For now, you'll either have to accept the official explanation, or just get comfortable with the knowledge that there's a mysterious space drone flying high above our heads, and only the USA military knows why.
As of 6:43am Tuesday ET, the X-37B spaceplane's fifth mission, dubbed the Orbital Test Vehicle (OTV-5), will have spent 719 days in orbit - just 11 days shy of a full two years circling the globe.
With each flight mission launched, the X-37B has remained in orbit for longer periods of time as the Air Force looks to push its endurance.

"The primary objectives of the X-37B are twofold; reusable spacecraft technologies for America's future in space and operating experiments which can be returned to, and examined, on Earth", the Air Force said in a statement.
The X-37B is clearly state of the art while up in space. All of the details about the X-37B mission are classified.
The previous OTV-4 mission was 718 days long.
Officials don't necessarily want to reuse the same X-37B plane multiple times, but the Air Force designed the crafts to try out new navigation systems as well as methods for reentering the Earth's atmosphere and for landing safely back on earth.
