NATIONAL: 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.

“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’.

On the other hand, Union Minister of State Science & Technology Dr. Jitendra Singh tweeted, “Chandrayaan 3 Update: For the last several hours, Team #ISRO making best effort to establish contact with the Vikram lander and Pragyan rover to ascertain their wake-up condition after the sunrise on Moon. As of now, no signal has been received from them so far. This could be possibly because of prolonged spell of cold weather conditions up to -150 degrees C during the just concluded lunar night of 14 Earth days. However, efforts to establish contact shall continue.”

Meanwhile, 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.
