The X-37B experimental orbital plane successfully completed an unmanned flight lasting two years.

The plane landed on May 7 at the strip at Cape Canaveral in Florida, intended for space shuttles and not used since the closure of the program.

The aircraft was put into orbit in May 2015 from the same Cape Canaveral with the help of the Atlas-5 launch vehicle,. In total, he spent about 700 days in orbit.

The plane carried out experiments for the rapid reaction forces of the American Air Force.

Before its launch, it was reported that experiments are being conducted as part of the work to create a new ion engine, but more details are classified.

This was the fourth launch of the X-37B into orbit in the framework of these studies. At the moment this is his longest flight.

The orbital plane X-37 was created in 1999. It was expected that it would be used to repair satellites in space, but then the program was transferred to the US Air Force and classified. This is reported by the Air Force.
