The Indian Space Research Organisation (ISRO) is set to re-establish communication with Chandrayaan-3's Vikram lander and Pragyan rover on Friday, September 22. Vikram and Pragyan had entered sleep mode for the lunar night after completing a successful hop experiment. The two-week lunar night meant no sunlight to power the solar-dependent systems. However, ISRO kept the lander's receivers active for data collection. Now with the lunar day starting, ISRO aims to wake up the spacecrafts and restart communications. The Chandrayaan-3 mission components rely on solar panels for energy. The earlier 14-day lunar day was their primary operational phase which allowed functioning with steady sunlight. But the lunar night posed a challenge with temperatures dropping to minus 180 degrees Celsius.
