ISRO hopes to wake up Chandrayaan-3’s Vikram and Pragyan on September 22


The Indian Space Research Organization (ISRO) is considering awakening Chandrayaan-3’s Vikram lander and Pragyan rover as dawn breaks on the moon on September 22.

The lander and rover went to sleep after the expiration of one lunar day (14 Earth days).

On September 2, Pragyan was put into sleep mode and two days later on September 4, the space agency also put Vikram into sleep mode by switching off its payload. However, the receivers of both Vikram and Pragyan have been kept on.

Now, once sunlight returns to the moon on September 22, ISRO hopes that its solar panels will be charged and it will be able to establish contact with the two.

Once the Sun sets over the Moon after completing one lunar day, the temperature can drop to minus 200 degrees Celsius.

“The temperature there goes down to -200 degrees [Celcius], In such an environment, there is no guarantee that the batteries, electronics will survive, but we did some tests and we felt they would survive even in such harsh conditions,” Mr Somnath had said earlier.

Since landing on the Moon on August 23, Vikram and Pragyan have made several in-situ measurements, such as confirming the presence of sulfur in the region, and detecting the presence of minor elements.

Vikram also achieved an important milestone as it successfully conducted a hop experiment when the lander started the engines on command, raised itself about 40 cm and landed safely at a distance of 30-40 cm.

This successful HOP experiment and kickstart could have a significant impact on future missions that are launched with the aim of bringing back samples from the Moon and future human missions to the Moon.

If ISRO manages to wake up Vikram and Pragyan, it will be a bonus for the space agency as it will hope to conduct some more experiments on the Moon.

The Chandrayaan-3 spacecraft was launched on July 14 and landed on the lunar surface on August 23, making India the fourth country to successfully land on the Moon, and the first to touch the lunar polar region.
