Chandrayaan 3: the final countdown has begun to launch today, July 14, at 2:35 PM (IST)

Chandrayaan 3: The final countdown has begun. The long wait is finally coming to an end as it was resheduled after the announcement to launch on 13 July, 2023. Only a few hours are left today. After that, ISRO will launch the third Chandrayaan, i.e. Chandrayaan 3. India is going to the moon for the third time. The whole country is witnessing another historic moment.

As always, there is excitement. Today, July 14, 2023 at 2:35 PM India time, the Indian Space Research Organization (ISRO) is going to launch the lunar probe. The spacecraft will take off from the launch pad of the Satish Dhawan Space Center in Sriharikota. It will be the fourth country to make new history. Next 23 On August 24, Chandrayaan 3 - Lander and Rover are said to touch the ground. The truth is that this is the history of India. For, Chandrayaan 3 is going to be the first spacecraft that will touch the soil of the South Pole of the Moon.

Chandrayaan-3 has already been launched along with launch vehicle Mark-3 at the Satish Dhawan Space Research Center in Andhra Pradesh.

👉 Initial construction of Chandrayaan-3

Chandrayaan-3-It has a lander, a rover and a propulsion module. The total weight of Chandrayaan-3 is 3 thousand 900 kilograms. The weight of the propulsion module is 2 thousand 148 kilograms. The goal of this propulsion module is to reach the lander and the rover up to 100 kilometers of the lunar orbit. The rover inside the former weighs 1,752 kilograms. The total weight of the rover is 26 kilograms.

Chandrayaan-2 rover 'Vikram' has the characteristics of rover used as Chandrayaan-3. However, the rover has been technologically improved for the rover to touch the lunar soil smoothly. will produce

👉 Chandrayaan-3's main objective

According to ISRO's website, the main goal is to land Chandrayaan-3 on the lunar surface without any mechanical problems. Chandrayaan-3 will soft land on the dark side of the South Pole without any mechanical problems. ISRO wants to start a new chapter of lunar exploration through advanced technology. Another important objective of the Chandrayaan-3 mission is to search for unknown information.

👉 Chandrayaan 3 - What is the lander, rover and propulsion module?

Chandrayaan 3 is designed in such a way that soft land core rover is placed on lunar surface.

The propulsion module will help the lander to reach the final lunar orbit of 100 km. After entering the lunar orbit, the lander and the propulsion module will separate from each other. The propulsion module will separate from the lander and rotate in the lunar orbit. The satellite will serve as the propulsion module.

Incidentally, commands are sent from Earth's space station through communications relay satellites. Such commands are then relayed to satellites used for reconnaissance.

The lander, rover and propulsion modules will carry their own science payloads. According to NASA, the propulsion module looks like a box. One side of the top is a large solar panel. Attached to the other side is a large cylinder. The cylinder is called the Intermodule Adapter Cone. It essentially acts as the lander's roof. A. The thruster angel is located below the propulsion module. The box-shaped lander has four landing legs, four landing thrusters, several sensors for a smooth landing on the lunar surface, and a camera to determine the exact location of the lander to detect hazards in advance. The lander also has an X-band antenna. This antenna will be added.

On the other hand, the rover is rectangular in shape. The rover has 6 wheels and a navigation camera.

👉 Chandrayaan-3- payloads

The Chandrayaan-3 lander has five payloads. The five payloads are Chandra's Surface Thermophysical Experiment (ChasTE), Instrument for Lunar Seismic Activity (ILSA), Langmuir Probe, Laser Retroreflector Array (LRA) Rover, and Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA).

ChasTE will examine the temperature of elements in the south polar region of the Moon. ILSA will measure surface vibration around the landing site. LP will estimate plasma density, helping to understand the dynamics of the Moon on NASA's LRLRA spacecraft.

The rover has two payloads, the Alpha Particle X-Respectrometer (APXS), and the Laser Induced Breakdown Spectroscope (LIBS). APXS will determine the initial composition of lunar soil and rocks around the landing site. LIBS will work to estimate the chemical and mineral composition of the lunar surface. The lander will have a vertical velocity of about 2 meters per second when it touches the lunar surface, while the horizontal velocity will be about 0.5 meters per second. It is about 120 degrees.
