Chandrayaan-3: With dawn breaking on the Moon, ISRO is now gearing up to try to reestablish communication with its lunar mission Chandrayaan-3's solar-powered lander Vikram and rover Pragyan, to revive them so that they can continue with scientific experiments. Both the lander and the rover were put into sleep mode earlier this month on September 4 and 2 respectively, ahead of the lunar night setting in on Earth's only natural satellite.
If the space agency is able to revive them, the information that is derived from experiments that could once again be conducted by the Chandrayaan-3 payloads would be a "bonus". The major challenge for ‘Vikram and Pragyan’ would be to come back in action after surviving the chilling -200 degree Celsius of temperature.
If the onboard instruments survive the low temperature on the Moon, the modules can come back to life and continue their mission to send information from the moon for next fourteen days. If things go as per the plan, the rover will start moving after the commands will be fed into the rover.
Later, the same procedure will be repeated on the lander module With sunlight back on the south polar region of the Moon, where both the lander and rover are located, and their solar panels expected to be optimally charged soon, ISRO is now slated to make efforts to establish contact with them again, check their health and ability to resume functioning, and try to revive them. "We have put both the lander and rover on sleep mode because temperature would go as low as minus 120-200 degree celsius.
