Artists impression of X-37B with solar panels (Picture 1) Kimmo Huosionmaa The term “space station” is not very well understood in the literature.It actually means the structure, what has long-term being in space, and some of those structures are quite small, the laboratories of those vehicles are remotely controlled. The X-37B and other space shuttles can also operate as miniaturized space stations, and they can stay in orbital trajectory very long time. Because they are unmanned, there would make investigations without risking human lives, and that would give more usages for those devices. When the mission is accomplished that space laboratory would land back to earth. When we are talking about biological experiments, what are made with those small size spacecraft, they can operate years in space. And there would be no risk for human lives. In those remotely controlled laboratories could be released mosquitos and other bugs, and observe their population in the spacecraft...
