The much-anticipated launch of Chandrayaan 3 mission by the Indian Space Research Organisation (ISRO) is scheduled for two.35 pm IST on July 14 from the Satish Dhawan Space Centre, Sriharikota.
The lunar mission is a follow-up to the Chandrayaan 2, launched in September 2019 and which didn’t full the gentle touchdown because of a issues with the onboard laptop and the propulsion system, and crashed on the moon’s floor.
The Chandrayaan 3 mission plans to display end-to-end functionality in protected touchdown and roving on the lunar floor. It will forego the orbiter from the earlier mission,

The mission’s primary aims are:
- To display protected and gentle touchdown on the lunar floor
- To display rover roving on the moon and
- To conduct in-situ scientific experiments.
First introduced in January 2020, ISRO started the event part of Chandrayaan 3, with scientists and engineers engaged on the design and meeting of the spacecraft. The lander for the present mission has extra strong affect legs than Chandrayaan 2.
Initially slated to be launched in early 2021, the event and assembling of the spacecraft was delayed due by the COVID-19 pandemic. The second wave of the pandemic brought about additional delays though the manufacturing and testing of the propulsion methods had been nearly completed by May 2021.
With the date lastly being set on July 2023, the spacecraft will be launched onboard the Launch Vehicle Mark 3 (LVM 3) rocket.

Consisting of a separate lander and rover module, the spacecraft is prone to land close to the moon’s South Pole and function for one lunar day, equal to 14 earth days.
The present mission will observe the identical trajectory as Chandrayaan 2, the place the propulsion module will orbit earth a number of occasions earlier than slingshotting in direction of the moon. Once throughout the moon’s gravitational pull, the module will decrease itself to a 100 x 100 km round orbit. Then, the lander will detach and descending to the floor.
The module will take roughly a month to achieve the moon from the time of launch. The touchdown is scheduled for August 23-24, though this will likely change relying on when the Sun rises over the Moon. If there’s a delay, ISRO will reschedule the touchdown for September.
The earlier ISRO chairperson Okay. Sivan has described the descent as “15 minutes of terror”.
Once on the lunar floor, the lander, known as ‘Vikram’ (after Vikram Sarabhai), will deploy its 4 scientific payloads to review the moon’s floor temperature and subterranean traits. The module has an instrument known as the ‘Spectro-polarimetry of HAbitable Planet Earth’ (SHAPE), which will acquire knowledge in regards to the gentle emitted and mirrored by the earth.
The rover, known as ‘Pragyan’, will research the lunar floor utilizing chemical checks as it roves round.
