I'd like to send this letter by http://freeones.in.net/ freeones porn As it turns out, each of the 12 identified asteroids, or "easily retrievable objects," as the scientists deem them, could be brought back to Earth's orbit or nearby within a relatively short period of between 3 and 7.5 years. In order to find asteroids that would be good candidates for pickup, the scientists presumed that a 6-ton (US) spacecraft would be available, and that it would be able to carry enough liquid fuel to have 9-tons by the time it reached any one of the asteroids. "With a spacecraft of those characteristics, the total asteroid mass that could be transferred with the trajectories described in this paper is close to 400 tons," and between 2 to 5 meters in diameter, the authors write.
