All you need to know about Chandrayaan-3 mission | The Hindu

After Chandrayaan 1 and 2, the Indian Space Research Organisation (ISRO) is gearing up for its next lunar adventure - Chandrayaan-3. 

Chandrayaan-3 is an upcoming robotic mission by ISRO, designed to land a rover on the moon’s surface. It is largely a repeat of Chandrayaan-2. The spacecraft consists of three main components: a propulsion module, a lander, and a rover. 

The propulsion module will transport the lander and rover to orbit around the moon. It will also continue to orbit the moon, gathering data and relaying signals, while the lander will detach and attempt to land the rover on the lunar surface. 

The Chandrayaan-3 mission will carry a suite of seven advanced scientific instruments to analyse the lunar soil and study the moon’s environment. These instruments will help scientists gather valuable data about the surface, subsurface, and the presence of water ice, which could be crucial for future human missions.

During the soft-landing process, somewhere within a height range of 1.3 KM – 0.8 KM above the lunar surface, Vikram lander would have reached horizontal & vertical speeds of zero m/s causing the lander to hover for 12 secs after which it would descend vertically at 2.0 m/s until it reaches a height of 150 m above the lunar surface where it would hover for additional 22 secs, allowing LHDAC ( Lander Hazard Detection & Avoidance Camera) to scan the lunar surface below for any obstruction, impeding stable landing & carry out a Go-No Go test, if Go, Vikram Lander would descend at 2.0 m/s for a soft landing, if No Go, Vikram Lander would proceed to move in the horizontal direction at 0.5 m/s for another 150 m (max) for LHDAC to again scan the lunar surface below and allow Vikram Lander to descend vertically at 2.0 m/s for a soft landing.
Among the several payloads installed on Pragyaan rover is ILSA (Instrument for Lunar Seismic Activity), i.e., to install a Seismometer that will study lunar quake activity on the south pole which would be occurring due different set of reasons when compared with earth because of the absence of any moving tectonic plates under the lunar crust. The ILSA payload is therefore designed to distinguish and filter out any external lunar quake activity involving collision of lunar surface with asteroids and meteors. This experiment has generated a lot of interest amongst the global space fraternity, especially NASA who have been monitoring lunar quake activity but limited to equatorial sections only. ISRO have set up cost effective communications with Pragyaan rover via Vikram lander, by utilizing existing data transmission set up with the Chandrayaan 3 propulsion unit and using their existing data transmission link with Chandrayaan 2 orbiter as a backup, by inter-linking data transmission between Vikram lander & Chandrayaan 3 propulsion unit with the Chandrayaan 2 orbiter.
ISRO claims it has saved 150 T of fuel due to economy in manoeuvring activity of Chandrayaan 3 propulsion module. 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. Since the additional fuel savings will extend the life of the propulsion module from approx. six months to two years, it would effectively serve more time for detailed study under SHAPE payload.
