NEW DELHI: The Chandrayaan-3 mission is scheduled to be launched at 2.35pm on July 14 from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.
The lander of Chandrayaan-3 is expected to soft-land on the surface of the Moon on August 23 or 24.
Where and how to watch
On Friday, the Indian Space Research Organisation (Isro) invited citizens "to witness the launch from the the Launch View Gallery at SDSC-SHAR, Sriharikota, by registering at https://lvg.shar.gov.in/VSCREGISTRATIO.
Documents you will need:
Aadhar card / driving license / any govt issued ID, mobile number & email ID for hassle free and quick registration process.As part of Covid-19 precautions, visitors are requested to produce either vaccination certificate (2 doses) or Covid-19 negative certificate. Visitors are requested to ensure compliance to the above and produce proof either hard copy or digital/soft copy on demand.
The launch view gallery was inaugurated in 2019 and is part of the under-construction Space Theme Park, which includes a Rocket Garden and a Space Museum.
The museum is open to the public and provides an in-depth account of the Indian space programme from its infancy. The story of the Indian space programme is unfurled in six sections, comprising of history, education, technology, applications, global and the future.
Watch online
Citizens can also view the historic launch online at Isro's official YouTube channel: https://www.youtube.com/@isroofficial5866
A live link will also be active at Isro's official website on the launch date: https://www.isro.gov.in/
'Science from/of the moon'
The Chandrayaan-3 mission carries scientific instruments to study the thermo-physical properties of the lunar surface, lunar seismic activity, lunar environment and elemental composition in the vicinity of the landing site.
The mission objectives of Chandrayaan-3 are:
To demonstrate Safe and Soft Landing on Lunar SurfaceTo demonstrate Rover roving on the moon andTo conduct in-situ scientific experiments
While the scope of the scientific instruments on the lander and the rover would fit in the theme of 'Science of the Moon', another experimental instrument will study the spectro-polarimetric signatures of the Earth from the lunar orbit, which would fit in the theme of 'Science from the Moon', said Isro officials.

2/8:Landing will be on August 23 or 24
<p>Landing will be on August 23 or 24 as we want the landing to happen on the first lunar day so we get 15 days to work, Isro chairman S Somanath said.<br /><br /><br /><br /><br /></p>ANI
3/8:Chandrayaan-3 is a composite of three modules
<p>While Chandrayaan-3 is a follow-on mission to Chandrayaan-2, unlike its predecessor, which carried an orbiter along with a lander and rover, this spacecraft is a composite of three modules: Propulsion, lander and rover.<br /><br /><br /></p>ANI
4/8:Vikram will have stronger legs than in its previous avatar
<p>This time around, Vikram will have stronger legs than in its previous avatar to enable withstanding landing at greater velocities than earlier, while Isro has also made several other changes learning from the failures of Chandrayaan-2.<br /><br /><br /></p>ANI
5/8:Isro has carried out several changes on the lander
<p>After its failed landing attempt in September 2019, Isro has carried out several changes on the lander for Chandrayaan-3.<br /><br /><br /><br /></p>ANI
6/8:Lander legs, whose velocity tolerance has been enhanced to 3m/second
<p>One is the lander legs, whose velocity tolerance has been enhanced to 3m/second from 2m/second. That means even at 3m/sec, the lander will not crash or break its legs.<br /><br /><br /></p>ANI
7/8:More cushion to handle the mission
<p><br /><br />Isro has also added more fuel to handle more disruptions and have the “ability to come back” so there’s more cushion to handle the mission.<br /><br /><br /><br /><br /></p>ANI
8/8:Isro has also improved the software
<p>Isro has also improved the software to have more tolerance to failures like engine disruptions, thrust disruptions, sensor failures, etc, while also removing the central or fifth engine, which was added last minute during Chandrayaan-2<br /><br /><br /></p>BCCLIn March this year, the Chandrayaan-3 spacecraft successfully completed the essential tests that validated its capability to withstand the harsh vibration and acoustic environment that the spacecraft would encounter during its launch.
The Chandrayaan-3 module was recently integrated with the Launch Vehicle Mark-III (LVM3) and the agency on Friday tweeted that all the electrical tests of LVM3-M4/Chandrayaan-3 had been completed.
