Space exploration

                ISRO's most recent lunar Indian Space Research exploration mission under the Chandrayaan programme is Chandrayaan-3.Chandraayan-3 was launched on board LVM3-M4 rocket by ISRO from Satish Dhawan Space Centre on July 14.The aim of this mission is to measure the near - surface plasma density of the moon. Total weight of the rocket is 3900 kg as it consists of a propulsion module which weighs 2148 kg ,a lander and a rover module which weighs 1752 kg. The budget of the Chandrayaan 3 is 615 crores.

54 female engineers /scientists contribution to Chandrayaan 3.

The main objectives of ISRO's moon mission is:

  1. To demonstrate a safe and soft landing on lunar surface.
  2. To demonstrate rover roving on the moon.
  3. To conduct in- SITU scientific experiments

Technologies used in this mission:

1.Altimeters:

                Laser and RF based altimeters.

2.Velocimeters:

                Laser doppler velocimeter and lander ,Horizontal velocity camera.

3.Inertial Measurement:

                Laser Gyro based inertial referencing and accelerometer package.

4.Propulsion System:

          800N Throttleable Liquid Engines,58N attitude thrusters & Throtteable Engine Control Electronics.

5.Navigation, Guidance & Control (NGC);

                Powered Descent Trajectory design and associate software elements.

6.Hazard Detection & Avoidance:

                Lander Hazard & Avoidance camera and Processing Algorithm.

7.Landing Leg Mechanism 

Chandrayaan 3 includes lander and rover:




  • Rover:

                    Rover is named as Pragyan. Rover is like a cockroach which is equipped with wheels , which will crawl around the moon's surface and pick up the soil. It checks the thermal conductivity by placing its foot. 

  • Lander:

                        Lander is named as Vikram.It consists of 4 scientific instruments: seismometer for moonquakes, heat movement study on the lunar surface, exploration of  moon's plasma environment and a retro-reflector for gravitational interactions.

India's Historic Achievement:

                           India is the first country to land on the moon's south pole. After the United States, the Soviet union and China ,India is the fourth in successfully landing on the moon by Chandrayaan-3.

                           To attempt a soft landing on the moon Chandrayaan-3 takes nearly 45 days with long journey of 384,000 km.

                          Chandrayaan-3 was launched on 14th July 2023,at 2:35 pm IST as scheduled, from Satish Dhawan Space Centre second launch pad in Sriharikota, Andhra Pradesh, India. The spacecraft entered lunar orbit on 5 August 2023. Chandrayaan-3 landed gently on the moon around 6.04 pm on August 23,2023.
