The Chandrayaan-3, which aspires for a soft landing on the moon’s surface to pave the way for future interplanetary missions, has six payloads that will help ISRO comprehend the lunar soil as well as picture the blue planet from orbit.

During the 14-day journey, the payloads, which include RAMBHA and ILSA, would conduct a number of ground-breaking experiments. They would investigate the moon’s atmosphere and dive beneath its surface to learn more about its mineral composition.
The lunar lander Vikram will photograph the rover Pragyaan while it investigates seismic activity on the moon by dropping sensors. It would attempt to melt a portion of the lunar surface, known as regolith, using laser beams in order to examine the gases produced during the process.

The third lunar expedition in 15 years, Chandrayaan-3, launched from Sriharikota on Friday afternoon and is scheduled to enter lunar orbit on August 5. On the evening of August 23, it will attempt to land on the moon.
“We know that the moon has no atmosphere. However, this is not entirely correct because gases do escape from it. Instead, they become ionised and remain extremely close to the surface. This varies with the time of day and night,” ISRO Chairman S Somanath told PTI. The lander’s Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA) instrument will detect near-surface plasma density and its variations over time.

Mr Somanath explained that the rover will investigate how this tiny environment, atomic atmosphere, and charged particles fluctuate. “This is fascinating. “We also want to know if the regolith has electric or thermal properties,” he added. The Lunar Seismic Activity Instrument (ILSA) will measure seismic activity around the landing site and map the structure of the lunar crust and mantle.

“We will drop an instrument and measure the vibration — what you call’moonquake’ behaviour or internal processes — the movements that are happening there,” stated ISRO chief.

The gentle landing on the lunar surface is scheduled for August 23 at 5:47 p.m. If the mission is successful, India will join the United States, China, and the former Soviet Union as the fourth nation to complete the challenge. When communication with the lander ‘Vikram’ was lost, Chandrayaan-2 was unable to perform the soft landing.
