Sunrise at Shiv Shakti Point, ISRO geared up to wake up Vikram, Pragyan


Both remained dormant for about half a month at the Moon’s Shiva Shakti Point, enduring cold temperatures reaching -200 degrees Celsius.

As the Sun rises over the moon’s south pole on September 21, the Indian Space Research Organization (ISRO) will again attempt to establish communication with its Chandrayaan-3 mission’s Vikram lander and Pragyaan rover.

Both remain dormant for about half a month, enduring cold temperatures reaching -200 degrees Celsius at the Moon’s Shiva Shakti point. However, their operational condition is expected to improve with the arrival of sunlight.

Government’s fact-checking report claims Chandrayaan-3 technician not paid

According to India Today, ISRO said that sunrise has now occurred at the Chandrayaan-3 landing site in the south polar region of the Moon. The agency is waiting for the batteries to be recharged. The report quoted officials as saying that they hoped to re-establish communication with Vikram and Pragyan soon.

According to Hindustan Times, Vikram and Pragyan were put to sleep in a phased manner from September 2, leaving the batteries charged by sunlight and orienting the solar panels in such a way that they would receive light in the morning. Sunrise is important because it will provide the heat needed for the lander and rover to function.

In an ideal scenario, when the command is fed to the lander and rover to bring the system back to life, the rover will again start moving around the lunar surface and the instruments on the lander will also repeat the process of collecting data. . , “We can only expect the instrument to be operational again on September 22,” ISRO Chairman S Somnath told the website.

Vikram lander and Pragyan rover have been conducting various experiments since landing on the moon’s south pole on August 23. They measured the electron density in the moon’s ionosphere and also took temperature readings of the lunar surface. Pragyan rover also captured the first image of Vikram lander on the lunar surface.

However, operations came to a halt due to the moonless night. Solar-powered batteries were not powerful enough to keep their systems running in the absence of sunlight.

Chandrayaan-3 mission made India the fourth country after the US, China and Russia to successfully land on the lunar surface and the first country to land on the lunar south pole.
