Legacy in the Crater

＂Earth’s own experiment in planetary science.＂That’s how Dr. Reddiah Kosaraju-a marine biologist by training, a public servant by calling, and a cosmic thinker by nature-described Lonar Lake.Nestled in Maharashtra’s Buldhana district, Lonar is no ordinary lake. Formed by a meteorite impact over 50,000 years ago, it is the only known hyper-velocity impact crater in basaltic rock on Earth-a remnant of the ancient Deccan Traps. To most, it is a geological curiosity. To Dr. Kosaraju, it was a living laboratory.From his early days at the Zoological Survey of India to his doctoral work in Liverpool, Dr. Kosaraju’s scientific gaze was always expansive. At Lonar, he saw echoes of lunar basins and Martian plains. He was captivated by its rare minerals, its alkaline-saline waters, and the extremophile microbes that thrived there-organisms that might mirror life on other planets. It was his interest and passion.His work prefigured the interest of NASA and ISRO, who now study Lonar as a terrestrial analog for extraterrestrial craters. In many ways, Dr. Kosaraju’s insights anticipated the global relevance of Indian geoscience long before it became fashionable.
