction and procrastination. How often do you see someone look at their phone? People get distracted by all the social apps and news and messages they receive, leading to all sorts of problems like distracted driving or the lack of gaining someone’s full attention during a conversation. Browsing social media can also feed procrastination habits and become something people turn to in order to avoid certain tasks or responsibilities.
  • Sedentary lifestyle habits and sleep disruption. Lastly, since social networking is all done on some sort of computer or mobile device, it can sometimes promote too much sitting down in one spot for too long. Likewise, staring into the artificial light from a computer or phone screen at night can negatively affect your ability to get a proper night’s sleep. (Here’s how you can reduce that blue light, by the way.)

Social media is NOT going away any time soon.  Those who choose to use it will continue using it although there are definite privacy issues. The top five (5) issues discussed by users are as follows:

  • Account hacking and impersonation.
  • Stalking and harassment
  • Being compelled to turn over passwords
  • The very fine line between effective marketing and privacy intrusion
  • The privacy downside with location-based services

I think these issues are very important and certainly must be considered with using ANY social media platform.  Remember—someone is ALWAYS watching.

 

CAN YOU RETIRE

May 29, 2018


At some time in our working future we all hope to retire, but one burning question lingers—can you retire on what you have or will save at that point?  We are told that:

At some point in your life, you’ll be using this money to support your lifestyle. By the time you reach sixty (60), you should have six times your salary saved – that’s $360,000 if you make $60,000 per year. Unfortunately, the average sixty-something has an estimated median of $172,000 in the bank.  That is an estimate as of December 8, 2016.  Nearly half of American families have no retirement account savings at all.  This really blows my mind but this fact is what we are told by the Economic Policy Institute (EPI) in a new report entitled, “The State of American Retirement”.  Please take a look at the graphic below and you can see age groups vs retirement account savings.

Whereas the average savings of a family with members in the 32-to-37 age range is $31,644, the median savings is a bleak $480. At the other end, the average savings of families 56 to 61 — those nearest to retirement — is $163,557. The median is $17,000.

I think there are very specific reasons for the lack of savings, especially for younger citizens of our country.  Student loans, cost of living, pay scales, credit card debt, living above ones means, etc. all contribute to the inability to save or at least save enough for retirement.

The web site called MoneyWise.com has a very interesting solution to this problem or possible solution.  If you go to this web site and look up the following post: “Places You can Retire to for Less Than $200K” you will see a list of twenty (20) countries that can supply most if not all of your needs if your retirement is less than $200 K.  Let’s take a look at the list in order of favorability.

Thailand

Costa Rica

Nicaragua

Malaysia

Mexico

Malta

Ecuador

Spain

Portugal

Panama

Australia

Austria

Czech Republic

Slovenia

Chile

Uruguay

Vietnam

Guam

Indonesia

South Africa

MoneyWise.com completed a study comparing housing availability, cost of living, health care, crime, government and several other indicators to compile this list.  It is a very interesting study and I encourage you to take a look even if you are not considering being an expatriate. You just might change your mind.

There are two other web sites I definitely recommend you check out as follows: 1.)  The CIA Fact Book and 2.) Lonely Planet.  From these two you will find very valuable information relative to any country you wish to research.  Look before you leap might just be in order here. Another option might be spending time and not completely relocating.  Two, three, six or even nine months during one year might get you beyond worry relative to being able to afford retirement on what you have saved.  The most important thing is to DO THE RESEARCH.  Make a list, then a short list of the countries that represent the leading candidates. THEN MAKE A VISIT. Wade—don’t jump.  Several other considerations I would list are as follows:

  • Make sure you consider your family, friends and support group before you make the move. Will they be willing and able to visit on a regular basis if needed?
  • A huge factor for me would be availability of good if not excellent medical facilities.
  • Cost of transportation.
  • Language considerations. If English is an issue, how difficult would learning their language be?
  • Power supplied. (I know this is off the wall.) Does the country provide 120-volt AC, 60 cycles per second or do they provide another voltage and frequency?  In other words, will your electronics work?  Will you have to buy new equipment or can a converter do the job?
  • How difficult and costly is communication “back home”? This includes Internet services.
  • Viability of local banking institutions
  • Stability of government
  • Weather factors

This is where good research is a MUST.

THE RIGHT SNUFF

May 7, 2018


This past weekend my wife traveled to ‘Hot-Lanta (Atlanta) to attend a baby shower.  Other family members went also but I decided, for several reasons, not to attend.  After a long day of working around the house, (I really did.) I decided to get dinner at a local Italian restaurant called Provino’s.  Absolutely great Italian food.   While seated, I noticed a young couple entering and sitting in an adjoining booth at my two o’clock position.  No doubt about this one, they were on a date and apparently their first date.  He was really nervous and immediately knocked over a full glass of water.  The young lady called a waiter and she quickly removed all of the silverware, glasses, plates, etc. and moped up.  After the commotion, things settled down a bit but he then realized he had a chew of tobacco he had to “lose” before going much further.  Well he did the right thing, he excused himself and I assume took the short trip to the men’s room to dislodge the plug.  Not a great start but at least she did not walk out on him and call UBER.  I started thinking about smokeless tobacco and the health effects related to usage and decided to take a look at what we know.

I was actually startled to learn the following facts from the CDC relative to usage:

  • Adults aged eighteen (18) years and older: more than three (3) in every 100 (3.4%)
  • Men: nearly seven (7) in every 100 (6.7%)
  • Women: fewer than one (1) in every 100 (0.3%)
  • Non-Hispanic African Americans: more than one (1) in every 100 (1.2%)
  • Non-Hispanic American Indians/Alaska Natives: more than seven (7) in every 100 (7.1%)
  • Non-Hispanic Asians: fewer than one (1) in every 100 (0.6%)
  • Hispanics: fewer than one (1) in every 100 (0.9%)
  • Non-Hispanic Whites: nearly five (5) in every 100 (4.6%)

The following chart will show the usage.

Smokeless tobacco is definitely a health hazard—a considerable health hazard: *Leukoplakia, oral lesions that appear as white patches on the cheeks, gums or tongue, are commonly found present in smokeless tobacco users. Leukoplakia can be a pre-cancerous lesion which may ultimately produce oral cancer. About seventy-five (75%) percent of daily users of smokeless tobacco will get leukoplakia. (American Cancer Society) Dec 14, 2016.   Researchers estimated that in 2010 alone, smokeless tobacco caused more than 62,000 deaths due to cancers of the mouth, pharynx and esophagus, and more than 200,000 deaths from heart disease. Sep 2, 2015.   You may think that dipping is less hazardous than chewing tobacco but it definitely is NOT.  Overall, people who dip or chew get about the same amount of nicotine as regular smokers. They also get at least thirty (30) chemicals that are known to cause cancer. The most harmful cancer-causing substances in smokeless tobacco are tobacco-specific nitrosamines (TSNAs). Nov 13, 2015.    With this being the case, just how long does it take some users to develop health issues when using smokeless tobacco?  Some athletes have developed mouth cancer after only six (6) or seven (7) years of using spit tobacco. It’s hard to cure because it spreads fast. If not caught right away, major surgery is often needed to take out parts of your mouth, jaw, and tongue.

WARNING:

I’m going to show you several pictures that indicate the results of using smokeless tobacco (dipping and chewing).  These are not for the squeamish so if you need to leave this blog, now is the time to do it.

READY TO QUIT NOW?

DOMESTIC TRANQUILITY

April 28, 2018


I am gong to deviate from my usual STEM post and do a little politics, the subject being “Domestic Tranquility”.  The need to achieve domestic tranquility goes back a long time.  Remember this?

“We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of the Unites States of America.”

These words are the preamble to our Constitution.  Basically, if I read this correctly, a more perfect union just might depend upon justice, insuring domestic tranquility, providing for the common defense and promoting the general welfare.   Most people will agree, we really are not there with no real signs of getting there too quickly relative to tranquility, domestic or otherwise.   Domestic tranquility generally means peace at home. It is meant with reference to family as well as states. Domestic Tranquility with regard to constitution is referred to peace among the states. Constitution gives power to federal government squash rebellion and to smooth tensions between states

Recent polls have confirmed that Americans are feeling bitterly split. A Gallup poll conducted just after the 2016 presidential election found seventy-seven (77) percent of Americans see the country as “greatly divided when it comes to the most important values,” up from sixty-six (66) percent in 2012. A Washington Post-University of Maryland poll, conducted nine months into Trump’s presidency, found that seven in ten (10) Americans think the nation’s political divisions are as bad as during the Vietnam War.  Kwame Anthony Appiah, a professor of philosophy at Princeton University, said this kind of division has been rare in the U.S. While the country has faced many periods of intense disagreement and strife, he said, what’s unusual is the current tendency of some Americans to argue that others don’t belong in the country at all. This approach to politics has appeared only occasionally in U.S. history. For example, in the Jacksonian period, Andrew Jackson’s supporters sharply defined Americans as English-speaking Christians of European origin, while in the McCarthy years, people with particular political views or lifestyles could be declared un-American and denied basic constitutional protections.

One element in today’s world that divides us even more is social media.

SOCIAL MEDIA:

Social media may be society’s gateway to a global connection that we have never seen before, but if we look closely, social media has played a significant role in dividing us more than it connects us.  Take any issue or topic developing domestically or internationally. Whatever this issue is, social media platforms, such as Facebook Instagram, Snapchat, Twitter, etc. play a prominent role in adding fuel to the fire. With the ability to express ourselves without face to face interaction, this opens the door for a much different form of debating. We are all a part of the term “keyboard warrior.” At one point, we have all fallen into this category. It feels as if this is the direction our country is moving in. Nothing is being resolved because we don’t look for resolutions anymore. We just look for the next opportunity to slander the opposite belief. I feel as if this won’t change but it will just get more and more relevant as we extend further and further into our newly found self-extension that has become our social media profiles.  This is demonstrated each night with late-night comics working towards greater ratings.  They use as their platform the political issues of the day.

Our social skills are falling while our social media skills are rising. This idea that our Facebook rants will change the world is far from true. The truth is if you want change, get off your high horse and go out and do something about it. Your Facebook essay on why something is wrong isn’t going to do anything but make you look like a fool. Stop sitting around and waiting for the change you seek and go out and become the change you so desperately want to see invoked in our world. We must take a hold of this issue before it consumes our youngest generation. These kids will one day be our executives. If they grow up in a solely social media-dominated world, it will have devastating effects on generations to come.

Let’s take a look at what course of action might help achieve domestic tranquility.

  • ELIMINATE POLITICAL PARTIES: When George Washington became President of the United States in 1789, there were no political parties. Political parties first emerged during Washington’s first term in office with the Alexander Hamilton’s Federalist Party in 1791 and in the following year, the formation of the Anti-Federalist Party or Democratic-Republicans under the leadership of Thomas Jefferson. The two political parties formulated their views of how government ought to operate in the new republic. At the end of Washington’s first term, as he was preparing to retire and go back to Mt. Vernon to just be a farmer again, the leaders of the opposing parties both wanted him to reconsider with Hamilton and Jefferson pleading with Washington to stay on for a second term. Washington was against political parties and felt they would detract from governing.
  • EXTEND THE HOUSE OF REPRESENTATIVES TERM TO FOUR (4) YEARS. John Larson (D-Conn.) is pushing to extend the terms of House members to four years to free them from the pressures of constant fundraising. In an interview with The Hill, Larson said extending the terms and staggering them so that half of the House is up for reelection every two years would let members prioritize learning the ropes in Congress over campaign cash. “I think the two-year cycle and all the demands that places on individuals tends to lend itself to one chasing their tail in terms of raising the money required to get reelected,” Larson said. Larson said new members arrive in Washington for freshman orientation only to be told to start dialing for dollars again.
    “The first orders that the Republican Conference and Democratic Caucus give is, ‘Get on the phone and start raising money again. You’ve got an election coming up.’ And I think that we ought to reverse that priority,” Larson said.
  • MAKE THE LEGISLATIVE BRANCH OF OUR GOVERNMENT ABIDE BY THE RULES THEY PASS: Republican Senator from Kentucky, Rand Paul, introduced a Constitutional Amendment in the recent past that would prohibit members of Congress from passing laws “applicable to a citizen of the United States that is not equally applicable to Congress.”

Section 1. Congress shall make no law applicable to a citizen of the United States that is not equally applicable to Congress.

Section 2. Congress shall make no law applicable to a citizen of the United States that is not equally applicable to the executive branch of Government, including the President, Vice President, ambassadors, other public ministers and consuls, and all other officers of the United States, including those provided for under this Constitution and by law, and inferior officers to the President established by law.

Section 3. Congress shall make no law applicable to a citizen of the United States that is not equally applicable to judges of the Supreme Court of the United States, including the Chief Justice, and judges of such inferior courts as Congress may from time to time ordain and establish.

Section 4. Nothing in this article shall preempt any specific provision of this Constitution.’

I hate to say it, but the law doesn’t have a chance at passing. If it did, Congress would understand the destress many Americans feel toward laws that restrict activity and commerce.

  • REGULATE SOCIAL MEDIA: Basically, no hate speech.  (This would never pass due to too much backlash from the “talking heads” on television and the politicians themselves.)

I certainly welcome your comments and I’m sure there are many many more action items that could contribute to tranquility.


I feel that most individuals, certainly most adults, wonder if anyone is out there.  Are there other planets with intelligent life and is that life humanoid or at least somewhat intelligent?  The first effort would be to define intelligent.  Don’t laugh but this does have some merit and has been considered by behavioral scientists for a significant length of time.  On Earth, human intelligence took nearly four (4) Billion years to develop. If living beings develop advanced technology, they can make their existence known to the Universe. A working definition of “intelligent” includes self-awareness, use of tools, and use of language. There are other defining traits, as follows:

  • Crude perceptive abilities: Like concept of a handshake (sending a message and acknowledging receipt of one sent by you)
  • Crude communication abilities: Some primitive language and vocabulary
  • Sentience: Should be able of original thought and motivation, some form of self -awareness
  • Retention: Ability to remember and recall information on will
  • Some form of mathematical ability like counting

Please feel free to apply your own definition to intelligence. You will probably come as close as anyone to a workable one.

TESS:

NASA is looking and one manner in which the search occurs is with the new satellite TESS.

The Transiting Exoplanet Survey Satellite (TESS) is an Explorer-class planet finder.   TESS will pick up the search for exoplanets as the Kepler Space Telescope runs out of fuel.

Kepler, which has discovered more than 4,500 potential planets and confirmed exoplanets, launched in 2009. After mechanical failure in 2013, it entered a new phase of campaigns to survey other areas of the sky for exoplanets, called the K2 mission. This enabled researchers to discover even more exoplanets, understand the evolution of stars and gain insight about supernovae and black holes.

Soon, Kepler’s mission will end, and it will be abandoned in space, orbiting the sun, therefore:  never getting closer to Earth than the moon.

The spaceborne all-sky transit survey, TESS will identify planets ranging from Earth-sized to gas giants, orbiting a wide range of stellar types and orbital distances. The principal goal of the TESS mission is to detect small planets with bright host stars in the solar neighborhood, so that detailed characterizations of the planets and their atmospheres can be performed. TESS is only one satellite used to determine if there are any “goldy-locks” planets in our solar system. TESS will survey an area four hundred (400) times larger than Kepler observed. This includes two hundred thousand (200,000) of the brightest nearby stars. Over the course of two years, the four wide-field cameras on board will stare at different sectors of the sky for days at a time.

TESS will begin by looking at the Southern Hemisphere sky for the first year and move to the Northern Hemisphere in the second year. It can accomplish this lofty goal by dividing the sky into thirteen (13) sections and looking at each one for twenty-seven (27) days before moving on to the next.

The various missions launched to discover exoplanets may be seen below.

As mentioned earlier, TESS will monitor the brightness of more than two hundred thousand (200,000) stars during a two-year mission, searching for temporary drops in brightness caused by planetary transits. Transits occur when a planet’s orbit carries it directly in front of its parent star as viewed from Earth. TESS is expected to catalog more than fifteen hundred (1,500) transiting exoplanet candidates, including a sample of approximately five hundred (500) Earth-sized and ‘Super Earth’ planets, with radii less than twice that of the Earth. TESS will detect small rock-and-ice planets orbiting a diverse range of stellar types and covering a wide span of orbital periods, including rocky worlds in the habitable zones of their host stars.  This is a major undertaking and you might suspect so joint-ventures are an absolute must.  With that being the case, the major parterners in this endeavor may be seen as follows:

The project overview is given by the next pictorial.

In summary:

TESS will tile the sky with 26 observation sectors:

  • At least 27 days staring at each 24° × 96° sector
  • Brightest 200,000 stars at 1-minute cadence
  • Full frame images with 30-minute cadence
  • Map Southern hemisphere in first year
  • Map Northern hemisphere in second year
  • Sectors overlap at ecliptic poles for sensitivity to smaller and longer period planets in JWST Continuous Viewing Zone (CVZ)

TESS observes from unique High Earth Orbit (HEO):

  • Unobstructed view for continuous light curves
  • Two 13.7-day orbits per observation sector
  • Stable 2:1 resonance with Moon’s orbit
  • Thermally stable and low-radiation

The physical hardware looks as follows:

You can’t tell much about the individual components from the digital picture above but suffice it to say that TESS is a significant improvement relative to Kepler as far as technology.  The search continues and I do not know what will happen if we ever discover ET.  Imagine the areas of life that would affect?

 

 

THE MOSES ILLUSION

April 8, 2018


Portions of this post were taken from an article in The Chattanooga Times-FreePress.

Let’s do a quick quiz:

QUESTION:  In the Biblical story, what was Jonah swallowed by?  How many animals of each kind did Moses take on the ark?

Did you answer whale to the first question and two of each kind to the second question?  Most people actually do, even though they are aware that Noah, and not Moses, built the ark in that story.  Noah—not Moses.  You knew that.

Psychologists call this phenomenon the “Moses Illusion”.  This is just one example of how people are very bad at discerning factual errors in the world around them.  Even when people know the correct information, they often fail to notice errors and will even go on to use that incorrect information in other situations.  An “official” definition of this illusion goes something like this:

“In pragmatics and psycholinguistics, the Moses illusion is a phenomenon whereby listeners or readers fail to recognize an inaccuracy or inconsistency in a text. It is also called the semantic illusion.”

Research from cognitative psychology shows that people are naturally very poor fact-checkers and it is very difficult for individuals to compare things we read or hear with what we already know about a specific topic.   The Moses illusion (also known as semantic illusion) was first identified by T.D. Erickson and M.E. Mattson in their article “From Words to Meaning: A Semantic Illusion” (Journal of Verbal Learning and Verbal Behavior, 1981).

In this era of “fake news”, this reality has very important implications for how people consume journalism, social media and other bits of public information.  In the study mentioned above, eighty (80) percent of the participants failed to notice the error in the question despite later correctly answering the question, “Who took the animals into the Ark? The failure occurred even though participants were warned that some of the questions would have something wrong with them and were given an example of an incorrect question.  Psychologists call this “knowing neglect”.  People have relevant knowledge but fail to use it.

OKAY, why are human beings so bad at noticing errors and misinformation? Psychologists believe that there are at least two forces at work.

  • First, people have a general bias to believe that things are true. (After all, most things that we read or hear are true.) In fact, there’s some evidence that we initially process all statements as true and that it then takes cognitive effort to mentally mark them as false.  At one time, I personally believed just about everything written.  I suppose it was because I considered this to be somewhat of a legacy relative to the writer.  In days gone by, a non-fiction writer would write to inform and not to confuse.  Back then I felt that most writers did NOT have a political agenda. Today, I would be absolutely incorrect with that supposition.
  • Second, people tend to accept information as long as it’s close enough to the correct information. Natural speech often includes errors, pauses and repeats. (“She was wearing a blue – um, I mean, a black, a black dress.”). One idea– to maintain conversations we need to go with the flow and accept information that is “good enough”. Just move on and if people

don’t fall for these illusions when the incorrect information is obviously wrong. For example, people don’t try to answer the question “How many animals of each kind did Nixon take on the Ark?”.

Detecting and correcting false information is difficult work and requires fighting against the ways our brains like to process information. Critical thinking alone won’t save us. Our psychological quirks put us at risk of falling for misinformation, disinformation and propaganda. Professional fact-checkers provide an essential service in detecting incorrect information in the public view.  They are one of our best hopes for zeroing in on errors and correcting them, before the rest of us read or hear the false information and incorporate it into what we know of the world.

FAKE NEWS:

Why on earth is there so much fake news?

There are two main creators of fake news. The most egregious creator comes from non-journalists who put out spammy garbage you see on the web that’s simply untrue. As mentioned earlier, we generally believe just about everything written with the goal of checking it later, then there is no later.  The second creator of fake news is not so much fake news, but biased news coming from journalists with an agenda. Biased news isn’t as egregious since we all have our biases that are hard to extricate from our actions. However, biased journalists can do greater damage due to their large platforms. I would like to see a disclaimer at the beginning of each blog or tweet, when needed— “WARNING:  this is garbage.”  Don’t hold your breath for this to happen.

With the use of clickbait titles, misinformation, and satire, fake news has the ability to affect public opinion about a person, country or issue. I am amazed at the number of people who gain information, political and otherwise from the late-night television shows.

Findings indicate viewers of late night talk shows tend to be politically unsophisticated and low news media consumers, relying on incidental exposure to news about current events that are introduced throughout the day in the course of other activities (i.e., news headlines on email servers, jokes in late night monologues) with one notable exception.  Viewers of “The Daily Show,” are on the other end of the political spectrum, reflecting high levels of political sophistication and high news media consumption. They tune into “The Daily Show” for a “twist” on news stories with which they are already familiar, expecting Stewart and his team to provide a humorous slant on current events. Apparently, the other late-night shows—-not so much.  It’s mostly relative to political discourse garbage.

CONCLUSION:

I know I need to slow down and take the time to ask the question—is this information true, partially true, completely false?  What do I know relative to this new information?  I am to the point of turning off the television set and reading a good book.  Who do you believe these days?  What news or media outlet gives a non-bias, only-the-facts, information-filled narrative?  I honestly can NOT answer that question at this time.
