Chandrayaan 2: Ascending towards the launch pad

Leveraging nearly a decade of scientific research and engineering development, India’s second lunar expedition will shed light on a completely unexplored section of the Moon — its South Polar region. This mission will help us gain a better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface.

Journalist Pallava Bagla shared an image on June 18th, confirming the departure of the satellite from its bangluru centre and is headed towards Satish Dhawan Space Centre (SDSC) SHAR spaceport in Sriharikota, Andhra Pradesh, where the launch is scheduled. Chandrayaan-2 is expected to make a soft landing in the south polar region of the Moon on September 6. ISRO calls the landing “15 terrifying minutes”.

Set to launch on July 15th, Chandrayaan 2 is on a mission unlike before. Chandrayaan-2 will be launched from Satish Dhawan Space Center at Sriharikota on-board GSLV Mk-III. The earth parking will be of 170 x 40400 km orbit with a series of maneuvers carried out to raise its orbit and change the course of Chandrayaan-2 to Lunar Transfer Trajectory. On entering Moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. On the day of landing, the lander will separate from the Orbiter and then perform a series of complex maneuvers comprising of rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones. The lander-Vikram will finally land near South Pole of the moon on 6th September 2019. Subsequently, Rover will roll out and carry out experiments on Lunar surface for a period of 1 Lunar day which is equal to 14 Earth days. Orbiter will continue its mission for a duration of one year.
