| Video Discription | Chandrayaan 2 mission was launched on 22 July 2019 by ISRO India. Chandrayaan 2 spacecraft consists of a launcher GSLV Mark III M1, Orbiter, Vikram lander and Pragyaan rover. This was the first lunar mission which was going to the South polar region of the moon. In this video complete mission is explained in english. Launcher GSLV Mark III will carry Chandrayaan 2 spacecraft to its designated orbit. The orbiter will collect data while revolving around the moon in orbit of 100Km. Orbiter contains eight scientific instruments or payloads. Orbiter High-Resolution Camera will take landing site images prior to the separation of Vikram from the orbiter. The Vikram lander will soft-land on the moon's surface using its onboard computers. The rover Pragyaan can travel up to 500 meters and can communicate with only Vikram lander. But Vikram landing trajectory starts deviating from 2.1 Km above surface of the moon. Vikram lander crash was confirmed by ISRO chairman K Sivan. Both ISRO and NASA attempted to communicate with lander but unable to do. #chandrayaan2 Transcript: The Chandrayaan-2 The lunar South Polar Region where Chandrayaan-2 is going to land remains in shadow more than the north pole of the Moon. So there is a strong possibility of the presence of water. Let’s see from beginning how did ISRO developed the Chandrayaan-2 mission. In November 2007, Russian Federal Space Agency (ROSCOSMOS) and ISRO signed an agreement to work together on Chandrayaan-2 project. ISRO would have the prime responsibility for orbiter and rover while ROSCOSMOS was to produce the lander. On 18 September 2008, prime minister Manmohan Singh approved the mission in Union cabinet meeting. The design of spacecraft was completed in August 2009 with the scientists of both countries conducting a joint review. Although, ISRO finalized the payloads for Chandrayaan-2 per schedule. But the mission was postponed Because Russia was unable to develop the lander on time. Later ROSCOSMOS withdrew in wake of the failure of Fobos-Grunt mission to Mars. Since the technical aspect connected with Fobos-Grant mission were also used in the lunar project. When Russia cited its inability to provide the lander even by 2015. India decided to develop lunar mission independently. After a little time, Chandrayaan-2 was completed. The Chandrayaan-2 mission consists of a launcher GSLV Mark III, Orbiter, Vikram lander and the Pragyan Rover. All of which are developed in India. GSLV Mark III will carry Chandrayaan-2 to its designated orbit. The Orbiter. Weight over 2000 kgs It carries eight scientific instruments. That will collect data while revolving around the moon in orbit of 100 Km. The orbiter High-resolution camera (OHRC) will conduct the high-resolution observation of landing site prior to the separation of lander of from orbiter. The Vikram lander Named after Dr. Vikram A Sarabhai. The father of Indian Space Programme. It’s designed to function for one lunar day which is equivalent to 14 earth days. The Vikram lander has the capability to communicate with IDSN near Bangalore as well as with orbiter and Rover Pragyaan. The lander is designed to execute a soft landing on the lunar surface. Rover-Pragyaan The Pragyan Rover is a 6 wheeled robotic rover and contains two payloads. It can travel up to 500 meters and leverages solar energy for its functioning. Pragyaan rover can only communicate with lander Vikram. The objective of the mission is to demonstrate the soft landing on the moon’s surface and do different experiments on the moon’s surface which will help us to know better about Moon’s surface composition and early history of the moon and solar system. And also to find out the presence of water on the south polar region. The mission has an allocated cost of 978 crore rupees (141 million US$). The launch date was set to 15 July, but a technical snag was observed in launch vehicle system before an hour of launch time. So the launch was rescheduled on 22nd July. The Chandrayaan-2 was ready to launch from 2nd launch pad of Satish Dhawan Space Center at Sriharikota. ISRO successfully launched the Chandrayaan-2. On 2nd September Vikram was going to say goodbye to the orbiter. The Vikram lander was separated from the orbiter. After that series of two deorbit burn was used to decrease the orbit of Vikram. today, Vikram was going to soft-land on the Moon’s surface. Two landing sites were selected. Each with a landing ellipse of 32x11 km. The prime site is on a high plain between the two craters Manzinus C and Simpelius N at a latitude of 70 degrees south. Vikram began its descent by using its onboard computers on Vikram with the mission control unable to make corrections. In next fifteen minutes vikram was about to land on Moon’s surface. |
