After Chandrayaan-2's lander Vikram lost communication with ISRO's Mission Control Centre in Bengaluru on Saturday, the ISRO Chairman Dr. K Sivan speaking exclusively to Republic TV elaborated on the 47 days of the journey towards the moon.
He spoke about the advanced technology used in Chandrayaan 2 that would identify ice and water on the moon's lunar surface and that ISRO performed complex maneuvering throughout the mission.
He said, "The journey towards the moon was fantastic, we had 47 days of travel. This particular mission had two parts, the science part mainly concentrated on the orbiter, we could successfully put the orbiter around the moon by 100-kilometer orbit. The instruments that we put in the orbiter is something new, which no country has, because of which you can penetrate sub-surface of the lunar region and can identify ice and water, which is the main advantage. We have done our job very well, we are fully satisfied."
"Every operation and moments we were monitoring, we were executing it with precision. We did a very complex maneuver, we placed the orbiter on the right orbit. Now next was to bring the technology demonstrater. We had four phases of the mission, we could complete 3 phases successfully, in the last phase we lost the communication with the lander. Otherwise, it is 95% success. Total Chandrayaan 2 mission is almost 100% success. We have been handling these kinds of projects, none of these projects are easy. Mainly the pressure is because the duration is more, otherwise the tension, anxiety is similar to any other mission," he added.
Sivan further said informed that the high-resolution camera will create images that no country has ever created and would give "accurate information" about the mapping of the lunar surface.
He said, "We had a chance to show the area of concern and interest to students. We are excited to have the children with us. The contribution that India has made is open to the global scientific community. I am just the head of the organisation, I just overview the activity and ensure the project was finished. This will give further insight into the science of the moon, especially the lunar region. We have our orbit going in the polar orbit. We can understand about water and ice even 10 meters below the moon surface. The orbiter high-resolution camera imaging will create images with 32 cm higher resolution which no other country has right now, the image will give accurate information about the mapping of the lunar surface, scientists would be very curious to know about this data."
Earlier on Saturday morning at 1:50 AM when Vikram was scheduled to land, ISRO's Deep Space Antenna lost communication with Chandrayaan-2's lander- Vikram as it descended towards the lunar surface. The lander had descended from 30 km to 2km smoothly. During the final smooth braking stage, it had lost communication with Mission Control. Vikram was aimed at soft-landing on the moon, making India the fourth country to do so.
