However, the ISRO scientists kept their hopes and continued to send signals from its Deep Space Communication Center.
There will be one more more orbit manoeuvre on Sunday to make the spacecraft enter its final orbit, passing over the lunar pole at a distance of about 100 km from the Moon's surface. According to the Indian Space Research Organisation (ISRO), the lander Vikram and rover Pragyaan were supposed to be functional only for 14 days from the day of their touchdown.
ISRO is racing against time to re-establish contact with Chandrayaan 2 Vikram lander before September 21 as it marks the beginning of the lunar night. The images were captured by NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft during its flyby on September 17, the United States space agency said. Isro is trying to understand what happened during the landing on September 7, Somanath told reporters after inaugurating an industrial facility at Devanampalayam, Kinathukadavu to manufacture rayon-based carbon fabric to be used in rocket nozzles.
Meanwhile, a national committee of experts, comprising academicians and ISRO scientists, are analysing the cause of the communication loss with the lander. Temperatures could drop to as low as short 200 degrees Celsius during the lunar night. It was close to lunar sunset when the orbiter released, which means large parts of the area were in shadow, the report said.
The nights on the Moon can be very cold, especially in the south polar region where Vikram is lying. But if ISRO can't establish contact with Vikram soon, it'll need to bid adieu to the lander. It has been nearly two weeks after Vikram Lander lost connection with ISRO's ground station.
In the early long stretches of September 7, ISRO's plan to dedicate land Chandrayaan-2's Vikram module on the lunar surface turned out poorly per content. Performance of all orbiter payloads is satisfactory, " the agency said.
The Chandrayaan -2 mission did not shape up as ISRO had planned. These included a position correction, so that its legs, which were horizontal to the lunar surface, would be pointing downwards, to enable a landing on its feet. ISRO added that initial trials for orbiter Payloads were completed successfully.
