Explanation: Astrobiology is the scientific study of the possible origin, distribution, evolution, and future of life in the universe,
including that on Earth, using a combination of methods from biology, chemistry, and astronomy. For the first time India is part of
Spaceward Bound programme, which funds expeditions to places with extreme climate conditions. Even as India prepares for a
second mission to Mars, a team of scientists from the National Aeronautics and Space Administration (NASA), the Mars Society
Australia and the Birbal Sahni Institute of Palaeobotany, Lucknow, will mount an expedition to Ladakh this August to study the
similarities of certain parts of the region’s topography and microbial life to Martian surroundings.
