India is on the left half of the image, under the grey pall of pollution. The Himalayas and Nepal are on the right. The image is of a section of central UP. According to a database of PM 2.5 pollution produced by the WHO in 2014, 13 of the world’s 20 most polluted cities are in India. Delhi, Patna, Gwalior and Raipur are the top four in the list.
Scott Kelly, along with Russian cosmonaut Mikhail Korniyenko, has been in space since March 27, 2015, on a one-year mission to understand how the human body reacts to long-duration spaceflight. According to NASA, the science will be used to determine ways to reduce risks on future deep space missions such as a flight to Mars.
