NASA organizes a space settlement design contest for high school students and students from all over the world, including from India, participate in it. This year a team from Orissa won the grand prize. The 2009 contest page has this to say about it. (Some name corrections are made using a tathya.in article about this.)
The Grand Prize winning submissions for 2009 went to Eric Yam, Pooja Bhattacharya and Swastika Bhattacharya.
