Chandrayaan-3, India’s third lunar mission, is in its last 90 minutes of preparation. In the cryogenic engine that will launch the rocket on its third and final stage, liquid oxygen has been filled to the max.
The liquid hydrogen charge of the cryogenic engine is also almost complete. The liquid second stage of the LVM 3 rocket has been filled with propellant. After the initial power increase of the two solid booster engines ignited at takeoff at 14:35:17, the liquid second stage will ignite.
The goal of the mission is to do what its predecessor could not: land softly on the surface of the moon and send a robot to explore it. If India does make a soft landing, it will be the fourth country to do so, after the United States, Russia and China. After being launched into an orbit around Earth at an altitude of 179 km on Friday, the spacecraft will gradually increase its orbit through a series of maneuvers to move away from Earth’s gravity and hurtle toward the Moon. When the spacecraft approaches the moon, it will need to be pulled by the moon’s gravity. Once that happens, the lander, which is supporting the rover, will detach from the propulsion section and begin its powered descent.
Top 10 updates on this great story
- India’s first lunar mission, Chandrayaan-1, was launched in October 2008 and operated until August 2009.
- The Chandrayaan-2 lander experienced a hard landing in 2019 after veering off the intended trajectory. While still orbiting the moon, the orbiter is transmitting data.
- The new mission, according to Mr. Somanath, has been created to land successfully even if some components malfunction. Various situations, such as sensor failures, motor failures, algorithm failures, and calculation failures, were investigated and solutions were devised.
- Following the lessons of the previous lunar mission, ISRO claims to have updated the software and reduced the number of engines on the lander from five to four. Everything has been extensively tested.
- The researchers want to examine lunar soil, explore the moon’s surface, and record moonquakes.
- Vikram is supposed to land smoothly and safely. Subsequently, the lander will launch the Pragyan rover, which will conduct research and explore the moon’s surface for one lunar day (14 days on Earth).
- India’s lunar spacecraft will make history when it lands on the moon’s South Pole, where water molecules have been discovered. The discovery, which was made during India’s maiden lunar mission in 2008, shocked the world.
- “There were out-of-nominal events that were initiated in the system, which was the fundamental failure on the most recent Chandrayaan-2 mission. Not everything was what it seemed. And the vehicle was unable to handle the atypical conditions for a safe landing, according to ISRO chief S Somnath in an exclusive interview with NDTV.
- After its most recent lunar mission in July 2019 failed, the Indian Space Research Organization is crossing its fingers.
- The Bahubali rocket, also known as the GSLV Mark 3 Heavy Lift Launch Vehicle, will support the Vikram lunar lander. The LM-3, which is what the GSLV is now called, is 43.5 meters high, which is about half the height of the Qutb Minar in Delhi. After a journey that will last more than 40 days, the spacecraft will land on the moon on August 23.
