On 14 July 2023, the space agency of India, ISRO (Indian Space Research Organization), made a soft landing on the Moon with its expected satellite of Earth to kick off the launch of the Chandrayaan-3 lunar mission to examine and observe the Moon. The prime purpose of the third mission of the Chandrayaan-3 is the discovery of space and innovation by building on the accomplishments of its forerunners, which is Chandrayaan-1 and Chandrayaan-2. On the day of launching, Chandrayaan-3 takes off from the Satish Dhawan Space Centre which is located in Andhra Pradesh perched on a GSLV-MK III (Geosynchronous Satellite Launch Vehicle Mark III) bulky-lift rocket, just below the launch of Chandryaan-2 after 4 years. The mission is an admirable illustration of India's increasing dedication to strengthening its position in the international space community around the world.

Third India’s Celestial mission, Chandryaan-3 includes collaboration and alliance with a distinguished type of space agencies that involves Australian, European, and United States (US) matching part of ISRO. The latest mission of Chandryaan-3 is a sequence of ISRO’s “Moon Craft” Celestial mission which will determine the various new innovative technologies that are essential for astronomical space flight and the major goal is to accomplish the first soft landing of India on different lunar bodies.

As per the Indian Space Research Organization (ISRO), the mission Chandryaan-3 has three prime objectives which include:

  • To Demonstrate or establish a soft and safe landing on the surface of Lunar.
  • To conduct a rover rambling on the moon
  • To conduct on-site/in-site several experiments on the Celestial surface.

The most significant purpose of the establishment of Chandryaan-3 is that when the mission of Chandrayaan-2 successfully landed on the Vikram lander and Pragyan rover close to the Moon's South Pole in 2019, it grabbed everyone's attention all over the world. But there were some kinds of negligible difficulties in the attempt. At the time, of trying to land on the moon, the Vikram lander from Chandrayaan-2 has been crashed. Despite the incident, even so, signified a major accomplishment in the space history of India. Apart from that, selecting July month for the launch of lunar mission Chandryan-3, the prime reason behind is the closeness between Moon and Earth.

Candryaan-3 encompasses three foremost components that involve:

The Module of Propulsion: This propulsion module will transmit the rover configuration and lander till 100 km Celestial orbit. It looks like a box structure with one big solar panel straddling 1 side and a big cylinder at the top that performs as a mounting construction for the overall lander. Along with that, this propulsion module transmits a payload which is known as Spectro-polarimetry of Habitable Planet Earth (SHAPE) to examine the polarimetric and spectral dimensions of Earth from the Celestial orbit.

Lander: The lander is majorly accountable for the soft and safe landing on the moon. It also looks like a box-shaped structure, which contains 4 landing thrusters and 4 lending legs of approximately 800 newtons respectively. It will bring the rover and numerous types of scientific instruments to operate on-site investigation and examination. The lander of Chandryan-3 is well-equipped and furnished with a Laser Doppler velocimeter (LDV). The effect legs are created more powerfully as compared to Chandryaan-2 which augmented the instrumentation redundancy. ISRO is continuously working on structural rigidity improvements along with the accumulation of several contingency systems.

Rover: This contains the Overview of the Chadryan-3 Rover which includes:

  • Approximately 26kg of weight (57 pounds)
  • Six-wheeled design
  • 500 meters of Range (1,640 feet)
  • Numerous kinds of scientific instruments such as spectrometers, cameras, and drill as well.
  • Anticipated lifespan of one Celestial Day (Nearly 14 days of Earth)
  • Overall communication with the lander and ground regulator team of India.

The Rover of Chandryaan-3 is probably to make various crucial scientific discoveries, such as:

  • The occurrence of water ice in the soil of lunar
  • The background of lunar impacts
  • The development of the lunar atmosphere.

Indian Space Research Organization (ISRO) demanded the initial funding of the overall project of approximately Rs. 75 corers (US 9.4 million $), out of which the amount of 60 crore (US 7.5 million $), will be for assembling expenses towards different types of equipment, machinery, and extra capital expenses, though the outstanding 15 crores (US 1.9 million $), is coming under the head of revenue expenditure, In December 2019. After confirmation of the existing project, the former chairman K. Sivan of the Indian Space Research Organization (ISRO) stated that the assessed and predictable cost would be nearly Rs. 615 crores which are corresponding to approximately 721 crores (US 90 million $), in 2023 mission of Chandryan-3.
