| Goal | The study of the chemical, mineralogical and photogeologic mapping of the Moon | To demonstrate the ability to soft-land and operate a robotic rover on the lunar surface and to study lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice | To demonstrate end-to-end capability in safe landing and roving on the lunar surface. To demonstrate Rover roving on the moon and To conduct in-situ scientific experiments. |
| Lunar landing site | Crash landing near the moon’s south pole, making India the fourth country to place a probe on the lunar surface. | The lander and the rover were scheduled to land on the near side of the Moon, in the south polar region at a latitude of about 70° south | The lander Vikram and the rover Pragyan will be placed on the Moon’s surface in the Manzinus C crater, which is located in the south polar region. |
| Scientific Instruments | Main Satellite 1. Terrain Mapping Camera (TMC) 2. Hyper Spectral Imager (HySI) 3. Lunar Laser Ranging Instrument (LLRI) 4. High Energy X-ray Spectrometer (HEX) 6. Chandrayaan-1 X-ray Spectrometer (CIXS) 7. Near Infrared Spectrometer (SIR-2) 8. Sub Kev Atom Reflecting Analyzer (SARA) 9. Miniature Synthetic Aperture Radar (Mini SAR) 10. NASA’s Moon Mineralogy Mapper (M3) 11. Radiation Dose Monitor (RADOM) Moon Impact Probe (MIP) 1. Radar Altimeter 2. Video Imaging System 3. Chandra’s Altitudinal Composition Explorer (Mass Spectrometer) (CHASE) | S200 solid rocket booster L110 liquid state C25 Upper stage The Chandrayaan-2 mission consisted of three main modules: lunar orbiter Vikram lander (named after Vikram Sarabhai, the late father of India’s space program) lunar rover named Pragyan All of the above parts were developed in India. | Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies. Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site. |
