” Astronaut Chris Hadfield Explains The Big Problem With The Mars One Mission”

If you haven’t heard, there’s a plan to start up a colony of humans living on Mars in the near future.

If the next decade goes as planned, the not-for-profit organization, Mars One, will launch a manned mission to Mars that will land the first human colony on the red planet in 2025.

Here’s the catch: Those who leave Earth for the 7-month-long ride in space will never return.

The four-member crew will learn to call Mars – a freezing, barren, lifeless planet – home. Forever.

That may sound great to the tens of thousands of people who applied, but Mars One is going about their grandiose plans all wrong according to retired Canadian Space Agency astronaut Chris Hadfield.

Right now, Mars One is focused more on raising funds and selecting crew members than developing the technology needed for the trip. And the technology, Hadfield told Elmo Keep, writing in Medium, is the most basic starting point for any space mission.

“There’s a great, I don’t know, self-defeating optimism in the way that this project has been set up,” Hadfield told Keep. “I fear that it’s going to be a little disillusioning for people, because it’s presented as if for sure it’s going to happen.”

So far, the company claims they’ve had more than 200,000 people apply, and are about to start interviews with 663 final candidates. Mars One says that they will gather the majority of money for the trip through crowd funding from a global reality television event.

The company anticipates that the trip to Mars will cost approximately $6 billion (that’s shockingly low compared to NASA estimates for a two-way trip to Mars and back costing roughly $100 billion.)

Although Mars One has visions of partnering with companies like SpaceX to procure the proper technology, so far its only contract is with Paragon Space Development Corporation to study initial life support systems.

Hadfield isn’t the only one doubting this project. Doubters at MIT have calculated that “living on Mars” will last only about 68 days before the colonists die.

In particular, Hadfield said, if you don’t have the specifications of the spacecraft, you can’t begin to select the people who will live and work in it.

“I want to see the technical specifications of the vehicle that is orbiting Earth,” Hadfield said. “I want to know: How does a space suit on Mars work? Show me how it is pressurized, and how it is cooled. What’s the glove design?”

What’s more, Mars should not even be a target for colonization at this point, according to Hadfield. Our sites should be set on a place much closer.

“We absolutely need to do it on the moon for a few generations,” Hadfield told Keep.

On average, the moon is about 600 times closer to Earth than Mars. That means if something goes wrong with a colony, we can dispatch help from Earth that will reach the Moon in a matter of hours instead of months. Developing a working moon colony would be an important first step to living on Mars.

Astronaut Eugene A. Cernan of Apollo 17 tests the Lunar Roving Vehicle on the moon.

Here’s a short list of what Hadfield told Keep we need to know before living on Mars:

  • How do you completely recycle your water?
  • How do you completely recycle your oxygen system?
  • How do you protect yourselves from radiation?
  • How do you not go crazy?
  • How do you set up the politics of the place and the command structure, so that when we get it wrong we won’t all die?

While the Mars One desire to get people excited about space travel again is noble – it has been more than 42 years since we last landed a human on anything in space besides the International Space Station. There’s a right way and a wrong way to go about landing people on other satellites throughout the solar system.

“It’s not a race, it’s not an entertainment event. We didn’t explore the world to entertain other people. We did it as a natural extension of human curiosity and matching capability,” Hadfield told Keep. “And that’s what will continue to drive us.”

Joke of the Day…” Think Hard and Tell the Answer …” !!!

                 A Detective Story !!!

A policeman was interrogating 3 blondes who were training to become detectives. To test their skills in recognizing a suspect, he shows the first blonde a picture for 5 second and then hides it.

“This is your suspect, how would you recognize him?”
 
The first blonde answers, “That is easy, we’ll catch him fast because he only has one eye!”

blond pointing

 
The policeman says, “Well…uh…that is because the picture shows his PROFILE.”
 
Slightly flustered by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, “This is your suspect, how would you recognize him?”
 
The second blonde giggles, flips her hair and says, “Ha! He’d be too easy to catch because he only has one ear!”
 
The policeman angrily responds, “What’s the matter with you two?? Of course only one eye and one ear are SHOWING because it’s a picture of his profile!! Is that the best answer you can come up with?”
 
Extremely frustrated at this point, he shows the picture to the third blonde and in a very testy voice asks, “This is your suspect, how would you recognize him?”
 
He quickly adds “…think hard before giving me a stupid answer.”
 
The blonde looks at the picture intently for a moment and says, “Hmmmm…the suspect wears contact lenses.”
 
The policeman is surprised and speechless because he really doesn’t know himself if the suspect wears contacts or not. “Well, that’s an interesting answer…wait here for a few minutes while I check his file and I’ll get back to you on that.”
 
He leaves the room and goes to his office, checks the suspect’s file in his computer, and comes back with a beaming smile on his face. “Wow! I can’t believe it…it is TRUE! The suspect does in fact wear contact lenses. Good work! How were you able to make such an astute observation?”
 
That is easy,” the blonde replied. “He can’t wear regular glasses because he only has one eye and one ear!”

Will Rogers, who died in a 1935 plane crash, was one of the greatest political sages America has ever known.


Some of his sayings:

* Never slap a man who is chewing tobacco.

* There are two theories to arguing with a woman. Neither works.

* Never miss a good chance to shut up.

* If you find yourself in a hole, stop digging.

* The quickest way to double your money is to fold it and put it back into your
pocket.

* There are three kinds of men:
The ones that learn by reading. The few who learn by observation. The rest of
them have to pee on the electric fence and find out for themselves.

* Good judgment comes from experience, and a lot of that comes from bad judgment.

* If you’re riding ahead of the herd, take a look back every now and then to make
sure it is still there.

* Letting the cat outta the bag is a whole lot easier than putting it back.

* After eating an entire bull, a mountain lion felt so good he started roaring.He
kept it up until a hunter came along and shot him.
The moral: When you’re full of bull, keep your mouth shut.

ABOUT GROWING OLDER..
First ~Eventually you will reach a point when you stop lying about your age and
start bragging about it.

Second ~ The older we get, the fewer things seem worth waiting in line for.

Third ~ Some people try to turn back their odometers. Not me. I want people to
know ‘why’I look this way. I’ve traveled a long way, and some of the roads
weren’t paved.

Fourth ~ When you are dissatisfied and would like to go back to youth, think of
Algebra.

Fifth ~ You know you are getting old when everything either dries up or leaks.

Sixth ~ I don’t know how I got over the hill without getting to the top.

Seventh ~ One of the many things no one tells you about aging is that it’s such a nice change from being young.

Eighth ~ One must wait until evening to see how splendid the day has been.

Ninth ~ Being young is beautiful, but being old is comfortable.

Tenth ~ Long ago, when men cursed and beat the ground with sticks, it was called witchcraft. Today it’s called golf.

And, finally ~ If you don’t learn to laugh at trouble, you won’t have anything to
laugh at when you’re old.

THE CONCRETE JUNGLE

The Judge Harry Pregerson Interchange is a stack interchange near the Athens and Watts communities of Los Angeles, California. Though the interchange permits traffic entering the interchange in all directions to exit in all directions (cf. Hollywood Split, East Los Angeles Interchange), the interchange also consists of direct HOV (high-occupancy vehicle) connectors, Metro Green Line tracks, and the Harbor Transitway, all of which contribute to the towering, imposing structure for which the interchange is known.

Opened with Interstate 105 in 1993, the interchange is named for Harry Pregerson, a longtime federal judge who presided over the lawsuit concerning the I-105 freeway’s construction. Shortly before the interchange opened, filmmakers had access to use it for the 1994 motion picture Speed. In one of the movie’s best-known scenes, the bus must jump across an unfinished construction gap in an uncompleted elevated freeway-to-freeway ramp while still under construction.

In 1996, the U.S. Federal Highway Administration recognized the Interstate 105/Interstate 110 interchange with an Award of Merit in the Urban Highways category of its biennial Excellence in Highway Design awards. The award recognized the interchange’s design which sought to improve traffic congestion, safety, and air quality. [Source: Wikipedia]

” முருகன் திருவிளையாடல்…அருணகிரிநாதர்-வில்லிப்புத்தூரார் மோதல் ..!!!”

முருகன் புகழைக் கூறும் திருப்புகழ் முதலான நவமணி நூல்களை இய்ற்றியருளியவர் அருட்கவி அருணகிரிநாதர். ஒருமுறை அவர், மஹாபாரதத்திற்குத் தமது அற்புத வாக்கால் உரை எழுதிய வில்லிபுத்தூராரைச் சந்திக்க நேர்ந்தது. பெரும் புலவரான வில்லிபுத்தூராரைக் கண்டு புலவர் சமூகமே நடுங்கிக்கொண்டிருந்த காலகட்டம் அது. காரணம் அவர், தன்னுடன் வாது செய்து தோற்ற புலவர்களின் காதுகளைக் குறடு கொண்டு தோண்டும் வழக்கத்தைக் கையாண்டு வந்தார். அவரது செருக்கை அடக்க திருவுளம் கொண்ட முருகன், ஒரு திருவிளையாடலை நிகழ்த்த முடிவு செய்தான்.அருணகிரியாரை, வில்லிபுத்தூராருடன் கவிதைப் போட்டியில் மோதவைப்பதென்றும், தோற்றவர் காதை, மற்றவர் அறுத்துவிடலாம் எனவும் முடிவாயிற்று.

Arunagirinathar

ருணகிரிநாதர், போட்டிக்காகப் பாடவேண்டி இருந்ததால், கடினமான தமிழ் நடையைக் கொண்ட ‘கந்தர் அந்தாதி’ எனும் நூலை இயற்றத் துவங்கினார்.வில்லிபுத்தூராரும் உடனுக்குடன் உரை கூறலானார் .53 செய்யுட்கள் இவ்வாறு நிறைவுற்றபின் மேலும் எப்படிப் பாடினால் அவரை மடக்கலாம் என்று அருணகிரியார் முருகனை எண்ணித் துதித்து நின்ற போது, ‘த’கர வர்க்க எழுத்துக்களை மட்டுமே வைத்து அடுத்த செய்யுளைப் பாடுமாறு முருகன் எடுத்துக் கொடுத்தான்.அந்தச் செய்யுள் பின்வருமாறு:

திதத்தத்தத் தித்தத் திதிதாதை தாததுத் தித்தத்திதா
திதத்தத்தத் தித்த திதித்தித்த தேதுத்து தித்திதத்தா
திதத்தத்தத் தித்தத்தை தாததி தேதுதை தாததத்து
திதத்தத்தத் தித்தித்தி தீதீ திதிதுதி தீதொத்ததே

உயிர் போகும் காலத்தில், முருகன் அடியிணை பெறும் கருணையைத் தரக்கேட்டு அருணகிரியார் பாடிய மேற்குறிப்பிட்ட 54ஆம் பாடலுக்கு உரை கூற முடியாது தவித்தார் வில்லிபுத்தூரார்! தம் தோல்வியை அவர் ஒப்புக்கொண்டதும், அருணை முநிவர் தாமே அப்பாடலுக்கு உரை செய்தார்.அத்துடன் மொத்தம் நூறு பாடல்களைப் பாடி நூலை நிறைவு செய்தார்.ஆனால் வில்லிபுத்தூராரின் காதை அறுக்க ஒப்புக்கொள்ளவில்லை நம் கருணை முநிவர். ‘.இனியும் இது போன்ற இழிவுச் செயல்களில் ஈடுபடக்கூடாது.’ என்று அறிவுரை கூறியதோடு அவர் கையிலிருந்த குறடாவைப் பிடுங்கி வீசி எறிந்தார் என்பது வரலாறு.

கந்தர் அந்தாதிப் பாடல்கள் அனைத்துமே, சி,சீ,செ,சே,த,தீ,தெ,தே எனும் எட்டு எழுத்துக்களை மட்டுமே கொண்டு துவங்குகின்றன. 27 பாடல்களில் திருச்செந்தூரைப் பற்றிய குறிப்புகள் வருவதால், செந்தூரில் இது பாடப்பட்டிருக்கலாம் என்பதும், திருவண்ணாமலைக் கோவிலிலுள்ள யானை திறை கொண்ட விநாயகரையும், உண்ணாமுலை அம்மையையும் காப்புச் செய்யுட்களில் துதித்துள்ளபடியால் இது ஒரு வேளை திருவண்ணாமலையில் பாடப்பட்டிருக்கலாம் என்பதும் ஆராய்ச்சிக்குரிய விஷயங்கள்.

கந்தர் அந்தாதி பற்றிய குறிப்புகள் மற்ற சில நூல்களிலும் வருவதை, திருப்புகழ் உரை ஆசிரியர் டாக்டர் வ.சு.செங்கல்வராயப்பிள்ளையவர்கள் மேற்கோள் காட்டியுள்ளார்.

அக்கிளிதான்- வில்லிபுத்தூரான் செவியின் மேலரிவாள்
பூட்டியன்று வல்லபத்தின் வாது வென்று வந்ததுகாண்”

-தணிகை உலா

“எதிரும் புலவன் வில்லி தொழ எந்தை உனக்கந்தாதி சொல்லி ஏழைப்புலவர் செவிக் குருத்தோடெறியுங் கருவி பறித்தெறிந்தே”
-திருமலைமுருகன்

பிள்ளைத்தமிழ் அருணகிரியாரின் கருணைத் திறத்தை எண்ணியே ‘கருணைக்கு அருணகிரி’ என்று கூறும் வழக்கும் எழுந்தது என்கிறார் டாக்டர் பிள்ளையவர்கள்.

ஒரு தென்னைமரத்திலிருந்து பறித்தெடுத்த தேங்காயுள்ளிருக்கும் சுவைமிக்க இளநீரைப் பருகுவதற்காக நாம் மேற்கொள்ளும் சிரமங்கள் எத்தனையோ; அதேபோலத்தான் கடினமான கந்தர் அந்தாதி பதப்பிரிவு கண்டு அயர்ந்துவிடக் கூடாது.அதன் ஆழம் வரைச் சென்று, பொருட்செறிவை அனுபவித்துணர்ந்து, பிறர்க்கு கற்பித்தும் வரும் திருப்புகழ் அடிமை திரு. சு.நடராஜன் போன்ற ஆன்றோரின் உதவியுடன் நாமும் பொருளுணர்ந்து கற்று கந்தர் அந்தாதியை மனனம் செய்வோமேயானால் ஒரு அருட்கவிதையைக் கற்ற நிறைவு நமக்குக் கிட்டும் என்பதில் ஐயமேதுமில்லை.

பி.கு ‘அந்தாதி இல்லா இறைவனுக்கு அந்தாதி’ பாடி வில்லிபுத்தூராரைத் திகைக்கவைத்த அருணை முநிவரின் 54ஆவது அந்தாதிச் செய்யுளின் பதப்பிரிவும் பொருளும் பின்வருமாறு:

திதத்த தத்தித்த திதி தாதை தாத திதத்த தத்தித்த எனும் தாள வரிசைகளைத் தனது நடனம் மூலம் நிலைபெறச் செய்யும் உனது தந்தையாம் பரமசிவனும்

Arunagiri worships Lord Murugan who had just rescued him from certain death by suicide

தாத மறைகிழவோனாகிய பிரமனும்

துத்தி தத்தி தா தித தத்து அத்தி புள்ளிகள் உடைய படம் விளங்கும் பாம்பாகிய ஆதிசேஷனின் முதுகாகிய இடத்தையும், இருந்த இடத்திலேயே நிலைபெற்று ஆனால் அலைகள் வீசுகின்ற திருப்பாற்கடலைத் தனது வாசஸ்தலமாகக் கொண்டு

ததி தித்தித்ததே து ஆயர்பாடியில், தயிர் மிக இனிப்பாக உள்ளதே என்றுகூறி அதை மிகவும் வாரி உண்ட திருமாலும்

துதித்து இதத்து ஆதி – அதை மிகவும் வாரி உண்ட திருமாலும் போற்றி வணங்குகின்ற பேரின்ப சொரூபியான மூலப்பொருளே!

தத்தத்து அத்தி தத்தை தாத தந்தங்களை உடைய யானையாகிய ஐராவதத்தால் வளர்க்கப்பட்ட கிளி போன்ற தேவசேனையின் தாசனே!

திதே துதை பல தீமைகள் நிறைந்ததும்

தாது ரத்தம் மாமிசம் முதலிய சப்த தாதுக்களால் நிரப்பப்பட்டதும்

” A Teashop Owner Couple …Who Have Visited 16 Countries …” !!!

“If you really wish to chase your dreams, nothing can stop you from it,” – a line like this may sound tacky in isolation, but when Vijayan , a 65-year-old wayside tea-seller owning a tiny tea shop in Kochi says it , a decade’s worth of stories echoing hard work, sweat and conquered dreams tumble out.

Tea Shop

Vijayan has been a tea-seller for over forty years, however, that hasn’t stopped him and his wife from touring almost every scenic destination in India along with a whopping 16 other countries- Britain, France, Austria, Egypt, UAE, the list goes on.

His tea-stall is his only source of income, something that has never been an obstacle in fulfilling his dream of travelling all over the world. “I got the obsession in traveling from my dad; he took me to different places since I was 6 year old. We went to Madurai, Palani and many other places. Those travel memories with my dad helped me unleash my dreams” says Vijayan.

Tea Shop 7

Life was not easy on Vijayan while he was growing up. Trips with his father to almost all temples in Kerala triggered his passion for travelling; however his father’s death brought all possibilities of travelling to a standstill as he took up all family responsibilities. It was only in 1988 that he resumed travelling when he accompanied a man as his cook on a pilgrimage to the Himalayas.

What is the point of fulfilling your dreams if you have nobody to share it with, says Vijayan as he refers to his wife Mohana, who joined him forty years ago. Back then her life revolved around Kochi, but post marriage, the couple have explored exotic cities, all on their own. Excitement lights up her face as Mohana explains her most enjoyable journeys.

Tea Shop 4

“I was really excited when we first travelled abroad. Belonging to a very poor family, I never dreamt of a life like this. Later along with him I too became obsessed with the journeys. Switzerland is my favorite among the places we visited”, she says.  Switzerland may have been her favourite but according to her, seeing the statue of Jesus in Israel left her rooted to her spot for a long time.

Tea Shop6

For Vijayan, on the other hand, every experience was different, right from trudging through the deserts of UAE to heading down the magnificent Nile river in Egypt, Nile being one of the spots he wishes to visit again.

It’s hasn’t been easy for the couple to sustain such a lifestyle. With their sole source of income coming from their tea-shop, the only way out for them to pursue their love for travelling was via help through bank loans.

Despite all financial insecurities, the couple would take a loan, travel to a foreign destination, come back and spend the next three years repaying the debt they owed, and the cycle would go on.

Has toiling and working so hard helped him? “There will be many hurdles, but we can overcome that through hard work. If you really wish to chase your dreams, nothing can stop you from it” he says.

Vijayan follows a very simple funda for saving money, “I save rupees 300 a day for our tickets and spend just 10 dollars or less on picking up some tiny souvenirs from the places of visit. We don’t spend anything more.”

There is no question of spending lavishly for this couple.

They may have travelled to 16 countries, but one country on their to-go-list still eludes them – the United States of America, a place they have been wishing to go for a long time now since their last trip to Europe in 2012.

Teah Shop 5

Considering their age, the couple in recent times have faced difficulties in getting loans to finance a loan to their next dream destination. But all is not lost, says Vijayan. “Once I was completely stuck without money, then one of my old acquaintances who resides in South Africa offered me stay and food there. Then I somehow managed the ticket fare and visited the country. So am sure that somehow I will be able to visit the US”, he said.

Tea Shop 3

Despite the financial burden the couple will have to sustain, Vijayan is steadfastly stubborn about one thing, about not leaving his wife behind. “I can’t travel without her, I will happy only when she is around”, says Vijayan smiling.

Some dreams are worth going all out for, and Vijayan’s story sounds like one of those few.

LZ-129 Hindenburg: …Airships Which Ruled The Skies Prior to Airliners !!!

Prior to the age of the airliner, Zeppelin airships ruled the skies over the north Atlantic — connecting cities like New York with Western Europe. Zeppelin’s fleet of airships included such colossal creations like the Graf Zeppelin and the Hindenburg  along with the less famous Graf Zeppelin II.

Before the modern jumbo jet and its first class suites, the biggest and grandest thing in luxury air travel was the German Zeppelin Airship.

Of all the massive Zeppelin’s constructed, the most famous was the Hindenburg. The Hindenburg was designed to ferry passengers across the Atlantic in serenity, with the dirigible floating smoothly through the clouds.

The Hindenburg was the first of two “Hindenburg” Class airships constructed by the Zeppelin Company. Construction of the airship began in 1931 and was completed in 1936. The Hindenburg, along with its highly successful predecessor, the Graf Zeppelin, made numerous trans-Atlantic crossings in their brief but illustrious career.

Constructed out of an aluminum alloy called duralumin, the Hindenburg’s massive frame work was filled with 7 tons of hydrogen. Hydrogen is much lighter than air, and allows the massive Zeppelin to carry more people in greater levels of luxury. However, with an ignition source, an oxidizer, and right concentration, hydrogen can also be incredibly flammable.

The Hindenburg entered passenger service in May of 1936 and carrier up 50 passengers in luxury across the Atlantic.

The legend of the Hindenburg’s luxurious amenities are well know, but most have not seen them in living color. So take the opportunity to check out these wonderful photos of the Zeppelin’s passengers spaces courtesy of airships.net and the German Federal Archive.

” Google’s Internet Balloons Have already Traveled 3 Million Kilometers…” !!!

Google‘s Internet balloons, part of an ambitious experiment called Project Loon to bring web connectivity to remote areas, have cumulatively traveled 3 million kilometers since 2013, the company said Thursday.

Since announcing the project last July, the search giant‘s experimental wing, Google X, has refined the manufacturing process so balloons last 10 times longer—so far, a record of 130 days—in the stratosphere compared with balloons from last year. Furthermore, with automated processes, Google can now launch up to 20 balloons a day. The company is also using computer trajectory simulations to maneuver balloons accurately to their targets.

Google’s made big progress on Project Loon, but it’s not the only company aiming to blanket the world with Internet access. Facebook is also building an army of drones, airplanes, and satellites to bring the web to remote areas lacking Internet infrastructure.

For now, though, take a moment and think about what it means to travel 3 million kilometers:

“That distance would take you around the earth 75 times, or get you to the moon and back nearly 4 times over,” according to Google.
