India’s Second Lunar Mission Chandrayaan-2 Successfully Launched

India’s Geosynchronous Satellite Launch Vehicle GSLV MkIII-M1, successfully launched the 3840 kg Chandrayaan-2 spacecraft into an earth orbit today (22/07/2019). Chandrayaan-2 is India's second mission to the moon. It comprises a fully indigenous Orbiter, Lander (Vikram) and Rover (Pragyan). The Rover Pragyan is housed inside Vikram lander.

GSLV Mk III is a three-stage launch vehicle developed by Indian Space Research Organisation (ISRO). The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage. The vehicle is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO).

The mission objective of Chandrayaan-2 is to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface. On the science front, this mission aims to further expand our knowledge about the Moon through a detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere leading to a better understanding of the origin and evolution of the Moon.

The Lander will soft land in the South polar region of the Moon on September 7, 2019. Following this, the Rover will roll out from the lander and carry out experiments on the lunar surface for a period of 1 lunar day (equal to 14 Earth days). The mission life of the lander is also 1 lunar day. The Orbiter will continue its mission for a duration of one year.

Chandrayaan-2 has several science payloads to facilitate a more detailed understanding of the origin and evolution of the Moon. The Orbiter carries eight payloads, the lander carries three, and the rover carries two. Besides, a passive experiment is included on the lander. The Orbiter payloads will conduct remote-sensing observations from a 100 km orbit while the Lander and Rover payloads will perform in-situ measurements near the landing site.

 

Prime Minister of India Shri Narendra Modi’s message on launch of Chandrayaan 2:

 “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.”
