Chandrayaan-3's moon lander and rover, Vikram and Pragyan, have not shown any signs of revival.
Efforts were made to establish contact with them after a new lunar day began on September 22, but no signals were received.
Former ISRO chairman AS Kiran Kumar stated that there is no hope of reviving the mission.
Chandrayaan-3 achieved a historic soft landing near the lunar south pole on August 23, making India the fourth nation to achieve this feat.
ISRO put the lander and rover into sleep mode on September 4 and 2, with the hope of reviving them during the next sunrise around September 22.
Both Vikram lander and Pragyan rover were designed to operate for one lunar day, approximately 14 Earth days.
ISRO officials have stated that Chandrayaan-3 accomplished its objectives, including demonstrating a safe and soft landing, rover movement on the moon, and in-situ scientific experiments on the lunar surface.
On September 4, Vikram lander exceeded its mission goals by conducting a successful 'hop' test, which has implications for future manned space missions.
On September 2, the rover completed all its tasks.
