Chandrayaan-3 To Land On Lunar Surface On Aug 23: ISRO

ISRO’s much-awaited mission Chandrayaan-3 will land on the lunar surface on Wednesday, 23rd August.

 ISRO said that the mission will make a soft landing on the moon at 6:04 pm. 

Earlier, the Chandrayaan-3 mission had successfully completed the final deboosting phase today itself, after which the distance of Chandrayaan-3 from the lunar surface has been reduced to just 25 km. ISRO gave this information by tweeting.

ISRO said that now the lander module will be internally checked and now just waiting for the sun to rise on the fixed site of landing on the moon. 

ISRO said that the lander module could land on the lunar surface on August 23, 2023 at around 5.45 pm. However, now a new time has been issued for its landing.

Chandrayaan-3 mission is the next phase of Chandrayaan-2, which will land on the lunar surface and conduct tests. 

It consists of a propulsion module, a lander and a rover. Chandrayaan-3’s focus is on a safe landing on the lunar surface. 

New equipment has been created for the success of the mission. The algorithms have been improved. The reasons for which the Chandrayaan-2 mission could not land on the lunar surface have been focused on. 

Chandrayaan-3 took off from the Sriharikota Center on July 14 at 2:35 pm and if all goes according to plan, it will land on the lunar surface on August 23. 

The mission is being sent to that part of the Moon, which is called the Dark Side of the Moon. This is because this part does not come in front of the earth.

There was great news on Thursday (17 August) for India’s Chandrayaan-3 mission. According to the plan, the lander and propulsion module of Chandrayaan-3 are traveling to the moon separately by dividing into two pieces. 

ISRO tweeted that the propulsion module can continue its journey in the current orbit for months or years. 

The propulsion module carries the Spectro-Polarimeter of Habitable Planet Earth (SHAPE) payload to conduct spectroscopic studies of the Earth’s atmosphere and measure the variation in polarization from clouds on Earth. This will give us information about whether the Moon is habitable or not.

M Annadurai, who was the project director of Chandrayaan-1, says that the separation of the lander module is a big opportunity. Now we will know how the lander is doing. 

The lander will now be certified and tested, after which it is slowly being brought closer to the moon. 

It will then be given the necessary instructions, so that it takes the signal to move to the target location and make a safe landing on August 23.

Lander module of Chandrayaan-3 has made important changes for soft landing this time. It has reinforced legs to deal with any unexpected impact. It also gets more equipment, updated software and a bigger fuel tank. These tools will be vital in case any last minute changes have to be made. 

The Chandrayaan-3 mission consists of a lander, a rover and a propulsion module. The lander and rover will land on the south pole of the moon and conduct experiments for 14 days. Whereas the propulsion module will study the radiations coming from the lunar surface by staying in the lunar orbit. 

Through this mission, ISRO will detect water on the lunar surface and will also know how earthquakes occur on the lunar surface. 

Former ISRO scientist Annadurai says, “The south pole region of the moon is also being explored because there may be a possibility of presence of water in the permanently shadowed regions around it.”
