The Pragyan rover on Chandrayaan-3 has entered “sleep mode” after successfully completing its lunar missions. This accomplishment comes a little more than a week after India made history by landing safely on the south pole of the moon, marking the country’s groundbreaking success in space exploration.
The beginning of the moon’s 14 Earth days of continuous sunshine was chosen as the time for Chandrayaan-3’s lunar landing on August 23. On September 6, dusk is anticipated on the lunar surface, which poses a substantial difficulty. Both the Lander and Rover’s batteries will be discharged during this lunar night, which lasts 14 Earth days and is marked by surface temperatures that are below -100 degrees Celsius.
Although the mission is only supposed to last 14 days, there is hope that it will last longer if the batteries in the Rover and Lander can recharge when the sun rises again over the moon’s horizon.
The Rover has completed its assigned responsibilities and is currently safely parked in sleep mode, according to a statement from the Indian Space Research Organisation (ISRO) on X (formerly Twitter). Data from the instruments, including the APXS and LIBS payloads, is still being relayed to Earth by the Lander even though they have been shut down.
The solar panel is now positioned to catch sunlight for the next lunar dawn, which is anticipated on September 22, 2023, and the battery is currently completely charged. Hopes for a successful reawakening and the possibility of subsequent assignments are increased by the receiver’s continued activity. Otherwise, these lunar adventurers will continue to represent India on the moon forever, and it is unknown what will become of them.
