Chandrayaan 2: Lunar Mission launched by ISRO in July 2019 | mod-digitech.blospot.com

Chandrayaan 2:

Chandrayaan 2 is an Indian Lunar mission launched by Indian Space Agency ISRO whose aims to go where no country has ever gone before - the Moon's South polar Region.

Why Chandrayaan 2:

Moon is the Natural Satellite of Earth and it is nearest planet to earth. Lunar South pole that remains in shadow is much larger than the north pole. earlier evidence of water molecules discovered by Chandrayaan 1. Through this mission Scientist wants to know about the presence of water as well as study of material composition of lunar surface. The new aspects of this mission is that the Chandrayaan 2 will attempt to soft land the lander Vikram and Rover Pragyan in a high plain between two craters, Manzinus C and Simpelius N.

Mission: Chandrayaan 2

Launcher and the Spacecraft:

Launcher: Chandrayaan 2 mission waas launched by Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III). This three stage Vehicle is India's most powerful launcher to date, and is capable of launching 4-ton class of satellite to the Geosynchronous Transfer Orbit (GTO).

GSLV Mark-III

Orbiter: Orbiter will revolve around the moon at the height of 100 Km from moon Surface and will observe the Lunar Surface and relay communication between earth and Chandrayaan 2 Lander- Vikram. It's Weight is 2379 Kg and It can Generate 1000 W Electric Power.

Orbiter

Vikram Lander: The Lander of Chandrayaan 2 is named Vikram after Dr. Vikram A Sarabhai, The father of Indian Space Programme. It is designed to execute a soft landing and can work for 1 lunar day which is equivalent to about 14 Earth days. It has capability to communicate with IDSN as well as with the Orbiter and Rover. It's Weight is 1471 Kg and It can Generate 650 W Electric Power.

Pragyan Rover: The Rover is a 6 Wheeled robotic Vehicle named Pragyan , which translates to 'Wisdom' in Sanskrit. It can Travel up to 500 m and uses Solar Energy for working. It can only communicate with the Lander. It's Weight is 27 Kg and It can Generate 50 W Electric Power.

Sequence of Events:

• Prime Minister Manmohan Singh approved the Chandrayaan 2 Lunar Mission on 18th September 2008.
• approx 11 years were taken by ISRO to designed and testing of whole mission.
• Initially the launch date was scheduled for 14th July 2019, 21:21 UTC (15 July 2019 at 02:51 IST local time) with the landing expected on 6 September 2019 but due to technical fault launch was rescheduled for 22 July 2019 at 09:13 UTC (14:43 IST).
• from 24th July 2019, 9:22 UTC to 13th August 2019, 20:51 UTC, Orbiter maneuvered from 1st Orbit raising to 5th Orbit raising and trans lunar injection was done on 13th August 2019.
• from 20th August 2019, 3:32 UTC to 1st September 2019, 12:51 UTC, Orbiter maneuvered from 1st lunar bound to 5th lunar bound in lunar orbit.
• 2 September 2019, 7:45 UTC, Vikram separated from Orbiter.
• on 6 September 2019 Trajectory deviation started for Vikram lander for soft landing but at altitude of 2.1 Km telecommunication signal lost from earth seconds before touchdown.
• as per current updates from ISRO, orbiter send images of moon's surface and ISRO found the exact location of Vikram Lander and no damage occured to lander while landing but it is situated in tilt position at moon's south pole.
• ISRO will try to make communication from Vikram in next 14 Days reported by ISRO.
