Bengaluru, September 7: Indian Space Research Organisation or ISRO lost communication with Chandrayaan 2 spacecraft when the lander 'Vikram' was 2.1 kilometres away from the Moon surface. The lander 'Vikram' began its final descent on the South Pole of the Moon at 1:38 am on Saturday. The lander was moments away from making a soft-landing on the Moon surface when it stopped sending signals. Reacting to the unfortunate development, Prime Minister Narendra Modi asked ISRO scientists to be courageous.

"There are ups and downs in life. This is not a small achievement. The nation is proud of you. Hope for the best. I congratulate you. You all have done a big service to the nation, science and mankind. I am with you all the way, move forward bravely," PM Modi told scientists at the ISRO Centre in Bengaluru. PM Modi patted ISRO chief Dr K Sivan's back even as scientists were seen tensed as the lander lost communication with the ground station.

"Vikram Lander descent was as planned and normal performance was observed up to an altitude of 2.1 km. Subsequently, communication from Lander to the ground stations was lost. Data is being analyzed," Dr Sivan said. ISRO also called off the planned press conference. Asked if Vikram lander crashed, ISRO scientist Deviprasad Karnik said: "Data is being analysed. We don't have any result yet. It takes time. We are not sure." While the status of Vikram lander remained unknown, Indians flooded Twitter with congratulatory tweets for ISRO scientists' hard work.

Tweets on Chandrayaan 2 Mission:

The heavy-lift rocket GSLV MkIII-M1, nicknamed 'Baahubali' successfully put Chandrayaan 2 spacecraft into Earth's orbit on July 22. The spacecraft was initially scheduled to be launched on July 15. However, the flight was postponed after a technical snag was detected an hour before the rocket lift-off. The issue was later rectified by the ISRO. Chandrayaan 2 entered Moon's orbit on August 2.

Ahead of the Moon landing, a series of orbit manoeuvres were performed on Chandrayaan 2 to lower the altitude of the spacecraft.  Chandrayaan 2 spacecraft left Earth's orbit and successfully entered the Lunar Transfer Trajectory (LTT) on August 14.
