New Delhi, July 22, 2019 : After successful launch of Chandrayaan2 by ISRO, Prime Minister Narendra Modi tweeted photos of him watching Live telecast.
PM Modi tweeted, “Special moments that will be etched in the annals of our glorious history! The launch of Chandrayaan 2 illustrates the prowess of our scientists and the determination of 130 crore Indians to scale new frontiers of science. Every Indian is immensely proud today!
Indian at heart, Indian in spirit! What would make every Indian overjoyed is the fact that Chandrayaan 2 is a fully indigenous mission. It will have an Orbiter for remote sensing the Moon and also a Lander-Rover module for analysis of lunar surface.
Chandrayaan 2 is unique because it will explore and perform studies on the south pole region of lunar terrain which is not explored and sampled by any past mission. This mission will offer new knowledge about the Moon.
Efforts such as Chandrayaan 2 will further encourage our bright youngsters towards science, top quality research and innovation. Thanks to Chandrayaan, India’s Lunar Programme will get a substantial boost. Our existing knowledge of the Moon will be significantly enhanced.”
India’s Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1 successfully launched Chandrayaan-2 spacecraft at 2:43 p.m. IST on July 22,2019 into its planned orbit with a perigee (nearest point to Earth) of 169.7 km and an apogee (farthest point to Earth) of 45475 Km. The launch took place from the Second Launch Pad at Satish Dhawan Space Centre SHAR, Sriharikota.
After the injection of Chandrayaan-2 spacecraft, a series of maneuvers will be carried out using its onboard propulsion system to raise its orbit and place it in the Lunar Transfer Trajectory.
On entering Moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. Subsequently the orbit of Chandrayaan-2 around the moon will be circularised to a 100×100 km orbit through a series of orbital maneuvers.
On the day of landing, the Lander (Vikram) will separate from the Orbiter and then will 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. Vikram will attempt to make a soft landing in a high plain between two craters — Manzinus C and Simpelius N — at a latitude of about 70° South on 7th September 2019.
Subsequently, the Rover (Pragyan) will roll out and carry out experiments on Lunar surface for a period of 1 lunar day which is equal to 14 Earth days. The mission life of Vikram is also 1 lunar day. The Orbiter will continue its mission for a duration of one year.
