Boeing X-37
The Boeing X-37 is like a mini spaceship that goes up really high in the sky. It looks like a tiny version of a space shuttle and it can be launched into space on top of a rocket. The X-37 is special because it can orbit the Earth for a very long time, like a giant robot in the sky.
Scientists use the X-37 to do experiments and learn more about space. They test new technology and see how it performs in space, where there is no air and no gravity. The X-37 can also change its orbit and land back on Earth like an airplane. This is important because it allows the scientists to bring back things they learn from space and study them more closely.
Some people think that the X-37 might be used by the military for secret missions, but we don't know for sure. Overall, the X-37 is a really cool way for scientists and engineers to learn more about space and how we can explore it.
