Abstract in English:
Since the dawn of the space era in 1957, space science and technology have enhanced our knowledge of Earth, atmosphere, and outer space. They have improved the quality of life for the human race. Our space vision for the next 50 years has to consolidate these benefits and expand them further to address crucial issues faced by humanity in energy, environment, water, and minerals. Above all, we have to keep upper most in our mind the need for an alternate habitat for the human race in our solar system. The crucial mission for the global space community is to realize a dramatic reduction in the cost of access to space.
