New film retells how India built its first Antarctic base

'Miracle in Antarctica', a new film, chronicles the building of Dakshin Gangotri, India's first scientific base on the frozen continent. Producer Sourabha Rao, a Bengaluru-based writer and filmmaker, says the 1983-84 project was achieved at a remarkable pace within a single Antarctic summer. The film is directed by her husband, Santosh Saligram, and revisits why the expedition still matters.
