ISRO scientists on Monday, September 2, successfully separated Lander Vikram from the orbiter of Chandrayaan-2. According to ISRO, the process of separating the lander ‘Vikram’ from the arbiter was started at 12.45 pm. At 01:15 in the afternoon, the lander broke away leaving ‘Vikram’ arbiter. Now as per the schedule, the lander ‘Vikram’ will land on the lunar surface at 1.55 am on September 7.

ISRO will pass through two orbital changes, tweeting that the lander ‘Vikram’ is currently circling the 119km x 127km orbit of the moon. At the same time, the arbiter of Chandrayaan-2 is circling in the same class in which he entered on Sunday. According to scientists, two orbital changes will be made with the lander ‘Vikram’ before landing on the lunar surface. Lander ‘Vikram’ will be 35×97 in the nearest orbit of the moon on 04 September.

Yesterday, the orbit change was made by the scientists of the Indian Space Research Organization (ISRO) successfully orbiting the lunar orbit at 6.21 pm on Sunday. This was the fifth and final change in the orbit of the orbit since it reached the moon’s orbit. It took 52 seconds to change class. Now Chandrayaan is just 109 km away from the moon.

Separation was quite fast, according to ISRO scientists, the separation on September 2 was very fast. It separated at the same speed as a satellite launcher differs from a rocket. To isolate the integrated spacecraft, ISRO scientists gave command from Earth, after which the onboard system executed it. The orbiter will carry out various experiments, orbiting the moon for almost a year.

The dual challenge before scientists is now that Lander Vikram has started moving towards the moon with the knowledge rover inside him. Now scientists will have to work together for the accuracy of the arbiter and the lander Vikram. After September 4, for the next three days, the lander will revolve in the nearest 35×97 orbit near Vikram Chand. During this time Vikram Lander and Pragyan Rover will be investigated. In this way, on September 07, at 1:55 am, the lander Vikram will land on the south pole of the moon.

Soft landing will be extremely challenging According to ISRO scientists, the soft landing of Chandrayaan-2 on the moon will be very challenging. On September 7, the rover will step on the moon with Recognition. The lander Vikram will successfully land at about 70 ° south latitude in the plains between two pits, Manzinus C and Simpelius N. After landing on the moon, the rover will also be separated from the lander. The landing of Rover Pragya with lander is a big challenge for ISRO for this reason as ISRO has not done such an experiment till now.

Pragyan Rover will cover a distance of 500 meters. Pragyan will cover a total distance of 500 meters in 14 days. After this, it will become inactive. The Soviet Union, America, China, etc. have sent five rovers to the moon before the discovery. On the other hand, the orbiter will be orbiting the Moon at an altitude of 100 km. The orbiter will remain active in the Moon’s orbit for one year. The lander Vikram will have a speed of two meters per second when landing on the lunar surface. During this time, scientists will reduce its speed. 15 minutes of this entire process will be extremely stressful.

Pragyan will come out of the lander two hours after landing. After about two hours of landing, the six-wheeled rover from the lander Vikram will step on the surface of the moon. On September 7, at 5.05 am, Rover Pragyan’s solar panel will open, through which it will get the energy to work. Explain that this is the second lunar expedition of India. In the year 2008, India sent the mission Chandrayaan-1. The orbiter carried out experiments while orbiting the moon for about 10 months. The credit for the discovery of water on the moon goes to this expedition to India. Now through mission Chandrayaan-2, ISRO will explore the availability of minerals and other chemical components on the moon.
