India’s lunar mission finds evidence of water on the Moon

Dreams of establishing a manned Moon base could become reality within two  
decades after India’s first lunar mission found evidence of large quantities 
of  water on its surface.  
Data from Chandrayaan-1 also suggests that water is still being formed on 
the  Moon. Scientists said the breakthrough — to be announced by Nasa at a 
press  conference today — would change the face of lunar exploration.  
The discovery is a significant boost for India in its space race against  
China. Dr Mylswamy Annadurai, the mission’s project director at the _Indian 
Space Research  Organisation_ (http://www.isro.org/)  in Bangalore, said: “It’
s very satisfying.”  
The search for water was one of the mission’s main objectives, but it was a 
 surprise nonetheless, scientists said.The unmanned craft was equipped with 
 Nasa’s _Moon  Mineralogy Mapper_ (http://m3.jpl.nasa.gov/) , designed 
specifically to search for water by picking up  the electromagnetic radiation 
emitted by minerals. The M3 also made the  unexpected discovery that water may 
still be forming on the surface of the Moon,  according to scientists 
familiar with the mission.  
“It’s very satisfying,” said Dr Mylswamy Annadurai, the project director 
of  _Chandrayaan-1_ (http://www.chandrayaan-i.com/index.php)  at the _Indian 
Space Research Organisation_ (http://www.isro.org/)  (ISRO) in  Bangalore. “
This was one of the main objectives of Chandrayaan-1, to find  evidence of 
water on the Moon,” he told The Times.  
Dr Annadurai would not provide any further details before a news conference 
 at Nasa today from Dr Carle Pieters, a planetary geologist of Brown 
University  who oversaw the M3.  
Dr Pieters has not spoken about her results so far and was not available 
for  comment last night, according to colleagues at Brown University. But her 
results  are expected to cause a sensation, and to set the agenda for lunar 
exploration  in the next decade.  
They will also provide a significant boost for India as it tries to catch 
up  with China in what many see as a 21st-century space race. “This will 
create a  considerable stir. It was wholly unexpected,” said one scientist also 
involved  in Chandrayaan-1. “People thought that Chandrayaan was just 
lagging behind the  rest but the science that’s coming out, it’s going to be 
agenda-setting.”  
Scientists have long hoped that astronauts could be based on the Moon and 
use  water found there to drink, extract oxygen to breathe and use hydrogen 
as fuel.  
Several studies havesuggested that there could be ice in the craters around 
 the Moon’s poles, but scientists have been unable to confirm the 
suspicions.  
The M3, an imaging spectrometer, was designed to search for water by  
detecting the electromagnetic radiation given off by different minerals on and  
just below the surface of the Moon. Unlike previous lunar spectrometers, it 
was  sensitive enough to detect the presence of small amounts of water.  
M3 was one of two Nasa instruments among 11 pieces of equipment from around 
 the world on Chandrayaan-1, which was launched into orbit around the Moon 
in  October last year. ISRO lost control of Chandrayaan-1 last month, and 
aborted  the mission ahead of schedule, but not before M3 and the other 
instruments had  beamed data back to Earth.  
Another lunar scientist familiar with the findings said: “This is the most  
exciting breakthrough in at least a decade. And it will probably change the 
face  of lunar exploration for the next decade.”  
Scientists are eagerly awaiting the results of two American unmanned lunar  
missions, which were both launched in June, that could also prove the 
existence  of water on the Moon.  
Early results from Nasa’s _Lunar Reconnaissance Orbiter_ 
(http://lro.gsfc.nasa.gov/)  (LRO) recorded temperatures as low  as -238C 
(minus 396.4F) in 
polar craters on the Moon, according to the journal  Nature. That makes them 
the coldest recorded spots in the solar system, even  colder than the surface 
of Pluto, and could mean that ice has been trapped for  billions of years, 
the journal said. The LRO has also detected an abundance of  hydrogen, 
thought to be a key indicator of ice, at the poles.  
The other Nasa mission, the _Lunar Crater Observation and Sensing 
Satellite_ (http://lcross.arc.nasa.gov/)   (LCROSS), is due to crash a probe 
into a 
polar crater on October 9 in the hope  of sending up a plume of ice that can 
be examined by telescope.  
“We are on the verge of a renaissance in our thinking about the poles of 
the  Moon, including how water ice gets there,” Anthony Colaprete, principal  
investigator for LCROSS, said in Nature.  
Big bang  
? The Moon is 4.6 billion years old, about the same age as the Earth  
? It is thought to have formed from a giant dust cloud caused when a rogue  
planet collided with the Earth  
? It is 238,000 miles from the Earth  
? Gravity on the Moon is a sixth of that on Earth
