Successful Launch on 14:43 IST on Monday 22 July 2019

Second Attempt: Monday 22 July 10:13 BST (14:43 IST)
First Attempt: Sunday 14 July – 22:21 BST. ** Launch aborted at T- 56M 24s**

Reason for abort: The third stage of the GSLV Mk3 uses a cryogenic engine where liquid Hydrogen and liquid Oxygen are the propellents. Loading these propellents (first Oxygen and then Hydrogen) is completed just minutes prior to lift off.  A Helium container above the Oxygen tank began to leak at a particular pressure. It was the detection of this leak at T-56 minutes that the mission was aborted. ISRO engineers have confirmed that they can make the fix at the launch pad without the need to return the launch vehicle to the Vehicle Assembly Building.

Reschedule: The new launch date is 22nd July 2019 at 10:13 BST. Chandrayaan-2 was going to take 54 days to get to the Moon, the delayed departure will be compensated for during the Earthbound manoeuvres. It will now take 47 days to get to the Moon. The original landing date of 6th September will not change.

If all goes to plan (weather is looking a little dodgy) Chandrayaan-2, India’s second moon mission will lift off from India’s Space Port – Sriharikota at 22:21 BST. This will be India’s second Moon mission since Chandrayaan-1 launched in 2008. 

This mission consists of an orbiter, lander and a rover. It will be launched on a GSLV Mk3, India’s “heavy lift” launcher. To date, the GSLV-Mk3 has had 3 successful flights (one of which was suborbital). Click on any image to open gallery view.
