With chandrayaan-2 ISRO is going to all new level

Chandrayaana-2 the most anticipated project of ISRO (Indian Space Research Organization) will put India among the leader of space research. On 15^th of July the Geosynchronous Satellite Launch Vehicle Mark III (GSLV MkIII) will start the journey towards moon which carries an Orbiter, a lander and a rover with launch mass of 3877 kg from Satish Dhawan Space centre. With this India will become 4th country ever to land on the lunar surface.

Purpose of Chandrayaana-2:

ISRO has specifically chosen Lunar South pole where more surface area remains in shadow while compared to the North pole. In Chandrayaana-1 water molecules were discovered and the ISRO is eager to study the water molecule distribution on the lunar surface so they have chosen lunar surface which is permanently shadowed. Also ISRO is doing topographical studies to understand the origin and evolution of moon. Topography, composition, Search for water and In-situ studies are main area of focus for Chandrayaana-2.

Parts GSLV MkIII is taking in it:

1. Orbiter: On reaching the moon surface the orbiter will release the lander and will be kept on 100X100 km lunar orbit which is capable of communicating between Indian Deep Space network(ISDN) and lander. The life span of this Orbiter is one year.
2. Lander: Vikram Lander. As the name itself suggests Lander will be responsible for soft landing of Rover on lunar surface. This lander is will function for about one lunar day which is quivalne to 14 days on earth. The lander is named after Dr. Vikram Sarabhai who is regarded as the father of Indian Space programme. Vikram will communicate with ISDN as well as Orbiter and Rover.
3. Rover : Pragyan rover. Rover is basically a vehicle which moves on the lunar surface at speed of 1 cm per second. While the 6-wheeled robotic vehicle is moving on the surface of moon it will perform On-site chemical analysis. The rover can move up to 500 m. It will communicate with Vikram, the Lander.

Chandrayaana-2: the flow

On 16^th july 2019 the GSLV Mk-III will be launched from Satish Dhawan Space Center at Sriharikota. It will be injected into Earth Parking Orbit at 170 X40400 km. After that the Chandrayaana-2 will be put to lunar Transfer Trajectory through series of maneuvers. Once it reaches moon’s sphere, the orbit of the Chandrayaana will be circularized to 100X100 km. At last the lander will separate from orbiter which performs complex maneuvers at land on lunar surface. The landing of lander-Vikram is estimated to happen on 6th September 2019.
