What Is Chandrayan –3?

Chandrayaan-3 is the third and most recent lunar Indian Space Research exploration mission under the Chandrayaan programme of ISRO.  Chandrayaan-3 was launched on 14 July 2023, at 2:35 pm IST as scheduled, from Satish Dhawan Space Centre It consists of a lander named Vikram and a rover named Pragyan similar to Chandrayaan-2. Chandrayaan-3 is set to land on the Moon on August 23, 2023, around 18:04 Hrs. IST.

What’s So Special About Chandrayaan – 3?

As we prepare to uncover new knowledge, Chandrayaan 3 brings the hope of learning more about what the Moon’s south pole that has never been explored before, and how it might help us understand the universe. With careful planning, creative technology, and strong dedication, this mission is set to tackle the difficulties of exploring the Moon and set the stage for humans to one day explore beyond our planet.

What Is Chandrayaan-3's Goal?

Achieved a successful soft landing on the Moon’s surface

  • Study the Moon’s composition to understand its elements and minerals.
  • Explore the Moon’s history by analysing its geological features and craters.
  • Deploy a rover to conduct experiments and gather data on the lunar environment.
  • Advance technology through innovative engineering for lunar exploration.
  • Encourage international collaboration in space research and exploration.
  • Contribute to humanity’s broader understanding of the Moon and space.

What is the Purpose of Launching Chandrayaan-3?

The main Purpose of Chandrayaan 3 is to explore the Moon better than before. It wants to land gently on the Moon and study its surface in detail.

This mission learns from Chandrayaan 2’s experiences and aims to do an even better job at understanding the Moon.The Chandrayaan-3 is aimed at the lunar south pole, a region with water ice, or frozen water, that could be a source of oxygen, fuel and water for future moon missions or a more permanent moon colony.

Candrayaan – 3 Successful Landing Live Updates

Chandrayaan-3 is set to land on the Moon on August 23, 2023, around 18:04 Hrs. IST.

Chandrayaan-3 Moon Landing: ‘We are extremely confident that it is going to be a successful mission,’ says ISRO chief S. Somanath. Chandrayaan-3 LIVE updates: In an exclusive interview with Hindustan Times, ISRO Chief S Somnath expressed his confidence that it is going to be a successful mission.

We have complete faith that Chandrayaan-3’s gentle landing will be successful. The ‘Vikram’ lander part of the spacecraft was successfully separated from the propulsion module on Thursday. After that, it went through important manoeuvres to lower its orbit slightly in preparation for landing 

 

Now That The Launch Is Successful, What Will Chandrayaan-3 Do On The Moon?

After Successful landing, Vikram Lander will touch the lunar surface. The landing sensors will signal the onboard computer to awaken the systems. The Lander will power up fully, and the ramp for the rover named Pragyan will unfold. Pragyan, like a little explorer, will roll out onto the lunar ground.

What Is The Difference Between Chandrayaan-3 And Chandrayaan-2?

Chandrayaan 2 lander had five thrusters and a limited capability to land at a 500×500 square meter area. It used pictures taken to assess landing.

Chandrayaan 3 lander has four thrusters and stronger legs. It has the capability to land at 4km x 2.5 km. It will use data generated by Chandrayaan 2 orbiter to land successfully. Furthermore, it has additional solar panels to generate power after landing. 

Chandrayaan-3 VS Chandrayaan-2

Chandrayaan-2

The soft landing of Chandrayaan-2 was planned to be carried out in multiple phases. Certain unexpected variations in the performances of the Lander Module eventually resulted in higher velocities at touchdown, which was beyond the designed capability of the Lander’s legs, resulting in a hard landing.
