Before we reopened Eden Park Bed and Breakfast ,the wife and I lived the the USA for 6 years. We saw a lot of things and the influence of the military is everywhere; so I find the X-37B very cool.

The X-37B unmanned space plane will be undergoing its third launch, set upon a top secret mission by the Air Force. The spacecraft has a payload capacity about the size of a small truck bed, the contents of which are unknown.
X-37B will be hitching a ride aboard United Launch Alliance’s Atlas V rocket at 1:03 p.m. on Tuesday. Although the launch window is open until just after 6:00 p.m., there is just a 30 percent chance of favorable weather conditions for liftoff.
The mini-space shuttle is about a quarter of the size of the retired NASA orbiters and is both a reusable and a robotic vehicle.
The vehicle has no crew cabin, no support life systems, and is solar-powered, designed to remain up in orbit for 270 days. Although its max life is supposed to be 270 days, the second X-37B mission flew for 469 days.
X-37B is also famous for being able to launch, orbit the Earth and re-enter our planet’s atmosphere, all autonomously.
Many theorists have opinions on what the super secret spacecraft is tasked with doing. Some believe that the X-37B harbors the capability of striking anywhere in the world in less than an hour.
Some believe that the vehicle is meant to keep an eye on China and Russia, particularly China’s new space endeavors. Amateur astronomers keeping an eye on X-37B’s orbital patterns say that the spacecraft is following closely on China’s Tiangong 1 orbit.
Others simply believe that X-37B is just a platform to allow the Air Force to perform experiments in space, or that it is a test bed for advanced sensors or secret missions.
Whatever it does this is one seriously cool piece of hardware produced by the US of A.
