It was the solar wind that contributed to the most humidity of lunar soil.
China’s Chang’e 5 lunar lander has found the first-ever on-site evidence of water on the surface of the moon, lending new evidence to the dryness of the satellite.
The study published on Saturday in the peer-reviewed journal Science Advances revealed that the lunar soil at the landing site contains less than 120 parts-per-million (ppm) water or 120 grams water per ton, and a light, vesicular rock carries 180 ppm, which are much drier than that on Earth.
The presence of water had been confirmed by remote observation but the lander has now detected signs of water in rocks and soil.
The restoration and redevelopment of the decades-old Calve College Government school, a landmark that occupies a prominent place in the city’s history is nearing completion. The Puducherry Smart City Development Limited (PSCDL), which has taken up the restoration, has planned to complete the work by the first week of July. The Indian National Trust for Art and Cultural Heritage (INTACH) is the architectural consultant for PSCDL, while Puducherry Technological University (PTU) is the structural consultant. The work commenced in August 2021 and costs ₹4.75 crore.
