Indian Space Research Organisation (ISRO) chairman K Sivan Saturday said that the space agency will continue trying to establish link with the lost Vikram lander for the next 14 days. He further added that the estimated life of the Chandrayaan-2 Orbiter is now seven years instead of one year.
"The last portion was not executed the right way, in that phase only we lost the link with the Lander, and could not establish communication subsequently. Right now the communication is lost. We will try to establish a link for the next 14 days," Sivan said in a televised interview to Doordarshan.
He added that 90 to 95 per cent of the mission objectives have been accomplished.
Chandrayaan-2 comprised of three parts – the Orbiter, Lander (Vikram) and Rover (Pragyan). In the last stage snag, the communication link between the moon lander Vikram and the moon orbiter was snapped as the former was descending towards the moon's South Pole early on Saturday.
“The precise launch and mission management has ensured a long life of almost seven years instead of the planned one year. The Vikram 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. The success criteria was defined for each and every phase of the mission and till date 90 to 95% of the mission objectives have been accomplished and will continue contribute to Lunar science, notwithstanding the loss of communication with the Lander,” it said.
