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.

India now aims for manned space mission

The plan is to achieve the space mission by 2015 said ISRO chief.

MANNED MISSION: The plan is to achieve the space mission by 2015 said ISRO chief.

India is aiming to send a manned mission into the space after the success of its first unmanned mission to the moon, Indian Space Research Organisation (ISRO) chairmain G. Madhavan Nair said on Nov 23, 2008.

“The (manned) moon mission is a tough task and to achieve that our first task is to send an Indian astronaut on a manned mission to space, who will orbit the earth and return. For this, the sanction of the government has to come.

We plan to achieve this by 2015,” Nair said at a reception accorded to him during his first visit to his home town since the successful launch of the Chandrayaan-1.

“The next moon mission by the US and China is fixed for 2020 and our target is that we also should be ready by then,” Nair added.

“To achieve that, the space mission would provide the necessary boost. Another thing that is being planned is Aditya, a mission to study the solar system from the earth’s orbit,” said Nair.

Indian Flag in moon, Chandrayaan-1 probe sends first signal

Ex-president APJ Abdul Kalam and ISRO Chairman G Madhavan Nair hold a model of the moon.

CONQUERING MOON: Ex-president APJ Abdul Kalam and ISRO Chairman G Madhavan Nair hold a model of the moon.

The moon is 3,84,400 km away from earth and on Nov 14, 2008, India became the fourth nation to have its flag flying on the moon’s surface when Chandrayaan-1’s Moon Impact Probe (MIP), with the Tricolour painted on it, touched down.

The 35-kg payload crash-landed on the lunar surface at around 2030 hrs IST. The MIP has started sending its first signals to Chandrayaan-1.

It also contains equipment which will help scientists design a lunar land rover for the upcoming Chandrayaan-2 mission.

The MIP is slightly smaller than an average TV cabinet. Inside the MIP there is a device to constantly check it’s height as it falls. Another device checks what the air on the moon is made of. There is even a video camera to photograph the moon from close range.

The photographs taken by the MIP will help Indian Space Research Organisation (ISRO) decide where to land India’s first moon rover, a few years from now.

The MIP also has the Indian flag painted on it’s sides and a Sanskrit verse which means “

The MIP disconnected from Chandrayaan-1 100 km above the moon. As it fell, it kept sending information back to the satellite.

Closer to the surface, rockets were fired, to slow down it’s speed and soften the impact on landing.

After half an hour of free fall, the MIP crash-landed on the south pole of moon.

The idea to send a MIP was first mooted by former president Dr APJ Abdul Kalam.

If it weren’t for him, Chandrayaan-1 would only have orbited the moon.

Ganguly batted like a champion: Kris Srikanth

Selection committee chairman Krish Srikkanth showered praise
on Sourav Ganguly on Friday. “He’s really batted like a true champion
right through in his farewell series. He’s put his heart and soul into it. I
feel so happy and proud for him. It’s nice to see him going out on a
high,” Srikkanth told.

Ganguly has set the adrenalin flowing, batting attractively and playing some
crucial knocks in this series while notching up 324 runs at an impressive
average of 64.80.

Perhaps the only tinge of sadness for Srikkanth was to see the Bengal Tiger

getting out when he looked set for a hundred. “I
told Sourav that he’s got to get a hundred in his 100th Test. He was going
great guns but it was God’s will that he ended up 15 runs short. But it was
still an invaluable knock for the team.”

Srikkanth also pointed out that Ganguly played his part in the selection of
Tamil Nadu opener M. Vijay for the final Test match.

“Sourav played with him in the India
A match and he specifically told me, ‘Chika, here is a guy whom you have to
look seriously’. So I took his words seriously because when a player of
Ganguly’s wisdom endorses someone he has to special.”

Vaiko arrested for pro-LTTE remarks

This is the second time that Vaiko has been arrested for supporting the banned group LTTE.
This is the second time that Vaiko has been arrested for supporting the banned group LTTE.
MDMK chief Vaiko was on Thursday arrested for making ‘highly inflammatory speeches in support of the LTTE’, police said.Vaiko had at a public meeting in Chennai on Tuesday said a separate Tamil Eelam under the leadership of LTTE chief Prabhakaran would come into existence soon in Sri Lanka.

“LTTE and Sri Lankan Tamils could not be separated. Though we are against any violence, we should differentiate between violence and right”, he said.

“Prime Minister Manmohan Singh, who had assured me no military aid would be supplied to Sri Lanka, had gone back on his word,” he alleged.

Vaiko said, “if the need arises, I will be the first man to take up arms in support of Sri Lankan Tamils. I will gather youths all over the country for this purpose”.The MDMK presidium chairman, M Kannappan, had told the meeting that time would come to demand for a separate Tamil Nadu. In that meeting, a two-hour film on Sri Lankan army’s alleged atrocities against Tamils was screened.

In a statement on Wednesday, AIADMK chief Jayalalithaa had demanded that all LTTE supporters be booked.

Tamil Nadu government’s decision to arrest Vaiko was to make it clear that ruling DMK’s support was only for the suffering Sri Lankan Tamils and not for LTTE.

Vaiko, now an ally of Jayalalithaa, was detained under POTA by her Government in 2004 on his arrival from the United States after he had made a pro-LTTE speech at a public meeting in Tirumangalam in Madurai.

DMK chief M Karunanidhi had condemned Vaiko’s arrest at that time.

This is the second time that Vaiko has been arrested for supporting the banned group, the earlier occasion being during the previous AIADMK government when he was held under POTA.

Vaiko was arrested under the Unlawful Prevention Activities Act, police said.

He was remanded to 14 days judicial custody.

Vaiko said soon after his arrest that his party was for India’s sovereignty. At the same time, it could not allow the Centre to provide arms and ammunition and logistics support to Sri Lankan government ‘to perpetuate war against Tamils’.

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.

நான் ‘பலிகடா’: கங்குலி ஆவேசம்

பெங்களூரு: “”தேர்வு குழுவினர் என்னை மோசமாக நடத்தினர். இனிமேலும் என்னை பலிகடா ஆக்க வேண்டாம் என்ற எண்ணத்தில் தான் ஓய்வை அறிவித்தேன்,” என்கிறார் கங்குலி. இந்திய அணியின் வெற்றி கேப்டனாக திகழ்ந்தவர் கங்குலி. இவர் ஆஸ்திரேலிய தொடருக்கு பின் சர்வதேச கிரிக் கெட்டில் இருந்து ஓய்வு பெறப்போவதாக திடீரென அறிவித்தார். இதற்கு இந்திய கிரிக்கெட் போர்டின் நிர்ப்பந்தம் தான் காரணம் என கூறப்படுகிறது.

நெருக்கடி கொடுத்தனர்: இந்நிலையில் வெங்சர்க்கார் தலைமையிலான தேர்வு குழுவினர் தன்னை பலிகடா ஆக்கிவிட்டதாக கங்குலி குற்றம் சாட்டியுள்ளார். இது குறித்து அவர் அளித்த பேட்டி: தேர்வாளர்களின் கருணையில் விளையாட வேண்டிய அவசியம் எனக்கு இல்லை. ஒரு தொடருக்கு வாய்ப்பு தருவார்கள். ஆனால், அடுத்த தொடரிலிருந்து நீக்கிவிடுவார்கள். எப்போதும் என்னை தான் “பலிகடா’ ஆக்குகிறார்கள். இது நீடிக்க வேண் டாம் என்ற எண்ணத்துடன் ஓய்வு பெற முடிவு செய் தேன். உங்கள் தலையில் துப்பாக்கியை வைத்தால், அதை எவ்வளவு நேரம் தான் பொறுத்து கொள்வீர்கள். 450 போட்டிகள் விளையாடிய பின்பும் எனக்கு நெருக்கடி கொடுக்கிறார்கள். தூக்கம் வரவில்லை: இரானி கோப்பைக்கான அணியிலிருந்து நீக்கப்படுவேன் என கொஞ்சமும் எதிர்பார்க்கவில்லை. இதனால் ஏற்பட்ட காயம் ஆறவில்லை. சொல்ல முடியாத வேதனை காரணமாக ஒரு மாதம் எனக்கு தூக்கம் வரவில்லை. புதிய தேர்வு குழுவினர் மூன்று ஆண்டுகளுக்கு முன்னரே பொறுப்பேற்றிருந்தால், நிலைமை வேறு மாதிரி இருந்திருக்கும். சிலர் தாங்கள் சேர்த்த ரன்களை விட அதிக முறை “ஹேர் ஸ்டைலை’ மாற்றியுள்ளனர். இவர்களுக்கு அணியில் தொடர்ந்து இடம் அளிக் கப்படுகிறது. சிறப்பாக விளையாடிய போதும் என்னை நீக்கிவிட்டார்கள். எனக்குரிய மதிப்பு கிடைக்கவில்லை. இவ்வாறு கங்குலி தெரிவித்தார்.
