Boeing's mysterious X-37B spaceplane, operated by the United States Air Force, has been a subject of intrigue and speculation since its first launch on April 22, 2010. Recently, SpaceX has entered the scene as the chosen launch provider for the X-37B missions, signifying a new era in the spacecraft's operational history.
The X-37B, also known as the Orbital Test Vehicle (OTV), is designed for extended missions in orbit, performing classified experiments and technology demonstrations.
Here is a video by Scott Manley, where he delves into the technical intricacies of the X-37B, shedding light on some of the mysteries surrounding this clandestine spaceplane.

The video provides insights into the spacecraft's design and capabilities.
The collaboration between Boeing and SpaceX has added a new dimension to the X-37B program. The OTV-5 mission marked the first time the spaceplane was launched atop a SpaceX Falcon 9, Block 4 rocket, underlining the growing partnership between traditional aerospace giants and innovative space startups. The upcoming OTV-7 mission is set to reach even greater heights as it rides into space on a Falcon Heavy.
As seen in the launch history of the X-37B, each mission has pushed the boundaries of space exploration, with durations ranging from 224 to 908 days in orbit. The extended periods spent in space highlight the spaceplane's versatility and its ability to endure the harsh conditions of orbital flight.
