Former ISRO chief, Madhavan Nair, expressed optimism about reviving Chandrayaan-3’s Vikram lander and Pragyan rover after their two-week slumber on the moon despite the fact that, worryingly, they’ve failed to reply. Nair in contrast the method to thawing one thing from a deep freezer, emphasising that the lunar floor’s excessive chilly, plummeting to under -150 levels Celsius, poses a major problem.
“Vikram Lander and Pragyan Rover have been in deep sleep for nearly two weeks now. It’s nearly like taking out one thing from the freezer after which making an attempt to make use of it. The temperatures would have gone past -150 levels Celsius,” Nair advised ANI.
Regardless of the daunting situations, ISRO is making ready to awaken Vikram and Pragyan from their “sleep mode” after exposing them to the solar’s rays, following the profitable completion of their preliminary duties. Vikram’s historic touchdown close to the moon’s south pole on August 23 marked a pivotal second for the mission.
Navigating Lunar Challenges
Nair additional expressed concern concerning the survival of batteries, electronics, and mechanisms within the moon’s harsh surroundings, the place temperatures can attain -150 levels Celsius. Nevertheless, he reassured that intensive floor testing had been carried out to make sure their performance. He famous, “However nonetheless, we have now to maintain our fingers crossed.”
Nair defined that if the rover will be activated, it will present beneficial information on the moon’s floor close to the south pole. Pragyan, the rover, might cowl a ways over the following 14 days.
In the meantime, former ISRO scientist Tapan Mishra termed even the lander’s revival as a possible miracle. The unique design allowed for simply 14 days of operation, and the moon’s southern pole can expertise temperatures as little as -200 levels Celsius. Mishra remained hopeful, suggesting that ISRO possible applied sturdy thermal administration measures.
After their touchdown, Vikram and Pragyan spent roughly 14 days on the lunar floor, conducting numerous duties similar to detecting sulphur and different components, recording temperatures, and monitoring lunar actions. In lunar phrases, that is equal to 2 weeks on Earth.
Chandrayaan-3’s major targets included reaching a protected and tender touchdown, rover exploration of the moon’s floor, and conducting in-situ scientific experiments. In early September, Vikram and Pragyan have been positioned in “sleep mode.”
The ISRO crew faces the problem of reviving and sustaining these lunar explorers within the moon’s excessive situations, with hopes of continuous their groundbreaking mission.
