New Delhi:

India's second lunar mission Chandrayaan-2, launched on July 22, will attempt a touchdown on unchartered lunar south pole between 1:30 am and 2:30 am on Saturday. Dubbed as the most complex and prestigious mission ever undertaken by the Indian Space Research Organisation (ISRO), Chandrayaan-2 has three elements including the Rover, the Lander and the Orbiter. Prime Minister Narendra Modi along with 60 students from across India will be at the ISRO Centre in Bengaluru to witness the "extraordinary moment in the history of India's space programme". Meanwhile, ISRO is aiming for a soft landing of lander 'Vikram' in the South Pole region of the Moon where no country has gone so far. If successful, the Rs 978 crore mission will make India the fourth country after Russia, the US and China to pull off a soft landing on the Moon.

Here are the LIVE updates:

"We are proud of our scientists. They have created history. No need to lose heart. Our scientists have done a great job," said Arvind Kejriwal

We are 26 minutes away from initiating the process of landing, says ISRO.

According to ISRO, 'Pragyan' can only communicate with the lander, while 'Vikram' has the capability to communicate with IDSN (Indian Deep Space Network) at Byalalu near Bengaluru, as well as with the orbiter and rover.

The mission objective is to locate presence of water and other important minerals on the lunar surface.

Vikram's mission period is of 14 earth days during which time, various tests will be conducted. 

Hours after the touchdown, Vikrams door will open creating a slope for the matchbox shaped rover with six-wheels to slide and move around the lunar surface to carry out various investigations. 

Two navigation cameras, which could be called as its left and right eye, are mounted on top of it besides an Alpha particle X-ray spectrometer, receive and transmit antenna and rocker bogie assembly.

The cubical vehicle, exclusively designed for travelling on the moon, is fitted with a solar panel. 

The touchdown of ‘Vikram’ is scheduled between 1.30 am and 2.30 am.

Chandrayaan-2's payloads consists of Terrain Mapping Camera-2, Large Area Soft X-ray Spectrometer, Solar X-Ray Monitor, Imaging IR Spectrometer among others.


Pragyan - Chandrayaan-2's rover is a 6-wheeled robotic vehicle, which translates to 'wisdom' in Sanskrit. It can travel up to 500 m (0.5 km) at a speed of 1 cm per second and leverages solar energy for its functioning.


'Vikram' - Chandrayaan-2's lander, is named after Dr Vikram A Sarabhai, the Father of the Indian Space Programme. It is designed to function for one lunar day, which is equivalent to about 14 Earth days.


At the time of launch, Chandrayaan-2 Orbiter will be capable of communicating with Indian Deep Space Network at Byalalu, as well as with Vikram lander.


Chandrayaan-2 will be aided in achieving its mission by some of India’s most advanced engineering marvels. Its composite module, comprising technology and software developed across India, includes a wholly indigenous rover and India's 1st lander capable of executing a 'soft landing'.


Hours before Chandrayaan-2 landing on Moon, Prime Minister Narendra Modi arrives at Bengaluru Airport. He will reach ISRO centre in the state.



The GSLV Mk-III will carry Chandrayaan-2 to its designated orbit. This three-stage vehicle is India’s most powerful launcher to date, and is capable of launching 4-tonne class of satellites to the Geosynchronous Transfer Orbit (GTO).


Here are the details of flight sequence of Chandrayaan-2.


The second earthbound orbit-raising manoeuvre for Chandryaan-2 spacecraft performed on July 26 while the third one took place on July 28.
