Lunar Orbiter of NASA Detects India's Historic Moon Landing Location
In an exciting development, India's Chandrayaan-3 mission, comprising the Vikram lander and Pragyan rover, has entered a sleep mode during the lunar night. The lunar night, which typically lasts approximately two weeks, is a period of darkness on the Moon's surface.
The mission, which successfully landed on the Moon's south pole on August 23, 2022, has been exploring the dusty terrain of the Moon's surface, and the rover has been measuring the temperature profile of the previously unexplored region near the Moon's south pole. Traces of sulfur and other chemical elements have been found on the lunar surface by the Chandrayaan-3 rover, providing valuable insights into the Moon's geology.
NASA's Lunar Reconnaissance Orbiter (LRO) recently spotted the Chandrayaan-3 lander on the Moon's surface on August 27. The LRO image shows a slightly brighter circle of dust around the lander, caused by the rocket plume interacting with the Moon's fine-grained regolith.
The Chandrayaan-3 lander's solar panels convert sunlight into electricity, but during the lunar night, they are unable to do so. This necessitated the mission entering a sleep mode to conserve energy. The onset of a new lunar day is scheduled for September 22, according to the Indian Space Research Organisation (ISRO).
The ISRO plans to wake the Chandrayaan-3 lander and rover up on September 22. The mission was originally designed to last for a lunar day (or the equivalent of 14 days on Earth). However, given the recent context, the mission would have been in sleep mode for about two weeks, likely waking up around mid-July 2025 to resume operations.
India's Chandrayaan-3 mission marks a significant achievement for the country, as it is the first to land on the Moon's south pole and the fourth country to achieve a successful Moon landing after the Soviet Union, the U.S., and China. The mission's findings are expected to contribute significantly to our understanding of the Moon's geology and potentially pave the way for future lunar exploration.
