Payloads of Chandrayaan-I

There are 11 payloads of which 5 are Indian, 3 of ESA, 2 of United States and 1 is from Bulgaria.

The 5 Indian ones are

  1. Terrain Mapping Camera (TMC): For complete mapping of moon topography.
  2. Hyperspectral Imager (HySI): a CCD camera designed to obtain the spectroscopic data for mapping of minerals on the surface of the moon as well as for understanding the mineralogical composition of the moon's interior
  3. Lunar Laser Ranging Instrument (LLRI): To provide necessary data for determining the accurate altitude of Chandrayaan-1 spacecraft above the lunar surface. To determine the global topographical field of the Moon as well as to generate an improved model for the lunar gravity field.
  4. High Energy X-ray Spectrometer (HEX): 1st planetary experiment to carry out spectral studies at 'hard' X-ray energies using good energy resolution detectors. Designed to help explore the possibility of identifying polar regions covered by thick water-ice deposits as well as to identify regions of high Uranium and Thorium concentrations.
  5. Moon Impact Probe (MIP):To demonstrate the technologies required for landing a probe at the desired location on the moon.

Other payloads
  1. Chandrayaan-1 Imaging X-ray Spectrometer (C1XS): This instrument intends to carry out high quality mapping of the moon using X-ray fluorescence technique for measuring elemental abundance of Magnesium, Aluminium, Silicon, Iron and Titanium distributed over the surface of the moon.
  2. Smart Near Infrared Spectrometer (SIR-2): This instrument aims to study the lunar surface to explore the mineral resources, the formation of its surface features, the way different layers of the moon's crust lie over one another and the way materials are altered in space.
  3. Sub keV Atom Reflecting Analyser (SARA): The aim of this instrument is to study the surface composition of the moon, the way in which moon's surface reacts with solar wind, the way in which surface materials on the surface of the moon change and the magnetic anomalies associated with the surface of the moon.
  4. The Bulgarian 1
    Radiation Dose Monitor (RADOM):
    This instrument aims to qualitatively and quantitatively characterise the radiation environment in space around the moon’s vicinity. It will help study the radiation dose map of space near the moon at various latitudes and altitudes.
  5. Nasa's 2
    Mini Syntheic Aperture Radar (MiniSAR):
    This is one of the two scientific instruments of the United States flown in Chandrayaan-1 mission
  6. Moon Mineralogy Mapper (M3): This is an imaging spectrometer which is intended to assess and map lunar mineral resources at high spatial and spectral resolution to support planning for future targeted missions.

The goals of Chandrayaan-I

Primarily, Chandrayaan-I is dedicated
1. To know more about the moon
2. To improve Indian technology
3. To provide chances in planetary research for young Indian Scientists

These will be met through high resolution remote sensing of the moon in the visible, near infrared, microwave and X-ray regions of the electromagnetic spectrum. With this, preparation of a 3-dimensional atlas of the lunar surface and chemical mapping of entire lunar surface is envisaged.

Thanks to ISRO

How to become the center of attraction

It is human nature to yearn for attention. But everyone is certainly not going to be successful in this very particular case, just as there can't be two lions in a single pride. Now there are many ways to make people listen to you. But attention must be bought. It can't automatically come to you without you doing something. Now keep in mind these things:

  • The world is a mirror. It gives you back whatever you give it. So to earn attention, you will have to pay it too.

  • The best way to have people around you and the best way to have friends around you is the same: befriend who is around you. And the best way to make friends is to talk. Talk something. Anything. Words have a magical touch. As the graviton pulls the body it reaches to the body it left, words attract people to the one who lets out them and bind them with emotional gravity to the speaker. Therefore to have people glued around you, always talk something so that if they go away, they would miss something.

  • Don't show that you are eager to receive attention. But unobtrusively, start gaining attention.

  • One thing you will have to certainly avoid from your life is skipping chances. There can be no other thing as agonizing as a wasted opportunity. If you get a chance to perform, do it then and there. Hesitate for a moment and it's lost. There's no way you can buy back the chance, and almost surely the same chance will not come to you again.

  • Keep smiling. Ha! This one. It's sure gonna be a grand success. Unless there are around you people who are very nice that they hate smiling people, you're always gone to be admired if you keep a smiling face 24/7. Now the only problem is you will have to widen your mouth a little extra than your natural pose to smile to a person.

  • Always be frank. There is no quality better than frankness that's going to attract people. Be ready to admit mistakes. Do tell out loud the silly mistake that you committed. Because, if you try to hide up, and if someone had seen it, then there's no way that you can roll out of the issue. Honesty is the best policy.

Best of luck

Self Confidence and Attitude

A story that I got from Success does not come in a day community in Orkut. Thanks to the TS Duttkumar

A business executive was deep in debt and could see no way out. Creditors were closing in on him. Suppliers were demanding payment.

He sat on the park bench, head in hands, wondering if anything could save his company from bankruptcy.

Suddenly an old man appeared before him.

"I can see that something is troubling you," he said. After listening to the executive's woes, the old man said, "I believe I can help you."

He asked the man his name, wrote out a cheque, and pushed it into his hand saying, "Take this money. Meet me here exactly one year from today, and you can pay me back at that time." Then he turned and disappeared as quickly as he had come.

The business executive saw in his hand a check for $500,000, signed by John D. Rockefeller, then one of the richest men in the world!

"I can erase my money worries in an instant!" he realized. But instead, the executive decided to put the un-cashed check in his safe. Just knowing it was there might give him the strength to work out a way to save his business, he thought.

With renewed optimism, he negotiated better deals and extended terms of payment. He closed several big sales. Within a few months, he was out of debt and making money once again.

Exactly one year later, he returned to the park with the un-cashed check.

At the agreed-upon time, the old man appeared. But just as the executive was about to hand back the check and share his success story, a nurse came running up and grabbed the old man.

"I'm so glad I caught him!" she cried. "I hope he hasn't been bothering you. He's always escaping from the rest home and telling people he's John D. Rockefeller. "

And she led the old man away by the arm.

The astonished executive just stood there, stunned. All year long he'd been wheeling and dealing, buying and selling, convinced he had half a million dollars behind him.

Suddenly, he realized that it wasn't the money, real or imagined, that had turned his life around. It was his newfound self-confidence that gave him the power to achieve anything he went after.

Have faith in your self as only that counts.

Aren't we naturally immune to HIV?

Our immune system can ward off almost all the diseases that catch human beings. But what about HIV? Why can't we keep off it too? Are the yogis immune to HIV?
All of these questions bring us to one answer - "We were immune to HIV." There is an enzyme called APOBEC - 3G that can fight HIV by stopping the virus from replication. But why are millions dying?
Because HI Virus has improved itself. It has evolved so as to have a code which produces the protein Vif called "virulence factor". This Vif attaches with APOBEC -3G so that the focus of our enzyme is lost and at the very same moment, HIV gets inside. The watch dog is done with, there is nothing to fear.
But research has begun to find whether or not we can benefit from this body mechanism.

Wikibooks - books of the future

It's just a fascinating idea. A book. An ebook. That can be edited by anyone, anywhere, anytime. And a collection of these, available at a website. Only wikimedia can do that.
The concept which I believe has been conveyed by now is one of the best merits that internet has brought to human beings. No writer may be complete by himself. But the latest form of literature removes that problem - of the incompleteness.

So, to read complete books, go to wikibooks

Why we do what we do

There was nothing...

Then, there was a point...
It was infinitely heavy.

It started expanding...
Matter started to get its physical laws.

Dust particles condensed.
Condensed dust particles joined.
Joined condensed dust particles grouped.
Galaxies were formed.

Galaxies meant lot of stars.
Lot of stars meant lot more celestial bodies other than the glowing bodies.
It meant lot of planets.
Lot of planets meant different planets.
Different planets meant different conditions.
Different conditions meant different environments.

And there was one galaxy called Milky Way.
There was one star called Sun.
There was one planet called Earth.
It had a different environment.

There was a spontaneous creation of Organic molecules.

There was changes in the environment.
There was an urge in the Organic molecules to live - (THE SECRET OF LIFE)
There was adaptation.
There was evolution...

Because it was at a distance not too far and not too near to sun - the temperature was optimum for liquid water;
Because its size was not too large, and therefore gravity was not so large to make water solid;
Because its size was not too small, its atmosphere was not too thin, so water could not be dried;

Because there were large amounts of oxygen present in the seas as compounds that gradually gased out;

Life could exist...

Evolution continued...
Organisms became complex.
Porifera
Coelenterata
Platyhelminthes
Nemotoda
Arachnida
Arthropoda
Mollusca
Echinodermata
Protochordata
Vertebrata

And in the last type of organisms, there was man.
He was a fool.
He learned hunting.
He learned cooking.
He learned making tools.
He learned agriculture.
He found out wheels.
He found out steam.
He found out uranium...
He explored...
He implored...

He made divisions.
He made countries.
He made laws.
He broke them.
He waged wars.
He killed.
He gave birth (or She?)
He lived...

He found out why for 12 hours he could see everything, but for another 12 hours he couldn't without electricity.
He found out why paper burnt...

He found out how to talk.
He found out how to talk with people metres away.
He found out how to talk with people kilometres away.
He found out how to talk with people countries away.
He found out how to talk with people planets away...

He found out why he was like his father and mother.

He found out that he wanted to find out everything.
He found out that he wanted to survive.
But he couldn't find why.
He couldn't find why he thought what he thought.
He couldn't find why he did what he did.

He can never find it.
Because it is the SECRET OF LIFE.
It is a secret of the nature.
And nature stores secret with an encryption no hacker can hack.

Two way mirrors in changing rooms

There are some mirrors which allow to see through on one side while seeming like a mirror on the other side (Seen it in any James Bond film?). These may be very useful when you build your house. But when these kinds of glasses are kept in improper places, you may be being cheated. There might be someone behind you watching you. So how do you know whether you are watching into a genuine mirror or a mirror-cum-glass one?
I would be cheating if I put the solution here, because I got this from another blog. So I will post the link : Bioinformatiz

Xenophobia

OK. You've heard that term too many times. But still doesn't know the meaning quite exact, right?

Now here it is
Xenophobia is an intense and/or irrational dislike and sometimes fear of people from other countries. It comes from the Greek words ξένος (xenos), meaning "foreigner," "stranger," and φόβος (phobos), meaning "fear." The term is typically used to describe a fear or dislike of foreigners or of people significantly different from oneself.

AIDS spreading in new ways

FROM Arvind Khamitkar , I.A.S, Director of Medical & Research Div, Chennai
Dear Friends,
A few weeks ago, in a movie theatre, a person felt something poking from her seat. When she got up to see what it was, she found a Needle sticking out of the seat with a note attached saying
'You have just been infected by HIV'.
The Disease Control Center (in Paris ) reports many similar events in many other cities recently. All tested needles were HIV Positive. The Center also reports that needles have been found in cash dispensers at public banking machines. We ask everyone to use extreme caution when faced with this kind of situation. All public chairs/seats should be inspected with vigilance and caution before use. A careful visual inspection should be enough. In addition, they ask that each of you pass this message along to all members of your family and your friends of the potential danger.
Recently, one doctor has narrated a somewhat similar instance that happened to one of his patients at the Priya Cinema in Delhi ... A young girl, engaged and about to be married in a couple of months, was pricked while the movie was going on. The tag with the needle had the message 'Welcome to the World of HIV family'.
Though the doctors told her family that it takes about 6 Months before the virus grows strong enough to start Damaging the system and a healthy victim could survive about 5-6 years,the girl died in 4 months, perhaps more because of the 'Shock thought'. We all have to be careful at public places, rest God help! Just think about saving a life by forwarding this message. Please, take a few seconds of your time to pass along.
With Regards, Arvind Khamitkar, I.A.S, Director of Medical & Research Div, Chennai.
Kindly pass this to every one. Probably your mail can help some save his/her life
