Why in news
Researchers from the Physical Research Laboratory (PRL) discovered a close chemical relationship between soil at Shiv Shakti Point (Chandrayaan-3 landing site) and the ALHA 81005 lunar meteorite found in Antarctica.
Background
The study suggests the soil at Shiv Shakti Point is chemically similar to the ALHA 81005 meteorite, which fell in Antarctica approximately one million years ago. The findings support the lunar magma ocean theory and evidence of crustal material redistribution by impact events.
