ISRO on Friday said it has made efforts to establish communication with its lunar mission Chandrayaan-3's lander Vikram and rover Pragyan to ascertain their 'wake-up condition' after they had been put into sleep mode early this month -- but no signals have been received from them as of now.
Attempts to make contact with the lander and rover will continue, the national space agency said on social media platform X.
With dawn breaking on the Moon, ISRO attempted to reestablish communication with the lander and rover, 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. However, their receivers were kept on.
"Efforts have been made to establish communication with the Vikram lander and Pragyan rover to ascertain their wake-up condition. As of now, no signals have been received from them. Efforts to establish contact will continue." ISRO said in a post on 'X'.
“We have put both the lander and rover on sleep mode because temperature would go as low as minus 120-200 degree celsius. From September 20 onwards, sunrise will be going on at the Moon and by September 22 we hope that the solar panel and other things will be fully charged, so we will be trying to revive both the lander and rover, ” ISRO’s Space Applications Centre Director Nilesh Desai had told PTI on Thursday.
