Chandrayaan -2 Payloads Details

Chandrayaan2, India's second mission to moon, is being slated for launch during 2013. Chandrayaan2 will have 
  1. An Orbiter (satellite), 
  2. A Lander and 
  3. A Rover. 
Chandrayaan-2 spacecraft weighs about 2,650 kg at lift-off of which the orbiter weight is about 1,400 kg and lander weight is about 1,250 kg. Chandrayaan-2 is planned to be launched onboard Geosynchronous Satellite Launch Vehicle (GSLV) from Satish Dhawan Space Centre, Sriharikota. While the lander will be provided by Russia, the orbiter and the rover are being built by ISRO.

The five payloads of Chandrayaan-2 orbiter are :

1. Large Area Soft X-ray Spectrometer (CLASS) from ISRO Satellite Centre (ISAC), Bangalore and Solar X-ray Monitor (XSM) from Physical Research Laboratory (PRL), Ahmedabad for mapping the major elements present on the lunar surface.

2. L and S band Synthetic Aperture Radar (SAR) from Space Applications Centre (SAC), Ahmedabad for probing the first few tens of meters of the lunar surface for the presence of different constituents including water ice. SAR is expected to provide further evidence confirming the presence of water ice below the shadowed regions of the moon.

3. Imaging IR Spectrometer (IIRS) from SAC, Ahmedabad for the mapping of lunar surface over a wide wavelength range for the study of minerals, water molecules and hydroxyl present.

4. Neutral Mass Spectrometer (ChACE2) from Space Physics Laboratory (SPL), Thiruvananthapuram to carry out a detailed study of the lunar exosphere.

5. Terrain Mapping Camera2 (TMC2) from SAC, Ahmedabad for preparing a three-dimensional map essential for studying the lunar mineralogy and geology.

The two scientific payloads on Chandrayaan-2 rover are:

1. Laser Induced Breakdown Spectroscope (LIBS) from Laboratory for Electro Optic Systems (LEOS), Bangalore

2. Alpha Particle Induced X ray Spectroscope (APIXS) from PRL, Ahmedabad.
