A plan to use the second-hand rocket in space to build space station silence after years of support again. According to the New Scientist magazine website on June 13 reported that the US National Aeronautics and Space Administration (NASA) recently signed with three private companies a $ 10 million investment contract to study the second-hand rocket into a space astronaut can accommodate a space experiment The feasibility of the room, trying to find a new second-hand rocket lord "home and rdquo ;.

As early as the 1970s, the first space station in the United States, "Space Laboratory" (Skylab) before the launch, known as the "father of modern space" American German rocket expert Weiner & middot; Feng & middot; Braun had suggested that two Saturn IB rockets (Saturn IB) were equipped with space station components and astronauts, were launched on the same day were launched. When both rockets enter the orbit, the astronauts can remotely release the remaining hydrogen in the rocket fuel tank in space and assemble the fuel tank into a space station. This idea of ​​separate emissions can reduce the weight of the rocket load, greatly reducing the cost of near-Earth orbit, rocket fuel tank also do not have to be abandoned to cause waste and pollution. The design was shelved for years, again by NASA's attention.

The NASA selected three commercial space companies are NanoCacks, the United Launch Alliance and Space Systems Loral. The joint launch alliance company will provide second-hand "Atlas 5" rocket, nano-cabin company to study how to convert second-hand rocket into space experiments and space for astronaut lives, and Laura Space Systems is responsible for the development of the robot in orbit assembly technology.

NASA founder and CEO Jeff & middot; Mambo said the new plan will provide a lower cost of space launch options, and compared with the ground assembly after the launch, the risk is even lower. Before used once was discarded "Atlas 5" Rocket, will be turned into a mini-space station. Once the research is successful, this low-cost space station will benefit the field of exploration of space such as Mars.
