Sriharikota, July 23: The Indian Space Research Organisation (ISRO) successfully launched India's second moon mission Chandrayaan 2 on Monday at 2:43 pm. In this lunar mission, the heavy-lift rocket GSLV-MkIII, nicknamed 'Baahubali', carried Chandrayaan 2 to the Earth's orbit, from where it will travel to the moon. The Chandrayaan 2 spacecraft will land a rover near the unexplored lunar southern pole. The Rs 978 crore Chandrayaan-2 project will take 48 days to complete the task of landing on the Moon. Do you know where is Chandrayaan 2 now after yesterday's launch and how and when it will reach the Moon? Here's a complete explanation of the path of India's second moon mission.

It is one of the most prestigious missions ever undertaken by ISRO since its inception. Chandrayaan 2 will make India the fifth country to soft-land on the lunar surface after Russia, the United States, Japan and China. The spacecraft used in the mission has three distinct parts: an orbiter, a lander and a rover. The orbiter weighs 2,379kg (5,244lb) will take images of the lunar surface. Chandrayaan 2 Explained! When Will ISRO's GSLV-Mk III Reach Moon And What Will Happen After That?
Here is a detailed look at the path which Chandrayaan 2 will take to reach the Moon during its 48-day tour.
- About 16-minutes into its flight, the Rs 375-crore GSLV-Mk III rocket slung the Rs 603-crore Chandrayaan-2 into its 170x39,120-km orbit.
- For the first 17 days from its liftoff and till Day 23, the spacecraft will be in Earth-bound phase before its orbit is finally raised to over 1.05 lakh km.
- From Day 23-30, it will nudge into the Lunar Transfer Trajectory, thus taking it to the proximity of the moon
- On Day 43, it will be brought to 100 X 100 km circular orbit when the lander will separate.
- Over the next few days of orbiting, the decent will start and it is expected to make a soft landing on the Moon on Day 48.
According to a BBC report, in order to save fuel, ISRO has chosen a circuitous route to take advantage of the Earth's gravity, which will help slingshot the satellite towards the Moon. India does not have a rocket powerful enough to hurl Chandrayaan-2 on a direct path.

ISRO has sent up three GSLV-Mk III rockets so far. The first carried Crew Module Atmospheric Re-entry Experiment in December 2014. The second and third GSLV-Mk III carried communication satellites GSAT-19 and GSAT-29 in February 2017 and November 2018 respectively. GSLV-Mk III will also be used for India's manned space mission in 2022.
The Mission was aborted on July 15 by ISRO due to a technical snag that was identified an hour before its launch. However, the glitch was soon fixed and Chandrayaan 2 was successfully launched on July 22, with ISRO stating that the lift-off was "better than they had expected". If Chandrayaan 2 finds water on the south pole, which is the dark side of Moon, it will be a huge achievement and a moment of great pride for ISRO scientists who've worked day and night on the mission.
