Why Vikram Lander, Pragyan Rover may not come back from dead as ISRO tries to revive Moon mission

In a bid to revive the Chandrayaan-3 mission on the lunar surface, the Indian Space Research Organisation (ISRO) is facing a daunting challenge as they attempt to reestablish communication with the dormant Vikram Lander and Pragyan Rover. Despite their best efforts, no signals have been received from the lunar duo, leaving ISRO in a race against time to awaken these vital components of the Chandrayaan-3 mission on the Moon.

ISRO's determined efforts to contact the Vikram Lander and Pragyan Rover to assess their operational status have, so far, yielded no results. In a recent statement, ISRO reaffirmed their commitment to continuing their relentless pursuit of reestablishing contact with these lunar explorers, PTI reported.

The Chandrayaan-3 mission had successfully landed both the Vikram Lander and the Pragyan Rover on the Moon's surface on August 23. Their landing site, known as the 'Shiv Shakti Point,' promised to be a hub of scientific discovery.

However, the moon's extreme environmental conditions posed a formidable challenge. As Suvendu Patnayak, a former deputy director of the Pathani Samanta Planetarium in Bhubaneswar, explained, the lunar nighttime temperatures plummet to a bone-chilling -250 degrees, rendering electronic components vulnerable. The Vikram Lander and Pragyan Rover were designed to function optimally for just 14 days on the lunar surface, operating exclusively during the moon's daytime when sunlight was available.

The reason has to do with the harsh weather conditions on the Moon, especially the extreme cold that sensitive electronic components on these machines cannot tolerate. "It is very difficult for a few electronic components to work in such a huge range of temperatures. So, it was expected it
