What are the main objectives of Chandrayaan-3? Only the United States, Russia, and China have successfully landed a spacecraft on the lunar surface; India‘s Chandrayaan 3 mission will attempt this feat.
A month after launch, the Chandrayaan-3 spacecraft will enter lunar orbit.
On August 23, the lander Vikram and the rover Pragyaan are anticipated to touch down on the moon.
What are the main objectives of Chandrayaan-3?
From Sriharikota’s Satish Dhawan Space Centre, Chandrayaan-3 was sent into orbit by the LVM3 rocket.
The lander and rover combination will travel into orbit and be propelled to a 100-kilometer lunar orbit once there.
After that, the lander will detach from the propulsion module and make an attempt at a soft landing on the moon’s surface.
The Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload, which analyses Earth’s light to determine its spectral and polarimetric features, is also carried by the propulsion module.
The Chandrayaan-3 project will try to land a spacecraft on the moon and send out a rover to investigate the lunar surface.
It is a follow-up to the Chandrayaan-2 mission. The moon’s composition and geology will be studied by the rover, which will provide scientists with more information about the moon’s past and present.
S Somanath, the chairman of ISRO, spoke about how the space agency has changed in order to increase the chances that the Chandrayaan-3 mission will succeed in an interview with NDTV.
“The main lacuna in the last Chandrayaa-2 mission was that there were off-nominal conditions that were initiated in the system. Everything was not nominal. And the craft was not able to handle the off-nominal condition for a safe landing,” he said.
Chandrayaan-3 will perform scientific experiments to learn more about the moon’s environment, including its history, geology, and potential for resources, in addition to its primary objective of landing a spacecraft there.
Six payloads are being carried by Chandrayaan-3 in order to examine the lunar surface and take pictures of Earth from the lunar orbit.
Chandrayaan-3, employing its payloads RAMBHA and ILSA, will carry out a number of ground-breaking experiments over the course of its 14-day mission (one lunar day) after landing. These investigations will explore the moon’s surface to learn more about its mineral makeup as well as its atmosphere.
The moon rover Pragyaan, which will deploy its instruments to measure seismic activity there, will be photographed by the lander Vikram.
The lunar regolith will be melted by Pragyaan’s laser beams, and the gases released in the process will be analyzed.
India will gain access to a lot of information on the lunar surface as well as its potential for future human habitation through this mission.
A region close to the equator is more likely to be appropriate for human settlement, according to ISRO director S. Somnath.
“I don’t know that aspect very well – which is the best place for human beings to go. You are talking from the point of view of the availability of water and that is possibly one aspect. Today, one of the important requirements is temperature excursions (deviations) as well as the availability of solar power for power generation. From that point, an equatorial location could be more ideal for human beings to settle, if at all a human habitat has to be built,” he said.
The Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA) payload will measure changes in the density of charged particles near the lunar surface.
The Laser-Induced Breakdown Spectroscope (LIBS) will ascertain the elemental content of lunar soil, while the Alpha Particle X-Ray Spectrometer (APXS) will measure the chemical composition and infer the mineralogical composition of the moon’s surface.
Before sunset, Chandrayaan-3 will launch its lunar lander to the moon’s south pole at 70 degrees latitude in order to avoid the -232 degrees Celsius nighttime temperatures on the moon.
The spacecraft will land on the lunar surface at 5:47 pm on August 23.
