One key objective will be to search for surface or sub-surface water-ice on the Moon, especially at the poles.One key objective will be to search for surface or sub-surface water-ice on the Moon, especially at the poles.
Another will be to detect Helium 3, an isotope which is rare on Earth, but is sought to power nuclear fusion and could be a valuable source of energy in future.Another will be to detect Helium 3, an isotope which is rare on Earth, but is sought to power nuclear fusion and could be a valuable source of energy in future.

"Chandrayaan has a very competitive set of instruments... it will certainly do good science," said Barry Kellett, project scientist on the C1XS instrument, which was built at the Rutherford-Appleton Laboratory in the UK."Chandrayaan has a very competitive set of instruments... it will certainly do good science," said Barry Kellett, project scientist on the C1XS instrument, which was built at the Rutherford-Appleton Laboratory in the UK.

Researchers say the relative abundances of magnesium and iron in lunar rocks could help confirm whether the Moon was once covered by a molten, magma ocean.Researchers say the relative abundances of magnesium and iron in lunar rocks could help confirm whether the Moon was once covered by a molten, magma ocean.
"The iron should have sunk [in the magma ocean], whereas the magnesium should have floated," Mr Kellett told BBC News."The iron should have sunk [in the magma ocean], whereas the magnesium should have floated," Mr Kellett told BBC News.
"The ratio of magnesium to iron for the whole Moon tells you to what extent the Moon melted and what it did after it formed.""The ratio of magnesium to iron for the whole Moon tells you to what extent the Moon melted and what it did after it formed."
The instrument will look for more unusual elements on the Moon's surface, such as titanium. This metallic element has been found in lunar meteorites, but scientists know little about its distribution in the lunar crust.The instrument will look for more unusual elements on the Moon's surface, such as titanium.

Chandrayaan will also investigate the differences between the Moon's near side and its far side. The far side is both more heavily cratered and different in composition to the one facing Earth.Chandrayaan will also investigate the differences between the Moon's near side and its far side.

Chandrayaan will slip into a near-circular orbit at an altitude of 1,000km. After a number of health checks, the probe will drop its altitude until it is orbiting just 100km above the lunar surface.Chandrayaan will slip into a near-circular orbit at an altitude of 1,000km.

India, China, Japan and South Korea all have eyes on a share of the commercial satellite launch business and see their space programmes as an important symbol of international stature and economic development.India, China, Japan and South Korea all have eyes on a share of the commercial satellite launch business and see their space programmes as an important symbol of international stature and economic development.

I think the Indian moon mission is a tremendous achievement and testimony to the nations intellectual prowess. All arguments that a nation of millions of poor hungry people should not invest millions into space missions are bogus - the Indian space program is self sustaining and profit making! If India is not to invest a dime in space research then why should we invest a dime on a single computer?
