Chandrayaan-1’s temperature rises, ISRO worried

ISRO Chairman Madhavan Nair says Chandrayaan-1 is hotter by 10 degree Celsius.

FACING THE HEAT: ISRO Chairman Madhavan Nair says Chandrayaan-1 is hotter by 10 degree Celsius.

India’s moon mission Chandrayaan-1 is facing the heat, literally. A month after its launch, an unexplained rise in temperature is causing concern for the Indian Space Research Organisation (ISRO).

ISRO Chairman Madhavan Nair says Chandrayaan-1 is now hotter by 10 degree Celsius which is hot enough to affect its instruments.

Volcanoes have erupted on the moon in the past. And temperatures on the surface often reach 100 degree Celsius.

While it isn’t clear yet what’s triggered the rise in temperature, scientists say a thermal blanket around the satellite could be used to keep temperatures down.

Chandrayaan-1, India’s first lunar mission, was launched on October 22, 2008 from the Satish Dhawan Space Centre, SHAR, Sriharikota by PSLV-C11.

The Moon Impact Probe (MIP), with the Indian Tricolour pasted on its outer surface, was ejected on November 14 from Chandrayaan-1 and landed on the lunar surface.

Chandrayaan-1 in earth’s orbit, sends signals

India’s first unmanned flight to the moon blasted off from Sriharikota, off the Andhra Pradesh coast, early morning on Wednesday and started to cruise around the earth in its designated orbit, minutes after a copybook liftoff.

Carrying over a billion hopes, India’s maiden lunar mission began its historic journey to the moon on Wednesday when an indigenously developed rocket placed the spacecraft into the Transfer Orbit “perfectly”.

A 44-metre-tall and 316-tonne rocket called the Polar Satellite Launch Vehicle (PSLV C11) carried the 1,380-kg lunar orbiter from the Satish Dhawan Space Centre in Sriharikota, , about 80 km north of Chennai, at exactly 0622 hrs IST.

After 18.2 minutes of the lift-off, ISRO’s warhorse rocket injected Chandrayaan-I into earth orbit.

The cuboid spacecraft built by the Indian Space Research Organisation – likely to be injected into Moon’s orbit on November 8 – has launched the country into the elite club that has sent missions to the moon.

Other members of the club are the US, former Soviet Union, European Space Agency, China and Japan. The US returns to lunar exploration aboard Chandrayaan-1, which is also carrying two NASA instruments in its payload.

The first four phases of the launch were 100 per cent perfect, said the scientists, and ground stations across the world – including the master control station in Bangalore – started getting signals from Chandrayaan.

Hectic activity is on at the ISRO Telemetry, Tracking and Command Network (ISTRAC) at Peenya, Bangalore which will be the country’s nerve-centre for controlling Chandrayaan-I for the next two years.

The Deep Space Network (DSN) at Byalalu will join ISTRAC in tracking the spacecraft for the next six hours.

’It’s a historical moment’

Speaking minutes after the successful liftoff Chairman of the Indian Space Research Agency (ISRO) G Madhavan Nair described the moment as historic. “India has started its journey to the moon. The first leg has gone perfectly. the spacecraft has been launched into orbit,” he said.

Nair pointed out that the launch had gone off perfectly despite heavy rain in and around the spaceport for the last four days. “We’ve been fighting the odds for the last four days,” he said.

But the weather gods relented by Tuesday evening and there no rain when the launch took place in a cloudy morning sky.

Chandrayaan-1 started to orbit the earth on its geostationary transfer orbit (GTO), from which its onboard liquid apogee motor (LAM) will be fired in a series of complex manoeuvres to take it to the lunar orbit – 387,000 km from earth – on Nov 8.

It was a dream come true for about 1,000 space scientists and technologists when PSLV-C11, with the spacecraft atop, blasted off from the Satish Dhawan Space Centre of the state-run ISRO.

Within minutes of the 44.4-metre rocket roaring aloft, leaving behind an inferno in the underground inlets of the second launch pad, the mission control centre of the space station erupted with joy and excitement.

Top scientists, led by Nair, space centre director M C Dathan, associate director M Y S Prasad and others shook hands and hugged one another even as the high-security facility reverberated with clapping of hands and cheers.

Former ISRO chairmen U.R. Rao and K. Kasturirangan and space commission member Roddam Narasimaiah, who were present on the occasion, congratulated Nair and his team.

A Letter to Every Indian – Dr. APJ. Abdul Kalam

A Letter to Every Indian – APJ

APJ Abdul Kalam at SpeechThe President of India DR. A. P. J. Abdul Kalam ‘s Speech in Hyderabad .
Why is the media here so negative?
Why are we in India so embarrassed to recognize our own strengths, our achievements?
We are such a great nation. We have so many amazing success stories but we refuse to acknowledge them. Why?
We are the first in milk production.
We are number one in Remote sensing satellites.
We are the second largest producer of wheat.
We are the second largest producer of rice.
Look at Dr. Sudarshan , he has transferred the tribal village into a self-sustaining, self-driving unit. There are millions of such achievements but our media is only obsessed in the bad news and failures and disasters.
I was in Tel Aviv once and I was reading the Israeli newspaper. It was the day after a lot of attacks and bombardments and deaths had taken place. The Hamas had struck. But the front page of the newspaper had the picture of a Jewish gentleman who in five years had transformed his desert into an orchid and a granary. It was this inspiring picture that everyone woke up to. The gory details of killings, bombardments, deaths, were inside in the newspaper, buried among other news.

APJ Abdul Kalam at Speech1In India we only read about death, sickness, terrorism, crime.. Why are we so NEGATIVE? Another question: Why are we, as a nation so obsessed with foreign things? We want foreign T.Vs, we want foreign shirts. We want foreign technology
Why this obsession with everything imported. Do we not realize that self-respect comes with self-reliance? I was in Hyderabad giving this lecture, when a 14 year old girl asked me for my autograph. I asked her what her goal in life is. She replied: I want to live in a developed India . For her, you and I will have to build this developed India . You must proclaim. India is not an under-developed nation; it is a highly developed nation.
Do you have 10 minutes? Allow me to come back with a vengeance.

Got 10 minutes for your country? If yes, then read; otherwise, choice is yours.
YOU say that our government is inefficient.
YOU say that our laws are too old.
YOU say that the municipality does not pick up the garbage.
YOU say that the phones don’t work, the railways are a joke. The airline is the worst in the world, mails never reach their destination.
YOU say that our country has been fed to the dogs and is the absolute pits.

YOU say, say and say. What do YOU do about it?
Take a person on his way to Singapore. Give him a name – ‘YOURS’. Give him a face – ‘YOURS’. YOU walk out of the airport and you are at your International best. In Singapore you don’t throw cigarette butts on the roads or eat in the stores. YOU are as proud of their Underground links as they are. You pay $5 (approx. Rs. 60) to drive through Orchard Road (equivalent of Mahim Causeway or Pedder Road) between 5 PM and 8 PM. YOU come back to the parking lot to punch your parking ticket if you have over stayed in a restaurant or a shopping mall irrespective of your status identity… In Singapore you don’t say anything, DO YOU? YOU wouldn’t dare to eat in public during Ramadan, in Dubai . YOU would not dare to go out without your head covered in Jeddah.
YOU would not dare to buy an employee of the telephone exchange in London at 10 pounds (Rs.650) a month to, ‘see to it that my STD and ISD calls are billed to someone else.’YOU would not dare to speed beyond 55 mph (88 km/h) in Washington and then tell the traffic cop, ‘Jaanta hai main kaun hoon (Do you know who I am?). I am so and so’s son. Take your two bucks and get lost.’ YOU wouldn’t chuck an empty coconut shell anywhere other than the garbage pail on the beaches in Australia and New Zealand .
Why don’t YOU spit Paan on the streets of Tokyo? Why don’t YOU use examination jockeys or buy fake certificates in Boston??? We are still talking of the same YOU. YOU who can respect and conform to a foreign system in other countries but cannot in your own. You who will throw papers and cigarettes on the road the moment you touch Indian ground. If you can be an involved and appreciative citizen in an alien country, why cannot you be the same here in India?

APJ Abdul Kalam at Speech2In America every dog owner has to clean up after his pet has done the job. Same in Japan.
Will the Indian citizen do that here?’ He’s right. We go to the polls to choose a government and after that forfeit all responsibility.
We sit back wanting to be pampered and expect the government to do everything for us whilst our contribution is totally negative. We expect the government to clean up but we are not going to stop chucking garbage all over the place nor are we going to stop to pick a up a stray piece of paper and throw it in the bin. We expect the railways to provide clean bathrooms but we are not going to learn the proper use of bathrooms.
We want Indian Airlines and Air India to provide the best of food and toiletries but we are not going to stop pilfering at the least opportunity.
This applies even to the staff who is known not to pass on the service to the public.

APJ Abdul Kalam Wings of fire

When it comes to burning social issues like those related to women, dowry, girl child! and others, we make loud drawing room protestations and continue to do the reverse at home. Our excuse? ‘It’s the whole system which has to change, how will it matter if I alone forego my sons’ rights to a dowry.’ So who’s going to change the system?
What does a system consist of? Very conveniently for us it consists of our neighbours, other households, other cities, other communities and the government. But definitely not me and YOU. When it comes to us actually making a positive contribution to the system we lock ourselves along with our families into a safe cocoon and look into the distance at countries far away and wait for a Mr.Clean to come along & work miracles for us with a majestic sweep of his hand or we leave the country and run away.
Like lazy cowards hounded by our fears we run to America to bask in their glory and praise their system. When New York becomes insecure we run to England . When England experiences unemployment, we take the next flight out to the Gulf. When the Gulf is war struck, we demand to be rescued and brought home by the Indian government. Everybody is out to abuse and rape the country. Nobody thinks of feeding the system. Our conscience is mortgaged to money.

Dear Indians, The article is highly thought inductive, calls for a great deal of introspection and pricks one’s conscience too…. I am echoing J. F. Kennedy’s words to his fellow Americans to relate to Indians…..
‘ASK WHAT WE CAN DO FOR INDIA AND DO WHAT HAS TO BE DONE TO MAKE INDIA WHAT AMERICA AND OTHER WESTERN COUNTRIES ARE TODAY’
Lets do what India needs from us.
