Chandrayaan 2, India’s second lunar exploration mission after Chandrayaan 1, was successfully launched on 22 July, 2019 at 2:43 pm IST. Let’s have a glance at some unexplored yet important facts of the mission.
- The total weight of Chandrayaan 2 is 3850 kg.
- Chandrayaan 2 was launched from second launch pad at Satish Dhawan Space Centre at Sriharikota in Nellore district of Andhra Pradesh.
- It was launched by a Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III).
- It consists of a lunar orbiter, a lander and a lunar rover.
- Chandrayaan 2 launch was originally scheduled on 14 July 2019 which was called off due to a technical issue.
- If landed successfully, India will become the fourth country to achieve soft landing on the moon after the USSR, US and China.
The mission is headed to the moon’s South Pole and has achieved an orbit 6000 km more than what was targeted. The spacecraft was injected into orbit at a perigee of 169.7 km and apogee of 45, 475 km. The apogee was more than what was targeted.
What makes the mission special is the fact that the Project Director and Mission Director are both women, Muthayya Vanitha & Ritu Karidhal respectively. Vanitha won the best woman scientist of India award in 2006 and also, she played a key role in the success of Mangalyaan in November 2013. Ritu Karidhal is usually named as the “Rocket Woman” of India. She was the deputy operations director for the Mangalyaan project in 2013-2014 and was working closely with Muthayya Vanitha all throughout the Chandrayaan 2 mission.
Objective of the Mission
Chandrayaan 2 has been launched with an aim to demonstrate the ability to soft land on the lunar surface and operate a robotic rover on the surface. Over the time, it will study the lunar topography, mineralogy, elemental abundance and signatures of hydroxyl and water ice. Chandrayaan 2 will also provide information about the location and abundance of lunar water for future exploration. It will also do 3D mapping of the topography of the South Polar Region and also, calculate its seismic activity.
The orbiter will orbit the Moon at an altitude of 100 km. It carries five scientific instruments, 3 of which are new, while 2 others are improved versions of those flown on Chandrayaan 1. The structure of the orbiter was manufactured by Hindustan Aeronautics Limited in 2015. The mission uses the Vikram lander and Pragyan rover.
The Vikram lander will detach itself from the orbiter and descend to a lunar orbit of 30 km with the help of its 800 N liquid main engine. After detaching, it will perform a comprehensive check of all its onboard systems. In addition, Pragyan will move on 6 wheels at the rate of 1 cm per second.
