No sign of Vikram, Pragyan waking up, but Isro hopeful

India's space agency, ISRO, has not received any communication from the Chandrayaan-3 lander Vikram and rover Pragyan, despite efforts to revive their systems. The success of the mission has already been achieved, with all objectives met. The biggest challenge for the lander and rover to wake up again is the survival of electronic components in the extreme cold temperatures of the lunar night.
