Chandrayaan-1 gets down to work

Science - Space

Following the successful deployment of the impactor, India's Chandrayaan-1 moon probe is getting down to work.

Chandrayaan-1 is the first Indian space mission to go beyond Earth orbit.

One November 14, Chandrayaan-1 released the Moon Impact Probe which returned images of the surface as it approached, while the mass spectrometer aboard the impactor obtained information about the extremely thin lunar atmosphere.

The photos were relayed to Earth by the orbiter.

Some of the scientific instruments aboard the orbiter - the terrain mapping camera and the radiation dose monitor - were already functional when the Moon Impact Probe was deployed.

The others are being progressively activated.

The SIR-2 near-infrared spectrometer was commissioned on November 19, and began making serious observations on the following day.

The C1XS - x-ray spectrometer - was activated on November 23, and commissioning work is still in progress.

SARA - the Sub-keV Atom Reflecting Analyser - will be commissioned between December 7 and 10. The protracted process is necessary as scientists will gradually increase the voltage to its high operating level.

Some of the first results from Chandrayaan-1 can be seen on the ISRO web site.
