President A.P.J. Abdul Kalam Thursday urged Indian scientists to take up challenges beyond the earth like launching missions to Mars and other planets by collaborating with other countries. Delivering the annual Vikram Sarabhai Memorial lecture on ‘Dynamics of societal transformation’ here, Kalam said he visualised a habitat being established on Mars and mining of the moon and other planets by 2050. “India has to participate in such challenging mission with other countries. Thinking beyond our planet is an essential trait. The thought itself elevates the person. The person is transformed into a creative state.”
