With the Chandrayaan 2 launch, India's historic Moon mission has taken off
Chandrayaan 2, India's second mission to the Moon, just launched from the Satish Dhawan Space Centre in Sriharikota in India.
- The satellite has successfully separated from the launch vehicle is in the geostationary transfer orbit.
- Chandrayaan 2 is expected to reach the Moon in Septermber after a 48 day journey through space.
“The satellite has successfully separated from the launch vehicle,” K. Sivan, ISRO chairman, told the press after Chandrayaan successfully separated from its launch vehicle, the ‘Bahubali’ GSLV Mark III.
In fact, the launch went better than expected with GSLV Mark III launching Chandrayaan 2 6000kms further than expected giving the the satellite more fuel and life for its maneuvers later in the journey.
My dear friends, today is a historical day for space, science and technology in India. I’m extremely happy to announce that GSLV Mark III successfully injected Chandrayaan 2 in the defined orbit. Infact, orbit is 6000kms more than what we expected.
India may be the fourth nation after the United States, Russia and China to land on the Moon but it will be the first one to ever land on the natural satellite’s South Pole. This is also India’s 73rd launch mission from SDSC.
Take-off after tweaked countdown
The 24-hour countdown began a little later than scheduled at 6:43 on Sunday evening because ISRO was reportedly superstitious about avoiding Rahu Kalaam.
Chandrayaan 2 received authorisation of the launch from the mission director 18 minutes ahead of the launch following which the vehicle director and cryo chief will authorised the vehicle operations sequence.
During the launch's initial stage, the S200 burners are ignited on ground. Following which the L1 10 rocket was ignited, one of the primary engines of the GSLV Mark III vehicle.
The S200's subsequently separated after which the launch was under close loop guidance which was followed by the vehicle's shedding its heat shields.
The cryogenic stage then ignited and performance was reported as normal at 204 kms around 405 minutes into the launch.
The crygenic stage burnt out after 8 more minutes and the satellite successfully separated from the launch vehicle to enter geostationary transfer orbit (GTO).
The Chandrayaan 2 will undergo 15 crucial maneuvers before actually landing on the Moon’s South Pole.
Chandrayaan 2’s journey through space
Chandrayaan 2 is going to attempt a soft landing on the Moon’s South Pole — one of the most cratered lunar surfaces. K. Sivan, the ISRO chairman, has dubbed the 15 minutes of that land to be the ‘most terrifying’ that the team will face during the mission.

ISRO Chief K Sivan says Chandrayaan 2 "bounced back with flying colours" but that task is not over yet
