ISRO chief K Sivan confirmed that attempts are still being made to establish contact with the Vikram lander, after communication was lost on early Saturday morning while it was just 2.1 km away from the lunar surface while attempting its soft-landing. Sivan further informed that the attempts would be made to establish a link for the next 14 days - a lunar day - and a parallel search will be conducted by the orbiter.
Speaking to Doordarshan in his first interview after contact was lost with the lander, K Sivan said, "The science we are going to do won't be just for one year, it'll be for all seven years. Yes, right now the communication is lost but we will try to establish a link, that effort will be going on. We will try for the next 14 days. If at all we are succeeding, we will be able to operate and will get the required data. We will also parallelly search with the orbiter."
Updating on the Vikram lander, ISRO had stated that the Lander followed the planned descent trajectory from its orbit of 35 km to just below 2 km above the surface. "All the systems and sensors of the Lander functioned excellently until this point and proved many new technologies such as variable thrust propulsion technology used in the Lander."
In a statement released by ISRO on Saturday evening, Chandrayaan-2 mission has been termed as "a highly complex mission", adding that it represented a significant technological leap compared to the previous missions of ISRO.
Launched on July 22, Chandrayaan 2 brought together an Orbiter, Lander, and Rover to explore the unexplored south pole of the Moon, the statement further said. ISRO said that "it was a unique mission which aimed at studying not just one area of the Moon but all the areas combining the exosphere, the surface as well as the sub-surface of the moon in a single mission".
ISRO defined the success criteria for each and every phase of the mission and added that 90 to 95% of the mission objectives have been accomplished to date. It said that the mission will keep contributing to Lunar science in spite of the loss of communication with the Lander.
As ISRO official has assured that the Chandrayaan-2 orbiter is healthy and safe in the Lunar orbit after the Vikram lander lost contact with ground stations minutes before the touchdown on Moon's surface early on Saturday. ISRO Chief K Sivan announcing the development stated that the data is being analysed of the Lander. On September 2, ISRO successfully carried out the separation of lander Vikram (with rover Pragyan housed inside) from the Chandrayaan-2 orbiter.
