NASA. Planetary scientists casting doubt on feasibility of plan to corral asteroid.

NASA9s new plan to capture a tiny asteroid in deep space and lodge it in the Earth-moon system so that astronauts can get their hands on it is certainly audacious. But instead of cheering, a lot of planetary scientists are dubious about the mission9s chances of success. They also say that the claimed side benefits, should the mission somehow succeed, are largely imaginary.
