Chandrayaan 3 made its footprint on the moon and carried out research as a boast to all Indians. In this case, isro chief somnath has given some exclusive information to our Asianet news agency about the return of the vikram lander and Prakyan rover, which are currently resting on the moon, on september 22. In a meeting with our Asianet news President Rajesh Kalara, isro Chief somnath shared the following… “Surviving the extremely low temperature on the lunar surface for a long time and ensuring that the computers work again will be a very difficult task, but the vikram lander and the Pragyan rover will be back in the sun in September. If they come alive once they land on them tomorrow on september 22, it will be a historic achievement," isro chief S Somanath said in an exclusive conversation with Asianet news Network Executive Chairman Rajesh Kalra.

"Recalling the sequence of events so far, isro initiated the "Sleep" mode for the vikram lander on september 5. Prior to this, a series of in-situ tests involving ChaSTE, RAMBHA-LP and ILSA payloads were successfully conducted at the new location. Later, the collected data was sent to Earth. "It was sent, which disabled the payloads. Significantly, the receivers on the lander were left operational," he said. Ahead of tomorrow, september 22nd, scientists are ready to begin re-energizing the equipment on both the lander and Pragyan rover. The success of this effort will depend on the ability of these instruments to withstand the extreme low temperatures that occur during lunar nights. Historical data from previous missions to the moon, nighttime temperatures on the moon are approximately minus "Indicates that temperatures can go as low as 200 degrees Celsius," he noted.

"With the confidence we have for Chandrayaan-3, the vikram lander and the Pragyaan rover, and the confidence we have in all other test programmes, we are confident that both will recover tomorrow. It is important that the rover and the lander in particular wake up from their slumber. The electronics in the computer must function in order to obey us and send commands". If that happens tomorrow, september 22, it will be historic. "Because surviving at such low temperatures for a long time and making sure the computers work again, it's going to be a very difficult task," Somanath said during his interview.

"Pragyan has been fully tested (for ultra-low temperatures). But for Vikram, I can't say that everything is tested. It's a very big object, undergoing such low-temperature testing. But many of the designs are the heritage of the designs inside the vikram lander and Pragyan, as Pragyan is the same, we at Pragyan We believe the test done is enough to give confidence to vikram as well,” he said. At the same time, he said, the moon still has enough fuel for some interesting experiments. The isro chief also confirmed that if the vikram lander module is reactivated in september 2022, more hop tests may be conducted.

"According to our estimate, there is about 90 kilograms of fuel left, which should be enough for some more interesting experiments," Somanath said. However, he also said that there are many challenges to this. "If the temperature goes below 180 degrees, the liquid doesn't remain, it becomes solid. And every pipeline becomes non-solid. It has to melt back into liquid. And with all our confidence we will definitely do something," he said.
