The X-37B plane in orbit, called OTV-5, and it was launched to space in September 2017 on a SpaceX Falcon 9 rocket.

US Air Force’s X-37B: Recently, on 26th August 2019, a United States Air Force operated X-37B space plane, has broken a new spaceflight duration record. It is a reusable robotic spacecraft, which is the fifth in its series of Orbital Test Vehicle (OTV) mission. On 26th August, it completed 719 days of orbital spaceflight and is still going. With its achievements, it became the longest mission for any secretive military test program.

Over the past decade United States Air Force has launched five uncrewed X-37B spaceplanes into the orbit, and each mission was longer than its predecessor. OTV-4, the previous mission could reach the mark of 717 days, 20 hours and 42 minutes. Its predecessor OTV-3 lasted for 675 days, OTV-2 for 468 days and OTV-1 for 224 days. For now, no end date of the mission is specified by the officials. What we know is just that, the spacecraft will return back to Earth only after it has completed all its objectives. These Objectives are still secretly being guarded by the US Military.

Due to its secrecy, the X-37B program attracts a lot of public interest because of that secrecy. This attraction has created curiosity in many amateur astronomers. These curious astronomers have spotted the spacecraft through telescopes.

US Air Force’s X-37B: A vision that is becoming reality, reusable spaceflight technology. According to sources, the US military is using these planes to develop reusable spaceflight technology. The Air Force has designed such aircraft to try out new dimensions of navigation systems and methods to reenter the Earth’s atmosphere and for landing safely on the ground.

The X-37B is quite popular among the space explorers due to its unique design. The bullet-shaped black and white plane is just 8.9 meters long with sturdy wings. It looks like a miniature space shuttle. They are launched through powerful rockets and while returning back, they are capable of horizontal landing like any commercial airplane.

US Air Force’s X-37B: The X-37B is a derivative of Boeing X-40 which had its first flight in 2006. Since then, five OTV missions have been taken place and the latest is, OTV-5, which was launched on September 7, 2017.

These spacecraft are designed to perform ex-situ experimentation of the objects in space. And again the nature of these experiments are still unknown. But things are no so simple here, how can speculators stop guessing the desired objectives of these missions. In theories, it is guessed that these missions could be involved in spying activities or testing out a space weapon for more continue reading on techhundred.
