Why was Sriharikota chosen by ISRO as the launching site of PSLV?


1. Location, Location & Location:
  • Located nearer to the equator, Sriharikota is the ideal launch site for geostationary satellites.
  • Sriharikota is ideal for eastward launches. SHAR’s location on the east coast ensures that it gains an additional velocity of 0.4 km/s due to Earth’s rotation to easily launch rockets. Most satellites are launched eastward. Click & search for eastward to know "Why are most satellites launched eastward?"
  • There is also a proposal for a new launch pad at Kulaseka­ra­pa­ttinam in 2013 which is ideal for southward launches. (refer: ISRO News)
2. Accessibility:
  • Their equipments are huge and travel from across the world. For this very reason, It must be accessible by all means of transport; Land, Air, Water.
  • At the same time, The site is prone for accidents. So, it should be remote away from inhabitants.
  • Being a coastal islandish area with no habitation proves advantageous for Sriharikota because it is on National Highway (NH-5), 20 KM away from nearest Railway Station, and 70 KM (Chennai) from nearest International Ports by air & ships. Can you ask for more?

3. Coastal Site:
  • You never know what falls off from a flying object. The maximum distance of impact from the launch site can be upto 6,500 kms. See the map towards the east of Sriharikota. Need I stress more?


4. Climate:
  • See the chart below? The red horizontal line signifies the temperatures registered in Sriharikota across the year. The blue vertical line represents the rainfall in mm. Heavy rains come only in October and November allowing them to test outdoor for 10 months in an year. There's no bad day than a rain day and Sriharikota offers you optimal rainfall.


It is no accident that Sriharikota is chosen. Sriharikota is not chosen among few options. It is THE OPTION for ISRO. Sriharikota silently played & playing it's role in making India proud ever since the "Rohini-125" sounding rocket was launched in 1971 helping 35/43 successful launches as of June, 2014.

Rare natural phenomenon that occur on earth

Oh Earth you, such a beauty you’re. Your sumptuousness is utterly elusive. Your mesmerizing ways to keep us amused in whatever ways you put up your show is laudable; even for the wrecking destruction that you perform, the aftermath is quite dazzling.
Who doesn’t like the serenity of the earth? Who doesn’t get awestruck looking at the vastness of sheer Godliness that it disseminates? And who doesn’t believe that if there’s magic anywhere in world, it’s right here. Here are some natural phenomena that occur on earth, which will leave you stunned;

Glowing Ocean Neon, Indian Ocean



For years, those who sailed in the Indian Ocean were witnessing a magical and one of a kind sight. All hail the glowing stretches of water. The biological light is the product of marine microbes called phytoplankton.

The Spotted Lake, Canada



This lake contains saline
wikipedia.org

endorheic alkali lake on the eastern side of Similkameen Valley. As the water evaporates from this lake, it leaves behind these eerie holes. Each circle is of different color, due to the variety of minerals found in it.


Fields of Web, Australia



A phenomena so rare, that only occurs only when spiders flee from floodwater or any other catastrophe of similar kind. What they do is leave fields of web. They are then capable of making a big blanket of web on vast fields, even threatening to the habitat nearby.

Zhangye Danxia Landform Geological Park, China



What looks like a painting or a magnificent piece of art, is an actual place in China. The colorful and majestic view is the result of years and years of sediments of mineral deposits and red sandstone. The beauty present is also a collaborative effect of rain and wind that formed valleys, waterfalls, towers, and ravines.

Migration of Monarch Butterfly, United States



Everyone loves butterflies, but imagine a million hovering over your head. These butterflies cannot stand the cold winters of most of the parts of United States and therefore they migrate every autumn to either south or west. They go to Mexico and Southern California, where it remains warm all year long.



Frozen Methane Bubbles, Alaska



These beautiful methane bubbles are alluring and dangerous at the same time. Staying near to them, when popped can cause some serious injuries. These frozen methane bubbles are a beautiful repercussion of dead organic matters, that falls to the bottom, to the delight of bacteria waiting below.


This Storm, Venezuela



This blistering sight occurs in Venezuela. When warm and cold fronts meet where the river empties into Lake Maracaibo, it forms just the right conditions for this phenomenon. Nearby marshes emit methane gas, improving the electrical conductivity of the clouds, which also helps cause these extended lightning strikes which can last 10 hours.

Hair Ice, Wales



Wonder why everything other thing is happening because of bacteria? Well, here’s one more for you. This form of ice is called Haareis or hair ice. This basically happens because of the bacteria pseudomonas syringae. It results in the increased freezing temperature of the water inside the plants, and then when it escapes, it results in this.


Crooked Forest, Poland



As some say, it is because of the extreme queer gravitational pull, however, there are numerous other theories too, totally defying the reason. This forest consist of 400 pine trees, which were planted in the year 1930.


Salar de Uyuni, Bolivia



This beauty, during the rainy seasons, turns itself into a natural mirror. People call it the mirror of the heaven.


Sailing Stones, Death Valley



Racetrack Playa embraces these sailing stones, the ones that have kept the world intimidated by its mere occurrence. There are people who tried figuring out the reason behind this, but failed miserably. Of late, a scientist claims to have the answer, not sure about the credibility though. Some stones are as heavy as 300 kg.




Floating in Dead Sea



If you don’t know how to swim and still want to enjoy the joy of being in the water and this is the place for you. The salt concentration of the Dead Sea fluctuates around 31.5%. This is unusually high and results in a nominal density of 1.24 kg/l. Anyone can easily float in the Dead Sea because of natural buoyancy.



The Blood Rain, Kerela



July 25, 2001 it rained red in Kottayam. It blew everyone’s mind to see red clouds hovering overhead and then the sporadic red rain. It has been a heated debate ever since. Researchers say that it was dust particles from Arabian Desert or exploding material from meteor or from the volcano eruption in Philippine.


Colorful Lakes, Indonesia



These beautiful lakes at the top of Mount Flores, are indubitably a pleasing and startling sight for everyone, which, therefore, remains most visited of all. These lakes are said to change colors. Also known as Kelimutu Lakes, it remained red, blue and white until 2006, but changed the red lake is black-brown, the blue lake becomes light green and the white lake is black.



Fallstreak Hole, New Zealand



A large elliptical gap in the sky that forms when the temperature of the clouds is below freezing point, but the water hasn’t frozen because of Ice nucleation. These ice crystals create a domino effect making them heavier and leaving a hole in the cloud.



Turquoise Ice Laka Baikal



Bearing the crown of largest fresh water lake on the entire planet, Laka Baikal contains 20% of the earth’s fresh water. It has over two thousand varieties of flora and fauna, of which almost 1,600 are endemic to the lake.


Aurora Borealis, Norway



The last, but certainly not the least, this natural phenomenon has won million hearts. Derived from the latin word “sunrise”, aurora borealis is the natural light display in the sky. The reason is charged particles, mainly electrons and protons, entering the atmosphere.

Make your own Earthquake indicator/alarm

If you live in earthquake prone zone and are frightened of the earthquakes coming in the night. Follow this simple trick to make your own Earthquake indicator/alarm.

Stack steel glasses/tumblers on the edge of any table, as shown in the picture.



In the event of an Earthquake, the tumblers will fall down making enough noise to wake you up. And, you can always run for an open and safer place afterwards.

An Austrian town name Fucking.




This is the name of an actual town-in Austria. 

As you might imagine, English speaking tourists have long had a field day stealing the sign, at such inconvenience to the town that a vote was held in 2004 to change its own name. The residents resisted doing so-a memorable quote from the proceedings came from the mayor at the time: "[e]veryone here knows what it means in English, but for us Fucking is Fucking—and it's going to stay Fucking."
So there.
Just to be fair in German the word sounds like 'foo-king'.

Some awesome anagrams

"Listen" ---> "Silent"
"The morse code" ---> "Here come dots"
"Funeral" ---> "Real Fun"
"The detectives" ---> "Detect thieves"
"The earthquakes" ---> "That queer shake"

Some Personalities

The Parasite That Becomes a Tongue

There exists a parasite (Cymothoa exigua) that destroys the tongue of a fish and then replaces the tongue for the rest of its lifespan, essentially transforming into a living, parasitic, but fully functioning and otherwise harmless tongue.



Cool, huh?

How a homeless dead man fooled the Nazi war machinery !!





The allied invasion had not yet begun. Everybody knew the Allies were going to attack but "where" was a big question.

The British came up with Operation Mincemeat.

The idea was to successfully convince the Nazis that the Allies planned to invade Greece and Sardinia. However, the actual invasion was to take place in the island of Sicily, Italy.

Easy? Well, definitely not. This was at the peak of the war. Every information which the was received was scrutinized by both Allies and Axis Powers. They knew spies would leak false information to fool them and they took extra precautions to ensure that any information received was genuine.

The basic plan was to plant important 'classified' documents onto a dead body and somehow ensure that the body is found by the Nazis and also convinces them that the plan was indeed genuine and not an Allied trick.

How was this achieved ?

Research: The British team undertook a research for several months to identify what kind of body would be needed. They had planned to drop the body in the sea and it should appear to the Nazis as if the person had died at sea of drowning and then floated ashore. However, finding such a body was not easy. As the mission was supposed to be extremely secret, there would always be some next-to-kin who wanted to know why they needed the dead body etc.

They finally found their man in the form of a dead man named Glyndwr Michael, who had died after consuming rat poison. As per the coroner, the rat poison did not kill him outright and resulted in more of a slow death. This would lead very little clues for the Nazis who definitely would perform post-mortem to determine the cause of death. To help the cause further, Glyndwr Michael had no known relatives.

The actual dead body of Glyndwr Michael.



Creating an 'identity' for the dead man: This was the most difficult step for the British. They were sure that Nazi spies would do their best to confirm if such a person really existed, what his personal life was, what did he do etc.


The Name: The dead man was given the identity of Captain William 'Bill' Martin. He was given the rank of an 'Acting Major' to convince the Nazis that the dead person was indeed senior enough to be carrying sensitive documents. The name "Martin" was chosen because it was a very common name in the Royal Marines.
Personal Life: William Martin was provided a fiancee named Pam. He would have a photograph of her in his wallet. He carried a love letter and the receipt of a diamond engagement ring.
The Fakes: William Martin also carried, a silver cross, keys, a bus ticket, and a cinema ticket at a local London theater.

Here is a snapshot of the identity card created.



The False Documents: It was ensured that the letter came from the highest level. The document covered several sensitive topics. The letter mentioned about Operation Husky, the invasion of Greece. There was also a letter of introduction for Major Martin. The documents were placed in a briefcase and to ensure that the briefcase is found along with the dead body, it was chained to the body. This also added to the effect that something very important was being carried in the briefcase.

The Disposal of the Body: The body was transferred to British submarine HMS Seraph and at 0430 Hrs on April 30th, a life jacket was placed on the body and let loose. At 0930 Hrs, it was spotted by a local fisherman who took it to local authorities and it eventually reached the Nazis.

I am not sure if the below image is the actual one or just a representation from the movie.




Lot of telegrams were flying between London and Madrid stating - "Recovering the content of the briefcase is a must !!".

The death was reported by the Navy in the Newspapers too.



The Result: Nazis did their necessary checks. They performed the autopsy. The Nazi spies did their investigation in London and checked out the places where Martin had visited and everything panned out perfectly.

Nazis fell for the trap and one of the famous Nazi Generals Erwin Rommel was sent to Greece to assume command.

The British forces attacked Sicily and captured it within five weeks. They encountered little resistance.




Edit (courtesy Phil Darnowsky): After the Nazis fell for this trick, and British intelligence confirmed that the Nazis had read the bunk documents, they sent Churchill a telegram to confirm it. That telegram read: MINCEMEAT SWALLOWED WHOLE.

The Final Resting Place: The grave of Glydwr Michael is currently in the Spanish town of Huelva. The part mentioning the name 'Glyndwr Michael' was added after the war.
