India is all set to launch its first unmanned Moon mission on 22 October - the Chandrayaan-1 (http://www.isro.org/chandrayaan/htmls/home.htm) probe, which will over two years survey our satellite's surface with a rack of hi-res kit.
According to the BBC, the launch had been planned for April, but was knocked back due to "technical problems". The $83m mission involves input from six other countries, including the US. The European Space Agency has contributed three instruments to the total of 11 science payloads (http://www.isro.org/chandrayaan/htmls/psexperiments.htm) on board.
These include the Terrain Mapping Camera (TMC) (http://www.isro.org/chandrayaan/htmls/tmc.htm), designed to "map topography in both near and far side of the Moon and prepare a three-dimensional atlas with high spatial and altitude resolution"; the Lunar Laser Ranging Instrument (LLRI) (http://www.isro.org/chandrayaan/htmls/llri.htm) ("to provide ranging data for determining accurate altitude of the spacecraft above the lunar surface"); and the High Energy X-ray Spectrometer (HEX) (http://www.isro.org/chandrayaan/htmls/hex.htm), which is described as "the first experiment to carry out spectral studies of planetary surface at hard X-ray energies using good energy resolution detectors".
Of course, you can't in all conscience send a spacecraft all the way to the Moon and not throw something at it, so Chandrayaan-1 is offering a piggyback to the 29kg Moon Impact Probe (MIP) (http://www.isro.org/chandrayaan/htmls/mip.htm) destined to, as the name suggests, "impact on the surface".
The means of getting Chandrayaan-1 aloft is India's Polar Satellite Launch Vehicle (http://www.isro.org/chandrayaan/htmls/launch_vehicle.htm), which the Indian Space Research Agency says has "proved its reliability and versatility by scoring eight consecutive successes between 1994-2005 periods in launching multiple payloads".
Of course, as the BBC notes, the project has taken flak for being "over ambitious" and a "waste of resources" for a nation where "millions still lack basic services". Nonetheless, India's highly ambitious space programme includes dispatching a manned mission to the Moon "in the next few years". ®
