- ISRO chairman K. Sivan said – Chandrayaan-2 will enter the moon’s orbit on August 20
- ISRO launched Chandrayaan-2 on July 22, so far its activities remain normal
New Delhi: Chandrayaan-2 left the Earth’s orbit at 2.21 am on Wednesday morning. Now it has left to enter the Moon’s orbit. This process is called Trans Lunar Insertion (TLI), in which ISRO has been successful. Earlier, Chandrayaan-2 remained for 23 days in the Earth’s orbit and made four rounds of the planet. ISRO launched Moon Mission on 22 July from Sri Harikota in Andhra Pradesh.
ISRO chairman K. Sivan said that Chandrayaan-2 will take 6 days to reach the moon’s orbit. Chandrayaan-2 has successfully entered the Lunar Transfer Trajectory System. On 20 August, Chandrayaan-2 will enter the Moon’s orbit. The distance between the Earth and the Moon is 3.84 lakh kilometers. According to ISRO, the fire in the vehicle’s engine ignited for 1203 seconds while it left its last orbit of Earth.
Chandrayaan-2 will reach the moon on due date
Despite extending the mission’s launch date, Chandrayaan-2 will reach the moon on the fixed date i.e. 7 September. The purpose of delivering it on time is that the lander and rover can work according to the schedule. To save time, Chandrayaan made one less round of the Earth. First five rounds were to be made, but later the number was reduced to four. Its landing is fixed at a place where there is more sunlight. The lights will start to grow dim after September 21. The lander-rover has to work for 15 days, so it is necessary to arrive on time.
Chandrayaan-2 weighs 3,877 kg
Chandrayaan-2 was launched with India’s most powerful GSLV Mark-III rocket. This rocket has three modules: Orbiter, Lander (Vikram) and Rover (Pragyan). As part of this mission, ISRO plans to land the lander at the south pole of the moon. This time Chandrayaan-2 weighs 3,877 kg. This is almost three times more than the Chandrayaan-1 mission (1380 kg). The speed of the rover inside the lander is 1 cm per second.
What is the Chandrayaan-2 mission?
Chandrayaan-2 is actually a new version of the Chandrayaan-1 mission. This includes the orbiter, the lander (Vikram) and the rover (Pragya). Chandrayaan-1 had only the orbiter, orbiting the moon. India will land a lander on the lunar surface for the first time through Chandrayaan-2. This landing will be at the south pole of the moon. With this, India will become the first country to land on the moon’s south pole.
What work will the orbiter, lander, and rover do?
The orbiter will work for one year after reaching the moon’s orbit. Its main purpose is to communicate between the Earth and the lander. The orbiter will prepare the map of the surface of the moon so that scientists get a better understanding of how the moon was formed and how it has evolved and developed. At the same time, the lander and rover will work on the moon for one day (equivalent to 14 days of Earth). The lander will check whether earthquakes occur on the moon. Whereas, the rover will detect the presence of mineral elements on the lunar surface.
Chandrayaan-2 was scheduled to be launched for first time in October 2018
ISRO was first to launch Chandrayaan-2 in October 2018. Later its date was extended to 3 January and then to 31 January. It was later postponed until July 15 for other reasons. During this time the weight of Chandrayaan-2 also increased due to the changes. In such a situation, some changes were also made in GSLV Mark-3.
