Early on Wednesday, "Vikram", the lander, was moved to the threshold location from where it descends towards the lunar surface between 1 am and 2 am on September 7, and attempt to land close to the Moon's South Pole between 1: 40 am and 1:55 am.

The ISRO said the manoeuvre began at 3.42 am as planned, using the onboard propulsion system and it took all of nine seconds. It is now circling the Moon in an orbit 35 km X 101 Km as compared to its previous orbit of 104 km by 128 km on Tuesday. "The Lander is scheduled to powered descent between 0100 - 0200 hrs IST on September 07, 2019, which is then followed by touch down of Lander between 0130 - 0230 hrs IST", stated ISRO. The touchdown on the Moon's south polar region will be between 1.30 a.m. - 2.30 a.m., ISRO said. Following the landing, the rover "Pragyan" will roll out from "Vikram" between 5.30 am and 6.30 am and carry out experiments on the lunar surface for a period of one lunar day, which is equal to 14 Earth days.

Chandrayaan2 is India's second mission to the moon and comprises a fully indigenous orbiter, lander and rover.

Soon after 'Vikram's nudge to the threshold position, Dr Sivan speaking exclusively to this newspaper, said: "We have done all the tests and simulations to achieve a ideal landing on September 7". On Monday afternoon, the Vikram got separated from its mother spacecraft Chandrayaan-2. Chandrayaan-2, however, will continue with its mission for one year. "I am sure it will be a 100 per cent success", he said.
