As the Chandrayaan-3 is set to touch down the lunar south pole, prayers are offered in India and beyond for the mission’s success
India’s mission to the Moon could be about to make history, with a probe expected to touch down near the lunar south pole in less than seven hours. The Lander module of the Chandrayaan-3 spacecraft will attempt the landing at 6.04 pm Indian Standard Time on Wednesday.
If successful, the probe will be the first to soft-land in the Moon’s southern polar region, placing India on the short list of countries who have mastered the technology of soft landings on the lunar surface, after the Soviet Union, the US and China.
The landing will be attempted just days after Russia’s probe, Luna-25, crashed into the Earth’s satellite after it failed to shut down its engines on time, and veered from its intended orbit.
In 2019, India attempted a similar mission, but the Chandrayaan-2, too, crashed just minutes before its scheduled landing. Learning from past failures, scientists at the India Space Research Organisation (ISRO) had redesigned the spacecraft to ensure a successful descent.

While so far the third mission was going smoothly, according to the Indian space agency, the last leg of the journey will be crucial. Scientists behind the mission refer to this phase as “20 or 17 minutes of terror” largely because, in these last moments, the entire process will become autonomous. The Vikram lander has to fire its engines at the right times and altitudes, use the correct amount of fuel, and scan the lunar surface for any hills or craters before finally touching down.
If any factor regarding the lander module appears unfavourable, the landing will be postponed to August 27, Nilesh M Desai, the director of Space Applications Centre-ISRO, told ANI news agency on Monday. According to him, the decision on whether to make the landing or not will be made two hours before the scheduled time, “based on the health of the lander module and the conditions on the Moon”.
