<<<India 'over the moon' with water discovery
By Naseeb Chand (AFP) – 1 hour ago
BANGALORE, India — India on Friday hailed the discovery of water on the moon as a triumph for a lunar programme that is aiming to cement its reputation as a serious player in the space industry.
The mood in India's space community has gone from glum disappointment last month when its Chandrayaan-1 satellite mission was prematurely aborted to jubilation with news of a major discovery.
"India should be proud that Chandrayaan discovered water on the moon," said a smiling G. Madhavan Nair, chief of the Indian Space Research Organisation (ISRO), at a press conference to discuss the findings. "It has done a wonderful mission, it has not failed. It is 110-percent successful."
In one of the three papers published in the latest edition of the journal Science on Thursday, researchers said they had analysed light waves detected by NASA-made instruments on board the Indian satellite and two other probes.
The reflected light waves showed a chemical bond between oxygen and hydrogen -- proof, the researchers said, of the existence of water on the moon's surface.
Until now, scientists had advanced the theory that, except for the possibility of ice at the bottom of craters, the moon was totally dry.
The water discovery was gleaned from data collected before the Chandrayaan mission was aborted.
And there could also be more to come from India's space agency once massive amounts of data beamed back to the national space centre in Bangalore are analysed, Nair added.
"We had very dramatic moments in this mission starting from its launch onwards, but I am happy to say that the volume of data collected has been phenomenal," he said. "It has filled the computers in ISRO as well in NASA."
India launched Chandrayaan and fired a probe onto the moon's surface late last year in an event that the national space agency hoped would bring it international recognition.
The probe's landing vaulted India into the league of space-faring nations led by the United States and regional neighbours Russia, China and Japan, and was seen as a symbolic and proud moment in the country's development.
But there was initial disappointment last month when Chandrayaan lost contact with its controllers and the mission was aborted only 10 months into a planned two-year mission.
Indian newspapers headlined their front pages with news of the discovery on Friday and cable television included discussions of the event marked by thinly disguised patriotic fervour.
"One Big Step For India, A Giant Leap for Mankind," said The Times of India. "Water on moon: Chandrayaan's stunning find," headlined the Hindustan Times.
The mission cost 80 million dollars, less than half the amount spent on similar expeditions by other countries, and India is keen to use its cost advantage to capture a large slice of the satellite business.
The euphoria over Chandrayaan came on top of celebrations over India's successful launch Wednesday of seven satellites -- six of them foreign -- in a single mission.
India began its space programme in 1963, developing its own satellites and launch vehicles to cut dependence on overseas agencies.
The latest discovery was made possible by US-made technology, however.
The NASA-developed "Moon Mineralogy Mapper," or M3, is a high-tech scanner that tracks the reflection of sunlight off the moon's surface to determine soil composition.
The new research used input from two other probes equipped with M3-type instruments, which also detected the chemical signature for the presence of water.
The American spacecraft Cassini passed near the moon a decade ago on its way to Saturn, while a third probe, also American, called Deep Impact, was launched toward the comet Tempel-1 in 2005 to pierce it with a projectile in order to analyse the dust cloud created by the impact.
Deep Impact passed near the moon to gather data with an instrument similar to M3.
The new data came just two weeks before a NASA probe is to crash into the surface near the moon's southern pole to see if water can be detected in the dust and debris released by the impact.

You'd have thunk that they would have spotted this in the 60's....
No, the poles were not mapped or examined properly in the 1960s. Most of the surveying of the moon caried out in the 60s was part of the anticipated manned landings and therefore confined to the equatorial belt of the moon which is where the manned landing were restricted to. None of the rocks brought home by the Apollo astronauts showed any indication that they had ever been exposed to water - except for one small sample which they assumed had been contaminated in the lab.Some indications of water on the moon were discovered in the mid 1990s but this is the strongest evidence yet.

have i missed something, don't we send several million a year to india in aid, but they are raking money in launching satellites for other countries, and launching their own space probes.
or am i being a little picky with their priority list?
See the other thread on aid to India for a good explanation of this.or am i being a little picky with their priority list?

This so called 'aid' goes to NGO's usually British charities which have some stake in the Labour party. None of it goes to the Indian government. For information the Indian space programme pays for itself. Yesterday it launched a fisheries and cyclone monitoring satellite which will enable conservation of fish stocks as well as enable cyclone warnings so fishermen (who are usually poor) don't get killed. Much of this satellite launch was paid for by launching 6 other foreign satellites as well. The commercial arm of the ISRO which is ANTRIX also sells a lot of the imagery that the satellites especially the remote sensing ones have. So it's not UK aid that is paying for this, despite what some people might claim that it pays for like Nuclear submarines, nuclear weapons, etc. Of course India has social problems but the space programme is not a waste of money. Satellites have enabled remote surgery as well as remote learning programmes. Villages which were once remote outposts now have access to e-learning and online medical information.
BTW the probe also carried a X-ray Spectrometer (C1XS) from Rutherford Appleton Laboratory, so some of it's success was British but don't let that bother anyone...
