ISRO chief K Sivan on Saturday said that the Chandrayaan-2 mission was still on track despite some setbacks during the soft-landing on September 7 and said that only a small part of the communication was lost. ISRO's Lunar Mission to the moon's South pole was cut short when Indian space agency's Deep Space Antenna lost communication with Chandrayaan-2's lander- Vikram as it descended towards the lunar surface. Chandrayaan 2 aimed at soft-landing on the moon, making India the fourth country to do so. K Sivan had earlier broken down in front of Prime Minister Modi following which he was hugged and consoled by PM Modi, who also had some encouraging words for ISRO's brave scientists.

'Mission not a failure', says K Sivan

The ISRO chief explained the four phases that were involved during the descent and said that the last phase was not executed properly, resulting in the snag.

K Sivan hailed PM Modi and said that he was a source of inspiration for all the scientists. Speaking about the Chandrayaan-2 mission, K Sivan revealed that there were two components of the mission - science and technology demonstration. Science was to do with the orbiter while the technology part was to do with the lander and the rover. K Sivan further revealed that there were advanced payloads that were carried in the orbiter and said that ISRO had introduced a new payload, a one that was never attempted before, that can identify the depth of water and ice on the surface of the moon. The ISRO chief said that the resolution provided by Chandrayaan-2 was fifty times more than that provided by Chandrayaan-1. K Sivan said that the orbiter was functioning very well and that the science mission was complete. He further added that data obtained from the payloads in the orbiter will be used to analyze data. K Sivan said that even the technology demonstration was close to success as they managed to go upto 2 km from 30 km and said that even the technology demonstration was also 95% complete.
