The American military spacecraft, which is powered by solar energy, has been traveling in space for more than 720 days. It almost three times exceeded the initial duration of his mission, which was 270 days. However, what exactly the spaceship does is not reported to anyone.
Using a mysterious spacecraft scientists test weapons or conduct orbital observation operations. It is noteworthy, however, that in 2010, the Americans noted that the program does not provide for any “offensive capabilities”.
However, no matter what the purpose of the unmanned instrument is, it is known that at first its mission was designed for only 270 days. A significant excess of the duration of the spacecraft’s stay in space is a big win for all aircraft equipped with solar panels
