X-37B is an experimental drone called OTV (Orbital Test Vehicle) with a total length of 8.8 meters, a height of 2.9 meters, and a wingspan of 4.6 meters. The U.S. Air Force, based on the research of reusable spacecraft technology for the future of the United States, advanced guidance systems, navigation and control, thermal protection systems, avionics , high temperature materials and sealability in orbit around the earth Announced that X-37B is used to collect data on reusable insulators, automatic orbital flight, atmospheric reentry and landing. The space flight experiment on X-37B will be the fifth time in this mission, but what kind of data was actually collected in each mission and details on the progress status have not been disclosed. It is called speculation that 'is it used for the development of?'

Launched on September 7, 2017 by SpaceX 's Falcon 9 rocket, the X-37B broke the flight record of 717 days 20 hours 42 minutes that the aircraft set up during the previous mission as of August 26, 2019 . Since X-37B is still in orbit around the earth at the time of article creation, we continue to update the record of the continuous flight time.

However, this record is only for X-37B. As the longest record of space flight, Voyager No.1 and No.2 that have been drifting in outer space since August 5, 1977, and have been drifting in the space, will be the top.

The flight days in each mission of X-37B continue to increase steadily to 225 days, 468 days, 675 days, and 717 days, and the total number of flight days from the 1st to the 5th mission at the time of article publication is 2804 days. The US Air Force has been experimenting in outer space for a long time.
