This is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability

The launch of Chandrayaan-3 has been scheduled for July 13 at 2.30 p.m., officials said on Wednesday.

This is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. It has a lander and rover configuration. Chandrayaan-3 will be launched by the Launch Vehicle Mark-III from the Satish Dhawan Space Centre in Sriharikota and this is scheduled for July 13 at 2.30 p.m., according to the officials.

The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. It has a Spectro-Polarimetry of Habitable Planet Earth payload to study the spectral and polarimetric measurements of Earth from the lunar orbit.

The lander, rover and the propulsion module will have payloads for performing experiments designed to give scientists new insights into the characteristics of earth’s lone natural satellite.

The lander will have four payloads — Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA), Chandra’s Surface Thermo physical Experiment (ChaSTE), Instrument for Lunar Seismic Activity (ILSA) and the LASER Retroreflector Array (LRA). The six-wheeled rover will have two payloads — the Alpha Particle X-ray Spectrometer (APXS) and the LASER Induced Breakdown Spectroscope (LIBS).

In addition to these, there will be one payload on the propulsion module, the Spectro-polarimetry of HAbitable Planet Earth (SHAPE).

The Indian Space Research Organisation (ISRO) plans to retain the names of the Chandrayaan-2 lander and rover for their Chandrayaan-3 equivalents as well.

This means, the Chandrayaan-3 lander will bear the name ‘Vikram’ (after Vikram Sarabhai, the father of the Indian space programme) and the rover, ‘Pragyan’.

Much to its disappointment, the ISRO had lost the Chandrayaan-2 lander-rover configuration and the payloads aboard them after ‘Vikram’ crashed on the lunar surface while attempting a soft landing.
