In yet, it is for first time that Nasa, the US space agency, plans to train astronauts for a asteroid mission as sending them three million miles away in space for making contact with an asteroid.
This most dreadful but challenging manned mission will proceed by the end of the next decade in which the trainer so far more than limit of the Moon, would travel 50,000 miles per hour around the Sun for entire a year. The time limit for astronauts to stay on the asteroid is of up to 30 days.
