Chandrayaan-3 is a follow-on mission to Chandrayaan-2, developed by the Indian Space Research Organisation (ISRO), to demonstrate end-to-end capability in safe landing and roving on the lunar surface. The mission aims to place a lander and rover on the lunar surface and operate them for roughly one lunar day, or 14 Earth days. The spacecraft consists of a lander and rover configuration, and it will be launched by LVM3 from SDSC SHAR, Sriharikota. The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit. The lander payloads include 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, and 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. The Chandrayaan-3 mission is aimed at the lunar south pole, a region with water ice that could be a source of oxygen, fuel, and water for future moon missions or a more permanent moon colony. If it lands successfully, the Chandrayaan-3 is expected to remain functional for two weeks, running a series of experiments including a spectrometer analysis of the mineral composition of the lunar surface.
